BACKGROUND: Few studies have investigated long-term clinical outcomes of a mobile-bearing total ankle arthroplasty (TAA) system. This study analyzed long-term outcomes of TAA using the HINTEGRA prosthesis at a single, non-developer center. METHODS: Primary TAAs were performed on 213 ankles in 194 patients, and 151 consecutive ankles [71%] in 136 patients with a minimum follow-up of 10 years after the primary TAA were included in this study. Clinical results were assessed using a visual analog sc

AIMS: The aim of this study was a quantitative analysis of a surgeon's learning curve for scoliosis surgery and the relationship between the surgeon's experience and post-operative outcomes, which has not been previously well described. PATIENTS AND METHODS: We have investigated the operating time as a function of the number of patients to determine a specific pattern; we analysed factors affecting the operating time and compared intra- and post-operative outcomes. We analysed 47 consecutive pat

BACKGROUND: We compared the radiological and clinical outcomes of mild to moderate and severe hallux valgus (HV) treated with minimally invasive distal metatarsal transverse osteotomy (MITO) performed by a single surgeon. METHODS: Eighty-four patients who underwent MITO between May 2018 and March 2020 were recruited and followed for at least 24 months. The severe group was defined as having a preoperative hallux valgus angle (HVA) >40 degrees or preoperative first-to-second intermetatarsal angle

The incidence of achilles tendon rupture varies by gender, age, and seasonal variation. However, there has been no study as yet linking achilles tendon rupture to daily fluctuations in outdoor temperature. The purpose of this study was to investigate the association between outdoor temperature and achilles tendon rupture using a Korea Meteorological Administration database and a Korean National Health Insurance Service-National Sample Cohort database. Between 2002 and 2015, all instances of achi

Red blood cell distribution width (RDW) is a prognostic factor in various disorders. This study aimed to assess the prognostic value of RDW in patients undergoing amputation for diabetic foot. We retrospectively analyzed data on 415 patients who underwent diabetic foot amputation between January 2009 and January 2019. After establishing an optimal cutoff value of preoperative RDW for all-cause mortality, univariable and multivariable analyses with Cox proportional hazard model for survivorship a

Severe bone defects pose a clinical challenge in total ankle arthroplasty (TAA) and are frequently considered contraindicated. We introduce an innovative approach that utilizes a structural tibial cut autograft to address anterior distal tibia bone defects during TAA. This technique is a viable alternative to employing revision TAA systems or resorting to excessively high tibial cuts. Furthermore, it facilitates achieving favorable sagittal alignment and ensures adequate fixation strength of the

BACKGROUND: Periprosthetic osteolysis after total ankle arthroplasty (TAA) is a substantial problem. Bone grafting may be beneficial in the treatment of large osteolytic cysts; however, the literature regarding the outcomes of bone grafting is limited. This study analyzed the outcomes of autogenous bone grafting performed for the management of periprosthetic osteolysis following TAA. METHODS: We retrospectively reviewed 42 ankles (41 Korean patients) that underwent autogenous bone grafting for p

BACKGROUND: Os subfibulare (OS) is commonly found in patients with chronic lateral ankle instability (CLAI). When performing lateral ligament reconstruction for CLAI, excision of a large OS can cause substantial lateral ligament defects making anatomic repair challenging. This study analyzed clinical and radiologic outcomes among patients who underwent osteosynthesis of the OS for chronic lateral ankle instability and a large OS. METHODS: 28 ankles with CLAI and a large OS (≥10 mm) that underwen

STS sclerotherapy was an effective and safe treatment for patients with lateral malleolar bursitis of the ankle.

Myiasis is the parasitic infestation of the body of a live animal by fly larvae that grow inside the host while feeding on its tissue. Necrotic tissue is a favorable environment for larvae to thrive, which can be seen easily in patients with a diabetic foot. Myiasis in a diabetic foot is rare but is constantly being reported. The common larvae genera causing myiasis are Calliphoridae, Sarcophagidae, and Muscidae. This paper reports a rare case of sarcophaga myiasis in a diabetic foot. To the bes

Research Type: Level 3 - Retrospective cohort study, Case-control study, Meta-analysis of Level 3 studies Introduction/Purpose: Analyses of long-term results after total ankle arthroplasty (TAA) in ankles with preoperative varus deformity with adequate sample sizes remain limited. This study compared the intermediate- to long-term outcomes of TAA in patients with preoperative neutral alignment and moderate to severe varus alignment (≥10°). Methods: A total of 299 consecutive ankles that underwen
