Radiographic and anatomic variations on postoperative acromion fractures after inlay and lateralized reverse shoulder arthroplasty.

INTRODUCTION: Postoperative fracture of the acromion is a complication uniquely more common after reverse shoulder arthroplasty (RSA) than other forms of shoulder arthroplasty. There is limited knowledge regarding the etiology of these fractures or the anatomic risk factors. The purpose of this study is to identify associations of the acromioclavicular (AC) joint and relative humeral and glenoid positioning on the occurrence of acromial fractures after RSA. METHODS: A retrospective case-controlled study was performed on primary RSA patients treated by a single surgeon from September 2009 to September 2019. Patients with a postoperative acromion fracture were matched in a 3:1 ratio based on gender, indication, and age to those without a fracture and with a 2-year minimum follow-up. Preoperative and the immediate postoperative radiographs were reviewed by 2 investigators to measure critical shoulder angle, acromion-humeral interval, global lateralization, delta angle, preoperative glenoid height, and the level of inlay or onlay of the humeral stem. The morphology, width, and stigmata of osteoarthritis in the AC joint were assessed using computed tomography scans taken preoperatively. RESULTS: Of a total of 920 RSAs performed, 47 (5.1%) patients suffered a postoperative acromion fracture. These patients were compared with a control group of 141 patients, with a mean age of 76.4 years and similar distributions of gender and surgical indication. Patients in both groups had similar preoperative glenoid height (P = .953) and postoperative degree of inset or offset of humeral implant relative to the anatomic neck (P = .413). There were no differences in critical shoulder angle, acromion-humeral interval, global lateralization, and delta angle both preoperatively and postoperatively between the fracture and nonfracture groups. Computed tomography analysis also showed no differences in AC joint morphology (P = .760), joint space (P = .124), and stigma of osteoarthritis (P = .161). CONCLUSION: There was no relation between the features of the AC joint and the anatomic parameters of the humerus relative to the glenoid and acromion on postoperative acromion fractures after RSA.

Iron deficiency anemia is associated with increased medical and implant-related complications and length of stay for patients undergoing total shoulder arthroplasty.

BACKGROUND: Iron deficiency anemia (IDA) is associated with decreased bone mineral density and osteoporosis; however, studies investigating the effects of IDA in patients undergoing primary total shoulder arthroplasty (TSA) have not been well studied. The purpose of this study is to utilize a nationwide administrative claims database to investigate whether patients with diagnosed IDA undergoing primary TSA have higher rates of 1) in-hospital length of stay (LOS); 2) medical complications; and 3) implant-related complications. METHODS: A retrospective review from 2005 to 2014 was conducted using the Medicare Standard Analytical Files. Patients with IDA undergoing primary TSA were identified and matched to controls without IDA, in a 1:5 ratio by age, sex, and medical comorbidities. Outcomes analyzed included in-hospital LOS and 90-day medical and implant-related complications. Mann-Whitney U tests compared in-hospital LOS, and multivariate logistic regression was used to calculate odds ratios (ORs) on the effects of IDA on postoperative complications after adjusting for age, sex, and Elixhauser Comorbidity Index. RESULTS: A total of 17,689 patients with IDA and 88,445 without IDA participated in the matched-cohort analysis, with no differences in age, gender, and comorbidities (P = .99). IDA patients were found to have significantly longer in-hospital LOS (3-days vs. 2-days, P < .0001). IDA patients were also found to have significantly higher odds of 90-day implant-related complications (OR: 1.65, P < .0001), such as periprosthetic joint infections (OR: 1.80, P < .0001) and 90-day medical complications (OR: 2.87, P < .0001), including blood transfusions (OR: 10.37, P < .0001). CONCLUSION: Patients with IDA undergoing primary TSA have significantly longer in-hospital LOS, and medical and implant-related complications. Patients were 10 times more likely to undergo a blood transfusion and 2 times more likely to have a periprosthetic fracture.

Comparison of reverse shoulder arthroplasty and total shoulder arthroplasty for patients with inflammatory arthritis.

