摘要: Abstract With increased precision in alignment offered by new generations of instrumentation and customized guides, this study was designed to establish a biomechanically-based target for the balance tibial loading order diminish likelihood pain subsidence related mechanical overload post-UKA. Sixty composite tibias were implanted with Oxford UKA components varied sagittal slope, resection depth, rotation medial shift using patient matched instrumentation. Digital image correlation strain gage analysis conducted static evaluate distribution as result component alignment. In model, minimal distal most lateral positioning, neutral rotation, 3°of slope (from axis) exhibited balanced response following UKA.
