Total knee arthroplasty is a surgical procedure that is commonly used for pain relief and movement restoration in cases of severe arthritis. The knee implant design plays a vital role in determining patients' activity levels after total knee replacement. Of the 90 percent of younger patients who undergo knee replacement surgeries, restriction is caused by the implant design. This article discusses the parameters that affect activity levels after total knee replacement, and describes the aspects of a novel knee design that allow normal high flexion activity even after total knee replacement.
