I am a women in my 30's and I have been diagnosed with a non displaced tear in the posterior horn and body of medial meniscus in MRI scan Is it necessary to undergo surgery Could it heal by itself?

Unfortunately, damaged cartilege can't heal by itself as it has no blood supply. ÂThe joint may settle down with anti inflammatory medication and ultrasound treatment from a physiotherapist, but this approach rarely works well. ÂThe only real option is surgery, frankly. ÂThese days this operation would be done by keyhole surgery.
