Outcomes of the conservative hip preservation treatment in patients with osteonecrosis of the femoral head: With 4-year follow-up.
Article in World journal of orthopedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOsteonecrosis 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.
aimTo observe the clinical efficacy and influencing factors of conservative hip preservation treatment for patients with ONFH.
methodsA 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.
resultsIn 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 97.67%, 91.53%, and 70.59%, respectively (
conclusionConservative hip preservation treatment can effectively treat ONFH, prevent the progression of the necrosis, and significantly improve the clinical function of patients. The radiological staging and lesion size at the initial visit may help determine the prognosis of conservative hip preservation treatment.
