What is the Knee Arthritis?
The femur, fibula, tibia and patella make up the knee which is surrounded by muscles, ligaments and tendons that provide support and stability which allows you to move. Arthritis happens when the knee becomes inflamed and knee osteoarthritis is the most common type.
Knee arthritis happens when the cartilage in the knee becomes damaged and inflamed. Cartilage, a slippery, hard material that coats the ends of bones, allows bones to move together smoothly without rubbing each other. When the cartilage begins to wear down, the bones start to rub against each other. Patients then experience swelling, stiffness and pain.
Patients may first notice a popping or cracking feeling when they flex their knee. The pain may get worse when the move the knee. The stiff, sharp, gnawing pain may affect the range of motion.
The treatment may include lifestyle changes, physical therapy to strengthen the muscles around the joint, anti-inflammatory pain killers, patches and creams used around the affected area. If these treatments fail, a doctor may recommend injections that can provide instant relief.
