Understanding overall shoulder function and health: the value of specific quantitative vs. qualitative shoulder range of motion on patient-reported outcome measures.

HYPOTHESIS AND BACKGROUND: It is known that, though widely used, shoulder range of motion (ROM) measurements are not standardized and have a high rate of intra- and interobserver differences. Particularly, the inconsistency in quantitative and qualitative measurements and their relationship to patient-reported outcome measures (PROMs) make shoulder health difficult to determine. METHODS: This was a prospective study of 147 patients who presented with a chief complaint of shoulder pain to the orthopedic sports medicine and shoulder clinic of a single fellowship-trained surgeon. Measured by 1 examiner, quantitative ROM measurements were taken with a goniometer and qualitative ROM measured by the anatomic level that the patient could reach. The following PROMs were used as well: American Shoulder and Elbow Surgeons shoulder score, Single Assessment Numeric Evaluation, Shoulder Pain and Disability Index, Oxford Shoulder Score, Disabilities of the Arm, Shoulder, and Hand questionnaire, 12-Item Short Form Health Survey, and Patient-Reported Outcomes Measurement Information System pain interference short form 6a (PROMIS 6a). Statistical analysis was performed with SPSS using the Pearson correlation and 2-sample t test. The Benjamini-Hochberg correction was used to determine the P value at which statistical significance was reached to correct for multiple comparisons. RESULTS: Qualitative internal rotation (IR) (the hand behind back reach test) and qualitative forward flexion (FF) correlated with all goniometer angle measurements and PROMs (both shoulder and general health scores). These qualitative measures proved to be an appropriate proxy for IR and FF goniometer measurements. Qualitative external rotation (ER) was not a good substitute for quantitative ER measurement. Quantitative ER correlated with all PROMs. As ROM increased when measured by quantitative ER, qualitative IR, and qualitative FF, shoulder and general health PROMs incrementally increased as well. DISCUSSION/CONCLUSIONS: Qualitative IR measurement, the hand-behind-back reach test, is an adequate substitution for IR goniometer angle as well as a strong representation of global shoulder ROM, shoulder health, and general health while factoring in patient age. Qualitative FF measurement is also an appropriate proxy for quantitative FF and represents global shoulder and general health without factoring in age. Quantitative ER, via goniometer angle, is a better assessment of the shoulder than qualitative ER and is a representation of overall shoulder and general health. We recommend the use of quantitative ER, qualitative IR, and qualitative FF measurements to best understand a patient's overall shoulder health and its impact on their overall health.

A comparison of quantitative and qualitative shoulder range of motion with patient-reported outcomes.

BACKGROUND: The evaluation of shoulder function requires a combination of physical examination of shoulder range of motion and measures of functional outcome measures. Although efforts have been made to define range of motion for clinical evaluation with respect to functional outcomes, a disconnect still exists when defining a successful outcome. We aim to compare quantitative and qualitative measures of shoulder range of motion with patient-reported outcome measures. METHODS: Data from 100 patients who presented to the office of a single surgeon with a chief complaint of shoulder pain were evaluated for this study. Evaluation included American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Single Assessment Numeric Evaluation relative to the shoulder of interest, demographic information, and range of motion in the shoulder of interest. RESULTS: Internal rotation angle did not correlate with patient-reported outcomes, whereas external rotation and forward flexion angles did. Qualitative internal rotation as measured by hand-behind-back reach demonstrated a weak to moderate correlation with patient-reported outcomes, and a significant difference in global range of motion and functional outcome measures were identified in patients who can or cannot reach above the belt line or to the thoracic spine. Qualitative assessment of forward flexion demonstrated that patients who can reach specific anatomic landmarks have significantly improved functional outcome measures, and the same is true when comparing patients who can externally rotate past neutral. CONCLUSIONS: Hand-behind-back reach can be used as a clinical marker of global range of motion and functional outcome measures for patients with shoulder pain. Goniometer measurement of internal rotation has no relationship with patient-reported outcomes. Forward flexion and external rotation assessment with qualitative cutoffs can additionally be used clinically to determine functional outcome for patients with shoulder pain.

Clinical and radiological outcomes in lateralized versus nonlateralized and distalized glenospheres in reverse total shoulder arthroplasty: a randomized control trial.

