Six-Week Radiographic Follow-up Does Not Change Management for Nonoperatively Treated Extraarticular Metacarpal Shaft Fractures.

BACKGROUND: Metacarpal fractures are common and account for over 30% of all hand fractures. Previous literature has shown similar outcomes between operative and nonoperative management of metacarpal shaft fractures. There is little information regarding the natural history of conservatively managed metacarpal shaft fractures and changes in management based on follow-up radiographs. METHODS: A retrospective chart review was performed on all patients who presented to a single institution with an extraarticular metacarpal shaft or base fracture between 2015 and 2019. RESULTS: Thirty-one patients with 37 metacarpal fractures were included for review: average age 41 years, male 48%, right hand dominant 91%, and average follow-up duration 7.3 weeks. At follow-up, a change of 2.4° in angulation (P = .0005) and a change in shortening of 0.1 mm (P = .0386) were noted over the 6-week time interval. No fractures had malrotation at presentation, and none developed malrotation during the follow-up period. CONCLUSIONS: Recent systematic reviews and meta-analysis have suggested that metacarpal fractures treated nonoperatively had similar outcomes to surgical fixation at 12 months of follow-up. We found that extraarticular metacarpal shaft fractures that do not meet operative indications at the initial visit should be expected to heal reliably with minimal change in angulation and shortening over time. The transition to removable brace or no brace at the 2-week follow-up is likely sufficient, and additional follow-up is not necessary and will reduce cost. LEVEL OF EVIDENCE: Level III.

Interscalene block vs. periarticular liposomal bupivacaine for pain control following reverse shoulder arthroplasty: a randomized trial.

BACKGROUND: Interscalene nerve blocks and local anesthetic infiltration are 2 methods commonly used in multimodal analgesia regimens for shoulder arthroplasty. Liposomal bupivacaine is a novel anesthetic that can be detected more than 24 hours following local administration. Studies comparing liposomal bupivacaine with conventional analgesic methods have found mixed results regarding pain and narcotic consumption, and there is little information available regarding patient satisfaction and the role of psychosocial variables. METHODS: This is a randomized study of 76 adult patients undergoing reverse shoulder arthroplasty who were assigned to receive a preoperative interscalene nerve block with ropivacaine (Block = 38) or an intraoperative periarticular injection of liposomal bupivacaine (Local = 38). The primary outcomes were narcotic consumption (MEq, morphine equivalents), visual analog scale (VAS) pain scores, and satisfaction (0-10). The secondary outcomes were the effect of patient group preference (Block vs. Local) and psychosocial variables (Pain Catastrophizing Scale, Brief Resilience Scale) on satisfaction. Length of stay, pain-related phone calls, pain-related readmissions, and the number of narcotic refills were tracked from the day of surgery through the first postoperative appointment, which was routinely 7-14 days following surgery. RESULTS: Intraoperative and day 0 narcotic consumption was lower in the Block group by 17.3 and 21.6 MEq (P < .001, P = .035) with no differences on day 1 or 2. There was no difference in VAS pain scores, length of stay, pain-related phone calls, pain-related readmissions, or the number of narcotic refills. Patient satisfaction was higher in the Block group (8.3 vs. 6.8, P = .017). Pain catastrophizing, resilience, and patient group preference did not have any significant relationship with patient satisfaction. CONCLUSION: Patients undergoing reverse shoulder arthroplasty have higher satisfaction with a conventional interscalene block compared to a periarticular injection of liposomal bupivacaine. There were no clinically important differences in narcotic consumption, VAS pain scores, length of stay, pain-related phone calls, pain-related readmissions, or the number of narcotic refills. The Pain Catastrophizing Scale, Brief Resilience Scale, and patient preferences did not have any relationship with patient satisfaction.

Patient-Reported Outcomes for Fractures of the Acetabulum: A Comparison Between Patient-Reported Outcomes Information System and Traditional Instruments.

