title: Total Knee Arthroplasty in Patients With Cerebral Palsy: A Matched Cohort Study to Patients With Osteoarthritis.
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  TKA is a safe, durable procedure in patients with CP to improve pain and function.
