Abstract: Background:Resurfacing Arthroplasty (RA) of the hip has undergone resurgence with initially mainly good clinical results in young patients. It was mainly performed in younger more active patients with severe symptomatic arthritis of the hip including pelvic deformity. Furthermore the proximal femoral anatomy was preserved for surgical procedures in the future. Objective:The aim of the study was to perform a prospective review of the very first 85 hips that had implantation of one cementless resurfacing system and a mean follow up of 5 years. Methods:85 cementless Total Hip Resurfacing devices have been performed in 75 patients in our orthopaedic department. The mean age of the study group was 49.8 years. Harries Hip Score, clinical examination data and radiographic parameters including the neck shaft angle (NSA), stem shaft angle (SSA) and detection of radiolucencies were analyzed. Results:Estimated implant survival at five years of follow-up was 88.2% at 5 years follow-up using revision for all causes as the end point. Mean HHS was 92.5 (range 80–100) five years after Resurfacing Arthroplasty. Conclusions:In conclusion we have to admit, that there was a high proportion of failed hip resurfacings but in the proportion that succeeded we saw good clinical results.
