Quadriceps tendon - knee problem

Had a problem for a few months with the top of my knee and kneecap swelling, so went to the doctors on saturday to get it checked out.

Was told by him that I'd overstrectched the prepatella tendon (which I can't find any document of, so presumed he meant the quad tendon), and that it kept inflaming and filling with fluid making it sore and swollen, and said it'd probably take about 6 months to get over.

He said I was fine to do sports on it, so long as I wore a proper support.

Was just looking for a recommendation on a knee support for that sort of injury that I can wear while snowboarding.

Chhheeeeers.

As your post is a little vague, it's hard to give an accurate diagnosis/advice online. I'd suggest you see a physio (if your GP can refer you) as the pain has been there for a few months and as far as I know (please correct me if I'm wrong more experience physios), GPs can sometimes tend to diagnose musculoskeletal problems that they aren't very experienced in because they are triage, so always better to get it checked over by someone with more thorough knowledge.

Sounds like there's definitely an inflammatory component due to the recurrent swelling and pain you're getting....seems to be patellofemoral pain (to do with the kneecap). Possibly bursitis? Bursae are small sacs of fluid that cushion the joints and can become inflamed and swollen due to direct trauma or abnormal forces (e.g. if your walking pattern is altered/ muscles are slightly imbalanced). Have you tried any supports or worn any compress like tubigrip on your knee? If so, does this help? Might be all you need to keep going with things, but I'd stand by getting a second opinion and seeing a physio - may be that they can give you some treatment or advice that will speed things along for you.

1. Is there any pain?
2. What sport are you likely to play?

agree with physiofi - differential diagnosis wide as could be a number of things and i think best to get hands on assessment and treatment plan as been going on for so long now
