It has been over 3 months now since my I tore my MCL during Jiu-Jitsu. I’ve been taking good care of it. I still wear a brace during practice. It is still tender in spots. Some times I get a weird twinge of pain that pluses down the side from having it bent too long. Over all it looks like everything is mending. The book I got to help me strengthen it, Treat Your Own Knees – Simple exercises to build strength, flexibility, responsiveness, and endurance, has helped but really it only has 4 exercises and could be condensed to one page. The book gives far more detail and education then I need. But I still recommend it. It has good diagrams that explain the inner working.
