Abstract

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.
