Abstract
Purposes
The objectives of this study were to investigate patient-reported outcomes and referral pain at the first visit in patients with osteonecrosis of the femoral head (ONFH) and to clarify the influence of collapse of the femoral head and the contralateral condition.
Methods
The study included 105 patients (130 hips) with ONFH at the first visit, who were divided into two groups based on the presence of bilateral walking hip pain (bilateral group 25 patients, 50 hips) and unilateral hip pain (unilateral group 80 patients, 80 hips). We compared the Short Form-36 (SF-36), Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire (JHEQ), and visual analog scale (VAS) responses for hip, knee, and low back pain between the groups to investigate the influence of the contralateral condition. Regarding the influence of femoral head collapse, we investigated these subjects based on the stage classification in the unilateral group.
Results
The physical component summary (PCS) of the SF-36 and all domains of the JHEQ were poorer in the bilateral group than in the unilateral group. In addition, the VAS score for low back pain was significantly poorer in the bilateral group than in the unilateral group. Regarding the collapse of the femoral head, the SF-36 for the PCS and JHEQ for pain had a significant relationship in the ONFH stage. The VAS scores for hip and knee pain had a significant relationship in the ONFH stage.
Conclusion
Collapse of the femoral head and the contralateral condition of ONFH strongly affect patients’ activities of daily life.
