I might have torn my meniscus so will i need surgery to fix it?

Arthroscopy can help: Meniscal tears that are symptomatic, whereby pain and mechanical symptoms of catching and painful giving way of the knee persists despite adequate rest, therapy, icing and potential use of NSAIDS (Motrin, etc.), often require arthroscopic surgery to either repair or debride (akin to trimming a hang nail back to a smooth rim) the tron portion of the meniscus.
