What Is Knee Cartilage?
Cartilage is a type of connective tissue that is present throughout the human body, particularly in the joints where it forms a protective layer covering the surfaces of the tibia (shinbone), femur (thighbone), and the undersurface of the patella (kneecap). It is less rigid than bone but still firm enough to absorb stress and protect the joint. When an injury to the knee cartilage occurs due to trauma, overuse, sports injuries or aging, it can lead to chronic knee joint pain and swelling. The severity of the injury can range from mild softening of the connective tissue to torn cartilage that exposes underlying bone. Patients with knee cartilage injuries may also experience “loose bodies” floating within the joint, which can cause mechanical problems such as catching and locking. Cartilage damage can also result in continued swelling, pain, and limited range of motion, ultimately affecting the knee’s overall function.
What Are Symptoms Of A Knee Cartilage Injury?
To identify a cartilage injury, the most common symptoms are persistent knee joint pain and swelling. In addition, patients with loose bodies may also experience mechanical symptoms such as catching and locking of the joint. These symptoms may affect the knee’s full range of motion and can lead to functional limitations. It is essential to seek medical attention if these symptoms persist or worsen over time, as untreated cartilage injuries can lead to more severe complications such as osteoarthritis.
