Hi a year ago i tore my knee ligiment (acl?) in thai boxing training. i could not walk for a couple of weeks and it slowly got better. one year on i can now walk and run but its still very weak. it "gives way" if i do any spinning kicks. (supporting leg is the injury) i was just wondering if i would need surgery or i should just go to a physio. its really getting me down i just want to get training agian. if any could somehow give me a diagnosis (its hard over the internet i know) it would be amazing.
