INFLUENCE OF SURGICAL TECHNIQUE ON POST-OPERATIVE KNEE STABILITY IN POSTERIOR-STABILISED TOTAL KNEE ARTHROPLASTY

IntroductionTo achieve well aligned and balanced knee is essential for the post-operative outcome in total knee arthroplasty (TKA). Gap balancing technique can adjust the bone cut depending on the soft tissue balance in addition to soft tissue releases. Therefore, gap balancing technique would be more advantageous in soft tissue balance comparing to measured resection technique (MRT) in which soft tissue balancing relayed on soft tissue releases alone. Nevertheless, the influence of surgical technique on the post-operative knee stability has not been fully investigated.ObjectiveWe introduced a new surgical technique (medial gap technique: MGT) according to modified gap technique regarding medial knee stability as important. The intra-operative soft tissue balance and post-operative knee stability were compared between MGT and MRT in posterior-stabilized (PS) TKA for varus type osteoarthritic knees.Materials & MethodsSixty varus type osteoarthritis knees were involved in this study. PS type TKAs (NexGen LP...
