Signs and Symptoms


  • Symptomatic – NICE states diagnose as OA if >45 years, activity related joint pain, No (<30 minutes) morning stiffness – to differentiate to RA. May also use pain scored.
  • Labs are normal
  • X-Ray – Scoring system to quantify based on
    • Joint space (cartilage thickness)
    • pathology e.g. osteophytes, subchondral bone thickness.
  • MRI – Can visualize cartilage to quantify thickness of volume.


  • Clinical management
    • Exercise, weight lost, aids such as walking stick or insoles.
    • Walking, water aerobics, stationary bike riding along with strengthen training (lifting weights: helps strengthen muscles around the joint)
    • ROM: improves the mobility of the joint and decreases stiffness.
    • It is important patients with OA avoid high impact exercises that will increase stress on weight bearing joints such as running/jogging, jump rope, tennis, or any type of exercise with both feet off the ground.
  • Pharmaceutical treatment
    • Pain killers and anti inflammatory
    • Voltaren Gel (Diclofenac)
    • Tylenol Arthritis
    • Mobic
    • Meloxicam
  • Injections
    • Steroids
  • Surgical treatment
    • Joint replacement, affected joint structures removed with prosthesis. Increases mobility, reduces pain, major surgery and prosthesis has limited life.
