How can muscles and torn ligament be repaired?

 
There is nothing that you can do to repair muscles and torn ligaments. If the tear or strain is minor, the body will repair it naturally. You can help the process by giving the affected region adequate rest and other such management as taking anti inflammatory drugs for a short period. More severe tears may need to be corrected by surgery if possible. Surgical treatment may not be possible in all cases. Even if it can be done, surgical treatment will not bring the torn ligament or muscle back to original condition. There will always be a defect and you will need to take care while stressing that area.
