Osteoarthritis is a disability

KOOS is developed as osteoarthritis is a disability instrument to assess the patients opinion about their knee and associated problems. FAOS was developed to assess the patients opinion about a variety of foot and ankle-related problems. Osteoarthritis mostly affects cartilage, the hard but slippery tissue that covers the ends of bones where they meet to form a joint. Healthy cartilage allows bones to glide over one another.

In osteoarthritis, the surface layer of cartilage breaks down and wears away. This allows bones under the cartilage to rub together, causing pain, swelling, and loss of motion of the joint. Over time, the joint may lose its normal shape. Also, small deposits of bone — called osteophytes or bone spurs — may grow on the edges of the joint. Bits of bone or cartilage can break off and float inside the joint space.
