PURPOSE: To evaluate the long-term clinical results and survivorship of unicompartmental knee arthroplasty (UKA) in patients younger than 60 years of age. MATERIALS AND METHODS: One hundred and six cases of medial UKA with a minimum follow-up of 10 years were selected for this study. There were 80 patients and the preoperative diagnosis was osteoarthritis in all cases. The mean age of the patients was 54.2 years and the mean duration of follow-up was 12.1 years. Clinical assessments were perform

Background: Only a few studies have reported on the risk factors for non-union after open reduction and internal fixation (ORIF) in distal humerus fractures. Methods: We retrospectively reviewed 155 patients who underwent ORIF for distal humerus fractures from January 2008 to June 2020. Various patient factors, including body mass index (BMI), diabetes mellitus (DM), and combined fracture, as well as surgical factors, including fixation methods (e.g., orthogonal plate/parallel plate/single plate

BACKGROUND: Open reduction and plate fixation are the preferred treatment options for most distal humerus fractures in adults. However, it is often challenging for orthopedic surgeons because of the complex anatomy and the difficulty in achieving stable fixation. This multicenter study aimed to analyze the complication types and rates of patients with distal humerus fractures treated with open reduction and plate fixation, and compare the results with those found in the literature. In addition,

BACKGROUND: Arthroscopic Bankart repair is the most common procedure in patients with anterior shoulder instability. Various repair techniques using suture anchors have been used to improve the strength of fixation and surgical outcomes in arthroscopic Bankart surgery. However, evidence regarding which method is superior is lacking. This systematic review and meta-analysis study was designed to compare the biomechanical results of simple versus horizontal mattress versus double-row mattress for

BACKGROUND: Instep flaps are commonly used for the reconstruction of weight-bearing areas of the foot. However, in cases of large defects or damage to the instep area, non-instep flaps such as reverse sural flaps (RSF) or free anterolateral thigh flaps (ALTF) can be employed. Previous studies have primarily focused on heel reconstruction when comparing different flaps, without considering the forefoot. This study aims to verify the clinical outcomes of these flaps and determine the appropriate d

The prognosis of NC depended on the causes. EH was the best and unknown was the worst prognostic factor. Revision should be performed as soon as possible for a better prognosis.

BACKGROUND AND AIM: Radial shortening after distal radius fracture causes ulnar impaction, and a mild reduction loss of radial height occurs even after volar locking plate fixation. This study aimed to determine whether preoperative ulnar-sided sclerosis affects clinical outcomes after volar locking plate fixation for distal radius fracture (DRF). METHOD: Among 369 patients who underwent volar locking plate fixation for DRF, 18 with preoperative ulnar-sided sclerosis of the lunate were included

Introduction Arthroplasties of hip and knee are associated with blood loss, which may lead to adverse patient outcome. Jehovah9s Witnesses do not accept blood transfusion. Performing arthroplasties in Witness patients without transfusion has been a matter of concern. We developed a protocol, which avoids transfusion in arthroplasties of Witness patients, and evaluated the feasibility and safety of the protocol. Materials and Methods Our protocol consisted of subcutaneous administration of 4000 U

BACKGROUND: Mesenchymal stem cells (MSCs) are used in cell therapy to enhance healing in long bone fractures, where nonunion is highly likely to occur. However, only a few studies have been conducted on carriers that should be used for more effective cell delivery. This study compared the use of hydrogel and normal saline as carriers for enhancing fracture healing when injecting MSC in a long bone fracture rat model. METHODS: Wistar rats were classified according to the carrier used for MSC inje
