Raising the Joint Line in TKA is Associated With Mid-flexion Laxity: A Study in Cadaver Knees.

CONCLUSIONS: Despite a well-balanced knee in full extension and at 90° flexion, increased mid-flexion laxity in the coronal plane was evident in the specimens where the joint line was raised.
CLINICAL RELEVANCE: When recutting the distal and posterior femur and downsizing the femoral component, surgeons should be aware that this action might increase the laxity in mid-flexion, even if the knee is stable at 0° and 90°.
