Arthritis - Knee

Arthritis in the knee is a condition that affects more than four million Americans annually, occurs when degenerative changes develop in the cartilage that lines the knee joint. This condition, which is more commonly seen in women, is characterized by pain in the front part of the knee (behind the patella, or kneecap) that typically worsens when the patient walks on inclined terrain, goes up and down stairs, knees, squats, and rises from the sitting position (while walking on level ground is often unaffected).
