Fig. 1. Relationship between femoral and patellar components in ligament balance using the gap technique. (A) In case of lateral laxity, more external femoral rotation for ligament balance with the gap technique may show appropriate patellar tracking with the femoral component. (B) In case of medial laxity, internal femoral rotation may show good ligament balance and patellar tracking. TEA: transepicondylar axis.
