Complex Regional Pain Syndrome Following Total Knee Arthroplasty

Abstract


Complex regional pain syndrome (CRPS) is an uncommon cause of residual pain after total knee arthroplasty (TKA). The presentation is variable, and there is no gold standard diagnostic test. Diagnosis is more difficult after TKA because some classic signs of CRPS may be unreliable and imaging may be difficult to interpret. Early intervention is the most important factor in predicting improvement, necessitating high suspicion in patients with exaggerated pain and stiffness after excluding more common causes. This article reviews the literature regarding CRPS following TKA, explains the diagnosis, and discusses treatment. [Orthopedics. 2020;43(6):e486–e491.]
