The most common form of arthritis in the knee is called Osteoarthritis and is a degenerative decease. It mostly occurs in people over 50 years of age but can affect younger people as well.
Osteoarthritis causes the cartilage in the knee joint to gradually wear off causing it to become frayed and rough with the protective space between the bones to decreases. This results in the bones rubbing together and forming a painful bone spur.
Arthritis of the knee can cause tenderness, stiffness and swelling in the joint. Rheumatoid arthritis can cause more severe pain than osteoarthritis. This form of arthritis usually affects the same joints on both sides of the body, whereas osteoarthritis is usually asymmetrical.
Knee arthritis can make it hard to do many everyday activities, such as walking or climbing stairs.
Osteoarthritis is a degenerative, “wear-and-tear” type of arthritis that occurs most often in people 40 years of age and older, but may occur in younger people, too. Osteoarthritis develops slowly and gradually gets worse over time.
In osteoarthritis, as the cartilage wears away, it becomes frayed and rough, and the protective space between the bones decreases. This can result in bone rubbing on bone, and produce painful bone spurs.
Rheumatoid arthritis is a chronic, autoimmune disease that is symmetrical in nature, meaning it usually affects the same joints on both sides of the body. The immune system attacks its own tissues and damages normal tissue. In rheumatoid arthritis the synovial membrane that covers the knee joint begins to swell, resulting in stiffness and knee pain, particularly in the mornings.
Posttraumatic arthritis s developed after an injury to the knee. An injury, such as a broken bone can cause damage to the surface of the joint and lead to arthritis long after it happened. A knee joint suffering from arthritis can be painful and develops slowly over time. Ligament injuries and meniscal tears can cause instability and additional wear on the knee joint, which over time can result in arthritis.
Surgery may be considered if non-surgical treatments fail to work.
