I'm 53 years old. I have got  meniscus tear after a twist. My MRI reports  that I  have got: 1. Bucket handle tear involving entire length of lateral meniscus which otherwise appears to have discoid configuration. 2. complex tear involving posterior horn and posterior root of medial meniscus,  along with formation of few small parameniscal cysts. I am doing all activities without any problem. I have no swelling . I get pain at times for 2 or 3 min.  Sometimes even after 4 or 5 days or after a week. sometimes 2 or 3 days consecutively.  In June, I twisted my right knee.  During this period I was even without pain for 10 days or 2 weeks. Kindly advise me . 

Summarized question: Should I leave a meniscus tear untreated if it does not cause problems?
