Hi! there is kind of nagging chronic inflammation / infection there and it needs orthopedic opinion!

Well, your problem is very common especially in young individuals and in such cases we generally do x-ray/USG or a fine needle aspiration biopsy for confirmation of the diagnosis. The possibilities come as follows:

1. a chronic abscess or synovitis: 60% of cases

2. an inflamed bursa 30 % of cases

3. loose bodies like fragments of patella or tendons 5 % cases

4. arthritis like erosive arthritis 5% cases

Therefore, you need rest of the joint, investigations and must see an orthopedic surgeon for possible line of management.

Wishing you good health!