BACKGROUND: Lateralization in reverse total shoulder arthroplasty (RTSA) has been used to theoretically offer the potential benefits of reduced scapular notching rates and improved stability and range of motion (ROM), particularly external rotation. The aim of this study was to compare ROM and clinical and radiographic outcomes between patients who underwent RTSA with a lateralized vs. a nonlateralized and distalized glenosphere. METHODS: A single-surgeon randomized control trial was conducted comparing 27 patients with a lateralized glenosphere and 26 patients with a nonlateralized and distalized glenosphere. A total of 66 patients were enrolled, 2 patients died before 2-year follow-up, 4 patients withdrew from the study, and 7 patients were lost to follow-up. All patients in the lateralized group received 6 mm of lateralization through the glenosphere. Participants represented a population presenting to an orthopedics sports medicine clinic with any indication for RTSA including revision arthroplasty. Patients completed preoperative and routine postoperative functional outcome measures 3, 6, 12, and a minimum of 24 months postoperatively, including American Shoulder and Elbow Surgeons, Patient-Reported Outcomes Measurement Information System Physical Function Upper Extremity, and Activities of Daily Living Requiring Active External and Internal Rotation assessments. Patients were also evaluated with ROM and radiographic measurements. The primary outcome of interest in this study was ROM, particularly external rotation. RESULTS: At 2-year follow-up, both groups had significant improvement in their American Shoulder and Elbow Surgeons, Patient-Reported Outcomes Measurement Information System Physical Function Upper Extremity, and Activities of Daily Living Requiring Active External and Internal Rotation scores with no significant difference observed between the groups. There were no statistically significant differences in incidence of scapular notching or acromial stress fractures. ROM in both groups improved significantly at their 2-year assessment with the only exception to this being external rotation at 90° of abduction in the nonlateralized and distalized group (39° ± 31° vs. 48° ± 24°, P = .379). CONCLUSIONS: Regardless of glenosphere lateralization status, patients in both groups had significant improvement in functional outcome scores and ROM, and there were no significant differences observed between the groups at 2-year follow-up. Longer follow-up is needed to determine the effect of implant design on late complications, long-term outcomes, and implant retention.

Graft choice or drilling technique does not influence outcomes of ACL reconstruction in patients over forty-five.

PURPOSE: To evaluate whether graft-type and tunnel location in ACL reconstruction impact patient-reported outcomes in individuals over the age of 45. METHODS: From 2015 to 2018, patients over 45 years old undergoing primary ACL reconstruction without multi-ligamentous injuries were enrolled in an institutional registry. Baseline International Knee Documentation Committee (IKDC) subjective scores, Knee Injury and Osteoarthritis Outcome Scores (KOOS), Marx Activity Scale, and patient characteristics were collected. Follow-up occurred at a minimum of two years to obtain patient-reported outcomes. RESULTS: Of the 51 patients who qualified for the study, 44 (86.3%) patients were available at a minimum of two years after surgery date (range 24-60 months). Average age at time of surgery of the available patients was 51.6 ± 4.87 (range 45-66). Between femoral tunnel drilling methods, there were no differences in the proportion of patients achieving clinically significant improvement or post-operative outcome scores. While patients who received patellar tendon autografts were more likely to achieve clinically significant improvement in the KOOS sports subscale, there were no other differences in outcomes measures between graft types. Two patients had a retear of their graft, and an additional five patients complained of subjective instability. CONCLUSIONS: In patients over the age of 45, neither the method used to create the femoral tunnel nor the graft type used in ACL reconstruction caused a significant difference in post-operative PROMs with a minimum of two years of follow-up. LEVEL OF EVIDENCE: Therapeutic IV, Case Series.

Patient-Reported Outcomes Measurement Information System Scores Are Inconsistently Correlated With Legacy Patient-Reported Outcome Measures in Shoulder Pathology: A Systematic Review.

PURPOSE: To evaluate the current literature regarding Patient-Reported Outcomes Measurement Information System (PROMIS) and its correlation to legacy patient-reported outcomes measures (PROMs) in 5 domains: (1) rotator cuff disease, (2) shoulder instability, (3) shoulder arthroplasty, (4) proximal humerus fractures, and (5) glenohumeral arthritis. The secondary purpose is to evaluate the floor and ceiling effects, the number of questions, and time needed to complete PROMIS and legacy PROMs in shoulder care. METHODS: A systematic review of the available literature on PROMIS scores in shoulder care was performed. This review was accomplished per PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. RESULTS: A total of 11 studies that reported data on 1485 patients met inclusion criteria. There was a strong correlation between general function PROMs and the PROMIS PF for patients with rotator cuff disease, shoulder instability, shoulder arthroplasty, and proximal humerus fractures. In addition, there was a strong correlation between PROMIS UE and legacy PROMs in patients with rotator cuff injury and shoulder instability. PROMIS instruments asked fewer questions than legacy PROMs (9.46 vs 12.99, respectively), took less time to complete (88.21 vs 96.53 seconds, respectively), had less floor effects in both PROMIS PF and UE (0.17% and 0.62% vs 2.89%, respectively), and had lower ceiling effects for PROMIS PF but not PROMIS UE assessments (0.17% and 6.37% vs 1.89%, respectively). CONCLUSIONS: This systematic review demonstrated PROMIS instruments have varying correlations with legacy PROMs measures for patients with rotator cuff disease, shoulder instability, shoulder arthroplasty, and glenohumeral arthritis. PROMIS instruments do measure clinical outcomes faster and with fewer questions. Other than PROMIS UE v1.2 ceiling effects, PROMIS instruments have lower rates of floor and ceiling effects.

Factors that influence inpatient satisfaction after shoulder arthroplasty.

