Return to Sport Following Distal Triceps Repair.

PURPOSE: The purpose of this investigation was to examine the timeline of return-to-sport following distal triceps repair; evaluate the degree of participation and function upon returning to sport; and identify risk factors for failure to return to sport. METHODS: Patients who underwent distal triceps repair with a minimum of 1 year of follow-up were retrospectively reviewed. Patients completed a subjective sports questionnaire and were scored on a visual analog scale for pain; the Mayo Elbow Performance Index; the Quick Disabilities of the Arm, Shoulder, and Hand; and the Single Assessment Numerical Evaluation. RESULTS: Out of 113 eligible patients who had a distal triceps repair, 81 patients (71.7%) were contacted. Sixty-eight patients (84.0%) who participated in sports prior to surgery were included at 6.0 ± 4.0 years after surgery, and the average age was 46.6 ± 11.5 years. Sixty-one patients (89.7%) resumed playing at least 1 sport by 5.9 ± 4.4 months following distal triceps repair. However, 18 patients (29.5%) returned to a lower level of activity intensity. The average postoperative Quick Disabilities of the Arm, Shoulder, and Hand; Mayo Elbow Performance; visual analog scale for pain; and Single Assessment Numerical Evaluation scores were 8.2 ± 14.0, 89.5 ± 13.4, 2.0 ± 1.7, and 82.2 ± 24.3, respectively. No patients underwent revision surgery at the time of final follow-up. CONCLUSIONS: Distal triceps repair enables 89.7% of patients to return to sport by 5.9 ± 4.4 months following surgery. However, 29.5% of patients were unable to return to their preinjury level of activity. It is imperative that patients are appropriately educated to manage postoperative expectations regarding sport participation following distal triceps repair. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

High Rate of Return to Work by 3 Months Following Latarjet for Anterior Shoulder Instability.

PURPOSE: To evaluate the rate and duration of return to work in patients undergoing Latarjet for failed soft-tissue stabilization or glenoid bone loss. METHODS: Consecutive patients undergoing Latarjet from 2005 to 2015 at our institution were retrospectively reviewed at a minimum of 2 years postoperatively. Patients completed a standardized and validated work questionnaire, Western Ontario Shoulder Instability Index Survey, and a satisfaction survey. RESULTS: Of 89 eligible patients who had Latarjet, 67 patients (75.3%) responded to the questionnaire, of whom 51 patients (76.1%) were employed within 3 years before surgery (mean age: 29.9 ± 11.8 years; mean follow-up: 54.6 ± 11.9 months) and had an average glenoid bone loss of 14.5 ± 6.1%. Fifty patients (98.0%) returned to work by 2.7 ± 3.0 months postoperatively; 45 patients (88.2%) patients returned to the same level of occupational intensity. Those who held sedentary, light, moderate, or heavy intensity occupations returned to their previous occupation at a rate of 100.0%, 93.3%, 90.0%, and 66.7% (P = .2) at a duration of 1.2 ± 1.6 months, 1.8 ± 1.9 months, 3.1 ± 3.5 months, and 6.5 ± 4.1 months (P = .001), respectively. The average postoperative Western Ontario Shoulder Instability Index score was 70.9 ± 34.2. Fifty patients (98.0%) noted at least "a little improvement" in their quality of life following surgery, with 35 patients (68.6%) noting great improvement. Furthermore, 49 patients (96.1%) reported being satisfied with their procedure, with 25 patients (49.0%) reporting being very satisfied. Four patients (7.8%) returned to the operating room, with 1 patient (2.0%) requiring arthroscopic shoulder stabilization. CONCLUSIONS: Approximately 98% of patients who underwent Latarjet returned to work by 2.7 ± 3.0 months postoperatively. Patients with greater-intensity occupations had a longer duration of absence before returning to their preoperative level of occupational intensity. Information regarding return to work is imperative in preoperative patient consultation to manage expectations. LEVEL OF EVIDENCE: IV, case series.

Return to sport following Latarjet glenoid reconstruction for anterior shoulder instability.

BACKGROUND: Latarjet coracoid transfer reconstruction is the gold standard for the treatment of recurrent shoulder instability with anterior-inferior glenoid bone loss, and return to sport is often a primary outcome of interest in this patient population. The purpose of this study was to determine the rate of return to sport in patients undergoing the Latarjet procedure and variables that are associated with a higher likelihood of a successful return to sport. METHODS: A prospectively maintained institutional registry was retrospectively queried between August 2012 and August 2016 for all patients who underwent the Latarjet procedure. Patients were contacted electronically and via telephone to administer a previously validated and standardized return-to-sport survey. Patients self-reported return to sport, varying sports participation, recurrence of instability, and time to return to sport. Multivariate analysis was performed to determine variables associated with each outcome. RESULTS: Of 83 patients, 66 (75.3%) were available for final follow-up, of whom 60 participated in sports prior to surgery and were eligible for inclusion. The average follow-up period was 53.8 ± 11.8 months. The average age at surgery was 26.7 ± 11.3 years, and the average body mass index was 26.2 ± 4.0 kg/m2. There were 54 patients (90%) who were able to return to sport at an average of 8.6 ± 4.1 months following surgery. In total, 36 patients (60%) were able to return to sport at the same level or a better level of intensity, 19 of 28 patients (67.9%) were able to return to throwing sports without difficulty, and 31 of 60 patients (51.7%) reported that their shoulder was a hindrance to some activity. An increased likelihood of returning to sport was associated with increased body mass index (P = .016), male sex (P = .028), and decreased humeral bone loss volume (P = .034). An increased likelihood of returning to sport at the same level or a better level of intensity was associated with reduced humeral bone loss volume (P = .026). Recurrent instability was associated with humeral bone loss (P = .038). CONCLUSION: Although a large majority of patients were able to return to sport following the Latarjet procedure, some patients experienced limitation with throwing and return to sport at the preinjury level. Greater humeral bone loss was associated with inferior outcomes. These findings should be discussed with patients in the preoperative setting to manage expectations appropriately.

