Osteoarthritis is the most common
What is it?
Osteoarthritis is a condition that effects your joints. The surfaces within your joints become
damaged so the joint doesn’t move as smoothly as it should. Some of the cartilage covering
the ends of the bone gradually roughens and becomes thin, an the bone underneath
thickens. All the tissues within the joints become more active than normal as if your body is
trying to repair the damage
What happens in osteoarthritis?
As if your body is trying to repair the damage. The bone at the edge of your joint grows
outwards, forming bony spurs called osteophytes.
The synovium (the inner layer of the joint capsule which produces synovial fluid) may
thicken and make extra fluid. This causes the joints to swell. The capsule and ligaments
(though bands that hold joints together) slowly thicken and contract as if they were trying to
make your joint more stable.
