Long-term results of posterior-cruciate-retaining Genesis I total knee arthroplasty

Abstract Background Long-term results of Genesis I modular total knee system are not well known. Methods We analyzed data from 345 patients with 393 primary total knee arthroplasties (TKA) using the Genesis I prosthesis. In all cases, the posterior cruciate ligament (PCL) was retained, and the patella was not resurfaced. The minimum follow-up was 10 (range 10–16) years. Results Preoperative range of motion improved from 89° preoperatively to 105° at the time of the most recent follow-up ( p p p Conclusions In the long term (up to 16 years), PCL-retaining Genesis I total knee prosthesis is associated with good functional outcomes and low failure rates.
