BACKGROUND: Hip osteoarthritis is a common degenerative disease that frequently affects active adults, most of the times requiring from conservative treatment until total hip arthroplasty when these fail. Nowadays still THA is the standard treatment although the long-term revision rate in young patients is high. Hip resurfacing arthroplasty, certainly ceramic-on-ceramic is a new potential alternative preserving bone stock and with the possibility of providing better functional outcomes. The evidence comparing CoC HRA and THA is still very limited. Accordingly, this study’s purpose is to compare both procedures in terms of functional recovery, pain and complication rates. OBJECTIVE: The main objective is to evaluate if resurfacing prosthesis have a faster and a better functional recuperation in comparison to conventional total hip arthroplasty. DESIGN AND SETTING: The study is a randomized, single-blind, controlled clinical trial, unicentric, that will be carried out in Donostiako Unibertsitate Ospitalea, within the Orthopaedics and Trauma Surgery Department for 5 years. Patients undergoing surgery and a posterior physiotherapy program and attend to the consultations to control their clinical and functional evolution evaluated by the Harris Hip Score scale. PARTICIPANTS: Patients between 40 and 65 years old diagnosed with osteoarthritis that after failing all conservative treatments are eligible for a total hip arthroplasty. A total of n=76 cases are needed, based on a precision-based sample size calculation for diagnostic accuracy. METHODS: A non-probabilistic, consecutive method of recruitment will be used. 76 patients within 40-65 years diagnosed with osteoarthritis will be randomly assigned, in a 1:1 ratio, to total hip arthroplasty or resurfacing hip arthroplasty. Patients will follow a physiotherapy program for 3 months to do a proper rehabilitation, and they will be followed after the surgery in consultations evaluating functional capacity and pain of the patients the 2nd, 4th and 8th week with the HHS and AVS scales. Patients will also have to do a blood test every year in order to control the blood ions. We will also follow-up and report any complication that may be developed. There will be done comparative and multivariate analyses, that will help to identify differences between groups, considering covariates as age, BMI and surgeon experience