Return to sport and weightlifting analysis following distal biceps tendon repair.

BACKGROUND: Rupture of the distal biceps tendon is an increasingly frequent injury sustained predominantly by middle-aged men. Despite the prevalence of sport in this age group, little is known regarding return to sport outcomes following surgery. METHODS: Patients undergoing distal biceps tendon repair (DBR) between January 2015 and January 2017 were contacted electronically via e-mail and via telephone to administer a previously validated and standard return to sport survey. Patients self-reported preinjury and current level of sport and activity as well as preinjury and current level of select weightlifts. RESULTS: A total of 77 of 124 patients were available for follow-up (62.1%). Of these patients, 61 endorsed preoperative sport and were included for analysis. Average follow-up was 38.7 ± 6.7 months. The mean age at surgery was 47.5 ± 8.8 years, and the mean body mass index was 30.3 ± 5.1. The dominant side was affected in 25 of 61 cases. Of the 61 included patients, 57 (93.4%) were able to return to sport at any level (lower, same, or higher intensity than preinjury activity level). Forty of the patients (65.6%) were able to return to sport at same or higher intensity. Mean time to return to sport was 6.0 ± 2.8 months. Days from injury to surgery (odds ratio [OR] 0.999, 95% confidence interval [CI] 0.998-0.999), suture anchor fixation in comparison to suture button (OR 0.602, 95% CI 0.427-0.850), and dominant-side surgery (OR 0.749, 95% CI 0.582-0.963) were associated with a decreased likelihood to return to sport at same or higher level of duty. Single-sided incision in comparison to double (OR 5.209, 95% CI 1.239-20.903) and dominant-side surgery (OR 6.370, 95% CI 1.639-24.762) were associated with increased duration to return to sport. CONCLUSION: Distal biceps tendon rupture is a significant injury; however, patients can expect high levels of return to sport following DBR with some residual impairment compared with baseline. It is important to counsel patients on their expectations while taking into account the results of this study: that there will be a small but appreciable decrease in strength compared with preinjury levels.

Return to work following distal triceps repair.

PURPOSE: The purpose of this study was to evaluate the rate and duration of return to work in patients undergoing distal triceps repair (DTR). METHODS: Consecutive patients undergoing DTR from 2009 to 2017 at our institution were retrospectively reviewed at a minimum of 1 year postoperatively. Patients completed a standardized and validated work questionnaire; a visual analog scale for pain; the Mayo Elbow Performance Score; the short version of the Disabilities of the Arm, Shoulder and Hand questionnaire; and a satisfaction survey. RESULTS: Of 113 eligible patients who underwent DTR, 81 (71.7%) were contacted. Of these patients, 74 (91.4%) were employed within 3 years prior to surgery (mean age, 46.0 ± 10.7 years; mean follow-up, 5.9 ± 3.9 years). Sixty-nine patients (93.2%) returned to work by 2.2 ± 3.2 months postoperatively. Sixty-six patients (89.2%) were able to return to the same level of occupational intensity. Patients who held sedentary-, light-, medium-, and high-intensity occupations were able to return to work at a rate of 100.0%, 100.0%, 80.0%, and 76.9%, respectively, by 0.3 ± 0.5 months, 1.8 ± 1.5 months, 2.5 ± 3.6 months, and 4.8 ± 3.9 months, respectively, postoperatively. Of the workers' compensation patients, 15 (75%) returned to work by 6.5 ± 4.3 months postoperatively, whereas 100% of non-workers' compensation patients returned to work by 1.1 ± 1.6 months (P < .001). Seventy-one patients (95.9%) were at least somewhat satisfied, with 50 patients (67.6%) reporting excellent satisfaction. Seventy-two patients (97.3%) would undergo the operation again if presented the opportunity. A single patient (1.4%) required revision DTR. CONCLUSIONS: Approximately 93% of patients who underwent DTR returned to work by 2.2 ± 3.2 months postoperatively. Patients with higher-intensity occupations had an equivalent rate of return to work but took longer to return to their preoperative level of occupational intensity. Information regarding return to work is imperative in preoperative patient consultation to manage expectations.

Return to Sport and Patient Satisfaction After Meniscal Allograft Transplantation.

