Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary outcome measure was the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index that measures functional outcome (ref). The secondary outcome measure was the EQ-5D and visual analogue scale (VAS) scale. Patients were assessed preoperatively and at follow-up at 1 year postoperatively. The posterolateral approach was used in all operations. LLD was measured on the postoperative x-rays. patients were divided into three groups: shortening group where the operated leg was more than 5mm shorter compared with the contralateral side, the restoration control group where the operated leg was within 5mm shortening and 9mm lengthening compared with the contralateral side, and the lengthening group where the operated leg became more than 9mm longer compared with the contralateral side.
