Abstract

Objectives: 1. To describe the characteristics of leg length discrepancy in patients after bilateral total hip arthroplasty. 2. To evaluate the patient's hip function after bilateral total hip arthroplasty at Hanoi Medical University Hospital. Materials and methods: A descriptive cross-sectional study involving 64 patients, including 71 men and 12 women, with an average age of 51.7 ± 13.3 years, of which 71 patients have avascular osteonecrosis of the femoral head and 12 patients with bilateral hip osteoarthritis underwent total hip arthroplasty one by one at Hanoi Medical University Hospital from January 2021 to January 2024. The surgical outcomes were evaluated for at least six months after surgery. Leg length discrepancy was assessed clinically and radiographically. The Oxford Hip Score (OHS) was used to evaluate patients' hip function. Results: 34/49 (40.9) patients felt a difference in lower limb length after surgery. The difference in lower limb length measured clinically is 9.15 ± 6.47 mm (0-20), X-ray is 6.05 ± 3.77mm (0-19). The average OHS after surgery was 45.98 ±2.69 (38- 48). There is no relation between leg length discrepancy and OHS. Conclusion: Patients following bilateral total hip replacement surgery have a slight leg length discrepancy and good hip function.
