Dear XXXXXXX

Thanks for posting your query.

You must have hurt your XXXXXXX structures in knee while playing, which are anterior/posterior cruciate ligament, medial/lateral collateral ligament, medial and lateral menisci, joint capsule, synovium, crossing muscles, bone cartilage and bone itself. It needs proper clinical examination and relevant investigations to diagnose which among these is hurt. Your x-rays are excellent and show no bony and other gross abnormality whatsoever. It leaves us with possibility of ligament, meniscus, capsule or synovial injury. These are best visualized on MRI (Magnetic Resonant Imaging).

I hope your physician examined you well before prescribing medicines. If it gives you relief you may resume sports after a gap of 1 or 2 weeks. As you rightly mentioned, a pair of knee supports can add to stability. But that again depends on your exact condition. If you don't get relief, proceed with MRI.

In my opinion, try to refrain from tennis for a while. Begin sports gradually and warm up before every game. Not to forget proper sports gear is must viz attire and shoes. If you notice instability while walking or running, visit your orthopaedician at earliest.

Hope you find this answer informative. Please get back to us for more queries; I'm available for follow up.
Regards

Dear XXXXXXX

Thanks for getting back.

Cartilage defects unless large are not visible on x-rays. Your xrays are absolutely fine. Both compartments are equal and in normal range. Cartilage defects are noted on MRI so if you want to confirm please get an MRI done.

Regards.
