2. Fig 1
Resection of prominent posteromedial process of left talus by posterior ankle arthroscopy. (A) The posterolateral portal (PLP) is located just posterior to the peroneal tendons and at the level of the ankle joint. (B) The posteromedial portal (PMP) is located anterior to the posterior tibial tendon and at the level of the ankle joint.

4. Fig 3
Resection of prominent posteromedial process of left talus by posterior ankle arthroscopy. The posterolateral portal is the viewing portal. The prominent posteromedial talar process (TP) is resected at its posterior end by an arthroscopic acromionizer via the posteromedial portal.

5. Fig 4
Resection of prominent posteromedial process of left talus by posterior ankle arthroscopy. The posterolateral portal is the viewing portal. The flexor hallucis longus (FHL) tendon is examined. (S, inflamed synovium around the FHL tendon; TP, posteromedial talar process.)

6. Fig 5
Resection of prominent posteromedial process of left talus by posterior ankle arthroscopy. The posteromedial portal is the viewing portal. The residual impinging bone of the posterolateral part of the talus (T) is resected by an arthroscopic acromionizer via the posterolateral portal. (Tib, tibia.)

7. Fig 6
Resection of prominent posteromedial process of left talus by posterior ankle arthroscopy. (A) Preoperative lateral ankle radiograph shows the prominent posteromedial talar process (arrowhead). (B) Postoperative radiograph shows that the posteromedial talar process is resected. (T, talus.)
