    Abstract:
    For successful arthroscopic total synovectomy in rheumatoid arthritis of the knee, proper sequential steps are required. First, we resect hypertrophied synovial villi on the intercondylar notch to make a gateway for the posterior compartments. We also perform synovectomy at the posterolateral chamber because of the narrower space of the chamber than that of the posteromedial chamber and the intra-articular crowding due to swollen synovial villi with the passage of operation time. Special care should be taken not to overlook both posterior back corners and roofs, which cannot be seen through the transnotch view, even with a 70 degrees arthroscope. The posterior back corners and roofs can be visualized by using the trans-septal approach technique. In this approach, we prefer to perforate the posterior septum in the posterolateral-to-posteromedial direction to avoid damaging the neurovascular structures because the structures are located just behind and lateral to the midline septum and the posteromedial capsule bulges a bit more posteriorly than the posterolateral capsule. Attention is then directed to the medial, lateral, and suprapatellar compartments, and finally the retropatellar compartment. Our surgical steps are safe and effective for complete synovectomy of the rheumatoid arthritic knee joint and other synovial disorders.