PURPOSE: To investigate patient return to sport and satisfaction after meniscal allograft transplantation (MAT). METHODS: Patients undergoing MAT using a bone bridge technique between 2013 and 2015 with minimum 2-year follow-up were retrospectively reviewed. They completed a survey regarding return to sport, satisfaction, and subsequent surgery in addition to patient-reported outcome measures. RESULTS: Of 117 patients, 87 (74.4%) were available at an average follow-up of 3.64 years (range, 2.01-5.13 years). The mean age at the time of surgery was 28.99 ± 8.26 years. Lateral MAT was performed in 44 cases (50.6%); medial MAT, 42 (48.3%); and combined medial and lateral MAT, 1 (1.1%). Concomitant procedures were performed in 72 patients (82.7%) including cartilage restoration (n = 65, 74.7%), realignment (n = 9, 10.3%), and anterior cruciate ligament reconstruction (n = 9, 10.3%). Patients experienced significant improvement in the Lysholm score (P < .001), International Knee Documentation Committee score (P < .001), Knee Injury and Osteoarthritis Outcome Score (KOOS)-Quality of Life (P < .001), KOOS-Activities of Daily Living (ADL) (P < .001), KOOS-Pain (P < .001), KOOS-Sports (P = .001), KOOS-Symptoms (P = .003), Short Form 12 physical score (P < .001), and Veterans Rand-12 physical score (P < .001). Reoperation was performed in 26 patients (29.9%); failure occurred in 12 patients (13.8%; total knee arthroplasty in 1, unicompartmental arthroplasty in 2, and total meniscectomy in 9). Overall, 77.0% of patients were satisfied with their outcome. Prior to MAT, 82 patients (94.3%) participated in sporting activities; 62 patients (75.6%) returned to at least one sport at 12.58 ± 6.20 months postoperatively, with 30 (48.4%) reaching their preoperative level of intensity and 72 (87.8%) discontinuing at least one of their preoperative sports. The most common reasons for sports discontinuation postoperatively were prevention of further damage (73.6%), pain with activity (51.4%), fear of further injury (48.6%), surgeon recommendation (33.3%), and swelling with activity (30.6%). Patients were satisfied with their sports participation at a rate of 62.1%. CONCLUSIONS: In a complex patient population undergoing arthroscopic MAT, 75.6% of patients were able to return to at least one sport at an average of 12.58 ± 6.20 months postoperatively. The level of sport declined, with 93.5% of patients restricting involvement to recreational sports after MAT and 48.4% returning to their preoperative level of activity intensity. In addition, 87.8% of patients reported discontinuing a sport in which they had participated preoperatively. The most common reasons for decreasing level of sport were prevention of further damage, pain or swelling with sports, and fear of further injury. The reoperation rate after MAT was 29.9%. Most patients were satisfied with the outcome of surgery, with 77.0% satisfied in general and 62.1% satisfied with their ability to play sports. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Return to Sport and Outcomes After Concomitant Lateral Meniscal Allograft Transplant and Distal Femoral Varus Osteotomy.

PURPOSE: To evaluate the time and rate of return to sport (RTS), as well as outcomes, in young and active patients receiving concomitant lateral meniscal allograft transplantation (MAT) and distal femoral varus osteotomy (DFVO) for lateral meniscal deficiency and valgus malalignment. METHODS: This was a retrospective study of consecutive patients who underwent concomitant MAT and DFVO by a single surgeon. The exclusion criteria were any concomitant procedures other than cartilage restoration procedures for focal full-thickness cartilage defects of the lateral femoral condyle and less than 2 years of follow-up. At final follow-up, patients were asked to complete a subjective sports questionnaire, the Marx Activity Rating Scale, a visual analog scale (VAS), the Single Assessment Numeric Evaluation, and a satisfaction questionnaire. Changes in patient-reported outcome measures were assessed using nonparametric statistical testing. RESULTS: A total of 21 patients met the inclusion criteria, of whom 17 were included for analysis at an average follow-up of 7.5 years (range, 2.2-13.3 years). The average age at the time of surgery was 23.3 years (range, 16.9-36.2 years), and 76.5% of patients were female patients. The average VAS score decreased from 5.7 preoperatively to 2.6 postoperatively (P = .02). Of the 15 patients who participated in sports within 3 years prior to their surgical procedure, 14 (82.4%) returned to 1 or more sports at an average of 16.9 months (range, 6-36 months); however, only 46.7% were able to return to their preinjury level of participation or higher. Furthermore, 88.2% of patients reported being satisfied with their sport-related outcomes. Direct rates of sport-specific return were as follows: weightlifting, 100%; skiing, 100%; running, 66.7%; and basketball, 50%. CONCLUSIONS: In our study population, concomitant MAT and DFVO afforded a high rate of RTS at an average of 16.9 months postoperatively, as well as a significant decrease in VAS pain scores. These findings are essential to note when counseling patients receiving these procedures who wish to resume sports and physical activities so that they may expect an extensive recovery process before they can RTS. LEVEL OF EVIDENCE: Level IV, case series.

Return to Work Following High Tibial Osteotomy With Concomitant Osteochondral Allograft Transplantation.