BACKGROUND: It is important to distinguish satisfaction regarding the outcome of care and satisfaction with the delivery of care. The Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys are modern assessments of hospitals and providers of delivery of care. The purpose of this study was to report inpatient satisfaction according to Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS) scores after shoulder arthroplasty and to determine factors that influence them, as well as their correlation with surgical expectations, pain perception, quality of life, surgical setting, and functional outcomes. METHODS: All patients scheduled for a shoulder arthroplasty were prospectively asked to complete a demographic and initial shoulder assessment form, a shoulder surgery expectations survey, a pain catastrophizing scale, the SF-12 (12-item Short Form) survey, and a resiliency form (Resilience Scale 11). Patient satisfaction was measured with the CG-CAHPS and HCAHPS surveys. Legacy forms, patient-specific factors, type of surgery performed, location of surgery, length of hospital stay, and discharge disposition were evaluated on their ability to predict these survey scores. Linear regression was used to calculate correlations and predictions of continuous variables, and logistic regression was used to compared the satisfied vs. unsatisfied cohorts. RESULTS: The average HCAHPS and CG-CAHPS satisfaction scores for the population were 74.7 ± 20.7 and 82.1 ± 19.4, respectively. Nonsmokers had a mean HCAHPS score of 77.7 ± 22.0, whereas current smokers reported a mean of 59.6 ± 5.2 (P = .03). Patients who were discharged home had a mean HCAHPS score of 77.3 ± 21.9, whereas those discharged to a skilled nursing facility reported a mean of 59.3 ± 6.6 (P = .05). These same groups also had significantly higher odds of being satisfied with the hospital. No significant differences or higher odds were seen for comparisons between overall CG-CAHPS satisfaction and any of the patient-specific factors tested. There was no significant correlation between age, length of stay, pain (pain catastrophizing scale), resiliency (Resilience Scale 11), expectations (shoulder surgery expectations survey), or function (SF-12) and both the HCAHPS and CG-CAHPS satisfaction scores. CONCLUSION: Overall, 37 patients (74%) had CG-CAHPS scores that indicated satisfaction and 34 patients (68%) had HCAHPS scores that indicated satisfaction. Nonsmokers and patients discharged home after surgery report higher levels of inpatient hospital (HCAHPS) satisfaction after shoulder arthroplasty. Patients with high preoperative surgical expectations, pain perception, and resiliency are not generally more satisfied with the hospital or clinician. Preoperative diagnosis, location of surgery, and length of stay do not reliably impact satisfaction with the hospital or clinician. Inpatient HCAHPS and CG-CAHPS satisfaction does not correlate with legacy functional outcome measures and, therefore, may not be predictive of long-term functional outcomes.

Does preoperative diagnosis impact patient outcomes following reverse total shoulder arthroplasty? A systematic review.

BACKGROUND: The indications for reverse total shoulder arthroplasty (rTSA) have expanded to include the treatment of a wide variety of shoulder pathologies, and there may be significant differences in patient outcomes based on preoperative diagnosis. METHODS: A systematic review of the orthopedic literature contained in the PubMed, Cochrane, and Embase databases was performed on November 14, 2019. Studies investigating rTSA indicated for 7 distinct preoperative diagnoses (massive rotator cuff tear [MCT] without glenohumeral osteoarthritis [GHOA], MCT with GHOA or cuff tear arthropathy, primary GHOA, inflammatory arthritis with MCT, failed shoulder arthroplasty, proximal humeral fracture [PHF], and sequelae following PHF) were included. The main outcomes of interest included functional outcomes (abduction, external rotation, and forward flexion) and patient-reported outcome measures (American Shoulder and Elbow Surgeons shoulder score and Constant-Murley score). Because of significant variation in measurement and reporting, data on internal rotation were not extracted. In addition, radiographic outcomes and complication rates were extracted and recorded for each of the included studies. RESULTS: In total, 47 studies, comprising 2280 patients, met the inclusion criteria. Significant improvements in functional outcomes and patient-reported outcome measures were found across the preoperative diagnostic groups. There were no significant differences between the diagnostic groups regarding improvement between preoperative and postoperative values for the outcomes of interest, with the exception that the inflammatory arthropathy group had significantly less improvement in the Constant-Murley score than the primary GHOA and revision arthroplasty groups. Although there were few differences in improvement between groups, there were significant differences regarding the level of postoperative functional performance, which was not as consistent in the context of trauma or revision operations (ie, complex PHF, fracture sequela, and revision arthroplasty groups). CONCLUSION: Reverse total shoulder arthroplasty can provide reliable improvement in clinical outcomes regardless of preoperative diagnosis, with few differences across diagnostic groups regarding preoperative to postoperative improvement. The groups with primary GHOA and MCTs with or without GHOA demonstrated the most reliable postoperative functional outcomes of the examined diagnostic groups. Postoperative outcomes were not as consistent in the context of trauma or revision operations, and these groups may benefit from a variety of modern advancements in rTSA, although further research into these modalities for these groups is needed. Finally, rTSA remains an important treatment option in the context of rheumatoid arthritis, with similar outcomes and complication rates compared with the 6 other operative indications.

