Abstract
A lateral approach without ligament release was performed in 475 primary to tal knee arthroplasties (TKAs) in 344 patients and 50 revision TKAs in 39 p atients. Deformities of the genu varum or valgum were corrected by accurate bone cut; no ligament releases were required other than to achieve adequat e exposure. A lateral approach allowed both self-centering of the extensor mechanism and knee closure in complete flexion. Better range of motion was achieved. More than 90 degree active flexion usually occurred 3 days postop eratively. Postoperative roentgenograms showed all knees had good varus and valgus stability, which was sustained with time, except 1 with late genu r ecurvatum due to inadequate polyethylene thickness and the other with a bro ken tibial base plate. Complications such as disruption of patellar blood s upply and knee instability, more frequently observed in the medial approach with ligament release, did not occur. The results suggest that this new te chnique is safe and may give better outcomes.
