An arthroscopic technique for the use of mosaicplasty osteochondral grafting in the treatment of femoral condylar articular defects is described. During the procedure, small cylindrical grafts are harvested from the nonweightbearing periphery of the patellofemoral joint and implanted in mosaiclike fashion into the focal cartilage defect of the weightbearing(More)
This article describes a one-step operative technique for the treatment of circumscript cartilage defects of weight-bearing surfaces of the knee. Since 1992, a total of 227 patients were treated using this technique for full-thickness lesions resulting from chondropathy, traumatic chondral defects, and osteochondritis dissecans; the procedure was evaluated(More)
Studying their subject the authors have been found that among the orthopedic surgical interventions the most frequently applied procedure were the alloarthroplasty and the synovectomy. Half of the operations are performed on the hand and the knee. Because of the polyarticular and multilocular characteristic of the disease very often more than one operations(More)
We summarise our experience gained with knee arthroplasties over 18 years. Between 1976 and 1994 1103 knee arthroplaasties (1044 primary cases, 59 revisions) were performed at the Orthopaedic Department of the National Institute of Rheumatology and Physiotherapy in Budapest, Hungary. The diagnoses were osteoarthritis (OA) in 50.9%, rheumatoid arthritis (RA)(More)
In the operative treatment of the knee diseases Guepar prosthesis was used formerly more frequently, presently however only rarely. The frequence of complications and their treatment are many times serious problems. Authors describe one case in which the postoperative supracondylaer fracture necessitated the insertion of a special knee prosthesis.
This paper reports on the global results of the low contact stress knee prosthesis system with mobile weight bearing surfaces. The follow-up result of 918 cemented and 963 cementless knee prostheses was in more than 90 per cent excellent and good 2-8 years after the operation. The ratio of complications connected with the construction decreased to 2.8 per(More)
Biopsy followed by tumour removal and replacement by autologous bone tumour at the distal end of the femur were performed. Histologically, the tumour proved to be benign. Three years later progression was observed and epiphyseodiaphyseal resection was made because of on excessive tumour. Histology revealed a fibrosarcoma. Consolidation was hindered by(More)