Does preoperative disease severity influence outcomes in reverse shoulder arthroplasty for cuff tear arthropathy?

BACKGROUND: The degree of symptomatic disease and functional burden has been demonstrated to influence patient results and satisfaction in total hip and knee arthroplasty. Although the relationship between preoperative diagnosis and patient outcomes has been an area of study for reverse total shoulder arthroplasty (RTSA), the influence of the progression of cuff tear arthropathy (CTA) has not yet been examined. The purpose of this study was to evaluate whether preoperative radiographic disease burden and scapular geometry impact patient outcomes and satisfaction in a cohort of patients with CTA treated with RTSA. METHODS: Eighty-six patients were treated for CTA with RTSA performed by the senior author (B.G.) between September 2016 and September 2018 and were enrolled in an institutional registry. At the time of initial evaluation, the baseline American Shoulder and Elbow Surgeons (ASES) score, patient demographic characteristics, history of shoulder surgery, and presence of pseudoparalysis were collected. Radiographs were obtained to evaluate the critical shoulder angle, acromial index, and progression of CTA as assessed by Hamada grading and the Seebauer classification. Patients were contacted to reassess the ASES score and their satisfaction with the improvement in their shoulder function. RESULTS: A total of 79 patients (91.6%) were available for evaluation at a minimum of 24 months of follow-up. Multivariate logistic regression modeling revealed that scapular geometry measurements (critical shoulder angle and acromial index) and the degree of CTA (Seebauer and Hamada classifications) were not associated with worse outcomes as assessed by the ASES score. However, degenerative changes as assessed by the Hamada grade (odds ratio, 0.13 [95% confidence interval, 0.02-0.86]; P = .03) and preoperative ASES score (odds ratio, 1.04 [95% confidence interval, 1.01-1.07]; P = .008) were independently associated with higher satisfaction at 24 months of follow-up. CONCLUSION: The results indicate that patients with greater CTA disease progression did not show differing outcomes after RTSA compared with patients with milder disease. In contrast, both poorer preoperative function and degenerative changes as assessed by the Hamada classification were associated with greater satisfaction after RTSA for CTA. Given the broad spectrum of disease in CTA, there is likely a corresponding range in patient expectations that requires further study to maximize patient satisfaction.

Reliability of the modified Walch classification for advanced glenohumeral osteoarthritis using 3-dimensional computed tomography analysis: a study of the ASES B2 Glenoid Multicenter Research Group.

BACKGROUND: Variations in glenoid morphology affect surgical treatment and outcome of advanced glenohumeral osteoarthritis (OA). The purpose of this study was to assess the inter- and intraobserver reliability of the modified Walch classification using 3-dimensional (3D) computed tomography (CT) imaging in a multicenter research group. METHODS: Deidentified preoperative CTs of patients with primary glenohumeral OA undergoing anatomic or reverse total shoulder arthroplasty (TSA) were reviewed with 3D imaging software by 23 experienced shoulder surgeons across 19 institutions. CTs were separated into 2 groups for review: group 1 (96 cases involving all modified Walch classification categories evaluated by 12 readers) and group 2 (98 cases involving posterior glenoid deformity categories [B2, B3, C1, C2] evaluated by 11 readers other than the first 12). Each case group was reviewed by the same set of readers 4 different times (with and without the glenoid vault model present), blindly and in random order. Inter- and intraobserver reliabilities were calculated to assess agreement (slight, fair, moderate, substantial, almost perfect) within groups and by modified Walch classification categories. RESULTS: Interobserver reliability showed fair to moderate agreement for both groups. Group 1 had a kappa of 0.43 (95% confidence interval [CI]: 0.38, 0.48) with the glenoid vault model absent and 0.41 (95% CI: 0.37, 0.46) with it present. Group 2 had a kappa of 0.38 (95% CI: 0.33, 0.43) with the glenoid vault model absent and 0.37 (95% CI: 0.32, 0.43) with it present. Intraobserver reliability showed substantial agreement for group 1 with (0.63, range 0.47-0.71) and without (0.61, range 0.52-0.69) the glenoid vault model present. For group 2, intraobserver reliability showed moderate agreement with the glenoid vault model absent (0.51, range 0.30-0.72), which improved to substantial agreement with the glenoid vault model present (0.61, range 0.34-0.87). DISCUSSION: Inter- and intraobserver reliability of the modified Walch classification were fair to moderate and moderate to substantial, respectively, using standardized 3D CT imaging analysis in a large multicenter study. The findings potentially suggest that cases with a spectrum of posterior glenoid bone loss and/or dysplasia can be harder to distinguish by modified Walch type because of a lack of defined thresholds, and the glenoid vault model may be beneficial in determining Walch type in certain scenarios. The ability to reproducibly separate patients into groups based on preoperative pathology, including Walch type, is important for future studies to accurately evaluate postoperative outcomes in TSA patient cohorts.

