Survival Study of the Genutech® Total Knee Arthroplasty

A prospective cohort study will be performed collecting patient's data before and after the total knee arthroplasty surgical procedure at one, five and ten years. The main goal of this work is to prospectively study the results obtained with the implantation of the knee prosthesis currently used in the Orthopaedic Service of Sant Rafael Hospital of Barcelona (Genutech®). The main outcome of the study is the survival of the implant, that is, having no revision surgeries in the follow-up. The secondary objective is the clinical and radiological evaluation of the implants measured by outcome measueres: Oxford Knee Score (OKS), SF12 questionnaire and WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) questionaire. OKS and SF12 scores are higher with good results and lower with bad results. WOMAC expresses results the other way around.
