BACKGROUND: Some studies have shown significant functional improvement after rotator cuff (RC) repair in elderly patients. However, few studies have reported the healing potential of RC tears in elderly patients. METHODS: Twenty-five patients aged ≥ 75 years who underwent RC repair were enrolled. The mean age at the time of surgery was 78.3 years (range, 75 to 88 years) while the mean follow-up was 36.3 months (range, 18 to 114 months). We evaluated clinical and structural outcomes after RC repa

BACKGROUND:: Arthroscopic microfracture can effectively treat osteochondral lesions of the talus (OLTs). However, very few studies have reported on symptomatic improvement duration and time when symptomatic improvement ceases. This study aimed to investigate the clinical outcome changes after arthroscopic microfracture in patients with OLT. METHODS:: Among patients who underwent arthroscopic microfracture for OLT, 70 patients were available for follow-up for more than 3 years. Of these, 6 patien

PURPOSE: To review 437 hips in 404 patients who underwent total hip arthroplasty (THA) or hemiarthroplasty using the Accolade TMZF stem to determine the incidence and risk factors of distal femoral cortical hypertrophy (DFCH). METHODS: Records of 437 hips in 169 men and 235 women aged 26 to 100 (mean, 65.7) years who underwent THA (n=293) or hemiarthroplasty (n=144) using the Accolade TMZF femoral stem by 2 senior surgeons and were followed up for a mean of 54.7 months were reviewed. Clinical ou

PURPOSE: The purpose of the present study was to compare the clinical and radiographic results after TKA using two prostheses with different sagittal patellofemoral design features, including outcomes related to compatibility of the patellofemoral joint. METHODS: The clinical and radiographic results of 81 patients (100 knees) who underwent TKA using the specific prosthesis (group A) were compared with those in a control group who underwent TKA using the other prosthesis (group B). The presence

BACKGROUND: Syndesmosis disruptions in the ankle joint are typically treated with anatomic reduction followed by transfixing screw and/or suture button fixation. The purpose of our study was to analyze the effects of the removal of transfixing screws on syndesmosis integrity using plain radiographs and computed tomography (CT) scans. METHODS: Twenty-nine cases (29 patients) who had been treated with transfixing screw fixation for syndesmosis disruptions were studied prospectively. Plain radiogra

PURPOSE: The purpose of the present study was to compare the change in tibial posterior slope angle (PSA) between patients treated via computer-assisted and conventional closed-wedge high tibial osteotomy (CWHTO). It was hypothesized that a decrease in the PSA would be less in the computer-assisted group than in the conventional group. METHODS: Data on a total of 75 computer-assisted CWHTOs (60 patients) and 75 conventional CWHTOs (49 patients) were retrospectively compared using matched pair an

PURPOSE: This study sought to confirm whether traditional open Broström-Gould repair and arthroscopic Broström-Gould repair for chronic ankle instability (CAI) would produce comparable radiological and clinical outcomes in high-demand patients. METHODS: This retrospective case-cohort study included high-demand patients, as determined by a pre-injury Tegner Activity Level ≥ 6, who underwent Broström-Gould repair and were followed up for ≥ 2 years. Patients were divided into the arthroscopic Brost