Outcomes of Reverse Total Shoulder Arthroplasty in Patients 60 Years of Age or Younger: A Systematic Review.

PURPOSE: Reverse total shoulder arthroplasty (RTSA) has been traditionally performed in elderly, low-demand patients. However, indications for RTSA are expanding, and patients who potentially benefit from this procedure are not restricted to those who are elderly. The purpose of this review was to summarize reported outcomes of RTSA in patients aged 60 years or younger. METHODS: We performed a systematic review of the literature to search for outcomes of RTSA in patients aged 60 years or less. Inclusion criteria were studies reporting clinical and/or functional outcomes of RTSA in patients aged 60 years or less with follow-up of greater than 2 years. Cadaveric studies and studies including patients aged greater than 60 years were excluded. Outcomes of interest were range of motion, functional scores (Constant, American Shoulder and Elbow Surgeons, Simple Shoulder Test, and visual analog scale for pain), implant survival, and complications. RESULTS: Four studies with a total of 193 patients met inclusion criteria with mean durations of follow-up of 34 to 140.4 months. At the final follow-up, all studies showed significant improvements in flexion, abduction, and all reported functional scores. Mean postoperative flexion and abduction ranged from 85.7° to 134° and from 79° to 111°, respectively. Implant survival ranged from 87.5% to 94.3% at the latest follow-up. Complication rates ranged from 15% to 39.1%. CONCLUSIONS: Early clinical and functional outcomes of RTSA in patients aged 60 years or less are favorable. Long-term functional results and implant survival rates of RTSA are comparable to previous data from older patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Management of irreparable massive rotator cuff tears: a systematic review and meta-analysis of patient-reported outcomes, reoperation rates, and treatment response.

BACKGROUND: There is no consensus on the treatment of irreparable massive rotator cuff tears. The goal of this systematic review and meta-analysis was to (1) compare patient-reported outcome scores, (2) define failure and reoperation rates, and (3) quantify the magnitude of patient response across treatment strategies. METHODS: The MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and Scopus databases were searched for studies including physical therapy and operative treatment of massive rotator cuff tears. The criteria of the Methodological Index for Non-randomized Studies were used to assess study quality. Primary outcome measures were patient-reported outcome scores as well as failure, complication, and reoperation rates. To quantify patient response to treatment, we compared changes in the Constant-Murley score and American Shoulder and Elbow Surgeons (ASES) score with previously reported minimal clinically important difference (MCID) thresholds. RESULTS: No level I or II studies that met the inclusion and exclusion criteria were found. Physical therapy was associated with a 30% failure rate among the included patients, and another 30% went on to undergo surgery. Partial repair was associated with a 45% retear rate and 10% reoperation rate. Only graft interposition was associated with a weighted average change that exceeded the MCID for both the Constant-Murley score and ASES score. Latissimus tendon transfer techniques using humeral bone tunnel fixation were associated with a 77% failure rate. Superior capsular reconstruction with fascia lata autograft was associated with a weighted average change that exceeded the MCID for the ASES score. Reverse arthroplasty was associated with a 10% prosthesis failure rate and 8% reoperation rate. CONCLUSION: There is a lack of high-quality comparative studies to guide treatment recommendations. Compared with surgery, physical therapy is associated with less improvement in perceived functional outcomes and a higher clinical failure rate.

Return to Sport Following Revision Anterior Cruciate Ligament Reconstruction in Athletes: A Systematic Review.

PURPOSE: To report the rate of return to sport following revision anterior cruciate ligament (ACL) reconstruction in athletes. METHODS: A systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted for athletes undergoing revision ACL reconstruction at a minimum 1-year follow-up. The primary outcome measure was return to sport following revision ACL reconstruction. Secondary outcomes were International Knee Documentation Committee score, Knee Injury and Osteoarthritis Outcome Score, Tegner and Lysholm scores, KT-1000 arthrometer measurements, and rates of ACL rerupture. A subjective analysis was performed, and data were summarized using forest plots, ranges, and tables. RESULTS: Thirteen studies met the inclusion criteria. The rate of return to sport at any level ranged from 56% to 100%. The rate of return to sport at preinjury level ranged from 13% to 69%. The average time to return to sport ranged from 6.7 to 12 months. The average patient-reported outcome scores ranged from 43% to 86% (International Knee Documentation Committee score), 45% to 95% (Knee Injury and Osteoarthritis Outcome Score), 4.3 to 9 (Tegner), and 84% to 91% (Lysholm). KT-1000 arthrometer measurements ranged from 1.2 to 3.1 mm. Rates of ACL rerupture ranged from 0% to 20%. CONCLUSIONS: This systematic review demonstrated a relatively high rate of return to sport at any level in patients who underwent revision ACL reconstruction, but a relatively low rate of return to sport at preinjury level of play. Patient-reported outcomes were favorable, showing improvement at follow-up from preoperative scores. Rates of ACL rerupture were high relative to those reported for primary ACL reconstruction. This study suggests that athletes may have difficulty resuming their previous level of sport following revision ACL reconstruction but have a good chance of returning to a lower level of play. LEVEL OF EVIDENCE: Level IV, systematic review of Level II-IV studies.

