Hello sir, i am aged 60 years and had ACL tear grade-3 on my left knee about six months back. No surgery has been done but rehabilitation has been done, lot of exercises (with 3 kg weight) and stationary cycling. do not have any instability issues, Have been advised b knee brace(Do joy full for ACL brace), which i am using since injury. But i am not satisfied with the brace even though it is very expensive brace. This brace tends to slip in spite of proper tightening and wearing.on one occasion it slipped and cause hurt (medieval pain which got cured after 45 days) can you please advise me any other good quality brace which will perform better. Do not any issues even if it had to be imported. best regards
