Brief Summary

To What degree total knee replacement (TKA) affects leg length discrepancy in patients with varus deformity? Varus deformity, the most commonly encountered deformity in patients undergoing TKA is associated with limb alignment and varying degrees of contractures of medial soft tissue structures, laxity of the lateral soft tissue structures, flexion deformity and medial bone erosion at the knee joint .The challenges in performing TKA in a varus arthritic knee include restoration of limb alignment, balancing the medial and lateral soft tissue tension, equalizing flexion and extension gaps and restoring medial bone loss
