Single-Dose Hybrid Hyaluronic Acid and Sodium Chondroitin with Rehabilitation for Sports Adults with Knee Osteoarthritis

: This observational case-control study aims to evaluate the efficacy of a single-dose intra-articular injection of a hybrid purified hyaluronic acid with high molecular weight and sodium chondroitin of biotechnological origin, combined with rehabilitation treatment, in sports adults with moderate to severe knee osteoarthritis. Additionally, the study incorporates isokinetic testing to assess muscle strength and functional capacity. The primary objective is to determine whether this combined treatment improves pain relief, functional capacity, and overall quality of life compared to rehabilitation treatment alone. Participants aged 18 to 50 years, diagnosed with knee osteoarthritis, will be recruited from clinics at the U.O.C. of Recovery and Functional Rehabilitation at A.O.U.P. P. Giaccone in Palermo. Participants will be divided into two groups: one receiving the hybrid hyaluronic acid and sodium chondroitin injection along with rehabilitation, and the other receiving only rehabilitation. The study will also utilize isokinetic testing to provide objective measurements of muscle strength and endurance.