Return to Sport and Sports-Specific Outcomes After Osteochondral Allograft Transplantation in the Knee: A Systematic Review of Studies With at Least 2 Years' Mean Follow-Up.

PURPOSE: To report current data on return-to-sport rates and sports-specific patient-reported outcomes after osteochondral allograft (OCA) transplantation for cartilage defects of the knee. METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines that included studies from 1975 to 2018 with a minimum 2-year mean follow-up that reported return-to-sport rates or sports-specific patient-reported outcomes. Outcomes, reoperations, and complications were provided in table format, and a subjective analysis was performed. RESULTS: This review included 13 studies with 772 patients who underwent OCA transplantation at a mean of 24 to 91 months' follow-up. The return-to-sport rate ranged from 75% to 82%. For patient-reported outcomes, the Knee Injury and Osteoarthritis Score Sport increased in 4 studies, the Tegner activity scale score increased in 3 studies but decreased in 1, and the Marx activity scale score increased in 1 study but decreased in 2. Studies reporting improvements in the Cincinnati Knee Score and Knee Injury and Osteoarthritis Score Sport reached the minimal clinically important difference. The reoperation rate was high (ranging from 34% to 53% in more than half of studies), with reoperations primarily performed for loose body removal or debridement. CONCLUSIONS: This systematic review of 13 studies suggests that OCA transplantation for cartilage defects allows most athletes to return to sport (range, 75%-82%). Most studies reported improvements in sports-specific patient-reported outcomes at follow-up and reached the minimal clinically important difference. However, the reoperation rate was high in several studies, with a large percentage of patients requiring loose body removal or debridement. The long-term survival of the allografts is largely unknown, but this study suggests OCA transplantation consistently improves function in athletes with chondral injuries. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.

Type 2 retear after arthroscopic single-row, double-row and suture bridge rotator cuff repair: a systematic review.

AIM/PURPOSE: To provide a systematic review of the literature on patterns of retear after single-row (SR), double-row (DR) and suture bridge (SB) techniques. METHODS: The PubMed and MEDLINE databases were searched for published articles reporting both repair technique and retear pattern. Studies in languages other than English, those reporting open rotator cuff repair as the index procedure, as well as animal and cadaveric studies and those which did not describe patterns of retear, were excluded. MINORS scoring system was used to quantify potential bias in each study. Retears were classified into type 1 (failure at the tendon-bone interface) and type 2 (medial cuff failure). For all studies included, number and type of retears after different repair techniques were reported and analyzed. RESULTS: Fourteen studies were included yielding a total of 260 rotator cuff retears. Repair technique had a significant impact on the estimated incidence rate of type 2 retear (p = .001). The estimated incidence rate of type 2 retear was 24% with SR (95% CI 14-38%), 43% with DR (95% CI 22-66%), 62% with SB (95% CI 54-70%) and 38% with SB (95% CI 23-57%). CONCLUSION: Despite the lack of high-quality evidence, this study suggests that DR and SB techniques increase the risk of medial cuff failure. Modifications in surgical techniques in both DR and SB repairs can help decrease that risk. LEVEL OF EVIDENCE: Level IV, systematic review of investigations including level IV.

Risk factors associated with ACL registry compliance: can we predict who will follow-up?

PURPOSE: The purpose of this study was to determine patient factors that influence patient compliance to fill out anterior cruciate ligament reconstruction (ACLR) registry forms. METHODS: Patients prospectively enrolled in the ACLR registry at a single institution were retrospectively reviewed. Patients who were followed up for at least 6 months were included. Patients who did not fill out initial registry forms were excluded. Patients were asked to fill out forms preoperatively and at 6, 12 and 24 months postoperatively. The impacts of age, race, employment status, medical insurance, smoking status, driving distance to the hospital and importance to return to the same level of sporting activity were analyzed against patient compliance (yes/no) to complete registry forms at the respective follow-ups. Multivariate analysis was performed to analyze variables at 6 and 12 months postoperatively. The numbers of patients who were followed up for more than 24 months were too low to run a multivariate analysis, so only univariate analysis was performed on this cohort. RESULTS: A total of 221 patients filled out the initial preoperative forms at least 6 months before data gathering was commenced and were included. At 6 months postoperatively, none of the variables significantly influenced patient compliance. At 12 months, younger age and longer driving distance to the hospital had a significant negative impact on compliance [OR per year: 0.92 (0.85-0.99), p = 0.0237; OR per mile: 1.01 (1, 1.01), p = 0.0297]. Patients who filled out registry forms at 6 months were significantly more compliant at 12 months postoperatively (p < 0.0001). At 24 months, the influence of age remained significant (p = 0.0262) and, additionally, patients who initially noted that it was important for them to return to the same level of sports were significantly less compliant (p = 0.0367). CONCLUSION: Younger age and longer driving distance to the hospital were significantly associated with less compliance to fill out ACLR registry forms at 12 months postoperatively. Patient perspectives on the importance to return to the same level of sports were inversely related to compliance at 24 months postoperatively. This information can be utilized to improve compliance in future studies as we have potentially identified patients that can be viewed as "at-risk" for registry noncompliance.

