[Knee joint cyst].
Ninety cases of knee joint cysts were treated surgically. This included 50 patients with rheumatoid arthritis, 22 patients with degenerative-deforming changes, ten children with true cysts, and eight ones with post-traumatic cysts. Double-contrast X-ray examination with Lipiodol Ultra-fluid and air is of the best diagnostic value. All cases of knee joint cysts were treated surgically with a careful plastic closure of cyst gate. For this purpose the authors used the arcus tendon of the semi-membranous muscle. In cases of rheumatoid arthritis and degenerative changes cyst removal was preceded by synovectomy of the knee joint. Early and remote were good, no recurrence was observed.
