J Arthroplasty 19 19-22. A technique is described of downsizing and lateralizing the tibial component and removing the proximal medial tibia flush with the implant.

Am J Knee Surg 12 222-228. A cadaveric study was performed that demonstrated the amount of varus correction with sequential releases of the posteromedial capsule oblique ligament complex, superficial medial collateral ligament, pes anserinus, and semimembranosus tendons.

In patients with a fixed varus contracture, use of a posterior cruciate–retaining implant results in increased pain, increased radiolucencies, decreased motion, increased revision rate, and decreased implant survivorship compared to patients with a posterior cruciate–substituting implant design.

Knees with severe preoperative angular deformities perform as well as deformity-free knees and should not be excluded from surgical treatment.
