Background: The relationship between osteoporosis and rotator cuff tears has been reported previously. However, the treatment rate of osteoporosis in individuals with rotator cuff tear is still unknown. The aim of this study was to investigate the prevalence and treatment rate of osteoporosis in individuals with rotator cuff tears. Methods: In this cross-sectional study, we enrolled 207 participants. Participants underwent comprehensive assessments, including shoulder ultrasonographic examinations and quantitative ultrasound measurements for bone status evaluation. Osteoporosis diagnosis was predicated on a calcaneus ultrasound bone densitometry, and the cutoff value was set as a T score of −1.455, with reference to a previous report. Results: One hundred fifty-six participants were classified as individuals without rotator cuff tears (group A), and 51 participants were classified as those with (group B). The mean age in group A was significantly lower than that in group B (63 ± 10 vs. 68 ± 9, respectively; P = .003). In terms of the T score examined by quantitative ultrasound, the mean T score in group A was significantly higher than that in group B (−1.4 ± 1.3 vs. −1.9 ± 1.6, respectively; P = .0412). The percentage of subjects with a T score of −1.455 or less in group B was 60.8% (31/51). The proportion of subjects with a T score of −1.455 or less undergoing osteoporosis treatment was 14.5% (12/83) in group A and 12.9% (4/27) in group B, showing no significant difference. Conclusions: Participants with a rotator cuff tear had relatively high prevalence of osteoporosis. Among those with both a rotator cuff tear and osteoporosis, the proportion receiving osteoporosis treatment was l2.9%, a very low rate.

Background: This study aimed to examine the clinical outcomes of double-bundle (DB) anterior cruciate ligament (ACL) reconstruction in patients aged ≥60 years. Methods: Anatomical DB-ACL reconstruction using hamstring tendon autografts was performed in 13 patients aged ≥60 years at our institution between June 2012 and May 2018. The patients included seven men and six women, and the mean age at surgery was 65.0 years (range, 60–73 years). The mean time from injury to surgery was 80.5 months (range, 1–480 months), and the mean follow-up time was 26.2 months (range, 24–42 months). All patients were assessed based on physical examination findings, clinical scores, Kellgren–Lawrence grades preoperatively and at the final postoperative follow-up, intraoperative meniscal or chondral lesions, and perioperative complications. Status of returning to sports for all patients was assessed at the final follow-up. Results: The mean side-to-side differences by arthrometer improved from 4.3 mm (range, 2–8 mm) to 0.9 mm (range, 0–2 mm), and the positive pivot-shift test decreased from 100% to 8%. The mean extensor muscle strength was 93.3% (range, 74–116%) postoperatively. The mean Lysholm score improved from 71.1 (range, 27-85) to 95.2 (range, 89-100). Ten of the 13 patients (77%) returned to their pre-injury level of sports performance, and one patient (8%) returned to sports with less intensity. Intraoperatively, meniscal tears were observed in 10 patients (77%), and chondral lesions >grade 2 were observed in 11 (85%). One patient developed perioperative complications. At the final follow-up, the Kellgren–Lawrence grade worsened in only one patient. No re-injury or infection was observed, and revision surgery was not required for any patients. Conclusions: Anatomical DB-ACL reconstruction could provide satisfactory clinical outcomes and knee function restoration in patients aged ≥60 years. Level of evidence: A retrospective study, case series (IV).

Background: A decrease in the glenoid size after arthroscopic Bankart repair (ABR) was common in shoulders without osseous fragments compared with those with osseous fragments. For cases of chronic recurrent traumatic anterior glenohumeral instability without osseous fragments, we have performed ABR with peeling osteotomy of the anterior glenoid rim (ABRPO) to make an intentional osseous Bankart lesion. The aim of this study was to compare the glenoid morphology after ABRPO with it after simple ABR. Methods: The medical records of patients who underwent arthroscopic stabilization for chronic recurrent traumatic anterior glenohumeral instability were retrospectively reviewed. Patients with an osseous fragment, with revision surgery and without complete data were excluded. Patients were assigned to 1 of 2 groups: Group A, ABR without peeling osteotomy procedure or Group B, with ABRPO procedure. Computed tomography was performed preoperatively and 1 year after surgery. The size of the glenoid bone loss was investigated by the assumed circle method. The following formula was used to calculate the decreased size of the glenoid: (Δ) = (postoperative size of the glenoid bone loss) − (preoperative size of the glenoid bone loss). The size of the glenoid 1 year after surgery was assessed to determine if it had decreased (Δ > 0%) or not decreased (Δ ≤ 0%) relative to the preoperative size. Results: This study evaluated 39 shoulders divided into 2 groups: 27 shoulders in Group A and 12 shoulders in Group B. In Group A, postoperative glenoid bone loss was significantly greater than preoperative glenoid bone loss (7.8 ± 6.2 vs. 5.5 ± 5.3, respectively, P =.02). In Group B, postoperative glenoid bone loss was significantly lower than preoperative glenoid bone loss (5.6 ± 5.4 vs. 8.7 ± 4.0, respectively, P =.02). The P value for the interaction of group (A or B) × time (preoperative or postoperative) was 0.001. The decreased size of the glenoid was significantly larger in Group A than in Group B (2.1 ± 4.2 vs. −3.1 ± 4.5, respectively, P =.001). The rate of shoulders in which the size of the glenoid decreased 1 year after surgery relative to the preoperative size was significantly higher in Group A than in Group B (63% [17/27] vs. 25% [3/2], respectively, P =.04). Conclusions: The study showed that ABRPO preserved the glenoid size better than simple ABR without a peeling osteotomy procedure.
