A Prospective Randomized Study of Bicompartmental vs. Total Knee Arthroplasty with Functional Testing and Short Term Outcome

50 patients with knee osteoarthritis in the medial and patellofemoral compartments were randomly allocated to undergo bicompartmental (BKA) or total knee arthroplasty (TKA). The purpose of this study was to compare functional and clinical outcomes between groups up to two years after surgery. At final follow-up, bicompartmental and total knee arthroplasty achieved similar improvements in function, Knee Scores, Oxford Scores, and satisfaction. More BKA patients could complete the step up and over activity and had less trouble climbing stairs compared to TKA patients at 1 month post-surgery. However, the authors did not expand this study by performing additional cases after bicompartmental patients underwent revisions and the Deuce tibial component was recalled.
