Total hip arthroplasty in advanced osteonecrosis: The short-term results by metal-on-metal hip resurfacing

Abstract

SummaryBackgroundCharacteristically, osteonecrosis affects younger patients who typically refer to the orthopedic surgeon for the first time in the third to fifth decades of life, in the late stages of the disease. Femoral metal-on-metal hip resurfacing is as an alternative to conventional total hip arthroplasty in treating osteoarthritis of the hip. Since there are already many reports regarding the successful outcome of resurfacing in advanced osteoarthritis, the purpose of this study was to analyze the clinical outcomes of this procedure in patients with osteonecrosis of the femoral head and to compare them with a matched group of patients with osteoarthritis.Material/MethodsThis retrospective cohort study evaluated a consecutive series of 52 patients with end-stage osteonecrosis (28 patients) and osteoarthritis (24 patients) of the femoral head, managed by metal-on-metal hip resurfacing in a referral orthopedic center from Feb 2002 to May 2007. Pain, function and deformity were evaluated with the use of the Harris hip score after the operation. Patients were clinically followed for a mean of 41 months.ResultsThe patients in the osteoarthritis group had a significantly higher mean age than those in the osteonecrosis group (47.88±12.6 vs 30.86±7.5, p=0.003).The clinical outcomes were similar for both groups. There was no significant difference in mean Harris hip score (p=0.347) and hip joint range of motion (p=0.346) between osteonecrosis and osteoarthritis groups after surgery.ConclusionsOn the basis of these initial findings, we recommend MOM resurfacing as a viable treatment option for patients with advanced stages of osteonecrosis.

Early Unpleasant Postoperative Symptoms for Patients Undergoing Primary Hip versus Primary Knee Replacement: Patient Perception

“…In the present study, patients who underwent THR and TKR was encountered more among female, this agree with Liu et al (2012) and Stark (2016) [32,33] . In the opposite direction, Madadi et al (2011) and Thomas, Barrett, Tupper, Dacenko-Grawe, and Holm (2014) found that most of their studied patients were male [34,35] . As regards educational level, the findings of the present study represented that, more than half of patients, were non-educated.…”

IL-15 deficiency alleviates steroid-induced osteonecrosis of the femoral head by impact osteoclasts via RANKL-RANK-OPG system

“…Steroid-induced ONFH can lead to the femoral head collapse and subsequent hip joint destroys, which will significantly affect the patients' activities [15][16][17]. For steroids could target on multi-system or organs, it is relatively difficult to systemically interpret the mechanism involved in steroid-induced ONFH.…”

Effect of surgical treatment on the quality of life in patients with non-traumatic avascular necrosis of the femoral head

“…Our results were consistent with those obtained by Madadi, who reported that the mean postoperative HHS was 94. 9 Moreover, Mont et al 10 reported a mean preoperative score of 52. These values suggest the substantial disability, pain and reduced joint range of motion among patients.…”
