  1. S1: The chief surgeon applied varus force to tension the lateral collateral ligament throughout the range of motion, followed by valgus force to tension the medial collateral ligament. The ligament tension assessment data were saved and labelled as S1
  2. S2: The chief surgeon repeated the process with varus and valgus force applied again. The ligament tension assessment data were saved and labelled as S2
  3. ICC: Intra-class correlation; CI: Confidence interval
