Background: Recurrent anterior glenohumeral instability is a disabling pathology that can be successfully treated by arthroscopic Bankart repair or open Latarjet. However, there is a paucity of studies comparing the postoperative recovery. The purpose of this study is to evaluate the postoperative pain and functional recovery following arthroscopic Bankart versus open Latarjet., Methods: This is a retrospective analysis of a multicenter prospective outcomes registry database. Postoperative recovery outcomes of either a primary or revision arthroscopic Bankart and open Latarjet procedures were compared. A minimum of 1-year follow-up was required. Outcomes measures included pain visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) function score, ASES index score, and single assessment numeric evaluation (SANE) score. Overall, 787 patients underwent primary arthroscopic Bankart, 36 underwent revision arthroscopic Bankart and 75 underwent an open Latarjet procedure., Results: When compared to primary arthroscopic Bankart, open Latarjet demonstrated significantly lower VAS scores at 6 weeks (p = 0.03), 3 months (p = 0.01), and 2 years (p < 0.05). Medium-term outcomes for ASES scores and SANE score, at 1 and 2 years showed no difference. Latarjet demonstrated significantly lower (p < 0.05) preoperative early postoperative VAS pain scores with no difference at 1 year or 2 years when compared to primary Bankart. There was no difference in ASES function or index between Bankart and Latarjet. Revision Bankart provided inferior outcomes for VAS, ASES function, and ASES index when compared to primary Bankart and Latarjet at 1 year and 2 years., Conclusions: Primary arthroscopic Bankart repair and open Latarjet provided nearly equivalent improvements in pain (VAS) and functional outcomes (ASES, SANE, VR-12) during the early recovery phase (2 years). This study supports the use of either procedure in the primary treatment of anterior glenohumeral instability. Revision arthroscopic Bankart repair demonstrated deteriorating outcomes at 1 and 2 years postoperatively., (© 2022.

Background: The management of massive posterosuperior rotator cuff tears is controversial, with no gold standard. Two recently developed techniques that have shown promising initial results include arthroscopic superior capsular reconstruction (SCR) and tendon transfers (latissimus or lower trapezius). However, there remains a scarcity of studies examining each procedure's early postoperative clinical outcomes individually or in comparison to each other. The purpose of this study is to compare the early postoperative recovery outcomes of tendon transfers (TTs) to SCR., Methods: Using the surgical outcomes system global database (Arthrex Inc.), we assessed the postoperative recovery outcomes for all patients who had outcomes recorded at least 6 months after SCR or TT. The time points analyzed included preoperative and postoperative (2 weeks, 6 weeks, 3 months, 6 months, 1 year, 2 years). The outcomes analyzed included pain visual analog scale (VAS) score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, VR-12 physical, and Single Assessment Numeric Evaluation (SANE)., Results: Overall, 163 patients underwent SCR and 24 arthroscopically assisted TT. The mean age for SCR and TT was 60 and 56 years, respectively. Postoperative recovery curves demonstrate that both procedures produced improved outcomes at each postoperative time point compared to preoperative. The pain and functional outcomes measures, including VAS, ASES, SANE, and VR-12 physical, were comparable for TT and SCRs, with similar recovery curves between the 2 techniques. Ultimately at 2 years postoperatively, there were no significant differences between the 2 techniques., Conclusions: Analysis of the early outcomes associated with arthroscopic treatment of massive posterosuperior rotator cuff tears demonstrated that the arthroscopically assisted tendon transfers and arthroscopic superior capsular reconstruction had similar pain and functional outcomes throughout the 2-year postoperative recovery period. Overall, the process of recovery appears equivalent between the 2 techniques. Future studies are needed to assess the outcomes of each technique and specific indications in an attempt to delineate an algorithm for the treatment of irreparable rotator cuff tears., (Copyright © 2022 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: To examine the accuracy, sensitivity, and specificity of a minimally invasive needle arthroscopy device and magnetic resonance imaging (MRI) compared with diagnostic arthroscopy, the gold standard in diagnosing intra-articular shoulder pathologies., Methods: This was a prospective, blinded clinical trial over 6 months on 50 patients with shoulder pathology requiring arthroscopy. Patients were eligible if they had an MRI and consented for surgical arthroscopy. Patients were excluded if they didn't consent. Each underwent a clinical evaluation, MRI, needle arthroscopy, and surgical arthroscopy. Videos and images were blindly reviewed postoperatively. Analysis included sensitivity, specificity, positive predictive value (PPV), negative predictive value, Cohen's kappa agreement coefficient, and the McNemar test., Results: Needle arthroscopy had similar accuracy to MRI in diagnosing intra-articular shoulder pathologies when both were compared with the gold standard of diagnostic arthroscopy. It had high specificities and PPV for certain rotator cuff tears, biceps pathology, and anterior labral tears. When compared with the gold standard, specificity of needle arthroscopy for diagnosing rotator cuff tear and cartilage lesions was 1.00 and 0.97 and 0.72 and 0.86 for MRIs, respectively. Sensitivity of needle arthroscopy for rotator cuff and cartilage lesions was 0.89 and 0.74, respectively, lower than MRI. For most intra-articular pathologies, needle arthroscopy was at least equally accurate to MRI at diagnosing intra-articular shoulder pathologies, with similar or high kappa statistics when correlated with surgical arthroscopic findings., Conclusions: Needle arthroscopy is a promising diagnostic modality for intra-articular shoulder pathologies. It had comparable accuracy with MRI for diagnosing articular cartilage, labrum, rotator cuff, and biceps pathology. Across all pathologies, needle arthroscopy had better ability to "rule in" a diagnosis (high specificities and PPV), but slightly worse ability to "rule out" a diagnosis (lower sensitivities and negative predictive value) compared with MRI., Level of Evidence: Level II, Development of diagnostic criteria on consecutive patients (with universally applied reference "gold" standard)., (Copyright © 2021 Arthroscopy Association of North America.