BACKGROUND: End-stage glenohumeral joint arthritis is common in patients with inflammatory arthritis. Reverse shoulder arthroplasty (RSA) and anatomic total shoulder arthroplasty (TSA) are both indicated in this setting. RSA is often considered based on the impacts of long-standing inflammatory arthritis including glenoid and humeral bone erosion and rotator cuff insufficiency. However, acromial and scapular spine fractures following RSA have been reported more commonly in these patients, which can have a significant impact on outcomes. Currently, no study has directly compared the efficacy and complication rates of RSA vs. TSA in patients with inflammatory arthritis. This study aimed to investigate differences in clinical outcomes and complications in patients undergoing RSA vs. TSA with glenohumeral inflammatory arthritis. METHODS: We performed a retrospective review of 86 patients with inflammatory arthritis treated with primary RSA (n = 43) or TSA (n = 43) with a minimum of 2 years' follow-up. American Shoulder and Elbow Surgeons scores, Simple Shoulder Test scores, visual analog scale scores for pain and function, active range of motion, and patient self-ratings of upper-extremity normality (Subjective Assessment of Normal Evaluation [SANE]) were collected preoperatively and at minimum 2-year follow-up. Radiographic classification of preoperative glenoid and humeral bone loss was performed, and postoperative complications were observed. Revision and complication details were compared. RESULTS: The study cohort had an average age of 72.1 years (range, 31-92 years) and average follow-up period of 51.6 months (range, 22-159 months). Both the RSA and TSA cohorts demonstrated improvements in patient-reported outcome measures and ranges of motion; however, patients treated with TSA showed a greater postoperative final Simple Shoulder Test score (P < .001), visual analog scale score for function (P = .0347), active elevation (P = .0331), active external rotation (P < .001), active internal rotation (P = .005), and Single Assessment Numeric Evaluation (SANE) score (P = .0161). Analysis of complication rates demonstrated no statistically significant difference between cohorts. Four acromial fractures occurred in the RSA group. When RSA patients who sustained acromial fractures were removed from the analysis, there were minimal differences in outcomes between the RSA and TSA cohorts. CONCLUSION: TSA in patients with inflammatory arthritis leads to improved clinical outcomes but higher early revision rates when compared with RSA. RSA outcomes are negatively impacted by a high rate of postoperative acromial fractures.

Nonoperative treatment of acromial fractures following reverse shoulder arthroplasty: clinical and radiographic outcomes.

BACKGROUND: Acromion/scapular spine fractures (ASFs) remain a challenging complication following reverse shoulder arthroplasty (RSA). Historically, nonoperative management has been the treatment of choice, with variable results. The purpose of this study is to report on both clinical and radiographic outcomes of nonoperative treatment. A new subclassification of Levy type II acromion fractures will be proposed, and outcomes will be evaluated in relation to the modified Levy classification. METHODS: Forty-four patients diagnosed with ASF following RSA were matched 1:3 to a control group based on gender, age, and preoperative function. All ASF patients were treated nonoperatively. Patient-reported outcome measures, consisting of American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, Simple Shoulder Test, Single Assessment Numerical Evaluation, visual analog scale pain and function scores, satisfaction, and active range of motion were gathered preoperatively and at the most recent follow-up. Outcomes were stratified based on fracture type. Radiographic findings including fracture union, scapular rotation, progressive notching, and osteolysis were reviewed from latest follow-up and compared with initial postoperative films. RESULTS: ASFs were identified at a median of 2 months following RSA (8 type I; 22 type II; 14 type III), followed for a median of 37 months and compared to 108 matched controls. Patients with ASF had inferior clinical outcomes with a higher rate of dissatisfaction (27.8%) when compared to controls. Lateral fracture subtypes (I and IIA) were similar to controls and had little impact on outcomes. However, medial fracture subtypes (type IIB, IIC, and III) demonstrated inferior outcomes when compared to controls, with type III fracture patients demonstrating no improvement from baseline. The overall nonunion rate was 61.4%, with high rates of scapular rotation and osteolysis in medial fracture subtypes. Nonunion was associated with a higher incidence of secondary radiographic findings, including scapular rotation, progressive notching, and osteolysis. CONCLUSION: Results of nonoperative treatment of ASF following RSA differs based on fracture location. Fractures that occur at or medial to the glenoid face (IIB, IIC, III) demonstrate high rates of unsatisfactory results and worse clinical outcomes. Concerning radiographic findings of scapular tilt, progressive scapular notching and osteolysis were seen at a higher rate with medial fracture types and fracture nonunions.

Does application of hydrogen peroxide to the dermis reduce incidence of Cutibacterium acnes during shoulder arthroplasty: a randomized controlled trial.

