title: GUEPAR total knee prosthesis. Results and outcome of seven years' use in a district general hospital.
abstract: Between 1980 and 1987, 44 total knee arthroplasties of the GUEPAR type were performed in 38 patients with severe degenerative joint disease. The patients have been followed up for 7 years and 70% of cases had a good or fair result. The 13 poor results included five cases of deep sepsis, three of whom subsequently underwent successful arthrodesis at this hospital. Other causes of a poor outcome were loosening and patellofemoral dysfunction. Radiological review of 27 knees showed that 80% had lucent lines at either cement/prosthesis or bone/cement interface, although these radiological findings were not associated with clinical evidence of loosening. The major long-term complication was shown to be retropatellar pain, which was recognized in 16% of all cases. However, this would seem to be the only significant long-term complication, and we believe that with the use of a patellar button the GUEPAR prosthesis should continue to be used in selected cases of severe degenerative joint disease.
