Suffering from knee pain - strange symptoms!

Thanks guys My surgeon has been really good. I go in for my first round of surgery next Thursday - just an Arthroscopy to get rid of all the fragments and to try and clean up the lesion. After that I'll be waiting a few weeks and then going back in for an ACI. The surgeon says that I'm going to have a much better chance of getting the lesion fixed properly and avoiding OA later in life if I get this done straight away. It means 6 weeks on crutches and open knee sugery but I'm keen to get the use of my knee back! At the moment I'm getting a lot of painful locking and giving away. It hurts plenty! I shall continue to keep every posted.

After visiting another 2 doctors and getting an X-Ray that showed nothing, I was finally sent in for an CT Scan that showed that I have an Osteochondral Defect about 2 cm long on the weight bearing part of me knee. I have three loose bodies floating inside of my knee - one of which looks like a bone chip and two of which look to be fairly large chunks of cartilage.

One of the cartilage chunks keeps popping out from under my kneecap - that is the lump I keep feeling. At least, that is what the doctor thinks.

I'm still in excruiting pain, especially when I'm walking - although the pain can come at any moment and is awful.

All three doctors gave me a different diagnoses because my symptoms kept changing depending on where the loose bodies were currently floating. The doctors also really seemed to doubt the symtoms and pain I was describing because the symptoms did keep vanishing and then reappearing.

I'm now terrified because I'm being referred on to a surgeon. I'm not a fan of doctors or hospitals as it is, and I've never had any good experiences with surgery. I will keep everyone updated.

I've been suffering from knee pain for the last 2 weeks. I did not have an accident that caused this, my knee just felt 'out' one day and it started hurting if I put weight on it. I did at one stage kneel down on it and really, really hurt it (a very sharp horrible pain)...but I don't remember hearing any popping sounds or anything like that. Just excruiting pain. After that I had mild swelling (but not much) and I couldn't straighten it for a day or two.

My knee feels 'out' and I get severe stabbing pain occasionally...usually when walking up stairs or if I put pressure on it without bracing the knee first. When I first injured it I could not straighten my knee completely or bend it properly. I can now straighten it but the knee does not flex properly and I can't lock it. I can bend my knee at a gentle angle (usually) but cannot bend it to a large degree, and at times when it feels 'out' I cannot bend it at all. When my knee feels 'out' I get painful lumps above my knee or on the side of it. It feels like a knotted muscle but hurts terrible if I touch it or rub it. Usually standing and attempting to lock my knee will make my knee feel more 'in' and the lump or whatever it is will disappear.

I have torn my cruciate ligament twice when I was a kid and have had my knee give way from time to time, but have never had anything like this pain before. I did go to the doctor initially and after a very very brief examination she told me that she thought I had hurt the meniscus in my knee and that I would need surgery. She told me to wear a knee brace for two weeks to see if it helped. My symptoms have changed since I saw her then to the ones I described above. I really do not want to have surgery and although I don't usually question doctors I'm not sure what the 'out' feeling is and what the knots are that appear above or around my knee when this happens.

I am a 26 year old female, I'm fit and am a healthy weight. My exercise is walking and swimming - all very gentle since I have a bad back.

Any info is really, really appreciated!
