What is the Midterm Survivorship and Function After Hip Resurfacing?

Abstract

Background Hip resurfacing arthroplasty is a common procedure that improves functional scores and has a reported survivorship between 95% and 98% at 5 years. However, most studies are reported from the pioneering rather than independent centers or have relatively small patient numbers or less than five years followup. Various factors have been implicated in early failure. Questions/purposes Our purposes were to determine: (1) the midterm survival of the BHR; (2) the function in patients treated with hip resurfacing; and (3) whether age, gender, BMI, or size of components related to failure. Methods We reviewed the first 302 patients (329 hips) on whom we performed resurfacing arthroplasty. We assessed the survivorship, change in functional hip scores (HHS, OHS, WOMAC, UCLA), and analyzed potential risk factors (age, gender, BMI, component size) for failure. The mean age at the time of surgery was 56.0 years (range, 28.2-75.5 years). The minimum followup was 5 years (mean, 6.6 years; range, 5-9.2 years).Results Kaplan-Meier analysis showed survival of 96.5% (95% CI, 94.7-98.4) at 9 years taking revision

Patients Report Improvement in Quality of Life and Satisfaction After Hip Resurfacing Arthroplasty

“…Our assessment of generic QoL (SF-12) demonstrated improvements on the physical and mental component scores comparable to the nonarthritic population. These outcomes support and underscore recent reports on WOMAC scores [25,38,39,41,57,59,69,70] and Oxford Hip Scores [31,36,[56][57][58] from other authors and patient populations. Our SF-12 results are in agreement with published SF-12 and SF-36 outcomes, which demonstrate restoration of generic QoL approaching that of the normal population [16,41,56,58] (Table 4).…”

Revision Rate and Patient-Reported Outcome After Hip Resurfacing Arthroplasty: A Concise Follow-Up of 1064 Cases

“…The mean postoperative UCLA score value of 5.8 found in the current study was slightly below those reported by others. For example, Patel et al found a mean UCLA score of 6.8 at a mean follow-up of 62 months in a cohort of HRA patients [32], while Rahman et al reported a mean score of 7.5 after a mean follow-up of 6.6 years [33]. Whether our somewhat lower score values are attributable to different baseline characteristics, differences in follow-up time or to cross-cultural differences cannot be determined.…”

Avoiding Short-term Femoral Neck Fracture With Imageless Computer Navigation for Hip Resurfacing

“…Midterm survivorship in hip resurfacing has been reported between 95% and 96% [17,29,37]. If the femoral component fails, it is often the result of femoral neck fracture or aseptic loosening.…”

“…Hip resurfacing is an alternative to THA for the young, active patient with reported midterm survivorship of 95% to 96% [17,29,37]. Advantages of hip resurfacing include preservation of metaphyseal and diaphyseal bone, improved joint stability, and favorable wear characteristics of a metal-on-metal articulation.…”
