  1. Define and describe osteoarthritis
    • Most common type of arthritis, affecting synovial joints
    • Probably a multifactorial process with mechanical/cellular damage
    • Whole joint affected, but particularly hyaline cartilage damage
  2. Describe the pathological features of osteoarthritis
    • Enthesophytes: projection at bone/tendon interface
    • Chondrophytes: Cartilage projection
    • Osteophytes: Bony projections into joint space
    • Periarticular structures
    • Cartilage structure alteration
    • Joint space narrowing
    • Inflammation
  3. List 6 risk factors predisposing to osteoarthritis
    • Obesity
    • Family history
    • Gender (women)
    • Hypermobility
    • Joint trauma
    • Occupation (manual)
    • Exercise
  4. List 6 clinical features of osteoarthritis
    • Joint pain/tenderness
    • Joint stiffness/loss of function
    • Joint instability
    • Crepitus
    • Effusion
    • Muscle wasting
  5. Outline the use and risks of amniocentesis and chorionic villus sampling
    • Amniocentesis: Tests amniotic fluid for fetal DNA karyotyping. Performed 15-20th week. Miscarriage 1/200
    • Chorionic villos sampling: DNA karyotyping. Performed >8 weeks. 1/100 risk of miscarriage
