Summary.

During 1977 to 1986, 106 patients had isolated patellar prostheses, with both patellar and femoral components, inserted in 20 different hospitals in Sweden. At follow up, 7 years (range 3 to 14 years) after operation, 9 patients had died so that 97 patients with operations on 113 knees were included in this study. Thirty-three (38 knees) had been operated on before or after a prosthesis had been inserted. At follow-up, 75% were satisfied with the operation; 83% had improved, 59% could walk without an aid and 44% had no, or only occasional, pain in the knee. These results encourage the use of an isolated patellar prosthesis in cases of advanced and disabling localised patellar arthrosis. There is no place for this operation in the treatment of chondromalacia.
