BACKGROUND Sidestep cutting technique is essential in programmes to prevent anterior cruciate ligament (ACL) injury. A better understanding of how technique affects potentially harmful joint loading may improve prevention programmes. The purpose of this study was to investigate the effect of sidestep cutting technique on maximum knee abduction moments. METHODS Cross-sectional study. Whole-bod...

Background and Aims The knee joint injury in judokas mostly occurs the standing position. This study aims to investigate relationship between kinematic variables of trunk occurrence injuries male judokas. Methods In this study, 15 aged 20-30 years (7 with a history 8 controls) were selected based on inclusion exclusion criteria. Then, after installing markers their body, they asked stand 30-cm ...

The causes of malalignment in total knee arthroplasty can be categorized into three different groups; 1) Errors in bone cuts 2) Errors in implant fixations, and 3) The method of setting down the cutting guides (1). We would like to announce that more several distal femoral valgus cut errors may occur during total knee replacement.

Subject-specific three-dimensional finite element models of the knee joint were created and used to study the effect of the frontal plane tibiofemoral angle on the stress and strain distribution in the knee cartilage during the stance phase of the gait cycle. Knee models of three subjects with different tibiofemoral angle and body weight were created based on magnetic resonance imaging of the k...

OBJECTIVE To evaluate the clinical and radiological results in the surgical treatment of moderate and severe hallux valgus by performing percutaneous double osteotomy. MATERIAL AND METHOD A retrospective study was conducted on 45 feet of 42 patients diagnosed with moderate-severe hallux valgus, operated on in a single centre and by the same surgeon from May 2009 to March 2013. Two patients we...

A retrospective radiographic review was performed of 29 patients (37 feet) who underwent an isolated medial approach for correction of hallux abducto valgus deformity from March 1993 to November 1998. Only those patients who had a traditional Austin-type osteotomy with a reducible first metatarsophalangeal joint and flexible first ray were included in the study. The average follow-up period for...

PURPOSE To identify the effects of using a Ti-Ni shape memory alloy ring shaped bone fixator (SMA-rBF) during the retrograde nailing of supracondylar femoral fractures. MATERIALS AND METHODS The authors reviewed 25 patients with a supracondylar femoral fracture treated by retrograde intramedullary nailing with or without SMA-rBF (group S, 12/25; group N, 13/25). Radiological measurements of a...

A total knee replacement is one of the most successful orthopedic procedures to enable the patient’s return to a normal, active lifestyle. The angle of the mechanical axis depends on the surgeon’s decision, which effects the strain distribution on the femoral bone and may lead to a fracture of the femur . This study evaluated the equivalent total strain on the femoral shaft under daily activiti...
