  • Common chronic joint condition. Primarily a disease of cartilage

  • Increasing evidence of inflammation in early osteoarthritis

  • The clinical hallmark is bony swelling of the affected join

  • Distinct pattern of joint involvement in primary OA:
    • distal interphalangeal joints (Heberden’s nodes)

    • PIP joints (Bouchard’s)

    • 1st carpometacarpal joint (CMC) — thumb base pain — pain taking lids off jars, turning on taps

    • acromioclavicular joint (AC) — tip of shoulder pain

    • hip — pain in groin and anteromedial thigh

    • knee (patello-femoral and tibio-femoral)

    • 1st metatarsophalangeal joint (MTP)

  • Secondary OA can occur at site of previous trauma or inflammation. Therefore OA affecting unusual sites e.g. MCP, wrist, elbow, glenohumeral joint, ankle — may need investigation to rule out secondary causes, e.g. pyrophosphate arthropathy

  • Cervical and lumbar spondylosis = OA of spine — affects facet joints predominantly. Associated vertebral osteophytes and disc space narrowing
