### Patient: Hi Doctor, I have been experiencing knee weakness, stiffness or tightness along with elbow and joint pain. Do you have any idea what could be causing this?
### Doctor: Yes, it sounds like you have chondromalacia of the patella which is when the cartilage under your kneecap softens and deteriorates, causing pain and weakness. We'll need to do some tests to confirm the diagnosis and discuss treatment options.
