Active Release Technique help?

It is very effective for soft tissue treatments. I got it after I had ACL surgery and they used a piece of my hamstring tendon for my new ACL. My hamstring was very tight afterwards and just felt like it always had a charlie horse. I got ART on my quads, hamstrings, and calves. It was AMAZING after the first treatment my hamstring felt 98% better. If the problem you have is muscluar ART will help. If its ligaments then ART may help but there is a technique called graston that works really well for ligament injuries.
