“…First, we have no information regarding histologic analyses of the revised components, which could partially explain some of the failure patterns. Second, some outcome scores were determined only at the final followup, because these measures previously were unavailable in German [27,30]. Third, three patients (four hips) were lost before the final followup.…”

Background/rationale There is growing evidence that different resurfacing implants are associated with variable survival and revision rates. A registry analysis indicated the Durom resurfacing implant had high revision rates at 5 years, whereas three original studies reported low revision rates at short-term followups. Thus, the revision rates appear controversial. Questions/purposes We therefore assessed (1) the survivorship including differences between women and men at a mean of 5 years after resurfacing with the Durom implant, and (2) clinical scores and radiographic parameters. Patients and Methods We prospectively followed all 100 Durom hip resurfacings implanted in 91 patients (25 women and 66 men; mean age, 52 years) between 2003 and 2004. Survivorship analysis was performed with pending revision or revision for any reason as the endpoint. The minimum followup was 47 months (mean, 60 months; range, 47-72 months).Results At a mean of 5 years, 11 hips were revised for various reasons. Cumulative survival was 88.2% for all patients and 81.5% for women. The mean Oxford (OHS) and Harris hip (HHS) scores were 14.6 and 94.7, respectively. The mean UCLA activity level was 7.9. Sclerotic changes around the short femoral stem (pedestal sign) were detected in 40% of the hips. We observed considerable femoral neck thinning with component-to-neck ratios of 0.85 preoperatively and 0.82 at 5 years. Conclusions Our study highlights a high revision rate 5 years after hip resurfacing with the Durom implant. This observation underlines previous findings from registry data and suggests that revision rates increase with time.

“…At baseline, patients completed crossculturally adapted and validated German versions of the following questionnaires: (1) Oxford Hip Score (OHS) [7,29], which consists of 12 questions on hip pain and function in the past 4 weeks. Each item uses a 5-point response scale with values from 0 to 4.…”

Background Many studies report differences in patientreported outcome measures (PROMs) for men and women undergoing total hip arthroplasty (THA). Few studies have evaluated whether these are explained by corresponding differences in important preoperative factors. Questions/purposes (1) Are there differences between men and women in PROM scores preoperatively and 12 months after THA? (2) Do baseline differences in comorbidity, age, body mass index (BMI), and mental health status explain these differences in PROM scores? Methods Preoperatively, 300 patients completed the Oxford Hip Score (OHS), WOMAC, and SF-12; 261 (86%) of them (129 women, 64 ± 11 years; 132 men, 66 ± 10 years) completed the same questionnaires 12 months postoperatively and also rated the acceptability of their current symptoms and change in general health. Results Preoperatively, women showed worse scores than men in the OHS (À1.9; 95% confidence interval, À3.6 to À0.3) and WOMAC (À6.3; À10.9 to À1.7). At 12 months postoperatively, the absolute scores for all PROMs were not significantly different. After controlling for BMI, age, comorbidity, SF-12 mental health scores, and sociodemographic characteristics, the baseline differences remained. Conclusions Surgeons may be more reluctant to operate on women than men because they perceive that, because of their worse baseline status, women are likely to have worse outcomes; however, given that we found no evidence for differences in patient-reported outcomes at 12 months, these suspicions would appear to be unfounded. Women and men can be expected to benefit to a similar extent from THA. Level of Evidence Level III, therapeutic study.

“…Clinical and radiographic followups were scheduled at 6 weeks, 6 months, and 12 to 24 months after surgery. In November 2011, we obtained current Oxford Hip Scores and UCLA Activity Scores from the four patients who could be located [43,44]. A followup MRI was performed 6 months postoperatively to assess lesion healing and resolution of bone marrow edema.…”