INTRODUCTION: The objective of this study was to compare instruments from the Patient-Reported Outcomes Information System (PROMIS) with previously validated acetabulum fracture outcome instruments. METHODS: This study included adult patients presenting for routine follow-up at least 3 months after surgical treatment of an acetabulum fracture. Participants completed four different patient-reported outcomes in a randomized order: PROMIS Mobility, PROMIS Physical Function, Short Form 36 (SF-36), and Short Musculoskeletal Functional Assessment (SMFA). Primary outcomes were the correlations between instruments, floor/ceiling effects, and survey completion time. The effects of age, education, and race on survey completion time were also evaluated. RESULTS: Overall strong correlations were observed between PROMIS instruments and the SMFA/SF-36 (r = 0.73 to 0.86, P < 0.05) with weaker, more moderate correlations in those with >18 months of follow-up (r = 0.41 to 0.76, P < 0.05). No instruments demonstrated notable floor or ceiling effects. The PROMIS outcomes required less time to complete (PROMIS [56 to 59 seconds] than SF-36 [5 minutes 22 seconds] and SMFA [6 minutes 35 seconds]; P < 0.001). Older individuals required more time to complete the PROMIS PF (0.5 s/yr, P = 0.03), SF-36 (2.35 s/yr, P = 0.01), and SMFA (3.85 s/yr, P < 0.01). Level of education did not affect completion time; however, African Americans took significantly longer than Caucasians to complete the SMFA and SF-36 by 151 and 164 seconds (P < 0.01). CONCLUSION: This study supports that the PROMIS Mobility and Physical Function surveys are much more efficient instruments for evaluating patients with acetabulum fractures when compared with the SMFA and SF-36. Convergent validity of the PROMIS instruments was overall strong but weaker and more moderate in those with a long-term follow-up, and additional study is suggested for longer-term outcomes. Level of education did not influence survey completion time; however, it took markedly longer time for older individuals and African Americans to complete the SMFA and SF-36.

Pediatric and Adolescent Fractures of the Acetabulum Treated With ORIF: What Are Their Functional Outcomes?

OBJECTIVES: To evaluate the functional outcomes of pediatric and adolescent patients (<18 year old) who sustained acetabulum fractures that were treated with open reduction internal fixation (ORIF). DESIGN: Retrospective cohort. SETTING: Level 1 trauma center. PATIENTS: Thirty-four pediatric and adolescent patients underwent acetabulum fracture ORIF between 2001 and 2018. Of the operatively treated patients, 21 patients had sufficient follow-up (>6 months), one died after fixation secondary to other traumatic injuries, and 12 patients were lost to follow-up. INTERVENTION: Acetabulum fracture ORIF. MAIN OUTCOME MEASUREMENT: The SF-36 Health Survey and Short Musculoskeletal Functional Assessment (SMFA) were compared with population norms. The modified Merle d'Aubigné clinical hip score, Matta radiologic outcome, and postoperative complications were also documented. RESULTS: Functional outcome data were available at a mean of 5 years 2 months. Mean SF-36 scores were 44.8 and 50.1 for the physical component score and mental component scores, respectively, which did not differ significantly from US population norms (physical component score mean: 50, P = 0.061 and mental component score mean: 50, P = 0.973). Furthermore, the mean SMFA Bother Index score was 18.6, which is not significantly different from the population norm mean of 13.8 (P = 0.268). However, the function index mean was 31.9, which was significantly worse than the population norm mean of 12.7 (P = 0.001). Two patients with a delayed reduction (>6 hours) of an acetabulum fracture dislocation had poor outcomes related to the development of avascular necrosis and post-traumatic osteoarthritis. CONCLUSION: In this small cohort, 86% (18/21) of these patients had a favorable functional outcome with the exception of the SMFA Functional Index that was significantly less than population norms. Although long-term follow-up is needed, we advocate for operative management of pediatric and adolescent acetabulum fractures when adult displacement and instability criteria are present.

Reamer Irrigator Aspirator Versus Iliac Crest Bone Grafting and Proximal Tibial Curettage: Is There a Difference in Blood Loss and Transfusion Rates?