INTRODUCTION: Prosthetic joint infections (PJIs) following shoulder arthroplasty are a major source of morbidity and are most commonly caused by Cutibacterium acnes, a bacteria found concentrated in the dermis. Skin preparation using hydrogen peroxide has been shown to reduce positive cultures; however, direct application to the dermis has not been investigated. The purpose of this study is to determine whether the application of hydrogen peroxide to the dermis affects the incidence of positive C acnes cultures. METHODS: A prospective, randomized controlled trial of patients undergoing primary shoulder arthroplasty by a single fellowship-trained surgeon was performed between February and November 2020. Enrolled patients were randomized to either receive standard skin preparation and antibiotic prophylaxis with or without an additional application of hydrogen peroxide to the dermis following incision. Culture samples were taken from the skin, dermis, glenohumeral joint, and air. Laboratory personnel and patients were blinded to randomization, and all cultures were held for 14 days. Culture positivity rate along with culture site, day of culture positivity, and bacterial abundance of positive cultures were analyzed. Stratified analysis by gender and age of ≤69 years was also performed. RESULTS: Sixty patients undergoing primary arthroplasty were randomized. The group receiving hydrogen peroxide (n =30) and the control group (n = 30) were similar in age (71.1 ± 7.1 vs. 73.4 ± 9.8; P = .30), body mass index (29.4 ± 5.7 vs. 28.5 ± 6.0; P = .57), gender (P = .64), hand dominance (P = .65), and surgery type (P = .90). The overall rate of at least 1 positive culture was 18%. All positive cultures were C acnes. The positive culture rate in the hydrogen peroxide (20%) and control group were similar (16%; P > .99). There were no positive glenohumeral joint cultures and no wound complications. There was no significance difference in the culture site, day of culture positivity, and bacterial abundance. Stratification analysis by gender and age also demonstrated similar rates of C acnes between study groups. CONCLUSION: Standard skin preparation and antibiotic prophylaxis results in an overall low rate of skin and dermis culture positivity. The use of hydrogen peroxide after initial incision did not significantly alter the rate of positive C acnes cultures during shoulder arthroplasty and did not increase wound complications.

Determining the validity of the Outpatient Arthroplasty Risk Assessment (OARA) tool for identifying patients for safe same-day discharge after primary shoulder arthroplasty.

BACKGROUND: Early discharge has been a target of cost-control efforts given the growing demand for joint replacement surgery. The Outpatient Arthroplasty Risk Assessment (OARA) score, a medically based risk-assessment score, has shown high predictive ability in achieving safe early discharge following outpatient lower-extremity arthroplasty using a score threshold initially set at ≤59 points but more recently adapted to ≤79 points. However, no study has been performed using the OARA tool for shoulder replacement, which has been shown to have lower associated medical risks than lower-extremity arthroplasty. The purpose of this study was to determine the OARA score threshold for same-day discharge (SDD) following shoulder arthroplasty and evaluate its effectiveness in selecting patients for SDD. We hypothesized that the OARA score threshold for shoulder arthroplasty would be higher than that for lower-extremity arthroplasty. METHODS: We performed a retrospective review of 422 patients who underwent primary anatomic or reverse shoulder arthroplasty between April 2018 and October 2019 performed by a single surgeon. As standard practice, all patients were counseled preoperatively regarding SDD and given the choice to stay overnight. Medical history, length of stay, and 90-day readmissions were obtained from medical records. Analysis of variance testing and screening test characteristics compared the performance of the OARA score vs. the American Society of Anesthesiologists Physical Status (ASA-PS) class and a previously published OARA score threshold used to define a low risk of outpatient lower-extremity arthroplasty. RESULTS: A preoperative OARA score cutoff of ≤110 points demonstrated a sensitivity of 98.0% for identifying patients with SDD after shoulder arthroplasty, compared with 66.7% using the hip and knee OARA score threshold of ≤59 points (P < .0001) and 80.4% using ASA-PS class ≤ 2 (P = .008). OARA scores ≤ 110 points also showed a negative predictive value of 98.9% and a false-negative rate of 2.0% but remained incomprehensive with a specificity of 24.0% (P < .0001). Analysis of variance demonstrated that mean OARA scores increased significantly with length of stay (P = .001) compared with ASA-PS classes (P = .82). Patients with OARA scores ≤ 110 points were also 2.5 times less likely to have 90-day emergency department visits (P = .04) than those with OARA scores > 110 points. There was no difference in 30- and 90-day readmission rates for patients with OARA scores ≤ 59 points, OARA scores ≤ 110 points, and ASA-PS classes ≤ 2. CONCLUSION: Our study suggests that a preoperative OARA score threshold of ≤110 points is effective and conservative in screening patients for SDD following shoulder arthroplasty, with low rates of 90-day emergency department visits and readmissions. This threshold is a useful screening tool to identify patients who are not good candidates for SDD.

