COMPARATIVE STUDY OF THE EFFICACY OF HYALURONIC ACID, DRY NEEDLING AND COMBINED TREATMENT IN PATELLAR OSTEOARTHRITIS

Study Overview
=================
Brief Summary
-----------------
Randomized clinical trial in patients with knee osteoarthritis. Sixty patients will be evaluated, divided in three groups (20 in each). One group A will be treated by dry needling in the vast internal, other group B will be treated with a standardized treatment protocol (electrotherapy and manual therapy), and group C will be treated with hialuronic acid. The investigators want to observe which technique is the most effective in osteoarthritis.

| Visual Analog Scale | Pain 0 maximum pain score---------10 minimum pain score | 1 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
