For arthroscopic preparation and exposure of the FH (right knee), the patient is placed in the supine position, with the knee secured in an electric leg holder. (A) The dorsolateral recessus can be observed through the posteromedial portal. (B) The posterolateral portal provides access to the capsular fibers (+) posterior to the PLT; these fibers are resected with a shaver (Excalibur, Arthrex) to expose the PLT (*) and the FH. (C) A radiofrequency electrode is used to carefully resect soft tissue until the FH is exposed. (D) Care should be taken to protect the peroneal nerve, which is located an additional 2 to 3 cm distally, as well as the popliteal nerves and vessels. (F, femur; FH, fibular head; PLT, popliteus muscle tendon; T, tibia.)
