ABSTRACT
PURPOSE:
The aim of this study was to compare the clinical outcomes of cementless total hip arthroplasty (THA) used for the treatment of osteonecrosis of the femoral head (ONFH) and for osteoarthritis (OA) at a mean ten years follow-up.METHODS:
Case-control study of 78 patients (86 hips) who underwent THA for ONFH treatment (ONFH group). Patients were matched for age and sex to 78 patients (86 hips) who underwent THA for OA (OA group). We compared the clinical and patient-reported outcomes, implant survival rates, and rates of complications between the groups.RESULTS:
There were no between-group differences in the Harris Hip Score and in the following patient-reported outcomes at the last follow-up Japanese Orthopedic Association Hip-Disease Evaluation Questionnaire (JHEQ) pain and movement scores and the Physical Component Summary and Role/Social Component Summary scores of Short Form-36 (SF-36). However, the mental score of the JHEQ, the Mental Component Summary score of SF-36, and The Visual Analog Scale score for satisfaction were lower for the ONFH group than for OA group. The rate of complication was equivalent between the groups 5% for the ONFH group and 3% for the OA group. The ten year implant survival rate was equivalent between the groups, at 97.5% for the ONFH group and 98.2% for the OA group.CONCLUSION:
The functional outcomes, implant survival, and rate of complications for cementless THAs are comparable at a mean follow-up of ten years for ONFH and OA.Palabras clave
