Is There an Association Between Preoperative Emotional Health and Postoperative Exercise Adherence After Total Knee Arthroplasty?

Total knee arthroplasty (TKA) is an extremely successful operation, yet some patients do not achieve the expected increase in function postoperatively despite a skilled operative procedure using a prosthetic design with a proven track record. Total knee arthroplasty patients who have a low MCS are less likely to improve physically after TKA. We have shown that low-MCS patients report more anxiety and depression than high-MCS patients. Limited evidence exists regarding rehabilitation after TKA and how MCS may effect postoperative rehabilitation and exercise adherence after TKA.