Pigmented Villonodular Synovitis of the Hip in Patients Undergoing Total Hip Arthroplasty: A Retrospective Case-Controlled Analysis.

BACKGROUND: Pigmented villonodular synovitis (PVNS) is a condition affecting larger joints such as the hip and knee. Little is known regarding the impact of PVNS on total hip arthroplasty (THA). Therefore, the aim of this study is to determine if patients with PVNS of the hip undergoing primary THA experience greater (1) in-hospital lengths of stay (LOS); (2) complications; (3) readmission rates; and (4) costs. METHODS: Patients undergoing primary THA for PVNS of the hip from the years 2005 to 2014 were identified using a nationwide claims registry. PVNS patients were matched to a control cohort in a 1:5 ratio by age, gender, and various comorbidities. The query yielded 7440 patients with (n = 1240) and without (n = 6200) PVNS of the hip undergoing primary THA. Endpoints analyzed included LOS, complications, readmission rates, and costs. Multivariate logistic regression was used to determine odds ratios (OR) of developing complications. Welch's t-tests were used to test for significance in LOS and cost between the cohorts. A P-value less than .001 was considered statistically significant. RESULTS: PVNS patients had approximately 8% longer in-hospital LOS (3.8 vs 3.5 days, P = .0006). PVNS patients had greater odds of (OR 1.60, P < .0001) medical and (OR 1.81, P < .0001) implant-related complications. Furthermore, PVNS patients were found to have higher odds (OR 1.84, P < .0001) of 90-day readmissions. PVNS patients also incurred higher day of surgery ($13,119 vs $11,983, P < .0001) and 90-day costs ($17,169 vs $15,097, P < .0001). CONCLUSION: Without controlling for global trends in LOS, complications, readmissions, or costs between 2005 and 2014, the findings of the study suggest that PVNS of the hip is associated with worse outcomes and higher costs following primary THA. The study is useful as orthopedic surgeons can use the study to educate patients of the complications which may occur following their hip surgery.

Does obesity impact lumbar sagittal alignment and clinical outcomes after a posterior lumbar spine fusion?

PURPOSE: The purpose of this study is to compare clinical patient-reported outcomes and radiographic sagittal parameters between obese and non-obese patients following open posterior lumbar spine fusion (PLSF). METHODS: A retrospective cohort study was conducted for patients who underwent open PLSF from 2011 to 2018. Patients were classified as obese as per Center for Disease Control and Prevention guidelines if their body mass index (BMI) ≥ 30 kg/m2. Preoperative and final visual analog scale (VAS) back pain, VAS leg pain, and Oswestry Disability Index (ODI) were obtained for both obese and non-obese groups. Achievement of minimal clinically important difference was evaluated. Preoperative, immediate postoperative, and final lumbar plain radiographs were assessed to measure spinopelvic parameters. Additionally, postoperative complication measures were collected. RESULTS: A total of 569 patients were included; 290 (50.97%) patients with BMI < 30 (non-obese) and 279 (49.03%) patients with BMI ≥ 30 (obese). Patients classified as obese were more likely to have a diagnosis of diabetes mellitus (p < 0.001), and American Society of Anesthesiologists Physical Status Classification System of ≥ 3 (p < 0.001). Obese patients had significantly longer operative times (p < 0.001) compared to non-obese patients. There was no difference in radiographic measurements, patient-reported outcomes, postoperative complications, or reoperations between groups. CONCLUSION: Obese patients had significantly more comorbidities and longer operative time compared to non-obese patients. However, sagittal parameters, patient-reported outcomes, inpatient complications, length of hospital stay, and reoperations were similar between groups. Given these findings, open PLSF can be considered safe and effective in obese patients after thorough consideration of related comorbidities. These slides can be retrieved under Electronic Supplementary Material.

