Chondromalacia patella (knee pain) is the softening and breakdown of the tissue (cartilage) on the underside of the kneecap (patella). Pain results when the knee and the thigh bone (femur) rub together. Dull, aching pain and/or a feeling of grinding when the knee is flexed may occur.

Chondromalacia patella is one of the most common causes of chronic knee pain. Chondromalacia patella results from degeneration of cartilage due to poor alignment of the kneecap (patella) as it slides over the lower end of the thighbone (femur). This process is sometimes referred to as patellofemoral syndrome.

A knee sprain refers to torn or overstretched ligaments, the tissues that hold bones together. If you have a sprained knee, the structures within the knee joint that connect the thigh bone to the shin bone have been injured. A knee sprain is painful and can create other problems over time, including arthritis.