OBJECTIVES: To compare blood loss and transfusion rates among reamer irrigator aspirator (RIA), iliac crest bone graft (ICBG), and proximal tibial curettage (PTC) for autograft harvest. DESIGN: Retrospective comparative study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: The study included 139 adult patients treated between 2011 and 2018. INTERVENTIONS: Nonunion repair of the femur or tibia using either RIA (n = 64), ICBG (n = 59), or PTC (n = 16) for autograft. MAIN OUTCOME MEASUREMENTS: Estimated blood loss and transfusion rates. RESULTS: Patient demographics, surgical indications, and medical comorbidities that affect bleeding did not differ among the groups. Estimated blood loss (mL) was significantly higher in the RIA group [RIA: 388 ± 368 (50-2000), ICBG: 286 ± 344 (10-2000), PTC: 196 mL ± 219 (10-700), P < 0.01]. The transfusion rate was also significantly higher in the RIA group (RIA 14%, ICBG 0%, PTC 0%, P < 0.01). The amount of graft obtained was higher in the RIA group (RIA = 48.3 mL, ICBG = 31.0 mL, PTC = 18.8 mL, P < 0.01), and the operative time (hours) was longer in the RIA group (RIA = 2.8, ICBG = 2.6, PTC = 1.9, P = 0.04). CONCLUSION: Estimated blood loss and transfusion rates were significantly higher in patients undergoing RIA compared with those in patients undergoing ICBG and PTC; however, the incidence of transfusion after RIA (14%) was considerably lower than previous reports. These findings suggest that the risk of transfusion after RIA is present and clinically significant but lower than previously believed, and it is likely affected by the amount of graft obtained and complexity of the nonunion repair. The risk of transfusion should be discussed with patients and the choice of RIA carefully evaluated in patients who have anemia or risk factors of bleeding. LEVEL OF EVIDENCE: Therapeutic Level III.

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.

Hemiarthroplasty for Femoral Neck Fractures: Does Surgeon Subspecialty Affect Perioperative Outcomes?

OBJECTIVES: To determine if surgeon subspecialty training affects perioperative outcomes for displaced femoral neck fractures treated with hemiarthroplasty. DESIGN: Retrospective comparative study. SETTING: One health system with 2 hospitals (Level I and Level III trauma centers). PATIENT AND PARTICIPANTS: Patients who were treated with hemiarthroplasty for displaced femoral neck fractures between October 2012 and September 2017. OUTCOME MEASURES: Leg length discrepancy, femoral offset, estimated blood loss (EBL), incidence of blood transfusion, time to surgery, operative time, and length of stay. Data were analyzed based on the treating surgeon's subspecialty training [arthroplasty (A), trauma (T), other (O)]. Hierarchical regression was used to compare the groups and control for confounding variables. RESULTS: A total of 292 patients who received hemiarthroplasty for displaced femoral neck fractures were included (A = 158; T = 73; O = 61). Surgeon subspecialty had a statistically significant effect on operative time, with arthroplasty surgeons completing the procedure 9.6 minutes faster than trauma surgeons and 17.7 minutes faster than other surgeons (P < 0.01; ΔR = 0.03). Surgeon subspecialty did not significantly affect other outcomes, including leg length discrepancy (P = 0.26), femoral offset (P = 0.37), EBL (P = 0.10), incidence of transfusion (P = 0.67), time to surgery (P = 0.10), or length of stay (P = 0.67). CONCLUSIONS: This study demonstrates that arthroplasty-trained surgeons perform hemiarthroplasty slightly faster than other subspecialists, but subspecialty training does not affect other perioperative outcomes, including leg length discrepancy, femoral offset, EBL, transfusion rate, time to surgery, or length of stay. This suggests that hemiarthroplasty can be adequately performed by various subspecialists, and deferring treatment to an arthroplasty surgeon might not have a clinically significant benefit in the perioperative period. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Defining massive rotator cuff tears: a Delphi consensus study.