PURPOSE: To assess the timeline of return to work (RTW) following opening-wedge high tibial osteotomy (HTO) with concomitant osteochondral allograft transplantation (OCA) of the medial femoral condyle. METHODS: Consecutive patients undergoing HTO + OCA due to focal chondral deficiency and varus deformity were retrospectively identified and reviewed at a minimum of 2 years following surgery. Patients completed a subjective work questionnaire, a visual analog scale for pain, Single Assessment Numerical Evaluation, and a satisfaction questionnaire. RESULTS: Twenty-eight patients (average age: 36.0 ± 7.9 years) were included at 6.7 ± 4.1 years postoperatively. Twenty-six patients were employed before surgery and 25 patients (96.2%) returned to work following HTO + OCA. However, only 88.5% of patients were able to return to the same level of occupational intensity by 3.5 ± 2.9 months postoperatively. The rate of RTW to the same occupational intensity for sedentary, light, medium, and heavy intensity occupations was 100%, 100%, 88.9%, and 80% (P = .8), whereas the duration of RTW was 9.0 ± 7.1 months, 1.7 ± 1.4 months, 2.7 ± 0.9 months, and 4.2 ± 1.9 months (P = .006), respectively. Two patients (7.7%) underwent knee replacement by 5.3 ± 3.1 years postoperatively due to progression of osteoarthritis in the medial compartment. CONCLUSIONS: In patients with focal chondral deficiency and varus deformity, HTO + OCA provides a high rate of RTW (96.2%) by 3.5 ± 2.9 months postoperatively. However, patients with greater-intensity occupations may take longer to return to work than those with less physically demanding occupations. LEVEL OF EVIDENCE: IV, Retrospective Case Series.

Arthroscopic Suprapectoral and Open Subpectoral Biceps Tenodeses Produce Similar Outcomes: A Randomized Prospective Analysis.

PURPOSE: To directly compare subjective and objective outcomes of arthroscopic suprapectoral biceps tenodesis (ASPBT) below the bicipital groove and open subpectoral biceps tenodesis (OSPBT) performed with interference screw fixation. METHODS: A total of 77 patients indicated for biceps tenodesis who met the inclusion and exclusion criteria were randomized into the ASPBT and OSPBT groups. All tenodesis procedures implemented PEEK (polyether ether ketone) interference screws. Patients underwent a clinical examination that included range of motion and strength assessment at 3, 6, and 12 months postoperatively. Patients completed the American Shoulder and Elbow Surgeons (ASES) shoulder score, Single Assessment Numeric Evaluation score, and Constant score preoperatively and at 6 and 12 months postoperatively. RESULTS: Seventy-five patients were analyzed with a mean age of 50.3 ± 10.4 years and a mean body mass index of 28.9 ± 6.3. All patients had arthroscopic evidence of biceps pathology and underwent either an ASPBT (n = 37) or OSPBT (n = 38). The surgical time was significantly greater for ASPBT than for OSPBT (16.9 ± 8.4 minutes vs 9.8 ± 3.1 minutes, P < .001). One patient underwent conversion from the ASPBT group to the OSPBT group because of shearing of a severely attenuated tendon preventing an ASPBT. No significant difference (P > .05) was found in strength or anterior shoulder pain at 3 months, 6 months, and 1 year, and no significant difference (P > .05) was found in clinical outcome scores (ASES, Constant subjective, and Single Assessment Numeric Evaluation) between the 2 groups at 6 months and 1 year. The improvement in the ASES score exceeded the minimal clinically important difference (12 points) in both groups. CONCLUSIONS: No differences in patient-reported outcome measures, functional outcomes, or complication rates were found after ASPBT compared with OSPBT. However, the results of this investigation must be interpreted with caution because this study may be underpowered to detect statistical differences. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

Anatomic total shoulder arthroplasty with an inlay glenoid component: clinical outcomes and return to activity.

BACKGROUND: Biomechanical studies show that inlay glenoid components in total shoulder arthroplasty (TSA) can reduce edge loading and opposite-edge lift-off forces with humeral translation compared with onlay glenoids. However, clinical data for these implants are lacking. We report clinical outcomes and return to activities after anatomic TSA with an inlay glenoid component and a stemless ovoid humeral head in an active, young patient population. METHODS: A retrospective review of TSA with an inlay glenoid component and an ovoid humeral head component was performed for 27 shoulders. Patients were evaluated with patient-reported outcome measures, range of motion, and radiographs. Return to occupational and sporting activity, complications, and reoperations were analyzed. RESULTS: A total of 27 shoulders were available for minimum 2-year follow-up. Age averaged 52.1 years, and 92.6% of shoulders were in male patients. The preoperative Walch grade was A1 or A2 in 15 shoulders (55%), B1 in 8 (30%), and B2 in 4 (15%). Patients showed significant improvements in patient-reported outcome measures, active forward flexion, and external rotation (P < .001) with no reoperations. At an average of 3.7 months, the rate of return to work was 92.6%, with 76.0% of those patients returning to their preoperative occupational demand level. At an average of 9.1 months, 75% of patients who responded to our custom survey returned to sport, with 50% achieving the same level or a higher level of sporting activity. Annual postoperative radiographs revealed no inlay component loosening. CONCLUSION: Anatomic TSA with an inlay glenoid coupled with a stemless ovoid humeral head in an active population resulted in improved clinical outcomes, no reoperations or radiographic loosening, and a high rate of return to activity at shorter-term follow-up.

What Associations Exist Between Comorbidity Indices and Postoperative Adverse Events After Total Shoulder Arthroplasty?

