Figure 3: Changes in joint gap balance between intraoperative and postoperative measurements. (a) Intraoperative extension gap balance (iEGB) of 2.6° varus significantly differs from postoperative extension gap balance (pEGB) of 0.77° valgus in neutral position ( ). (b) No significant difference is observed between intraoperative flexion gap balance (iFGB) and postoperative flexion gap balance (pFGB) in neutral position.
