- Primary Outcome Measures
Name Time Method Depth ratio(Tibial) Post operative ratio between the depth of vertical tibial bone cut and the shortest distance between the lowest point of the vertical tibial bone cut to the medial tibial cortex
- Secondary Outcome Measures
Name Time Method Depth ratio(Keel) Post operativ Depth ratio(Keel) is the ratio of distance between joint line and lowest part of keel bone cut and the shortest distance between the lowest point of the keel bone cut to the medial tibial cortex,Lateralized ratio post operative ratio between distance from medial cortex of tibial plateau to tip of tibial component keel and distance from tip of tibial component keel to lateral cortex of tibial plateau, perpendicular toaxis.,Tip to cortex distance (AP) Post operative is the shortest distance between the tip of tibial component keel and the outer margin of the medial tibial cortex,Tip to cortex distance (Lateral) post operative the shortest distance between the tip of tibial component keel and the outer margin of the posterior tibial cortex in lateral view