BACKGROUND: A standard definition for massive rotator cuff tears (MRCTs) has not been identified. The purpose of this study is to use the modified Delphi technique to determine a practical, consensus definition for MRCTs. METHODS: This study is based on responses from 20 experts who participated in 4 rounds of surveys to determine a consensus definition for MRCT. Consensus was achieved when at least 70% of survey responders rated an item at least a 4 on a 5-point scale. A set of core characteristics was drafted based on literature review and then refined to achieve a consensus MRCT definition. RESULTS: The following core characteristics reached consensus in the first round: tear size, number of tendons torn, and degree of medial retraction. Magnetic resonance imaging (MRI) and intraoperative findings reached consensus as the modalities of diagnosis. The second round determined that tear size should be measured as a relative value. An initial definition for MRCT was proposed in the third round: retraction of tendon(s) to the glenoid rim and/or a tear with ≥67% greater tuberosity exposure (65% approval). A modified definition was proposed that specified that degree of retraction should be measured in the coronal or axial plane and that the amount of greater tuberosity exposure should be measured in the sagittal plane (90% approval). CONCLUSIONS: This study determined with 90% agreement that MRCT should be defined as retraction of tendon(s) to the glenoid rim in either the coronal or axial plane and/or a tear with ≥67% of the greater tuberosity exposed measured in the sagittal plane. The measurement can be performed either with MRI or intraoperatively.

Terminal position of a tibial intramedullary nail: a computed tomography (CT) based study.

PURPOSE: The purpose of this study is to characterize the distal anatomic end-point of a tibial intramedullary nail placed using modern surgical techniques. The goal is to improve reduction of distal tibia fractures. METHODS: An intramedullary nail was placed in 14 skeletally mature legs. This included 8 patients with mid-shaft tibial fractures and 6 intact cadaveric legs. Each nail was a titanium cannulated tibial nail, size 10- or 11-mm. The nails were placed using a suprapatellar or transpatellar approach with an ideal starting point. All legs received post-nail insertion CT scans and fluoroscopy. The main outcome measure was the terminal location of the nail just proximal to the distal tibial physeal scar, as seen on axial CT and fluoroscopic views of the ankle (mortise and lateral). The end-point was measured as the (1) ratio of medial-lateral tibial width (ML ratio) and (2) ratio of anterior-posterior tibial width (AP ratio). Two-tailed Welch's t tests were used to compare the actual, observed position of the nail to the hypothesized center-center position (H0 = ML and AP ratio of 0.5). RESULTS: All enrolled patients (n = 8) and cadaveric legs were included (n = 6). On axial CT, the average distance from the medial tibial cortex to the nail center as a ratio of medial-lateral tibial width was 0.63, 95% CI 0.60-0.67, p < 0.001 (Patient = 0.60, 95% CI 0.55-0.64, p = 0.001) (Cadaver = 0.68, 95% CI 0.64-0.73, p < 0.001). On fluoroscopic mortise views, the distance from the medial cortex to the nail center as ratio of medial-lateral tibial width was 0.64, 95% CI 0.60-0.67, p < 0.001 (Patient = 0.61, 95% CI 0.56-0.65, p < 0.001) (Cadaver = 0.67, 95% CI 0.63-0.72, p < 0.001). The AP ratio was not significantly different from 0.5 on either axial CT or fluoroscopic mortise views (p > 0.05). CONCLUSION: The distal end-point of a tibial intramedullary nail is lateral (ML plane) and center (AP plane) in both cadaveric legs and patients with midshaft tibia fractures. These results suggest that the treatment of distal tibia fractures with intramedullary nails may be improved by positioning the nail slightly lateral in the distal segment. LEVEL OF EVIDENCE: Diagnostic level I.

Quantifying the Impact of Patient-Specific Factors and Disease Severity on Clinical Decision Making in Cuff Tear Arthropathy: A Case-Based Survey.

