BACKGROUND Osteonecrosis of the femoral head (ONFH) is a prevalent clinical condition, and as the affected population becomes younger and more widespread, an increasing number of patients prefer to retain their own hip joints. In comparison to joint replacement and hip-preserving surgeries, conservative hip preservation treatment is gaining more recognition from both clinicians and patients. AIM To observe the clinical efficacy and influencing factors of conservative hip preservation treatment for patients with ONFH. METHODS A total of 73 patients (119 hips) were included, and patients were grouped based on Association Research Circulation Osseous (ARCO) stage, Japanese Investigation Committee (JIC) classification, lesion size, and collapse degree. The clinical efficacy of conservative hip preservation treatment was evaluated from two aspects: Radiological progression and clinical functional scores [Harris Hip Score, Western Ontario and McMaster Universities Arthritis Index (WOMAC), international Hip Outcome Tool 12 (iHOT-12), and visual analogue scale (VAS)]. Analyzing the success rate of conservative hip preservation based on conversion to total hip arthroplasty or hip preservation surgery. RESULTS In this retrospective cohort study, we retrospectively analyzed 73 patients (119 hips) with an average follow-up time of 53.58 ± 26.80 (18-129) months. The overall success rate of hip preservation is 90.76%. The success rates of hip preservation in ARCO I-II, IIIa, and IIIb were ...
