ABSTRACT
A tibial cut, referring to the center of the intercondylar eminence in knee replacement, often leads to malalignment due to unnoticed preexisting tibial deformities. This research preoperatively measured the proximal tibial reference point in full-length, weight-bearing lower limb radiographs, and the same reference point was replicated intraoperatively. Postoperative measurements were taken to evaluate the lower limb alignment. The result shows that optimal lower limb alignment and tibial component angle were achieved. The proximal tibial reference point was placed medial from the center of the intracondylar eminence through preoperative measurements, increasing the survival of knee replacements with tibial valgus deformities.