BACKGROUND: Comorbidity indices like the modified Charlson Comorbidity Index (mCCI) and the modified Frailty Index (mFI) are commonly reported in large database outcomes research. It is unclear if they provide greater association and discriminative ability for postoperative adverse events after total shoulder arthroplasty (TSA) than simple variables. QUESTIONS/PURPOSES: Using a large research database to examine postoperative adverse events after anatomic and reverse TSA, we asked: (1) Which demographic/anthropometric variable among age, sex, and body mass index (BMI) has the best discriminative ability as measured by receiver operating characteristics (ROC)? (2) Which comorbidity index, among the American Society of Anesthesiologists (ASA) classification, the mCCI, or the mFI, has the best ROC? (3) Does a combination of a demographic/anthropometric variable and a comorbidity index provide better ROC than either variable alone? METHODS: Patients who underwent TSA from 2005 to 2015 were identified from the National Surgical Quality Improvement Program (NSQIP). This multicenter database with representative samples from more than 600 hospitals in the United States was chosen for its prospectively collected data and documented superiority over administrative databases. Of an initial 10,597 cases identified, 70 were excluded due to missing age, sex, height, weight, or being younger than 18 years of age, leaving a total of 10,527 patients in the study. Demographics, medical comorbidities, and ASA scores were collected, while BMI, mCCI and mFI were calculated for each patient. Though all required data variables were found in the NSQIP, the completeness of data elements was not determined in this study, and missing data were treated as being the null condition. Thirty-day outcomes included postoperative severe adverse events, any adverse events, extended length of stay (LOS, defined as > 3 days), and discharge to a higher level of care. ROC analysis was performed for each variable and outcome, by plotting its sensitivity against one minus the specificity. The area under the curve (AUC) was used as a measure of model discriminative ability, ranging from 0 to 1, where 1 represents a perfectly accurate test, and 0.5 indicates a test that is no better than chance. RESULTS: Among demographic/anthropometric variables, age had a higher AUC (0.587-0.727) than sex (0.520-0.628) and BMI (0.492-0.546) for all study outcomes (all p < 0.050), while ASA (0.580-0.630) and mFI (0.568-0.622) had higher AUCs than mCCI (0.532-0.570) among comorbidity indices (all p < 0.050). A combination of age and ASA had higher AUCs (0.608-0.752) than age or ASA alone for any adverse event, extended LOS, and discharge to higher level of care (all p < 0.05). Notably, for nearly all variables and outcomes, the AUCs showed fair or moderate discriminative ability at best. CONCLUSION: Despite the use of existing comorbidity indices adapted to large databases such as the NSQIP, they provide no greater association with adverse events after TSA than simple variables such as age and ASA status, which have only fair associations themselves. Based on database-specific coding patterns, the development of database- or NSQIP-specific indices may improve their ability to provide preoperative risk stratification. LEVEL OF EVIDENCE: Level III, diagnostic study.

Return to Sport and Work After High Tibial Osteotomy With Concomitant Medial Meniscal Allograft Transplant.

PURPOSE: (1) To examine the timeline of return to sport (RTS) and return to work (RTW) after high tibial osteotomy (HTO) with concomitant medial meniscal allograft transplant (MAT), (2) to evaluate the degree of function on RTS and RTW, and (3) to identify reasons patients do not return to sport- or work-related activity. METHODS: Patients undergoing HTO plus MAT were reviewed retrospectively at a minimum of 2 years postoperatively. The exclusion criterion was any concomitant procedure except cartilage restoration for focal full-thickness medial femoral condylar defects. Patients completed a subjective sport and work questionnaire, a visual analog scale for pain, the Single Assessment Numeric Evaluation, and a satisfaction questionnaire. RESULTS: Twenty-two patients (aged 35.1 ± 8.1 years) were included at 9.3 ± 3.7 years postoperatively. Sixteen patients participated in sports within 3 years before surgery, and 14 patients (87.5%) returned to sport by 9.7 ± 3.8 months postoperatively. Only 7 patients (43.8%) returned to their preinjury status. Eighteen patients were employed within 3 years before surgery, and all patients returned to work; however, only 16 patients (88.9%) returned at the same occupational intensity by 3.1 ± 2.4 months. The rates of RTW for light-, medium-, and heavy-intensity occupations were 100%, 75.0%, and 85.7%, respectively, whereas the duration of RTW was 2.1 months, 2.3 months, and 4.8 months, respectively. Of the patients, 20 (90.9%) reported at least 1 complaint postoperatively, with 13 patients (59.1%) returning to the operating room for recurrent symptoms, including 1 patient who received a knee replacement at 7.75 years postoperatively. CONCLUSIONS: In patients with medial meniscal deficiency and varus deformity, HTO plus MAT provided high rates of RTS (87.5%) and RTW (100%) by 9.7 months and 3.1 months, respectively. It is imperative that clinicians manage expectations because patients may RTS and RTW after HTO plus MAT; however, return to high-intensity activities or occupations may be unlikely or delayed.

Open Biceps Tenodesis Associated With Slightly Greater Rate of 30-Day Complications Than Arthroscopic: A Propensity-Matched Analysis.

