Fig 1 Arthroscopic resection of the too-long anterior process of the right calcaneus. (A) The lateral midtarsal portal (LP) is the viewing portal. The dorsolateral midtarsal portal (DLP) is the working portal. (B) The lateral midtarsal portal is located at the plantar lateral corner of the calcaneocuboid joint. The dorsolateral midtarsal portal is at the junction between the calcaneocuboid and talonavicular joints and at the level of the calcaneocuboid joint line.

Fig 2 Arthroscopic resection of the too-long anterior process (TLAP) of the right calcaneus. The lateral midtarsal portal is the viewing portal. Arthroscopic view after resection of the capsules of the talonavicular and calcaneocuboid joints shows the impinged lesion (ImL) at the plantar medial aspect of the navicular (Nav). (Cu, cuboid.)

Fig 3 Arthroscopic resection of the too-long anterior process (TLAP) of the right calcaneus. The lateral midtarsal portal is the viewing portal. The TLAP is resected by an arthroscopic burr via the dorsolateral midtarsal portal. (Cu, cuboid.)

Fig 4 Arthroscopic resection of the too-long anterior process (TLAP) of the right calcaneus. The lateral midtarsal portal is the viewing portal. After resection of the TLAP, the soft tissue plantar to the tarsal bones can be seen through the space between the talonavicular and calcaneocuboid joints. (Cal, calcaneus; Cu, cuboid.)

Fig 5 Arthroscopic resection of the too-long anterior process (TLAP) of the right calcaneus. Oblique foot radiographs of the illustrated case. (A) Preoperative radiograph shows that the TLAP (arrowhead) impinges the navicular. (B) Postoperative radiograph shows that the TLAP was excised.
