title: The Marmor knee prosthesis: long term results in 135 cases.
abstract: The authors report the results of clinical and radiological follow up examinations carried out between six months and four years after the insertion of Marmor knee prostheses in 135 patients (ninety-three with rheumatoid arthritis and forty-two with osteoarthrosis) operated on at the Orthopaedic Clinic of the University of Uppsala between 1975 and 1979. The results were very good and the few complications that arose were easily resolved. The authors have therefore adopted the Marmor prosthesis for routine use. The only valid alternative to this type of prosthesis is the spherocentric prosthesis, which was applied after failures with the Marmor or other types of prosthesis, in cases involving varus or valgus deformity exceeding 30 degrees, and in cases of severe bone destruction.
