title: Outcome following total knee arthroplasty in obese versus non-obese Asian patients.
abstract: OBJECTIVE
  To compare the outcome following total knee arthroplasty (TKA) in obese and non-obese Asian patients.
  
  
  METHODS
  27 obese patients were compared with 27 non-obese controls matched for age, gender, diagnosis (osteoarthritis), prosthesis, preoperative Knee Society knee and function scores, preoperative Oxford Knee Score, and follow-up duration. All TKAs were performed by a single surgeon. Patients were assessed at 6 months and 2 years for the range of motion, Knee Society knee and function scores, Oxford Knee Score, and Short Form-36 Health Survey (SF-36).
  
  
  RESULTS
  The obese and non-obese groups did not differ significantly in pre- and post-operative variables: range of motion, Knee Society knee and function scores, Oxford Knee Score, and SF-36 score. Using revision as an end-point, implant survival was 100%. There were no intra- or post-operative complications in either group.
  
  
  CONCLUSIONS
  Obese and non-obese Asian patients achieved a comparable outcome following TKA.
