OBJECTIVE To study surgical techniques for degenerative lumbar scoliosis associated with lumbar stenosis and evaluate their clinical significane. METHODS Thirty-two patients with degenerative lumbar scoliosis associated with spinal stenosis were treated by techniques of posterior lumbar interbody fusion or posterolateral fusion and pedicle screws. There(More)
OBJECTIVE To investigate the change in joint line after knee arthroplasty. METHODS A total of 43 patients had 25 primary cruciate-retaining total knee replacements (Link Gemini MKII) and 25 rotational knee replacements (Link Endo-Model Rotational Knee System) sacrificing collateral ligaments and cruciate ligaments. Lateral radiographs were made both(More)
OBJECTIVE To investigate the etiologies and prevention of patellar instability after total knee arthroplasty (TKA). METHODS From September 1997 to April 2005, 94 patients (105 knees) underwent TKA without patellar resurfacing. All of them were osteoarthritis. Ten patients (14 knees) were performed with Rotation Knee (RK) prostheses. Forty patients were(More)
OBJECTIVE To explore the imaging reasons for periprosthetic femoral fractures during the operation of total hip arthroplasty with anatomic prosthesis. METHODS The fracture group consisted of 7 cases with periprosthetic femoral fracture (PPFF) and the non-fracture group 21 cases without PPFF during the operation of total hip arthroplasty (THA) among the(More)
BACKGROUND Researchers initially proposed the substitution of apoptotic chondrocytes in the superficial cartilage by injecting mesenchymal stem cells (MSCs) intraarticularly. This effect was termed as bio-resurfacing. Little evidence supporting the treatment of osteoarthritis (OA) by the delivery of a MSC suspension exists. The aim of this study was to(More)
