Howard Chansky, MD, Professor
Justin Klimisch, MD
Nicholas Wegner, MD, Orthopaedic Surgery Resident
Total knee replacement surgery (TKA) has revolutionized care of osteoarthritis over the past 40 years. Given its success, there has been a rapid increase in the number of TKAs performed yearly, which is projected to continue to increase in the coming years. In this Grand Rounds, UW Medicine physicians Howard Chansky, Justin Klimisch, and Nicholas Wegner review the history of total knee arthroplasty, focusing on the historical development beginning in the 1860s and then focus on the explosion of new designs developed during the 1970s. Modern approaches used in primary and revision total knee arthroplasty are then reviewed. Case studies are highlighted that demonstrate some of the challenges of primary and revision TKA.
