Complete arthroscopic synovectomy in management of recalcitrant septic arthritis of the right knee joint. The patient is in supine position with the legs spread. (A) Posterolateral knee endoscopy is performed with the posterolateral (PLP) and lateral (LP) portals. (B) The lateral portal is the viewing portal, and the posterolateral portal is the working portal. The dissection should not be posterior to the biceps femoris tendon to avoid injury to the common peroneal nerve. The medial head of the gastrocnemius (MG) is identified and the posterolateral capsule (PLC) of the knee joint can be seen anterior to the gastrocnemius. The star indicates the point of posterolateral capsular portal. (C) A 4.0-mm Wissinger rod into the posterolateral skin portal. (D) The Wissinger rod (WR) passes through the posterolateral capsular portal. (BFT, biceps femoris tendon; FH, fibular head; LCL, lateral collateral ligament; LJL, lateral joint line.)
