About

The objective of this clinical trial is to verify the effectiveness of polyvinyl pyrrolidone collagen in all patients with symptomatic gonarthrosis grades II-IV in patients over 40 years of age. The main objectives that this study aims to answer are the following:

- Document the effectiveness of intra-articular polyvinylpyrrolidone collagen in the treatment of symptomatic gonarthrosis.
- Compare the intensity of pain, the degree of stiffness and functionality of the joint, prior to application and one month after the therapeutic intervention.
- Identify demographic, clinical and therapeutic factors that influence the effectiveness of intra-articular PVP collagen in the treatment of symptomatic gonarthrosis.

Patients diagnosed with symptomatic gonarthrosis Grade II-IV, referred to the Physical Medicine and Rehabilitation service within 3 months, will be selected. Two study groups will be assigned: GROUP those who received intra-articular infiltration of PVP Collagen, GROUP B: patients who received conservative treatment. Through rehabilitation with a home program for one month, in both cases, ENA and the WOMAC scale will be evaluated at the beginning of the study and after 4 weeks.
