title: Patient related functional outcome after total wrist arthroplasty: a single center study of 206 cases.
abstract: OBJECTIVE
  To prospectively evaluate patient related outcome measures after total wrist arthroplasty (TWA) using four different total wrist implants operated at a single referral center in Sweden.
  
  
  METHODS
  206 primary TWAs were assessed preoperatively and after one year postoperatively with respect to the following eight outcome measures: Range of motion (flexion/extension, radial/ulnar deviation, pronation/supination), hand grip strength, Canadian Occupational Performance Measure (COPM), performance and satisfaction, Visual Analog Scale (VAS) pain scores at rest and in activity.
  
  
  RESULTS
  The Maestro TWA had a significantly greater improvement of radial/ulnar deviation than the Biax and Remotion TWAs. COPM performance and satisfaction improved more for the Maestro and Universal 2 prostheses than the Biax and Remotion.
  
  
  CONCLUSIONS
  All four TWAs offer reduced VAS-scores and improved COPM-scores with preserved hand grip strength and somewhat improved range of motion. The Maestro TWA performed favorably compared to the Remotion TWA. Implant design may affect patient related outcome.
