Currently, few data examine the use of total knee arthroplasty (TKA) in patients with cerebral palsy (CP). This study reviewed the outcomes of TKA in patients with CP compared with a matched cohort undergoing TKA for primary osteoarthritis.


Over a 28-year period, 15 TKAs in patients with a diagnosis of CP were identified. The cohort was 53% men, with a mean age of 58 years. Patients with CP were matched 1:2 based on age, sex, body mass index, and year of surgery with a group of patients undergoing TKA for osteoarthritis.


No difference was reported in implant survival (P = 0.27) or revision surgery (P = 0.79) between groups. All patients were ambulatory postoperatively, and significant increases were noted in the Knee Society score (P < 0.0001) and functional assessment (P = 0.003).


TKA is a safe, durable procedure in patients with CP to improve pain and function.