Correlation of Patient-Reported Outcome Measurement Information System Physical Function Upper Extremity Computer Adaptive Testing, With the American Shoulder and Elbow Surgeons Shoulder Assessment Form and Simple Shoulder Test in Patients With Shoulder Pain.

PURPOSE: To evaluate the Patient-Reported Outcome Measurement Information System Physical Function Upper Extremity Computer Adaptive Testing (PROMIS PFUE CAT) measurement tool against the already validated American Shoulder and Elbow Surgeons Shoulder Assessment Form (ASES) and the Simple Shoulder Test (SST) in patients presenting with shoulder pain and determine the responder burden for each of the 3 surveys. METHODS: Ninety patients presenting with shoulder pain were asked to fill out the ASES, SST, and PROMIS PFUE CAT. The time for completion of each survey was measured to determine responder burden, and the Pearson correlation between the 3 instruments was defined as excellent (r > 0.7), excellent-good (0.61 ≤ r ≤ 0.7), good (0.31 ≤ r ≤ 0.6), and poor (0.2 ≤ r ≤ 0.3). RESULTS: The PROMIS PFUE CAT showed an excellent correlation with the SST (r = 0.82, P < .001) and ASES (r = 0.72, P < .001). The average time to complete SST, ASES, and PROMIS PFUE CAT was 92.8 ± 35.8, 142.3 ± 60.1, and 61.3 ± 28.8 seconds, respectively. The time to complete the PROMIS PFUE CAT was significantly less than both the SST (P < .001) and ASES (P < .001). CONCLUSIONS: The PROMIS PFUE CAT showed an excellent correlation with the previously validated ASES and SST in patients with shoulder pain. The time saving of the PROMIS PFUE CAT was found to be smaller than that of the ASES and SST but shows that moving forward, using the PROMIS PFUE CAT would not place any additional burden on the patient filling out the survey. The lack of ceiling or floor effects with the PROMIS PFUE CAT indicates its ability to differentiate both high and low functioning patients. All of these findings indicate that the PROMIS PFUE CAT is an adequate tool for the evaluation of patients with shoulder pain and should be used in these patients going forward. LEVEL OF EVIDENCE: Level II, diagnostic study.

Arthroscopic Management of SLAP Lesions With Concomitant Spinoglenoid Notch Ganglion Cysts: A Systematic Review Comparing Repair Alone to Repair With Decompression.

PURPOSE: To determine if cyst management is necessary in the setting of SLAP lesions with concomitant paralabral ganglion cysts. METHODS: We performed a systematic review according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, including all studies that met inclusion criteria from January 1975 to July 2015. We included patients with a SLAP II-VII lesion and a concomitant paralabral ganglion cyst who underwent arthroscopic labral repair with or without cyst decompression. Patients with follow-up of less than 3 months, a SLAP I lesion, or who underwent concomitant cuff repair were excluded. The Methodological Index for Non-randomized Studies (MINORS) scoring system was used to quantify the potential bias in each study. Outcome measures reported were provided in a table format and a subjective analysis was performed. RESULTS: Nineteen studies were included yielding a total of 160 patients: 66 patients treated with repair alone [R] and 94 patients with additional cyst decompression or excision [R+D]. The VAS, Rowe, and Constant scores were excellent and similar in both groups. The mean VAS was 0.6 in [R] and ranged between 0 and 2 in [R+D] (0.5, 0, 2, 0.2). The mean Rowe scores were 94 and 98 in [R] and 95 in [R+D]. The mean Constant scores were 97 in [R] and ranged between 87 and 98 in [R+D] (98, 87, 92, 94). In total, 5 of 90 patients were unable to return to work and 2 of 45 were unable to return to sport. All 15 patients who had follow-up electromyographies displayed resolution, and in the 115 patients with follow-up MRIs, 12 did not have complete resolution of the cyst. CONCLUSIONS: Despite the lack of high-quality evidence, the studies subjectively analyzed in this review suggest that both groups have excellent results. The results do not show any advantages from performing decompression. LEVEL OF EVIDENCE: Level IV, systematic review of Level II and Level IV studies.

Patient factors influencing outpatient satisfaction in patients presenting with shoulder pain.

