In a recent Orthopaedic Crossfire debate for Orthopedics This Week, HSS hip and knee surgeon Chitranjan S. Ranawat, MD, argued that the PFC Sigma Rotating Platform Posterior Stabilized (RPPS) design is successful for total knee replacements in young, active patients.

So, we're reporting 10-year results in young, active patients with a high quality of function including sporting activities. We attribute this to design features of the RPPS knee," said Dr. Ranawat during the debate at the Annual Current Concepts in Joint Replacement (CCJR) Winter meeting in Orlando, Florida.
