Osteoarthritis, also known as osteoarthrosis, degenerative arthritis or degenerative joint disease, is a degenerative disorder arising from the biochemical breakdown of articular cartilage in the synovial joints. It commonly affects the hands, hips and knees.


  • At the time of presentation, the patient already underwent 6 joint replacement surgeries. Family history was unremarkable.[ncbi.nlm.nih.gov]

  • At the same time, the joint capsule becomes thicker and more synovial (lubricating) fluid is manufactured which makes the joint swell. In addition to cartilage degeneration, bony spurs grow causing inflammation in the surrounding tissues.[netdoctor.co.uk]
  • The exam may show: Joint movement that causes a crackling (grating) sound, called crepitation Joint swelling (bones around the joints may feel larger than normal) Limited range of motion Tenderness when the joint is pressed Normal movement is often painful[nlm.nih.gov]

  • Eventually, cartilage loss manifests as joint-space narrowing. Primary osteoarthritis is most commonly seen in the hands.[emedicine.com]
  • Key radiographic features are joint space narrowing, sclerosis, and osteophytosis. If all three of these findings are not present, another diagnosis should be considered.[radiopaedia.org]
