The synovial changes in post-traumatic synovitis and osteoarthritis.

The histopathologic appearances of post-traumatic synovitis and synovitis of osteoarthritis cover a limited range of changes and have features in common. Electron microscopy yields information complementary to that given by light microscopy. With these techniques, based on sufficient material, histological analysis linked with clinical observation will permit some degree of differentiation between the two conditions.