BACKGROUND: Patient-based evaluation of health care has been gaining attention in the past 2 decades. The purpose of this study was to evaluate patient satisfaction in a shoulder outpatient clinic and determine which factors impact satisfaction levels. METHODS: Fifty-nine outpatients with shoulder complaints from December 2017 to January 2018 were included. Patient satisfaction was measured using the Clinician and Group Consumer Assessment of Healthcare Providers and Systems survey, and 2 methods of calculation were implemented: top-box and average scores. The impacts of age, gender, diagnosis, duration with the provider, Patient-Reported Outcomes Measurement Information System score, Pain Catastrophizing Scale score, pain visual analog scale (VAS) score, and function VAS score on patient satisfaction were analyzed. Patients were divided into more satisfied and less satisfied groups, and logistic regression analysis was performed to determine which factors affect patient satisfaction. RESULTS: The median total average and top-box scores were 95.2% and 90%, respectively. Similarly, in the analysis of all variables, average scores were always higher than top-box scores. The function VAS score and Patient-Reported Outcomes Measurement Information System score significantly influenced satisfaction. When patients were divided into more satisfied and less satisfied groups, the odds of having a less satisfied score among patients with a function VAS score of less than 5 was 5.5 times that of patients with a score of 5 or greater (odds ratio of 5.06 [95% confidence interval, 1.55-16.46] with P = .01 for univariate and adjusted odds ratio of 5.53 [95% confidence interval, 1.14-26.76] with P = .03 for multivariate). CONCLUSION: Despite being calculated from the same question set, using the average-score method for the Clinician and Group Consumer Assessment of Healthcare Providers and Systems survey generally yields higher scores than the top-box method. Among patients with shoulder pathology, function of the shoulder, as measured on a VAS, was the most significant factor influencing patient satisfaction in the outpatient setting.

Correlation of PROMIS Physical Function Upper Extremity Computer Adaptive Test with American Shoulder and Elbow Surgeons shoulder assessment form and Simple Shoulder Test in patients with shoulder arthritis.

BACKGROUND: The purpose of this study was to evaluate the Patient-Reported Outcomes Measurement Informative System Physical Function Upper Extremity Computer Adaptive Test (PROMIS PFUE CAT) measurement tool against the already validated American Shoulder and Elbow Surgeons (ASES) shoulder assessment form and the Simple Shoulder Test (SST) in patients with shoulder arthritis. METHODS: Fifty-two patients with the primary diagnosis of shoulder arthritis were asked to fill out the ASES, SST, and PROMIS PFUE CAT. The time for completion of each survey was measured to determine responder burden, and correlation between the 3 instruments was defined as excellent (>0.7), strong-moderate (0.61-0.7), moderate (0.31-0.6), and poor (0.2-0.3). RESULTS: The PROMIS PFUE CAT showed a strong-moderate correlation with the SST (r = 0.64; P < .001) and a moderate correlation with the ASES (r = 0.57; P < .001). The average times to complete the SST, ASES, and PROMIS PFUE CAT were determined to be 96.9 ± 25.1 seconds, 160.6 ± 51.5 seconds, and 62.6 ± 22.8 seconds, respectively. The time to complete the PROMIS PFUE CAT was significantly less than the time to complete the SST (P < .001) and the ASES (P < .001). CONCLUSION: In patients with shoulder arthritis, The PROMIS PFUE CAT demonstrated strong-moderate correlation with the SST and moderate correlation with the ASES. The time savings of the PROMIS PFUE CAT were small compared with the ASES and SST but demonstrate that moving forward, using the PROMIS PFUE CAT would not place any additional burden on the patient filling out the survey. These findings indicate that the PROMIS PFUE CAT is an appropriate measurement tool for patients with shoulder arthritis.

Risk factors for failing to achieve improvement after anatomic total shoulder arthroplasty for glenohumeral osteoarthritis.

BACKGROUND: Although anatomic total shoulder arthroplasty (TSA) successfully improves pain and function, not all patients improve clinically. This study was conducted to determine patient-related factors for failure to achieve improvement after primary TSA for osteoarthritis at 2 years postoperatively. METHODS: This prospective study reviewed an institutional shoulder registry for consecutive patients who underwent primary TSA for osteoarthritis from 2007 to 2013 with baseline and 2-year postoperative American Shoulder and Elbow Surgeons (ASES) Standardized Shoulder Assessment Form scores. A failed outcome was defined as (1) a failure to reach the ASES minimal clinically important difference of 16.1 points or (2) revision surgery within 2 years of the index procedure, or both. Univariate and multivariable analyses of clinical and demographic patient factors were performed using logistic regression. RESULTS: Of 459 arthroplasties that met inclusion criteria, 411 were deemed successful by the aforementioned criteria, and 48 (10.5%) failed to achieve a desirable outcome. Clinical risk factors associated with failure included previous surgery to the shoulder (P = .047), presence of a torn rotator cuff (P = .025), and presence of diabetes (P = .036), after adjusting for age, sex, race, and body mass index. A higher preoperative ASES score at baseline was associated with failure (P < .001). CONCLUSION: Previous shoulder surgery, a rotator cuff tear requiring repair during TSA, presence of diabetes, surgery on the nondominant arm, and a higher baseline ASES score were associated with a higher risk of failing to achieve improvement after anatomic TSA.
