The clinical and radiologic results of a gender-specific total knee arthroplasty design were compared with those of a conventional unisex design in 50 female patients with bilateral osteoarthritis and a minimum follow-up of 2 years. Total knee arthroplasty was performed using a conventional unisex implant in one knee and a gender-specific implant in the(More)
The purpose of this study was to evaluate the intra-operative stability during double-bundle anterior cruciate ligament (ACL) reconstructions (20 knees) using a navigation system and compare the results with those obtained from single-bundle reconstructions (20 knees). After registering the reference points during ACL reconstruction, antero-posterior and(More)
The purpose of this study was to assess, in anterior cruciate ligament (ACL)-injured and -uninjured population, tibial plateau anatomic variables [medial and lateral tibial plateau slopes (MTPS and LTPS) and medial tibial plateau depth (MTPD)] on conventional magnetic resonance imaging (MRI) using a novel combined method and to determine whether these(More)
We compared the incidence and severity of complications during and after closing- and opening-wedge high tibial osteotomy used for the treatment of varus arthritis of the knee, and identified the risk factors associated with the development of complications. In total, 104 patients underwent laterally based closing-wedge and 90 medial opening-wedge high(More)
Total hip arthroplasty (THA) has been the most common surgery performed for complications of bipolar arthroplasty. We wanted to evaluate functional results and complications after conversion of bipolar hemiarthroplasty to THA in 25 patients followed for an average of 7.2 years. Indications for conversion included acetabular erosion with well-fixed femoral(More)
We report the results of a primary total hip arthroplasty (THA) in 7 patients with advanced active tuberculous arthritis of the hip and had lost the chance of preserving the hip without replacement surgery. Tuberculosis was confirmed in all cases by the culture or histological examination. All patients were treated with primary THA followed by(More)
We studied 58 knees that underwent anterior cruciate ligament (ACL) reconstruction using a patella tendon autograft. The mean age at reconstruction was 30.4 (18–58) years, and the average follow-up was 11.2 (8.6–13.8) years. The presence of osteoarthritis was assessed radiographically using Kellgren and Lawrence’s classification. Osteoarthritis was detected(More)
BACKGROUND Anatomic double-bundle reconstruction has been thought to better simulate the anterior cruciate ligament anatomy. It is, however, a technically challenging procedure, associated with longer operation time and higher cost. HYPOTHESIS Double-bundle anterior cruciate ligament reconstruction using a single femoral and tibial tunnel can closely(More)
This study was undertaken to compare the clinical and radiological outcomes achieved using total knee arthroplasty (TKA) with and without a navigation system. This study included 43 TKAs performed with a navigation system and 42 TKAs without a navigation system with a minimum two-year follow-up. We compared clinical outcomes including range of motion,(More)
The amount of anteroposterior laxity required for a good range of movement and knee function in a cruciate-retaining total knee replacement (TKR) continues to be debated. We undertook a retrospective study to evaluate the effects of anteroposterior laxity on the range of movement and knee function in 55 patients following the e-motion cruciate-retaining TKR(More)
