Sports activities have become a fundamental part of our daily life, this has led to an overuse of load joints, being the knee the most relevant. Overuse injuries of the knee result from microtrauma associated with physical activity and exercise that exceeds the strength of the cartilage tissue.~The purpose of this study is to evaluate the usefulness and safety of hyaluronic acid in athlete patients with knee overuse syndrome. Investigators hypothesis is that hyaluronic acid y safe and can improve symptoms of knee pain in sports patients. . Scores recorder data will be made at 15 days, then at 3 and 6 months after two knee injections of hyaluronic acid with sorbitol (Synolis VA).~Synolis VA is a viscoelastic, sterile, non-pyrogenic, isotonic, buffered solution of 2% hyaluronic acid. The hyaluronic acid used in synolis VA is obtained from bacterial fermentation and has a high molecular weight of 2 mdaltons, it has a neutral pH of 6.8 - 7.4 like synovial fluid. High concentration and high molecular weight of hyaluronic acid combined with sorbitol limits its degradation and confers the capacity of viscoelastic solution to restore joint lubrication and shock absorption properties.~This research protocol has been approve by the ethics and research Institutional committee in ISSEMyM Tlalnepantla Estado de Mexico number: CEI/0504/PI./2022. All participants must sign a informed consent to confirm be part fo this study.
Sports activity represents part of day living people, a knee pain originated by high demand joint activity could represent a limitation to continue sports. The aim of this clinical trial is demonstrate the effects of hyaluronic acid in sportsmen with knee pain.
