I met with an accident 6 months ago in which I had severe knee injury. Doctors confirmed that there is no fracture or ligament tear, but they suspect a meniscus tear in the right knee. I have been going through medication including vitamin supplements like depura 60k, for the past six months. Is it safe and advisable to start doing exercises to strengthen my knee. Will this help to cure my knee? And by exercises I mean jogging, sit-ups, lunges etc. I would like to have some advice!
