Total hip arthroplasty (THA) is a cost-effective surgical procedure to treat patients with end-stage hip arthritis with high patient satisfaction. Different surgical approaches to the hip have been used to successfully perform THA. However, the role of these surgical approaches on physical activity and early functional recovery in THA patients remains controversial.

In this thesis, we prospectively evaluated physical activity levels in patients with end-stage hip OA whom are undergoing elective THA. The primary focus was to evaluate the impact of different surgical approaches on physical activity levels as a measure of functional recovery in the immediate postoperative period.

Due to the muscle sparing nature, the DA approach demonstrated faster functional recovery in the early postoperative period compared to the DL approach. Further examination regarding the economic implications of the improved early function from the perspective of the patient, caregiver, and care payer may be indicated.