BACKGROUND: Rotator cuff tears are a common cause of disability. Some patients with massive and irreparable tears can develop cuff tear arthropathy (CTA), which makes management more challenging. QUESTIONS/PURPOSES: We sought to examine how orthopedists determine treatment for patients with CTA. Specifically, we investigated (1) the effect of patient age, symptoms, activity level, range of motion, and radiographic findings on the decision making of shoulder specialists and (2) the observer reliability of the Seebauer and Hamada grading systems. METHODS: Five shoulder surgeons were each sent 108 simulated patient cases. Each simulated patient had a different combination of factors, including patient age, symptoms, activity level, range of motion, and radiographs. Responders graded the radiographs and chose a treatment (non-operative, arthroscopic, hemiarthroplasty, or reverse total shoulder arthroplasty). Spearman's correlations and χ 2 tests were used to assess the relationship between factors and treatments. Sub-analysis was performed on surgical cases. An intra-class correlation (ICC) was used to assess observer agreement. RESULTS: The significant Spearman's correlations were symptoms (0.45), Hamada grade (0.38), patient age (0.34), and Seebauer type (0.29). In sub-analysis of operative cases, the significant correlations were Hamada grade (0.56), patient age (0.51), Seebauer type (0.46), activity level (-0.13). The χ 2 analysis was significant for all factors except activity level. The inter- and intraobserver reliabilities were, respectively, Seebauer type (0.59 and 0.63) and Hamada grade (0.58 and 0.65). Interobserver reliability for patient management was 0.44. CONCLUSION: When evaluating CTA, patient symptoms, radiographic grade, and patient age are the factors most strongly associated with the decision making of shoulder specialists. Additionally, the Seebauer and Hamada classifications had similar reliability and clinical utility. However, there was only fair agreement regarding treatment, which indicates that CTA management remains controversial.

Narcotic Use and Resiliency Scores Do Not Predict Changes in Sleep Quality 6 Months After Arthroscopic Rotator Cuff Repair.

BACKGROUND: Patients with rotator cuff disease commonly complain of difficulty sleeping. Arthroscopic repair has been associated with improved sleep quality in many patients with rotator cuff tears; however, some individuals continue to suffer from sleep disturbance postoperatively. PURPOSE: To determine whether changes in sleep quality following rotator cuff repair are predicted by a patient's narcotic use or ability to cope with stress (resilience). STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 48 patients undergoing arthroscopic rotator cuff repair were prospectively enrolled and completed the Connor-Davidson Resilience Scale (CD-RISC) preoperatively. The Pittsburgh Sleep Quality Index (PSQI) was administered preoperatively and at multiple intervals postoperatively for 6 months. Narcotic utilization was determined via a legal prescriber database. Pre- and postoperative sleep scores were compared using paired t tests and the McNemar test. Linear regression was used to determine whether narcotic use or CD-RISC score predicted changes in sleep quality. RESULTS: An increased number of patients experienced good sleep at 6 months postoperatively (P < .01). Mean ± SD nocturnal pain frequency improved from 2.5 ± 1.0 at baseline to 0.9 ± 1.1 at 6 months. CD-RISC score had a positive predictive value on changes in PSQI score (R 2 = 0.09, P = .028) and nocturnal pain frequency (R 2 = 0.08, P = .041) at 2 weeks. Narcotic use did not significantly predict changes in PSQI score or nocturnal pain frequency (P > .05). CONCLUSION: Most patients with rotator cuff disease will experience improvement in sleep quality following arthroscopic repair. Patients demonstrated notable improvements in nocturnal pain frequency as soon as 6 weeks following surgery. CD-RISC resiliency scores had a significant positive predictive value on changes in sleep quality and nocturnal pain frequency at 2 weeks. Narcotic use was not associated with change in sleep quality.

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 After Coracoid Transfer in Athletes With Anterior Shoulder Instability: A Systematic Review.

CONTEXT: Recurrent shoulder instability in young athletes can lead to a spectrum of soft tissue and bony lesions that can be bothersome and/or disabling. Coracoid transfer is a treatment option for athletes with recurrent instability. OBJECTIVE: To report the rate of return to sport for athletes after coracoid transfer. DATA SOURCES: An electronic search of the literature was performed using the PubMed (MEDLINE) and Cochrane Databases (1966-2018). STUDY SELECTION: Studies were included if they evaluated return to sport after treatment with coracoid transfer at a minimum 1-year follow-up. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: Data were extracted by 2 authors and included study design, level of evidence, patient demographics (number, age, sex), procedure performed, duration of clinical follow-up, rate of return to sport, patient-reported outcome measures, reoperations, and complications. RESULTS: Fourteen studies met the inclusion criteria. The rate of return to sport at any level ranged from 80% to 100% in all but 1 study (38%), and the rate of return to the previous level of play ranged from 56% to 95% in all but 1 study (16%). Patients returned to sport at an average of 3.2 to 8.1 months. The average patient-reported outcome scores ranged from 78% to 94% (Rowe), 223.6 to 534.3 (Western Ontario Shoulder Instability Index), and 75% to 90% (subjective shoulder value). The rate of postoperative dislocation ranged from 0% to 14%, and the reoperation rate ranged from 1.4% to 13%. CONCLUSION: There was a high early rate of return to sport in patients who underwent coracoid transfer for anterior shoulder instability, although patients did not reliably return to the same level of play. The procedure had very favorable outcomes for treatment of instability, with low rates of recurrent dislocation and reoperation.

