What causes grinding in the knee?

The crunching you hear likely is due to the cartilage in your knee becoming rough, so the bones cannot slide as easily in the joint as they normally do. Knee crepitus typically happens when the knee is bent, such as when you are squatting, going up or down stairs, or rising from a chair.

Which bones attach to the patella?

What is unique about the patella?

The patella is a roughly triangular shaped bone called a sesamoid bone from the Latin sesamun “sesame seed”. It is the largest of this type of bone in our body as compared to the tiny sesamoid bones in say our foot.

Does the patellar grow back?

The authors conclude that a harvested patellar tendon doesn't return to normal. It does remodel itself even after two years, but the tissue quality is lower than normal.
