Conditions

Bilateral Total Knee Chronic Pain Following Arthroplasty

Brief summary

Chronic post-surgical pain (CPSP) is a common surgical complication. The role of timing in the development of CPSP after bilateral total knee arthroplasty (BTKA) is not well studied. We aimed to compare the occurrence of CPSP in patients who underwent simultaneous or staged BTKA without discharge between procedures.