Characterizations of Capsule Closure in Hip Arthroscopy Are Infrequently and Incompletely Reported: A Systematic Review.

Purpose: To review the recent literature to provide an updated characterization of capsule closure techniques in hip arthroscopy and to determine if the characteristics of closure impacted clinical outcomes. Methods: In keeping with the Preferred Reporting in Systematic Reviews and Meta Analyses (PRISMA) guidelines, a systematic review was performed with the following eligibility criteria: patients over 18 years of age who underwent primary hip arthroscopy with reporting of patient reported outcome measures or revision/failure, and a sufficiently detailed description of capsule closure. The GRADE framework evaluated study quality, and ROBINS-I evaluated the risk of bias. Results: Across 18 studies (N = 3277) an interportal capsulotomy was reported in 12 studies (1972/3277) cases, and a T-type capsulotomy was reported in six studies (1305/3277) cases). Six studies reported using #2 suture. Nonabsorbable suture was reported in six studies, and absorbable suture in six studies. The rate of failure was 10.5% across five studies (N = 1133) and the rate of revision was 4.4% across 13 studies (N = 2957). Conclusions: Capsule closure is commonly performed with #2 high strength suture-the T-type using two to three sutures in the vertical limb and two to three in the transverse limb, and the interportal type using two to three sutures. Compared to earlier reports, there is a trend for increased utilization of T-type capsulotomy. Although there is a growing body of investigations into the efficacy of routine capsule closure following hip arthroscopy, our results demonstrate infrequent and inconsistent reporting of capsule closure characteristics. Level of Evidence: Level IV, systematic review of Level I-IV studies.

Irreparable Rotator Cuff Tear Treated With Combined Reconstruction of the Superior Capsule and Rotator Cuff: Technique Guidelines.

Irreparable rotator cuff tears in young patients can be challenging for the patient and orthopaedic surgeon. Interposition rotator cuff reconstruction has gained popularity in patients with retracted tears and a viable rotator cuff muscle belly. Superior capsular reconstruction is an emerging treatment option that was developed to restore native glenohumeral joint mechanics by creating a superior constraint, which provides a stable glenohumeral fulcrum. Reconstructing both the superior capsule and rotator cuff tendon in the setting of an irreparable tear may improve clinical results in younger patients with viable rotator cuff muscle belly and a maintained acceptable acromiohumeral distance.

Resident Impact on Primary Total Knee Arthroplasty: A Consecutive Series Under a Single Surgeon.

Background: The literature has displayed conflicting evidence on resident involvement in surgical procedures. The goal of this study was to assess the impact of resident involvement on primary total knee arthroplasty (TKA) under a single fellowship-trained adult reconstruction surgeon. Methods: Two hundred sequential patients were retrospectively reviewed by a single surgeon: the first cohort represented the final 100 TKAs performed by the surgeon without resident involvement (NRI), serving as the control group, and the second cohort represented the initial 100 TKAs performed by the same surgeon with resident involvement (RI), serving as the experimental group. Perioperative variables such as number of people in operating room (OR), surgical time, and tourniquet time, and postoperative variables such as infection, minor complications, medial distal femoral angle, medial proximal tibia angle, and total angulation were assessed. Results: The rate of infection was significantly lower in the RI group (0%) compared to the NRI group (1%) (P = .043). The number of staff in the OR (P < .001), the tourniquet time (P < .001), and OR time (P < .001) were significantly higher in the RI group compared to the NRI group. There was no difference in coronal plane radiographic measurements: medial distal femoral angle (P = .10), medial proximal tibia angle (P = .19), or total angulation (P = .27). Conclusions: Resident involvement in primary TKA neither demonstrated any significant difference in coronal plane radiographic alignment of the prosthesis nor an increased risk of infection despite increased operative time, tourniquet time, and number of people in OR. Level of evidence: Level 3 - Therapeutic retrospective cohort study.

Alcohol Abuse, Morbid Obesity, Depression, Congestive Heart Failure, and Chronic Pulmonary Disease are Risk Factors for 90-Day Readmission After Arthroscopic Rotator Cuff Repair.

