Orthopedics | The COVID-19 pandemic has had a strong impact on the care of orthopedic patients. This impact has been particularly difficult in New York State, which experienced the largest number of COVID-19 cases and led to a state- mandated pause on all elective surgeries. As a result, physical and occupational therapists became the principal providers of care and had to adjust their workflow to ensure

Rotator cuff tears as a consequence of shoulder instability, which are uncommon among patients younger than 40 years, have been found to be more prevalent in active duty service members in this age group. As a result, this population provides a unique opportunity to study concurrent arthroscopic treatment of rotator cuff and inferior labrum tears in young, active patients, a topic that has not been studied extensively. The goal of this study was to report clinical outcomes of rotator cuff and inferior labral tears managed concurrently with all-arthroscopic repair for military patients younger than 40 years. Data were collected prospectively from 30 arthroscopic rotator cuff repair procedures with concurrent inferior labral repair performed on 29 individual military patients younger than 40 years (mean, 33.5 years; range, 21-39 years) and retrospectively analyzed. Pre-and postoperative evaluations conducted during a minimum 2-year followup period (mean, 35 months; range, 24-68 months) included visual analog scale (VAS) score, Subjective Shoulder Value (SSV), American Shoulder and Elbow Surgeons (ASES) shoulder score, and range of motion. Mean VAS score improved from 7.63 +/- 1.85 to 1.00 +/- 1.44 (P<.0001). Mean SSV improved from 54.83 +/- 17.10 to 90.83 +/- 9.75 (P<.0001). Mean ASES shoulder score improved from 45.37 +/- 12.99 to 90.43 +/- 10.67 (P<.0001). No significant improvement was found in range of motion; however, improved mean measurements were consistently noted in all directions. Complications (10%; 3 of 30) included 1 re-tear of the rotator cuff repair and 2 postoperative frozen shoulders. Arthroscopic repair of rotator cuff tears with concurrent repair of inferior labral tear in active patients younger than 40 years produced excellent patient outcomes, with high rates of return to preoperative level of recreational and military job activity and low risk of complications.

Hill‐Sachs lesions are a common finding in patients with glenohumeral instability. There have been numerous methods described for addressing Hill‐Sachs deformity. One popular method includes transferring a portion of the infraspinatus muscle into the posterior‐superior defect (remplissage) to prevent the lesion from engaging and the resultant instability. We present a method of arthroscopic remplissage whereby the lesion is addressed through transtendinous insertion of arthroscopic anchors. Once 2 anchors have been inserted, 1 limb of each suture is tied to the other anchor, the so‐called pulley repair technique. This can be performed either under direct visualization in the subacromial space or blindly while the surgeon is viewing from the articular side. Once both limbs have been tied, the infraspinatus tendon nicely spans the defect, and there has been minimal morbidity to the tendon itself. We have found this method to be useful for addressing a large Hill‐Sachs deformity. Technique Video: video See video under supplementary data.

Background: Given the rising prevalence of obesity, the number of patients with obesity undergoing arthroscopic rotator cuff repair (RCR) will likely increase; however, there have been mixed results in the existing literature with regard to the effect of elevated body mass index (BMI) on functional outcomes and complications. Methods: The patient-reported outcome measures included the visual analog scale (VAS) pain score, the American Shoulder and Elbow Surgeons (ASES) score, range of motion, and adverse events. Results: Fourteen studies (118,331 patients) were included. There were significant decreases in VAS pain scores for both patients with obesity (mean difference, −3.8 [95% confidence interval (CI), −3.9 to −3.7]; p < 0.001) and patients without obesity (mean difference, −3.2 [95% CI, −3.3 to −3.1]; p < 0.001). There were also significant increases in ASES scores for both patients with obesity (mean difference, 24.3 [95% CI, 22.5 to 26.1]; p < 0.001) and patients without obesity (mean difference, 24.3 [95% CI, 21.4 to 26.0]; p < 0.001). There were also significant increases in ASES scores for both patients with obesity (mean difference, 24.3 [95% CI, 22.5 to 26.1]; p < 0.001) and patients without obesity (mean difference, 24.3 [95% CI, 21.4 to 26.0]; p < 0.001). However, there were no significant differences in final VAS pain scores, ASES scores, or range of motion between the groups. The mean rates of complications were higher among patients with obesity (1.2% ± 1.7%) than among patients without obesity (0.59% ± 0.11%) (p < 0.0001), and the mean rates of postoperative admissions were also higher among patients with obesity (5.9%) than patients without obesity (3.7%) (p < 0.0001). Although the mean rates of reoperation were similar between groups (5.2% ± 2.8% compared with 5.2% ± 4.2%), the meta-analysis revealed lower odds of reoperation in patients without obesity (odds ratio [OR], 0.76 [95% CI, 0.71 to 0.82]). Conclusions: No significant or clinically important differences in postoperative pain, ASES scores, or range of motion were found between patients with and without obesity following arthroscopic RCR. However, populations with obesity had higher rates of complications, postoperative admissions, and reoperation following arthroscopic RCR. Level of Evidence: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.