PURPOSE: To compare the early complication risk associated with open biceps tenodesis (OBT) and arthroscopic biceps tenodesis (ABT) and determine which preoperative factors may influence complication rate. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was retrospectively queried from 2008 to 2016 for all procedures with CPT codes for ABT (29828) and OBT (23430). Patients were excluded if they received concomitant rotator cuff repair or shoulder arthroplasty. Patients undergoing OBT and ABT were matched by propensity scores based on age, body mass index, operative time, proportion of smokers, and proportion of concomitant subacromial decompression, distal clavicle excision, SLAP, and debridement. The incidence of adverse events in the 30-day postoperative period was compared. RESULTS: A total of 8,032 patients met the inclusion and exclusion criteria. Prior to propensity match, patients receiving OBT and ABT, respectively, differed with respect to age (49.4 ± 13.8 vs 51.4 ± 13.2; P < .001), body mass index (29.6 ± 6.8 vs 29.9 ± 7.0; P = .029), and operative time (91.2 ± 51.3 vs 85.3 ± 43.4; P < .001). Following propensity match, 6,330 remained in the study (3,165 ABT and 3,165 OBT). OBT had significantly greater incidence of any adverse events (1.58% vs 0.95%; P = .032) and anemia requiring transfusion (0.35% vs 0%; P = .001). Multivariate analysis suggested that OBT (relative risk [RR] = 1.7, 95% confidence interval [CI], 1.1-2.7; P = .020), old age (RR = 1.6, 95% CI, 1.0-2.5), history of dyspnea (RR = 3.8, 95% CI, 1.8-7.7; P < .001), and congestive heart failure (RR = 5.5, 95% CI, 1.3-22.7; P = .019) were associated with developing a postoperative adverse event within 30 days of surgery. CONCLUSIONS: Both procedures were found to have a low rate of complications, although OBT had a slightly greater (1.58% vs 0.95%) rate of 30-day complications than ABT. Early complication rate should not serve as impetus to direct surgical technique as number needed to treat is high, although ABT may be considered in more high-risk individuals. LEVEL OF EVIDENCE: Level III, retrospective comparative database study.

Operative Time as an Independent and Modifiable Risk Factor for Short-Term Complications After Knee Arthroscopy.

PURPOSE: To determine whether operative time is an independent risk factor for 30-day complications after arthroscopic surgical procedures on the knee. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried between 2005 and 2016 for all arthroscopic knee procedures including lateral release, loose body removal, synovectomy, chondroplasty, microfracture, and meniscectomy. Cases with concomitant procedures were excluded. Correlations between operative time and adverse events were controlled for variables such as age, sex, body mass index, patient comorbidities, and procedure using a multivariate Poisson regression with robust error variance. RESULTS: A total of 78,864 procedures met our inclusion and exclusion criteria. The mean age of patients was 51.0 ± 14.3 years; mean operative time, 31.2 ± 18.1 minutes; and mean body mass index, 31.0 ± 7.8. Arthroscopic lateral release (coefficient, 5.8; 95% confidence interval [CI], 4.8-6.8; P < .001), removal of loose bodies (coefficient, 4.2; 95% CI, 3.2-5.3; P < .001), synovectomy (coefficient, 1.8; 95% CI, 1.2-2.3; P < .001), and microfracture (coefficient, 6.5; 95% CI, 5.8-7.2; P < .001) had significantly greater durations of surgery in comparison with meniscectomy. The overall rate of adverse events was 1.24%. After we adjusted for demographic characteristics and the procedure, a 15-minute increase in operative duration was associated with an increased risk of transfusion (relative risk [RR], 1.5; 95% CI, 1.3-1.8; P < .001), death (RR, 1.6; 95% CI, 1.2-2.1; P = .005), dehiscence (RR, 1.6; 95% CI, 1.2-2.2; P = .002), surgical-site infection (RR, 1.3; 95% CI, 1.2-1.3; P = .001), sepsis (RR, 1.3; 95% CI, 1.2-1.4; P < .001), readmission (RR, 1.1; 95% CI, 1.1-1.2; P < .001), and extended length of stay (RR, 1.4; 95% CI, 1.3-1.4; P < .001). CONCLUSIONS: Marginal increases in operative time are associated with an increased risk of adverse events such as surgical-site infection, sepsis, extended length of stay, and readmission. Efforts should be made to maximize surgical efficiency. LEVEL OF EVIDENCE: Level IV, retrospective database study.

Comparative analysis of work-related outcomes in hemiarthroplasty with concentric glenoid reaming and total shoulder arthroplasty.

BACKGROUND: Anatomic total shoulder arthroplasty (aTSA) has demonstrated high levels of return to work, although there are fears of glenoid component loosening with higher work demand. METHODS: A retrospective query was performed of all patients who received hemiarthroplasty with ream-and-run resurfacing (Hemi RR) between 2005 and 2014. Included patients were matched to an aTSA cohort by age, body mass index, sex, and hand dominance. Preoperative and postoperative work status, by level of duty and occupation, was collected. RESULTS: Twenty-five patients receiving Hemi RR and 28 patients receiving TSA completed this questionnaire (82.8% compliance). Mean follow-up was 69.1 ± 24.8 months. In total, 100% of Hemi RR patients returned to work, and 89.3% of TSA patients returned to work (P = .091). The Hemi RR patients had higher rates of return to work for heavy-duty workers only (7 of 7 vs. 2 of 4, P = .038), although only 1 patient in the TSA group reported failure to work was due to shoulder reasons. Mean duration of return to work was 2.5 ± 4.8 months for patients receiving Hemi RR and 1.98 ± 2.6 months for those receiving TSA (P = .653). CONCLUSIONS: Hemi RR had a high return to heavy-duty work, likely due to fewer surgeon-imposed restrictions. The results of this study may help manage return to work expectations after Hemi RR according to the level of duty and suggest Hemi RR is a viable option for heavy-duty laborers with end-stage glenohumeral arthritis.

