The purpose of this study was to evaluate the hypothesis that a less invasive (LIS) surgical technique using a navigation system would promote rapid recovery and improve alignment compared with conventional technique in total knee arthroplasty (TKA). This study compared 49 navigation-assisted LIS TKAs with 53 conventionally performed TKAs using a medial(More)
The purpose of this study was to compare the range of motion (ROM) of conventional total knee arthroplasty (TKA) using high-flexion, posterior cruciate ligament (PCL) stabilized prostheses and the ROM of conventional knee arthroplasty using navigation-assisted TKA, with mobile-bearing, cruciate ligament-retaining knees. Fifty conventional TKAs with(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)
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 authors investigated the hypothesis that navigation system-assisted minimally invasive unicompartmental knee arthroplasty (NA-MIS UKA) produces better short-term clinical results than MIS UKA without a navigation system. After a minimum 2-year follow-up, short-term functional results and component alignment accuracies of 31 knees that underwent NA-MIS(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)
The authors evaluated the relationships between preoperative and postoperative kinematics in 50 osteoarthritic knees scheduled for cruciate retaining total knee arthroplasty with regards to posterior femoral roll back and external femoral rotation using a navigation system from 10° to 120° of knee flexion. Although posterior femoral roll back was(More)
BACKGROUND Range of motion after a total knee arthroplasty is an important indicator of clinical outcome. Recently, a high-flexion posterior cruciate ligament-retaining knee prosthesis was designed to allow greater flexion after total knee arthroplasty. The purpose of this study was to compare range of motion and functional outcomes in patients who received(More)
BACKGROUND The intent of double-bundle anterior cruciate ligament reconstruction is to reproduce the normal anterior cruciate ligament anatomy and improve knee joint rotational stability. However, no consensus has been reached on the advantages of this technique over the single-bundle technique. HYPOTHESIS We hypothesized that double-bundle anterior(More)
