Introduction: Pigmented villonodular synovitis (PVNS) after replacement arthroplasty is a potential cause of postoperative pain and hemarthrosis. The disease is difficult to diagnose after arthroplasty, since magnetic resonance imaging (MRI) appearances are subject to metal artifact making them less than ideal. Case Report: A case of a 61­year­old woman with PVNS after unicompartmental knee art...

BACKGROUND Knee size and body size differ in Asians compared with Caucasians. Nevertheless, many total knee arthroplasty (TKA) prostheses used worldwide are made for Western Caucasian subjects. As a result, an Asian's knee might not fit these prostheses. We studied the Flexible Nichidai Knee (FNK) system, a new model of TKA for Asian patients. The purpose of this report is to investigate the ou...

Knee pain is a common presenting complaint with many possible causes. An awareness of certain patterns can help the family physician identify the underlying cause more efficiently. Teenage girls and young women are more likely to have patellar tracking problems such as patellar subluxation and patellofemoral pain syndrome, whereas teenage boys and young men are more likely to have knee extensor...

Abstract Background Hemarthrosis after anterior cruciate ligament (ACL) reconstruction can create many adverse joint effects. Tranexamic acid (TXA) be used to minimize hemarthrosis and associated pain ACL reconstruction. We aimed compare the efficacies of intravenous (IV) administration intra-articular (IA) injection TXA during for reducing postoperative hemarthrosis. Methods A total 120 patien...

INTRODUCTION Sleeve fractures of the patella are rare fractures that only occur in children. The diagnosis is difficult both clinically and radiologically since the distal bony fragment may be too small to be detectable by radiography. A high-riding patella and hemarthrosis are important signs of sleeve fractures. CASE REPORT A 12-year-old boy was admitted to the emergency room after having f...

Four patients with hemarthrosis of the knee, synovial rupture, and ecchymoses are reported. The patients presented with calf pain and swelling and large ecchymoses, which eventually extended to the ankle as a crescent about one or both malleoli. Appreciation of this physical sign, which appears to be characteristic for the hemorrhagic subset of synovial rupture, should alert the physician to th...

BACKGROUND/AIM Ankaferd blood stopper (ABS) is a mixture of certain ratios of 5 different plant roots (Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica). The aim of this study is to evaluate the histopathological effects of ABS on articular cartilage in vitro. MATERIALS AND METHODS Twenty-one albino Sprague Dawley rats were randomly allocated to 3 gr...

BACKGROUND Persistent pain after total knee arthroplasty (TKA) is dissatisfying to the patient and frustrating to the surgeon. The purpose of this study is to evaluate the aseptic causes and clinical course of intractable pain following TKA. METHODS Of the total 2,534 cases of primary TKA reviewed, 178 cases were classified as having aseptic persistent pain that was not resolved within 1 year...
