Factors Influencing Range of Motion After Contemporary Total Knee Arthroplasty

A detailed analysis of 219 total knee arthroplasties performed with a single implant design was performed. Factors significantly affecting the postoperative range of motion of total knee arthroplasties 2 years after surgery included preoperative diagnosis and preoperative range of motion. Sex, age, body mass index, femoral component size, posterior cruciate ligament status, or fixed vs mobile bearing design did not correlate with knee range of motion 2 years postoperatively.
