No adverse clinical outcomes found in patients with severe varus deformity after mini-midvastus TKA

March 5, 2015

In patients with severe varus deformity of the knee, mini-midvastus total knee arthroplasty had no adverse clinical outcomes as a result of poor implant position, according to study results.

Researchers compared 52 patients with a tibiofemoral mechanical axis of 195° or greater with a matched control group of 55 patients with a tibiofemoral mechanical axis of less than 195°. The researchers obtained clinical and radiographic evaluations according to the American Knee Society rating system preoperatively and postoperatively and compared postoperative patient satisfaction among the two groups. Patients were followed-up for a mean of 3 years.
