<s>[INST] A month or two ago I fell playing basketball and it made a popping noise almost like it came out of place. my leg was weak feeling and I put ice on right away I could walk and everything okay still just week feeling. the next day my knee was twice the size of what it normally is. The swelling immediately went down the next few day but now everytime I bend to a certain point it like catches on something and lately it s been hurting doing simply things like getting up or walking down stairs and I ve also started running which might be part of it. I was looking at the runners knee and another diagnosis but I m still not positive but I want to know soon so I can get it healed as soon as I can! [/INST] His a precaution you must stop all activity of knee like walking, stairs,gaming-take complete rest, wear a knee brace and take anti-inflammatory and analgesics tablets. Consult an orthopedic surgeon and have a knee MRI done.-Meniscal tear and cruciate ligaments tear is a common injury and need specific treatment after diagnosis-sometimes surgeons prefer to do surgical intervention to correct they neglect ow may be harmful to knee </s>
