    Title translation Arthroscopic superior capsule reconstruction using a 6 mm thick acellular dermal allograft for irreparable posterosuperior rotator cuff tears.
    Abstract Objective: Implantation of an acellular dermal allograft between glenoid and humerus to restore a stable glenohumeral center of rotation in cases of irreparable posterosuperior rotator cuff tears.
    Indications: Irreparable posterosuperior rotator cuff tears with low-grade cuff tear arthropathy (Hamada grade 1 and 2) and isolated pseudoparesis for flexion.
    Contraindications: Absolute: Infection, nerve lesions (brachial plexus, axillary nerve), concomitant irreparable subscapularis tendon tear, anterosuperior subluxation of the humeral head ("anterosuperior escape"). Relative: Cuff tear arthropathy ≥ Hamada grade 3, fatty infiltration of the infraspinatus muscle ≥ Goutallier grade 2, deficiency of the deltoid muscle, inability to adhere to the rehabilitation program, poor compliance.
    Surgical technique: Arthroscopic fixation of a 6 mm thick acellular dermal allograft with three suture anchors at the superior glenoid rim and a double-row construct at the greater tuberosity. Dorsal and ventral interval closure with side-to-side sutures.
    Postoperative management: Abduction brace for 6 weeks with passive mobilization. Active motion exercises are commenced at 6 weeks with progression to strengthening exercises after 12 weeks.
    Results: Between April 2019 and September 2020, 15 patients (5 women and 10 men) underwent arthroscopic superior capsule reconstruction using a 6 mm thick acellular dermal allograft for treatment of irreparable posterosuperior rotator cuff tears. After a mean follow-up of 15.4 ± 5.5 months, there was a significant improvement in active flexion (102° ± 37°

    Abstract Background: Excellent results have been reported for anatomic total shoulder arthroplasty (TSA) for the treatment of primary glenohumeral osteoarthritis (GHOA). We aim to assess the recovery curve and longitudinal effects of time, age, sex, and glenoid morphology on patient-reported outcomes (PROs) after primary anatomic TSA for primary GHOA.
    Methods: Patients who underwent primary anatomic TSA over 5 years ago were included: Short-Form 12 Physical Component Summary, American Shoulder and Elbow Surgeons scores, Quick Disabilities of the Arm Shoulder and Hand Score, Single Assessment Numeric Evaluation, and patient satisfaction were assessed. Linear mixed-effects models were used to model progression in PROs longitudinally. Unadjusted models and models controlling for sex and age were constructed.
    Results: Eighty-one patients (91 shoulders) were included. Significant improvements from the preoperative period to 1 year postoperatively in the median American Shoulder and Elbow Surgeons (48 to 93;
    Conclusion: Patients undergoing anatomic TSA for primary GHOA showed excellent improvement in PROs and satisfaction in the first year, and these results were maintained postoperatively for a minimum of 5 years. Age- and sex-adjusted models or glenoid morphology did not substantially alter any trends in PROs postoperatively.

    Abstract Background: Rotator cuff tears among patients under 50 years either result from an adequate trauma or are considered non-traumatic due to work-related or athletic overuse. The impact of these different mechanisms on postoperative functional outcomes and tendon healing has not yet been fully understood. Therefore, it was the purpose of this study to investigate the influence of etiology of (antero-)superior rotator cuff tears on postoperative outcomes and the healing rates after arthroscopic rotator cuff repair in a young patient population.
    Methods: Patients under 50 years who underwent arthroscopic rotator cuff repair between 2006-2017 for an anterosuperior rotator cuff tear with a minimum follow up of 24 months were included in this study. Revision surgeries or reconstructive concomitant procedures other than long head of the biceps tenodesis were excluded. Patients were divided into two groups according to the etiology of their rotator cuff tear (traumatic vs. non-traumatic). Demographic and outcome scores including the American Shoulder and Elbow Surgeons (ASES) score, the Constant Score (CS), bilateral strength measurements and postoperative tendon integrity evaluated on magnetic resonance imaging (MRI) were assessed and compared between both groups.
    Results: The mean follow up for this study was 55.6 months (24 - 158). Twenty-one patients (50.0%) had a traumatic RCT and 21 patients (50.0%) had a non-traumatic tear. Outcome scores did not differ significantly between groups. Strength measurements of the supraspinatus revealed significantly decreased force of the affected side as opposed to the contralateral side (p = 0.001), regardless of etiology. Retear rates were similar in both groups (37.5% and 33.3%, p = n.s.). Cuff integrity at follow-up was not predictive of superior scores or strength.
    Conclusion: Surgical treatment of traumatic and non-traumatic RCT yields good clinical results in patients under the age of 50. The etiology of the rotator cuff tear did not significantly affect postoperative outcomes or healing rates. About one third of the patients suffered from a retear postoperatively, however retears were not predictive of inferior outcomes at midterm follow-up.
    Study design: Level III.
    Trial registration: Retrospectively registered.

