What is Osteo-arthritis?
Osteo-arthritis (OA) is most common form of arthritis affecting
mostly the Knees.
How common is Osteo-arthritis?
Osteo-arthritis is most affecting one out of eight people between
the ages of 18 and 79. According to Arthritis Foundation,
approximately 16 million Americans suffer from Osteo-arthritis,
three times as many women as men. Osteo-arthritis has increased
recently due to sedentary lifestyle as people walking less, are more
over-weight, eat fast food, junk food etc and are not keeping the
muscles toned by doing quality exercises. so they are bound to
suffer from knee disorders which is simply gravity and weight
leading to wearing-out of cartilages. Also more Osteo-arthritis is
seen due to increase in awareness and life expectancy, and increase
in treatment modalities.
At what age does osteo-arthritis occur?
Most common age for osteo-arthritis is after 60-65 years and this is
a normal course of events like losing hair or getting grey hair. But
when it occurs in the late 40's or early 50's, then this is due to
How does Osteo-arthritis occurs?
Cartilage contains fluid and elastic tissue, and functions to reduce
friction as the joint moves. It acts as a shock absorber and as the
sliding surface that covers the ends of bones. Osteo-arthritis
results from chemical changes in the cartilage that cause it to
break down faster than it can be produced.
Knee starts degenerating with age which is more when there is extra
weight, diabetes. gout, autoimmune diseases, etc. Gradually the
smooth and shiny cartilage between the two bones of the thigh and
leg starts wearing out and the bone strikes bone and this leads to a
lot of pain and stiffness, especially early in the morning. There is
stiffness in the morning and patient requires to take a few steps
before he can walk properly.
Previous infection of the joint may predispose to Osteo-arthritis by
altering the chemical makeup of cartilage. The weakened cartilage
causes it to wears out due to which bone rubs against bone.
ultimately leadings to Osteo-arthritis and increased bone density,
which may result in bones that are less able to absorb impacts and
to protect cartilage from trauma.
What treatment are available for
Till date there has been no known cure for Osteo-arthritis. The
treatments available were:
- Decrease the pain with medicines, Herbs and Heat or
- Supportive measures like Weight loss, Rest, Nutrition
/ food supplements
- Assistive devices to make life easier.
- Exercise and Paraffin bath etc
- Surgical treatments for severe Osteo-arthritis with
significant loss of cartilage. These include :
- Arthroscopy for pain relief or to fix the joint
- Osteotomy to correct joint deformity
- Arthrodesis to immobilize joint by fixing bones
- Joint replacement for severe joint deterioration
Surgery for Osteo-arthritis is usually considered i the patient is
fit for it. However it may need several months of rehabilitation
after surgery and an artificial joint may only last for 10 to 20
years when it may wear out and need repeat surgery.
