Metal-on-Metal Hip Resurfacing Arthroplasty: A Survivorship and Clinical Outcomes Analysis of Over 1300 Cases


Edwin P. Su, MD

Project Description

Metal-on-metal hip resurfacing arthroplasty has become a viable alternative to total hip arthroplasty in the younger, active adult with degenerative hip disease, and encouraging mid-term results have been reported. Proposed advantages of hip resurfacing arthroplasty versus total hip arthroplasty include preservation of bone stock, improved stress transfer, decreased dislocation, and the ease of future revision surgeries.  However, hip resurfacing arthroplasty is a relatively new procedure, as it only received FDA approval in the United States in 2006; thus, questions remain regarding the long-term functional outcomes associated with metal-on-metal hip resurfacings. Dr. Su has been at the forefront of the development and performance of hip resurfacing arthroplasties since their early clinical trials, and to date, has performed over 1300 hip resurfacing procedures. He has continuously collected clinical outcome scores and vital patient information that will prove useful in determining the long-term effectiveness of hip resurfacing arthroplasty.The role of the medical student will be to assist with clinical and functional outcomes collection, and data analysis, with the ultimate goal being to produce a manuscript for publication assessing the survivorship of hip resurfacing arthroplasty. This would be the largest cohort of patients having undergone a hip resurfacing arthroplasty reported by a single surgeon.  Through this process, the medical student will also gain valuable experiences both in the operating room, and through patient interactions in Dr. Su’s clinic, while examining patients for functional outcomes collection.
