Introduction: total knee arthroplasty (TKA) is a surgical procedure widely used to treat pain, improve function and correct deformities in patients with various knee conditions Preoperative training or also known as “prehabilitation” emerges as a new approach to rehabilitation and refers to a set of interventions designed to optimize patient health prior to surgery through exercise programs and patient education. This article aims to determine the effects of preoperative training in patients undergoing RTA. Methods: a systematic review was carried out using the scientific databases: PubMed, Cochrane and Scopus, following the guidelines of the PRISMA model. We selected articles published within the last 5 years in English and Spanish with a population older than or equal to 50 years of age. Results: eleven RCTs were analyzed, these trials addressed different types of preoperative training within the intervention protocol in this way one trial of strength, another of balance, six of resistance, and three of strength combined with balance, in such a way it is determined to perform 4 weeks of training. Conclusions: it was determined that preoperative training in patients undergoing RTA improves muscle strength of the knee extensor muscles (quadriceps), functionality and physical activity status
