Abstract
In an evaluation of 245 variable axis total knee arthroplasties, no significant deterioration of results were found five to nine years after implantation. The patellar problems originally reported diminished with the use of a patellar button, widening of the flange on the femoral component and the increased use of lateral retinacular release. The local complications were: severe patellar problems, 6.9%; ligamentous laxity, 2.9%; aseptic loosening, 1.2%; deep infections, 2.0%; supracondylar fractures, 1.2%; peroneal nerve palsy, 1.6%.