Imaging Diagnosis of Injury to the Anterolateral Ligament in Patients With Anterior Cruciate Ligaments: Association of Anterolateral Ligament Injury With Other Types of Knee Pathology and Grade of Pivot-Shift Examination: A Systematic Review.

PURPOSE: The purpose of this study is to systematically review the literature to evaluate the reliability, or the ability of a repeated measurement to yield consistent results, and validity of ultrasound (US) and magnetic resonance imaging (MRI) at evaluating anatomy and pathology of the anterolateral ligament of the knee (ALL) in the setting of anterior cruciate ligament (ACL) injuries. Furthermore, the incidence and association of ALL injury with the pivot-shift examination, and other structural injuries, will be reviewed for additional clinical relevance. METHODS: Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 2 reviewers independently searched the Medline, Embase, Cochrane, EBSCOhost, OVID, and Web of Science databases for all studies related to imaging of the ALL. All eligible articles and their references were screened by both reviewers. Studies discussing diagnostic imaging of the ALL with regard to identification of injury to the structure in patients with suspected ACL injury were included. No restrictions regarding date of publication, type of publication, or language in the included article were applied. The exclusion criteria included commentaries, case reports, and studies that did not attempt to identify the ALL as a discrete structure. Quality assessment and data extraction was performed for each included study before final analysis was performed. RESULTS: A total of 13 articles were included for final analysis. In the included studies, at least 1 portion of the ALL could be visualized on MRI in 76% to 100% of knees, and injury to the ALL was identified in 10.8% to 62.5% of patients. Inter- and intraobserver reliabilities ranged from moderate to almost perfect. There was a consensus among studies that ALL injuries were significantly associated with injuries to the lateral collateral ligament, popliteus tendon, iliotibial band, and bony contusions to the lateral tibia and femur. Most of the included studies found a significant association of injuries to the ALL and a high-grade pivot-shift examination. Only 2 studies used US to evaluate for injury to the ALL, and both studies had almost perfect interobserver reliability. Only 1 study confirmed initial diagnoses at the time of the ACL reconstruction surgery. CONCLUSIONS: In patients with ACL injuries, concomitant ALL injuries can be identified on MRI or US with high levels of inter- and intraobserver reliability, and are often associated with a high-grade pivot-shift examination, lateral collateral ligament injury, and lateral femoral condyle and tibial plateau bone bruises. LEVEL OF EVIDENCE: Level IV, systematic review of level II-IV studies.

Recurrence Rate of Instability After Remplissage for Treatment of Traumatic Anterior Shoulder Instability: A Systematic Review in Treatment of Subcritical Glenoid Bone Loss.

PURPOSE: To report outcomes after arthroscopic remplissage in patients with anterior shoulder instability and subcritical glenoid bone loss, specifically regarding recurrence of instability, return to sport, and changes in range of motion. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to perform a search using the PubMed, Embase, Cochrane Library, and Scopus databases. Forest plots were used to evaluate the overall values for recurrent instability, change in external rotation, and return to sport after arthroscopic Bankart repair with or without remplissage. The Methodological Index for Non-randomized Studies and Risk of Bias in Nonrandomized Studies-Interventions checklist were used to evaluate bias. RESULTS: Twenty-two articles met the inclusion and exclusion criteria. The Methodological Index for Non-randomized Studies and Risk of Bias in Nonrandomized Studies-Interventions checklists deemed studies as acceptable quality with low bias. Among 694 patients (522 male and 106 female patients) undergoing remplissage, the mean age was 28.3 ± 5.3 years and the mean duration of follow-up was 32.5 ± 13.9 months. The recurrence rate of instability ranged from 0% to 20%. The change in external rotation in 90° of abduction ranged from -11.3° to -1.0°, and the change in external rotation with the arm fully adducted ranged from -8.0° to +4.5°. The overall rate of return to sport ranged from 56.9% to 100% after remplissage. The rate of return to sport at the preinjury level ranged from 41.7% to 100%. In addition, arthroscopic remplissage in addition to Bankart repair had a reduced odds of recurrent instability developing, ranging from 0.07 to 0.88, when compared with isolated Bankart repair. CONCLUSIONS: Arthroscopic remplissage combined with Bankart repair is an effective procedure in the treatment of patients with engaging Hill-Sachs lesions and minimal glenoid bone loss. Patients can expect favorable rates of recurrent instability with a negligible loss of external rotation when compared with isolated Bankart repair. Treatment algorithms may be updated to include this procedure for engaging Hill-Sachs lesions, measuring between 20% and 40% in volume, with subcritical (<20%) glenoid bone loss. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and IV studies.

Return to Sports After Tibial Tubercle Osteotomy for Patellofemoral Pain and Osteoarthritis.

