Based on the results of this study, PSO is considered a reliable and relatively safe procedure for the correction of fixed sagittal imbalance with multiple etiologies.

BACKGROUND: The authors noticed that ankle joint osteoarthritis was not uncommon when lower extremity malalignment, such as a knee varus deformity, was present as a result of severe osteoarthritis of the knee. The purpose of this study was to analyze radiologic changes of the ankle joint after total knee arthroplasty. METHODS: This study included 142 cases in 110 patients who underwent total knee arthroplasty and were followed for at least 3 years. The varus knee group included 128 cases and the

BACKGROUND: The purpose of this study was to assess the feasibility of inferior extensor retinaculum (IER) reinforcement and analyze differences in clinical and radiographic outcomes based on whether or not IER reinforcement was performed in modified Broström procedures. METHODS: Forty-one patients (41 ankles) who underwent ankle reconstruction with either a Broström procedure or modified Broström with IER reinforcement were included in this prospective study. During Broström procedures, feasibi

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

Background: Total ankle arthroplasty (TAA) can result in excellent outcomes in patients with end-stage arthritis, but most patients with end-stage hemophilic ankle arthropathy (ESHAA) still undergo ankle arthrodesis (AA). The purpose of this study was to analyze clinical and radiological results of TAA and AA for ESHAA. Methods: A total of 29 cases (16 TAAs and 13 AAs) of painful ESHAA were included. For clinical outcome evaluation, visual analog scale (VAS) for pain, Foot Function Index (FFI),

PURPOSE: Arthroscopic all-inside anterior talofibular ligament (ATFL) repair is a common surgical technique for chronic ankle instability (CAI), and the condition of the ATFL remnants is associated with its reparability. ATFL reparability can affect the clinical course, but the relationship between magnetic resonance imaging (MRI) findings and the intraoperative ATFL reparability is still unclear. The purpose of this study was to investigate the relationship between ATFL signal intensities accor

Background: In patients with end-stage varus ankle osteoarthritis (OA), hindfoot varus malalignment resulting from the varus deformity of the ankle joint is common. Although total ankle arthroplasty (TAA) performed to correct varus deformity of the ankle joint has the effect of correcting hindfoot alignment, no reports to date have described how much hindfoot alignment correction can be achieved. The purpose of this study was to identify correlation between ankle deformity correction and hindfoo

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: 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

BACKGROUND: The diagnosis of clinically important instability following isolated supination-external rotation (SER) distal fibular fractures is a challenge. The purpose of this study was to investigate the accuracy of clinical findings including medial tenderness, swelling, and ecchymosis, combined with the gravity stress test and magnetic resonance imaging (MRI), in the assessment of ankle mortise stability in association with isolated SER-type lateral malleolar fractures. The external rotation

Involvement of the growth plate by a tumor or an injured growth plate during surgical procedures causes a discrepancy in the limb length. To address this problem,distraction osteogenesis is a well-established procedure for the treatment of defect and leg length discrepancy inviable bone tissues. We present the lengthening of an intercalary allograft combined with a vascularized fibular graft after reconstruction of osteosarcoma in the femoral metaphysis of a 10-year-old boy. The ability to lengt
