Hyaluronic Acid in Overuse Knee Pain

Phase 2

Completed

• Conditions: Overuse Injury; Overuse Injury; Body Mass Index in Athletes
• Interventions: Drug: KNEE JOINT INFILTRATION WITH HYALURONIC ACID WITH SORBITOL SYNOLIS VA

• Registration Number: NCT05450458
• Lead Sponsor: Hospital Regional Tlalnepantla

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Hyaluronic Acid group	KNEE JOINT INFILTRATION WITH HYALURONIC ACID WITH SORBITOL SYNOLIS VA	All overuse knee syndrome participants after both knee joint infiltration with two doses each of Synolis VA (2ml = 40 milligrams of hyaluronic acid with 80 milligrams of sorbitol).

Primary Outcome Measures

Name	Time	Method
Efficacy of Hyaluronic Acid With Sorbitol (SYNOLIS VA) in Overuse Knee Syndrome Assessed With the Knee Injury and Osteoarthritis Outcome Score (KOOS)	Baseline, 15 days, 3 months, and 6 months	To demonstrate that two doses of intra-articular injection of Synolis VA® for the overuse knee syndrome in sportsmen decrease the pain during spots and day-living activities by measured the improvement of knee symptoms through the KOOS score: - The Knee injury and Osteoarthritis Outcome Score: Evaluate Symptoms + Stiffness subtotal, Pain, Function, daily living, sports and recreational activities and quality of life. Each variable has a percentage score from 0 to 100%, at the end the results are averaged, obtaining a final percentage where 100% means a healthy knee with out discomfort. As the percentage approaches 0%, the severity of knee discomfort or injury increases.
Efficacy of Hyaluronic Acid With Sorbitol (SYNOLIS VA) in Overuse Knee Syndrome Assessed With the International Knee Documentation Committee Score (IKDC)	Baseline, 15 days, 3 months, and 6 months	To evaluate the effectiveness of two intra-articular injections of Synolis VA in improving knee functionality in athletes with overuse knee syndrome, the International Knee Documentation Committee (IKDC) Scale was used. This validated tool assesses knee function, symptoms, and the ability to perform sports-related activities. It consists of individual items evaluating pain, stiffness, swelling, instability, daily physical function, and athletic performance. While the scale's raw score ranges from 0 to 87, results are converted into a percentage format, where 87 corresponds to 100% functional capacity-the best possible knee function-and 0 represents the worst condition."

Secondary Outcome Measures

Name	Time	Method
Safety of Hyaluronic Acid With Sorbitol (SYNOLIS VA ®) in Overuse Knee Syndrome by the Number of Adverse Effects in Participants.	6 months	Evaluate the SYNOLIS VA ® safety after two doses of intra articular injection by tracking the number of patient withdrawals and their adverse events including: skin irritation, knee redness, local pain for more than 24 hours, edema for more than 48 hours and itching at the application site.
Six-Month Functional Improvement in Knee Function (IKDC and KOOS) in Athletes With Overuse Knee Syndrome With Elevated BMI Following Synolis VA Injections	6 months post-treatment	This measure evaluates the change in knee function over a six-month period in athletes with an elevated body mass index (BMI \> 25) diagnosed with overuse knee syndrome and treated with intra-articular injections of Synolis VA®. Two validated patient-reported outcome instruments are used: the International Knee Documentation Committee Subjective Knee Evaluation Form (scale: 0 = poorest function, 100 = best function) and the Knee Injury and Osteoarthritis Outcome Score (scale: 0 = worst outcome, 100 = best outcome). Higher scores indicate better knee functionality. Baseline scores are compared with six-month scores to assess functional improvement.
