Purpose: Conflicting evidence exists about the appropriate intra-operative soft tissue balance in posterior-stabilized (PS) total knee arthroplasty (TKA). The purpose of this prospective observational study was to investigate the impact of intra-operative soft tissue balance on post-operative knee flexion angle. Methods: A single surgeon performed 164 TKAs using a single brand of PS prosthesis via the subvastus approach without using a pneumatic tourniquet. Intra-operative soft tissue balance was quantified as the gaps between the femoral component and tibial osteotomy surface with the knee flexed at 0°, 30°, 90°, and 120° with the patellofemoral joint reduced. Multiple regression analyses were employed to identify independent predictors of knee flexion angle 1 year after TKA. Result: The pre-operative knee flexion angle and the gap difference between 120° and 0° flexion were positively correlated with knee flexion angle 1 year after TKA [β = 0.37, 95% confidence interval (CI) 0.26–0.48, P |