Evaluating Glenohumeral Osteoarthritis: The Relative Impact of Patient Age, Activity Level, Symptoms, and Kellgren-Lawrence Grade on Treatment.

BACKGROUND: It is not always clear how to treat glenohumeral osteoarthritis, particularly in young patients. The goals of this study were to 1) quantify how patient age, activity level, symptoms, and radiographic findings impact the decision-making of shoulder specialists and 2) evaluate the observer reliability of the Kellgren-Lawrence (KL) grading system for primary osteoarthritis of the shoulder. METHODS: Twenty-six shoulder surgeons were each sent 54 simulated patient cases. Each patient had a different combination of age, symptoms, activity level, and radiographs. Responders graded the radiographs and chose a treatment (non-operative, arthroscopy, hemiarthroplasty, or total shoulder arthroplasty). Spearman correlations and chi square tests were used to assess the relationship between factors and treatments. Sub-analysis was performed on surgical cases. An intra-class correlation (ICC) was used to assess observer agreement. RESULTS: The significant correlations (P<0.01) were: symptoms [0.46], KL grade [0.44], and age [0.11]. In the sub-analysis of operative cases, the significant correlations were: KL grade [0.64], age [0.39], and activity level [-0.10]. The chi square analysis was significant (P<0.01) for all factors, but the practical significance of activity level was minimal. The ICCs were [inter](intra): KL [0.79] (0.84), patient management [0.54]. CONCLUSION: When evaluating glenohumeral osteoarthritis, patient symptoms and KL grade are the factors most strongly associated with treatment. In operative cases, the factors most strongly associated with the choice of operation were the patient's KL grade and age. Additionally, the KL classification demonstrated excellent observer reliability. However, there was only moderate agreement among shoulder specialists regarding treatment, indicating that this remains a controversial topic.

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.

Factors Predictive of Blocking Screw Placement in Retrograde Nailing of Distal Femur Fractures.

OBJECTIVES: (1) Identify factors that predict blocking screw placement in the treatment of a distal femur fracture with retrograde nail fixation and (2) determine whether acceptable alignment and stability were achieved in fractures that received blocking screws. DESIGN: Retrospective Comparative Study. SETTING: Level I Trauma Center. PATIENTS/PARTICIPANTS: Between 2011 and 2017, we identified 84 patients with distal third femur fractures treated with a retrograde femoral nail. Data were analyzed according to those who did (BLOCK, n = 30) and did not (NO BLOCK, n = 54) receive blocking screws. Patients in both groups were treated by orthopaedic trauma surgeons; postoperative weight-bearing radiographs were obtained of every patient. INTERVENTION: Fixation using a retrograde femoral nail with or without blocking screws. Blocking screws were placed at the discretion of the treating surgeon to reduce malaligned fractures or improve stability. MAIN OUTCOME MEASUREMENTS: (1) Demographics, radiographic apparent bone gap (RABG), space available for the nail (SAFN), and distal segment length [as a ratio of bicondylar width (BCW)]; and (2) post-operative alignment and stability (change in alignment over time). RESULTS: Patients treated with blocking screws had a higher body mass index (BMI) (BLOCK: 29.0, NO BLOCK 25.7, P = 0.03). In addition, the BLOCK group had larger RABGs (BLOCK: 8.2 mm, NO BLOCK: 3.6 mm, P = 0.02), more SAFN (BLOCK: 51.4 mm, NO BLOCK: 39.8 mm, P = 0.02), and shorter distal segments (BLOCK: 1.7 × BCW, NO BLOCK: 2.0 × BCW, P = 0.01). In a multivariable logistic regression, the combination of these factors was significantly predictive of blocking screw placement with a large effect size (R = 0.36, P < 0.01). A distal segment length ≤ ×2 BCW was 77% sensitive for blocking screw placement, and a BMI ≥25 kg/m was 70% sensitive. Negative predictive values for blocking screw placement were distal segment length > ×2 BCW (79%), BMI <25 kg/m (77%), RABG <4 mm (76%), and SAFN <50 mm (71%). Patients that received blocking screws had acceptable postoperative alignment and stability, similar to fractures that did not receive blocking screws (P > 0.05). CONCLUSIONS: This retrospective study of distal femur fractures treated with retrograde nails identified several factors that can be used to predict when blocking screw placement may be useful for increasing stability and maintaining alignment in distal third femur fractures treated with retrograde IM nails. Patients treated with blocking screws had a higher BMI, greater cortical bone loss, more SAFN, and shorter distal segments. There was no difference in postoperative alignment or stability between the 2 groups. LEVEL OF EVIDENCE: Prognostic Level III.

