Abstract:
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.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
