Abstract
A surgical method for reducing post-operative knee failure in a knee undergoing arthroplasty by determining the pre-operative lateral displacement of the trochlear groove with respect to the femoral condyles, inserting a prosthetic implant with the condylar members having a lateral displacement which is a function of the determined pre-operative lateral displacement of the sulcus. The invention further includes an device which includes condyle members that are joined by an arched region, said region have a lateral displacement of between 1 mm and 15 mm with respect to said condyle members. The subject device addresses the problems of implant failure due to compressive force on the patella.