Knee Sepsis after Suprapatellar Nailing of an Open Tibia Fracture: Treatment with Acute Deformity and External Fixation.

CASE: A 31-year-old male was involved in a dirt bike accident and sustained an isolated type II open mid-distal tibia fracture. The patient underwent suprapatellar intramedullary nailing and subsequently developed knee sepsis. CONCLUSION: This patient was managed with irrigation and debridements of the knee, fracture site, and intramedullary canal. A resultant soft-tissue defect over the fracture site obviated primary closure. Creation of an acute deformity stabilized by a Taylor spatial frame allowed primary wound closure. After soft tissue healing occurred, the frame was used to correct the intentional deformity and maintain reduction until full healing occurred.

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.

Treatments of Choice for Isolated, Full-Thickness Tears of the Posterior Cruciate Ligament: A Nationwide Survey of Orthopaedic Surgeons.

The ideal treatment for isolated, full-thickness tears of the posterior cruciate ligament (PCL) is uncertain. The purpose of this study was to determine how the majority of orthopaedic surgeons treat isolated, full-thickness tears of the PCL. In July 2017, a 17-question multiple-choice survey regarding the treatment of isolated, full-thickness tears of the PCL was emailed to 3,500 orthopaedic sports medicine surgeons with membership in the American Orthopaedic Society for Sports Medicine. Responders answered multiple-choice questions related to indications, technique, graft choice, bracing, and weight-bearing status following reconstruction. Answer choices were then analyzed against surgeon-specific variables. The survey was completed by 663 orthopaedic surgeons. Of the responders, 93% were fellowship trained in sports medicine with an average practice duration of 13 years. The total number of PCLs reconstructed per surgeon was low, 11.6. On average, surgeons estimate they reconstruct the PCL in only 22% of patients with full-thickness tears. The two most common surgical indications were functional limitations and failure of physical therapy. The reconstruction of choice involves a transtibial approach (63%) with a single bundle (87%) allograft (83%) of the Achilles tendon (51%). The postoperative brace is typically locked in extension (66%), and weight-bearing is delayed for 3.8 weeks. Of the surgeons with the fewest years of experience, 39% use all-inside, 89% use allograft, and 24% use dynamic bracing. Compared with surgeons with the most years of experience, only 16% use all-inside (p < 0.01), 57% use allograft (p < 0.01), and 11% use dynamic bracing (p = 0.01). Isolated, full-thickness tears of the PCL are rare injuries that are infrequently reconstructed. The most common indications for reconstruction are functional limitations and failure of conservative management. Most surgeons' treatment of choice for reconstruction involves a transtibial approach with a single bundle Achilles allograft and a postoperative brace locked in extension. On average, weight-bearing is prolonged for 3.8 weeks. The all-inside technique, allograft, and dynamic bracing are becoming more popular.