PURPOSE: To determine the rate of return to sports and clinical outcomes after anteromedialization (AMZ) tibial tubercle osteotomy (TTO) for patients with patellofemoral pain and/or osteoarthritis. METHODS: This study is a retrospective case series of consecutive patients who underwent unilateral or staged bilateral AMZ TTO for a primary diagnosis of patellofemoral pain or arthritis. Included were all patients with minimum 1-year follow-up. The indication for surgery was failure of at least 6 months of nonoperative treatment. Simultaneous tubercle distalization or proximal-medial soft-tissue procedures were excluded; however, prior patellar instability procedures did not prohibit inclusion if there was no recurrence. A diagnostic arthroscopy was performed to evaluate the cartilage surfaces; AMZ TTO was performed by use of a freehand technique and two 4.5-mm fully threaded screws for fixation. A gradual return to activities was permitted at 6 months; however, contact sports were prohibited until 9 months postoperatively. Patients were evaluated retrospectively for participation in sports using a questionnaire about the level of participation, return to sporting activities, and Kujala score. Statistical analysis included 1-way analysis of variance and χ2 or Fisher exact and paired t tests. RESULTS: Forty-eight patients played sports within 3 years before surgery. The majority were female patients (84.2%). The average age at surgery was 29.6 years, with an average follow-up period of 4.6 years. The average Kujala score improved from 51.2 to 82.6 (P < .0001); the average pain score improved from 4.1 to 1.8 (P < .001). Of the patients, 83.3% returned to at least 1 sport on average 7.8 months postoperatively. Of these, 77.5% believed they returned to sports at the same level or a higher level. CONCLUSIONS: Patients undergoing AMZ TTO for patellofemoral pain or arthritis had an 83.3% rate of return to 1 or more sporting activities at an average of 7.8 months after surgery, with many patients returning at the same level or a higher level of intensity compared with their preoperative state. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Return to sport after shoulder arthroplasty: a systematic review and meta-analysis.

PURPOSE: With increasing incidence and indications for shoulder arthroplasty, there is an increasing emphasis on the ability to return to sports. The main goal of this study was to determine the rate of return to sport after shoulder arthroplasty. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to perform this systematic review and meta-analysis. A search was performed on MEDLINE, Scopus, EMBASE, and the Cochrane Library. The quality of the included studies was evaluated according to the Methodological Index for Nonrandomized Studies checklist. The main judgement outcome was the rate of return to sports activity after shoulder arthroplasty and the level of play upon return (identical or higher/lower level). RESULTS: Thirteen studies were reviewed, including 944 patients (506 athletes), treated with shoulder arthroplasty at an average follow-up of 5.1 years (range, 0.5-12.6 years). The most common sports were swimming (n = 169), golf (n = 144), fitness sports (n = 71), and tennis (n = 63). The overall rate of return to sport was 85.1% (95% CI, 76.5-92.3%), including 72.3% (95% CI, 60.6-82.8%) returning to an equivalent or improved level of play, after 1-36 months. Patients undergoing anatomic total shoulder arthroplasty returned at a significantly higher rate (92.6%) compared to hemiarthroplasty (71.1%, p = 0.02) or reverse total shoulder arthroplasty (74.9%, p = 0.003). CONCLUSION: Most patients are able to return to one or more sports following shoulder arthroplasty, with anatomic total shoulder arthroplasty having the highest rate of return. LEVEL OF EVIDENCE: IV.

High Short-Term Failure Rate Associated With Decellularized Osteochondral Allograft for Treatment of Knee Cartilage Lesions.

PURPOSE: To report the short-term clinical and radiographic outcomes following the use of decellularized osteochondral (OC) allograft plugs in the treatment of distal femoral OC lesions. METHODS: An Institutional Review Board-approved database with prospectively collected data was used to identify patients treated with the decellularized OC allograft plugs implant. Demographic information, patient-reported outcomes, magnetic resonance imaging (MRI), and the number and type of reoperations were assessed. Failure was defined as revision surgery with removal of the implant. Patients were evaluated pre- and postoperatively using the Short Form-36, Activity of Daily Living Score, International Knee Documentation Committee Subjective Evaluation, Cincinnati Knee Rating System, and Marx Activity Scale. MRIs were evaluated using the OsteoChondral Allograft MRI Scoring System. RESULTS: Thirty-four patients were identified, with a mean age of 45 (±11.9) years; 71% were male. Fifteen (44%) patients had undergone prior ipsilateral surgical intervention. Mean defect size was 4 (±1.5) cm2, and median number of allografts per knee was 2 (range, 1-5). Mean follow-up duration was 15.5 months (range, 6-24). Ten patients (29%) required revision surgery with removal of the implant. Implant survivorship was 61% at 2 years. Female gender was independently predictive of failure, with a hazard ratio of 9.4 (95% confidence interval [CI], 2.0-58.9; P = .005). Defect size was also independently predictive of failure, with a hazard ratio of 1.9 per 1 cm2 increase (95% CI, 1.2-3.1; P = .005). MRIs obtained at 1 year postoperatively demonstrated significantly improved osseous integration (P = .0086) and opposing cartilage (P = .019) in the nonfailure group as compared with the failure group. CONCLUSIONS: Based on the high short-term failure rate observed in this study, the authors advise that a decellularized OC allograft plugs implant should be used with caution in the treatment of OC lesions of the knee, as similar outcomes have not been noted with other cartilage restoration techniques. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
