Risk of Chronic Post-surgical Pain After TKA

Risk of Chronic Post-surgical Pain After Simultaneous Versus Staged Bilateral Knee Arthroplasty: A Retrospective Study With Propensity Score Matching

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.

Inclusion Criteria:

• From October 12, 2012 to December 2, 2021, patients who underwent bilateral or staged knee replacement surgery during a single hospitalization under Professor Lee Woo-seok at the Department of Orthopedics at Gangnam Severance Hospital due to bilateral knee arthritis.

Exclusion Criteria:

• Patients whose post-operative pain information cannot be confirmed through outpatient visit records 1 year after surgery
• Those who have undergone surgery other than knee arthritis surgery within 1 year after surgery
