Background and Objectives: Postoperative delirium (PODil) is a cognitive condition characterized by sudden fluctuations in consciousness and orientation after surgery. PODil following total knee arthroplasty (TKA) is associated with prolonged hospital stays and increased morbidity. Therefore, prevention of PODil is particularly important. Life’s Simple 7 score, published by the American Heart Association, is a new measure of cardiovascular health (CVH). Better CVH is associated with a lower risk of cognitive impairment. Hence, this study aimed to determine whether Life’s Simple 7 score is associated with PODil following TKA. Materials and Methods: This retrospective study included 973 patients who underwent TKA between January 2015 and January 2020. Patients were divided into two groups (group I: delirium group, n = 60; group II: non-delirium group, n = 913). Demographic data, use of analgesics, surgical factors, underlying diseases, laboratory results, and Life’s Simple 7 score were evaluated. Results: Significant differences were observed between the two groups for Parkinson’s disease, intraoperative hypotension, preoperative duloxetine administration, and Life’s Simple 7 score. In the receiver operating characteristic (ROC) curve analysis, the optimal cut-off value for Life’s Simple 7 score was determined to be 8 at the maximal Youden index, with an area under the curve (AUC) of 0.82, a sensitivity of 0.92, and a specificity of 0.58. Conclusions: Lower Life’s Simple 7 score is an independent risk factor for the incidence of PODil after TKA. Given its ease of measurement, Life’s Simple 7 score may be a useful measure for predicting PODil and will aid in preoperative risk assessment and post-operative patient management.

The elbow is a complex joint with a wide range of motion and many functions. Its bony structure, composed of the humerus, radius, and ulna, and various muscles and ligaments work as a functional unit. One or multiple elbow joint components can cause pain and functional deficits; therefore, determining the underlying etiology of elbow pain can be difficult. Accordingly, this paper discusses the causes of common conditions that can lead to elbow pain and their respective diagnosis and treatment options.

Background and Objectives: Unstable distal clavicle fractures (Neer type II) have a relatively high risk of nonunion and often require operative fixation. Hook plates are widely used, particularly when the distal fragment is small or comminuted, because they provide strong vertical stability. However, hook plates are associated with subacromial irritation, acromial wear, and the need for routine implant removal. Distal locking plates with supplementary cerclage augmentation can achieve fixation without subacromial impingement and may reduce implant-related complications. This study aimed to compare clinical and radiologic outcomes of hook plates versus locking plates with or without cerclage augmentation for Neer type II distal clavicle fractures. Materials and Methods: In this single-center retrospective cohort, adult patients with Neer type II distal clavicle fractures who underwent open reduction and internal fixation between March 2021 and August 2022, with ≥6 months of follow-up, were reviewed. Patients were allocated into two groups according to implant: hook plate (Group 1, n = 16) and distal locking plate with or without cerclage augmentation (Group 2, n = 26). Primary outcomes were complication rate, radiographic union, and shoulder range of motion (ROM). Secondary outcomes included pain (PVAS) and functional scores (SANE, ASES, Constant, UCLA). Results: Forty-two patients were analyzed (locking n = 26, hook n = 16). Groups were comparable in age (51.3 ± 16.0 vs. 54.4 ± 17.1 years), follow-up (7.0 ± 4.0 vs. 8.4 ± 4.3 months), sex distribution, smoking status, and mechanism of injury. Radiographic union was achieved in 24/26 (92.3%) patients in the locking group and 14/16 (87.5%) in the hook group; two cases of nonunion or reduction failure occurred in each group (p = 0.612). Final patient-reported outcomes and ROM were similar between groups (e.g., ASES 68.2 ± 15.5 vs. 64.4 ± 18.3, Constant 57.3 ± 9.5 vs. 44.9 ± 20.5; all p > 0.05). Forward flexion tended to be higher in the locking group (138.9 ± 28.0° vs. 113.3 ± 36.7°, p = 0.182), although without statistical significance. No deep infection, peri-implant fracture, or hardware failure requiring unplanned revision was observed. Subacromial wear was identified in four patients (25%) in the hook plate group, whereas no such change was observed in the locking group. Conclusions: Both hook plates and distal locking plates (±cerclage) provided high union rates and satisfactory functional outcomes for Neer type II distal clavicle fractures. However, hook plates were associated with subacromial wear, whereas locking plate constructs avoided subacromial complications. When distal fragment purchase is feasible—or can be supplemented with cerclage augmentation—locking plate fixation represents a reliable first-line option, with hook plates reserved for cases with minimal distal bone stock or complex comminution.

Patch augmentation with acellular dermal matrix (ADM) allograft is increasingly recognized as an effective method to enhance healing rates following rotator cuff repair in cases of massive rotator cuff tears. However, there is still variability in how patch augmentation is performed. In this study, the authors present a patch augmentation using an ADM allograft into the triple row‐suture bridge technique for treatment of large to massive rotator cuff tear. This method, characterized by knotting the medial row sutures over the ADM allograft, is designed to enhance healing by increasing the contact area among the graft, the rotator cuff tendon, and the footprint, while reducing direct pressure on the tendon.