    Abstract While low-grade acromioclavicular injuries can be managed nonoperatively, high-grade separations may result in persistent pain or functional decline and require surgical intervention. The authors of "Posterior Distal Clavicle Beveling for Chronic Nonincarcerated Type IV Acromioclavicular Separations: Surgical Technique and Early Clinical Outcomes" present a case series reporting convincing results concerning functional outcomes and early return-to-sport rates for this rather rare condition. While this technique seemed to work well in this small series of patients, in our opinion, this procedure should be reserved for use in exceptional cases only.

    Abstract Patient-reported outcomes are, by definition, subjective, and there is consensus that individual patient expectations have a significant effect on the postoperative outcome after shoulder arthroscopy. Most of the outcomes in orthopaedic surgery are measured either in terms of functional scores assessing only one joint or as disease or condition-specific outcomes. As such, there exists a growing interest developing better tools to measure quality-of-life outcome scores as an assessment of overall patient health and satisfaction. Recent research shows that quality-of-life outcome measures correlate with joint-specific and functional outcomes after arthroscopic Bankart repair. We also personally believe that quality-of-life scores should become a standard outcome assessment measurement in orthopaedic surgery because while we perform surgery on the joint, we take care of the whole patient.

    Abstract Background: The purposes of the study were to define the minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) after patello-femoral inlay arthroplasty (PFA) and to identify factors predictive for the achievement of clinically important outcomes (CIOs).
    Methods: A total of 99 patients who underwent PFA between 2009 and 2019 and had a minimum of 2-year postoperative follow-up were enrolled in this retrospective monocentric study. Included patients had a mean age of 44 years (range, 21 to 79). The MCID and PASS were calculated using an anchor-based approach for the visual analog scale (VAS) pain, Western Ontario and McMaster Universities Arthritis Index (WOMAC), and Lysholm patient-reported outcome measures. Factors associated with CIO achievement were determined using multivariable logistic regression analyses.
    Results: The established MCID thresholds for clinical improvement were -2.46 for the VAS pain score, -8.5 for the WOMAC score, and + 25.4 for the Lysholm score. Postoperative scores corresponding to the PASS were <2.55 for the VAS pain score, <14.6 for the WOMAC score, and >52.5 points for the Lysholm score. Preoperative patellar instability and concomitant medial patello-femoral ligament reconstruction were independent positive predictors of reaching both MCID and PASS. Additionally, inferior baseline scores and age were predictive of achieving MCID, whereas superior baseline scores and body mass index were predictive of achieving PASS.
    Conclusion: This study determined the thresholds of MCID and PASS for the VAS pain, WOMAC, and Lysholm scores following PFA implantation at 2-year follow-up. The study demonstrated a predictive role of patient age, body mass index, preoperative patient-reported outcome measure scores, preoperative patellar instability, and concomitant medial patello-femoral ligament reconstruction in the achievement of CIOs.
    Level of evidence: Prognostic Level IV.

    Abstract Rationale and objectives: To determine the diagnostic accuracy and reproducibility of conventional MR imaging (MRI) of the shoulder in evaluating biceps pulley lesions using arthroscopy as the standard of reference.
    Methods: In a retrospective study, MR examinations of 68 patients with arthroscopically proven torn or intact biceps pulley were assessed for the presence of pulley lesions by three radiologists. The following criteria were evaluated: displacement of the long head of the biceps tendon (LHBT) relative to the subscapularis tendon (displacement sign), subluxation/dislocation of the LHBT, the integrity of the superior glenohumeral ligament (SGHL) and the coracohumeral ligament (CHL), lesions of the supraspinatus (SSP) and subscapularis (SSC) tendons adjacent to the rotator interval, presence of biceps tendinopathy and subacromial bursitis.
    Results: There were 42 patients with pulley lesions in the study group. Conventional MR imaging showed an overall sensitivity of 95.2%, 88.1% and 92.9%, a specificity of 61.5%, 73.1%, and 80.8% and an accuracy of 82.4%, 82.4% and 88.2% in the diagnosis of pulley lesions. Interobserver agreement was substantial (multirater k = 0.75). Biceps tendinopathy (97.6%, 95.2%, 97.6%), defects of the SGHL (86.3%, 81.0%, 88.1%) and the displacement sign (88.1%, 81.0%, 85.7%) were the most sensitive diagnostic criteria. Subluxation/dislocation of the LHBT was insensitive (78.6%, 42.9%, 33.3%), but specific (69.2%, 100,0%, 96.2%).
    Conclusion: In the diagnosis of pulley lesions, conventional MR imaging is reproducible and shows high sensitivity and accuracy but moderate specificity.