Background: Bone grafting during primary reverse shoulder arthroplasty (RSA) is a technique used to restore poor glenoid bone, increase lateralization, and restore abnormal inclination or version. The purpose of this article is to analyze early outcomes of bone grafting during RSA, assessing the influence of technical and patient considerations., Methods: In a 4.5-year time period, 137 RSAs with glenoid bone grafting were performed with a minimum 3 months' follow-up. The mean follow-up was 17 months (range, 3-38). The mean age was 71 years (range, 45-89), and body mass index was 28 (range, 19-44). The source of the autografts were humeral head (n = 113) and iliac crest autograft (ICBG; n = 24). The humeral components included 84 onlay and 53 inlay designs., Results: Overall, there were 16 complications (12%), of which 6 were major (5%) (3 graft nonunions and 3 infections) and 10 minor (8%) (1 carpal tunnel syndrome and 9 transient axillary neuropraxias). Of the 9 axillary neuropraxias, 8 resolved by the most recent follow-up, whereas 1 patient was lost to follow-up. There were 4 reoperations (3%): 2 for glenoid baseplate loosening, 1 for severe notching associated with severe glenoid bone loss, and 1 for deep periprosthetic infection. One additional patient had a baseplate failure and is undergoing further treatment. There was no difference in the occurrence of graft nonunions, revision surgery, or glenoid component loosening when comparing type of graft or humeral component used. There was an association of revision surgery (P = .02) with ICBG and older age at the time of surgery (P = .02) and an association of transient neuroapraxia with onlay humeral components (P = .01) and workers' compensation cases (P = .04)., Conclusions: There is a high union rate and low complication rate after bone grafting of the glenoid performed with RSA. Transient neuropraxias are the most frequent complication, but the majority resolve within the first postoperative year. These early findings can serve as the basis for future long-term, comprehensive analysis of complications and outcomes after bone grafting during RSA., (Copyright © 2020 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: The purpose of this study is to analyze the outcomes of open and arthroscopic capsular release following total shoulder arthroplasty., Methods: Over 15 years, 19 patients experienced persistent shoulder stiffness after anatomic total shoulder arthroplasty refractory to nonoperative treatment, requiring either open (n = 5) or arthroscopic (n = 14) capsular release. There were seven (39%) patients who had a prior diagnosis of stiffness before the primary arthroplasty., Results: At a follow-up of 2.3 years (1-5.5), there were changes in range of motion, including forward flexion (77°-117°), abduction (49°-98°), external rotation (9°-19°), internal rotation at 0° (Sacrum to L1), and pain (4.1-2.3) scores (p < 0.01). There were seven (37%) patients that required a reoperation following the initial capsular release. The survival-free of reoperation at 2 and 5 years was 76% and 53%, respectively, while the survival-free of revision surgery at 2 and 5 years was 83%. Furthermore, three (16%) patients required a repeat capsular release. Overall, there were 11 (58%) complications, including stiffness (n = 9), infection (n = 1), subscapularis rupture (n = 2), glenoid loosening (n = 3), and pain with weakness requiring reoperation (n = 1)., Conclusions: Shoulder stiffness after total shoulder arthroplasty is a very difficult pathology to treat, with high rates of complications and reoperations after capsular release. Overall, in patients that do not develop glenoid loosening, capsular release does improve the patient's pain and shoulder motion. Furthermore, when patients develop stiffness, it is critical to rule out other etiologies, such as glenoid loosening, prior to proceeding with capsular release., Level of Evidence Iv: Retrospective case series.

Background: Neurologic dysfunction is a known complication after the open Latarjet procedure. Although the reported clinical incidence is variable, a prior neuromonitoring study demonstrated a significant incidence of nerve dysfunction during surgery, presumably from nerve stretch. We aimed to determine whether a nerve stretch-reduction protocol reduced the incidence of neurologic injury after the open Latarjet procedure., Methods: In a nonrandomized study, 38 patients (group 1) who underwent surgery before our neuromonitoring study were compared with 48 patients (group 2) who underwent surgery after this study. Follow-up was at least 3 months or until documented resolution of nerve dysfunction., Results: There were no significant demographic differences between the groups. In group 1, there were 7 nerve injuries, of which all but 2 recovered. In group 2, there were 3 nerve injuries, of which all but 1 recovered. The overall incidence of nerve injury was 18.4% (group 1) vs. 6.3% (group 2); however, the incidence of permanent motor dysfunction was 5.3% (group 1) vs. 2.1% (group 2). These differences were not significant, likely due to the small number of patients included., Conclusions: We observed a reduction of nerve injury with the implementation of a nerve stretch-reduction protocol during the Latarjet procedure; however, we could not demonstrate statistical significance. This trend represents an important finding that modification of surgical technique can reduce the incidence of nerve injury with the Latarjet procedure., (Copyright © 2018 Journal of Shoulder and Elbow Surgery Board of Trustees.
