I would suggest you see a physiotherapist for appropriate rehabilitation and treatment following a medial meniscal tear, lateral meniscal tear and acl tear. Generally knee arthroscopy may be advised if you do not respond appropriately to conservative measures including appropriate physiotherapy for a few weeks and surgery is likely to improve your outcome. I would suggest discussing your questions with your physiotherapist. In the mean time you may be interested in checking out the above links for detailed information on these conditions.

Hope that helps,
