We have performed synovectomy of the knee joints for about 50 cases and recently a follow up study was done in 19 cases. This report will be presented some radiologic changes after synovectomy of these 19 cases.
The age of study group ranged from 5 to 66 and follow up period from 3 to 15 years. Original diseases of study group consisted of rheumatoid arthritis, osteoarthritis, pigmented villonodular synovitis, chronic synovitis, hemoangioma and tuberculosis. Radiologic findings used for check-up point and comparison in pre and post operation were rarefaction, periosteal elevation, narrowing of joint space, erosion, subchondral structural changes and spur formation.
The results we obtained as followed;
(1) Post operative radiologic changes were minimal in younger group and growth of bones were normally observed.
(2) In cases showed the minor radiologic changes in preoperation, the less changes observed in post operation.
(3) In cases of osteoarthritis, radiological changes increased gradually by aging but did not turn for the worse progressively by synovectomy.
