Background:
Role of MAKOplasty software in determining femoral neck version, distal-femoral resection angle, tibial axis difference, distal-femoral rotation, medial/lateral tibial slope, and tibial tubercle alignment has yet to be fully explored.
Methods:
Preoperative CT scans and plain films of 99 patients were obtained for each patient according to predetermined MAKO-protocol by four observers. Reliability analyses (Cronbach's Alpha-test) was performed to determine agreement between raters for angle measures.
Results:
Anatomic measurements were similar to previously published literature, and cronbachs'alpha analysis demonstrated agreement amidst all observers.
Conclusion:
MAKOplasty software produces similar results to anatomic measurements in planning for TKA with good reproducibility.
