简要总结
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
详细描述
Limb length discrepancy (LLD)less than 2cm is usually not noticeable and does not require treatment. LLD over 2cm is usually noticed by the individual affected leading to self compensation by walking on the ball of the foot (toe down) or by tilting the pelvis and curving the spine.Untreated LLD can lead to lower back pain and long leg arthritis of the hip LLD and its effects on patient function have been discussed in depth in the literature with respect to hip arthroplasty but there are few studies that have examined the effect on function of limb length discrepancy following TKA.
Improved surgical techniques and rehabilitation protocols have resulted in excellent knee function and range of motion following TKA.
The investigators are aiming from the study to improve functional outcome in patients with knee osteoarthritis undergoing TKA.
