Abstract
Introduction
Total joint arthroplasty is regarded as a highly successful procedure. However, patient outcomes and implant longevity require proper alignment and prosthesis position. Computer-assisted total knee arthroplasty (TKA) has been found to improve the accuracy of component positioning and reduce rates of revision, however there remains debate whether it provides improvements in patient reported outcomes (PROs). The purpose of our study was to compare PROs between computer-assisted and conventional TKA.
Methods
A retrospective review of all total knee arthroplasty patients was conducted using a single institution's FORCE database for reporting PROs. Knee Society Score (KSS), procedure satisfaction, physical component summary (PCS), and mental component summary (MCS) were compared between computer-assisted TKA and conventional TKA.
Results
Computer-assisted TKA had a higher average KSS (68.8 vs 44.6), PCS (33.8 vs 30.4), and MCS (51.1 vs 47.5) compared to conventional TKA. The average procedural satisfaction (4.0 vs 4.2) was equivalent between computer-assisted and conventional TKA, respectively.
Discussion
Computer-assisted TKA improves patient reported outcomes while providing equivalent satisfaction compared to conventional TKA.
