Key: numbers listed in each cell are ones which were statistically significant. Listed in the order of Odds Ratio; (95% Confidence Intervals); p-value. MTP = medial tibial plateau; LTP = lateral tibial plateau; MFC = medial femoral condyle; ADL = activities of daily living; Sports/Rec = sports and recreation; QOL = quality of life.