Purpose: The purpose of this study was to report the rate and causes of 90-day readmissions after arthroscopic rotator cuff repair. Methods: A retrospective query from January 2005 to March 2014 was performed using a nationwide administrative claims registry. Patients and complications were identified using International Classification of Disease, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT) codes. Patients who underwent arthroscopic rotator cuff repair (RCR) and were readmitted within 90 days after their index procedure were identified. Patients not readmitted represented controls. Patients readmitted were stratified into separate cohorts depending on the primary cause of readmission, which included cardiac, endocrine, hematological, infectious, gastrointestinal, musculoskeletal (MSK), neoplastic, neurological or psychiatric, pulmonary, and renal. Risk factors assessed were comorbidities comprising the Elixhauser-Comorbidity Index (ECI). Primary outcomes analyzed and compared included cause for readmission, patient demographics, risk factors, in-hospital length of stay (LOS), and costs. Pearson's chi-square was used to compare patient demographics, and multivariate binomial logistic regression was used to calculate odds ratios (OR) on patient-related risk factors for 90-day readmissions. Results: 10,425 readmitted patients and 301,625 control patients were identified, representing a 90-day readmission rate of 3.5%. The causes of readmissions were primarily related to infectious diseases (15%), MSK (15%), and cardiac (14%) complications. The most common MSK readmissions were osteoarthrosis of the leg or shoulder (24.8%) and spinal spondylosis (8.4%). Multivariate binomial logistic regression analyses demonstrated patients with alcohol abuse (OR, 1.42; P < .0001), morbid obesity (OR, 1.38; P < .0001), depression (OR, 1.35; P < .0001), congestive heart failure (OR, 1.34; P < 0.0001), and chronic pulmonary disease (OR, 1.28; P < .0001) were at the greatest risk of readmissions after RCR. Conclusions: Significant differences exist among patients readmitted, and those patients who do not require hospital readmission within 90 days following arthroscopic rotator cuff repairs. Readmissions are associated with significant patient comorbidities and were primarily related to medically based complications. Level of Evidence: Level III, prognostic, retrospective cohort study.

Clinical Outcomes After Revision Distal Biceps Tendon Surgery.

BACKGROUND: Little is known about the clinical indications of performing a revision distal biceps tendon repair/reconstruction, and there is even less data available on the clinical outcomes of patients after revision surgery. PURPOSE: To determine the clinical outcomes of patients undergoing revision distal biceps tendon repair/reconstruction and evaluate the causes of primary repair failure. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We performed a retrospective review of patients undergoing ipsilateral primary and revision distal biceps tendon repair/reconstruction at a single institution. Between 2011 and 2016, a total of 277 patients underwent distal biceps tendon repair, with 8 patients requiring revision surgery. Patient characteristics, surgical technique, and patient-reported outcome scores (shortened version of Disabilities of Arm, Shoulder and Hand [QuickDASH], 12-Item Short Form Health Survey [SF-12], visual analog scale [VAS] for pain, and Mayo Elbow Performance Score [MEPS]), were assessed. Complications as well as indications for reoperation after primary and revision surgery were examined. RESULTS: The overall revision rate was 2.9%. The number of single- and double-incision techniques utilized were similar among the primary repairs (50% single-incision, 50% double-incision) and revision repairs/reconstructions (62.5% single-incision, 37.5% double-incision). Reasons for reoperation included continued pain and weakness (n = 7), limited range of motion (n = 2), and acute traumatic re-rupture (n = 1). The median duration between primary and revision surgery was 9.5 months (interquartile range [IQR], 5.8-12.8 months). Intraoperatively, the most common finding during revision was a partially ruptured, fibrotic distal tendon with extensive adhesions. At a median of 33.7 months after revision surgery (IQR, 21.7-40.7 months), the median QuickDASH was 12.5 (IQR, 1.7-23.3), MEPS was 92.5 (IQR, 80.0-100), SF-12 mental component measure was 53.4 (IQR, 47.6-58.2), SF-12 physical component measure was 52.1 (IQR, 36.9-55.4), and VAS for elbow pain was 1.0 (IQR, 0-2.0). Revision surgery had a complication rate of 37.5% (3 of 8 patients), consisting of persistent pain and weakness (2 patients; 25%) and numbness over the dorsal radial sensory nerve (1 patient; 12.5%). Two patients required reoperation (25% reoperation rate). CONCLUSION: The overall revision distal biceps repair/reconstruction rate was approximately 3%. While patients undergoing revision distal biceps repair demonstrated improved outcomes after revision surgery, these outcomes remained inferior to previously reported outcomes of patients undergoing only primary distal biceps repair.
