Conditions that may cause knee problems

Problems not directly related to an injury or overuse may occur in or around the knee.

  • Osteoarthritis (degenerative joint disease) may cause knee pain that is worse in the morning and improves during the day. It often develops at the site of a previous injury. Other types of arthritis, such as rheumatoid arthritis, gout, and lupus, also can cause knee pain, swelling, and stiffness.
  • Osgood-Schlatter disease causes pain, swelling, and tenderness in the front of the knee below the kneecap. It is especially common in boys ages 11 to 15.
  • A popliteal (or Baker's) cyst causes swelling in the back of the knee.
  • Infection in the skin (cellulitis), joint (infectious arthritis), bone (osteomyelitis), or bursa (septic bursitis) can cause pain and decreased knee movement.
  • A problem elsewhere in the body, such as a pinched nerve or a problem in the hip, can sometimes cause knee pain.
  • Osteochondritis dissecans causes pain and decreased movement when a piece of bone or cartilage or both inside the knee joint loses blood supply and dies.
