What is Arthritis?

Arthritis & Osteoarthritis

Various types of arthritis may affect the knee joint.

Osteoarthritis, a degenerative joint disease that affects mostly middle-aged and older adults, may cause the breakdown of joint cartilage and adjacent bone in the knees.

Rheumatoid arthritis, which causes inflammation of the synovial membrane and results in excessive synovial fluid, can lead to pain and stiffness.

Traumatic arthritis, arthritis due to injury, may cause damage to the cartilage of the knee.
