Limb length inequality
After total hip arthroplasty, a few patients may feel a discrepancy between the two legs. The leg may falsely seem longer after the surgery. the chronic arthritis in some patients prior to the surgery may lead to hip joint contractures following the surgery. this may appear as discrepancy in leg length. Post-surgical rehabilitation and restoring the joint mobility would lessen the situation gradually. Factors associated with limb-length discrepancy include:
- Weakness of abductor muscles
- Pelvic inequality
- Hip joint lengthening during operation
