Fig 1 Endoscopic fasciotomy of the superficial and deep compartments of the right leg. The patient is in supine position with the legs spread. (A) The medial edge of tibia (T), medial edge of the Achilles tendon, and the inferior border of the medial gastrocnemius muscle (MG) are marked. The portal is located at the proximal medial corner of the Achilles tendon. (B) The deep fascia is incised open at the portal incision. (P, portal; TA, achilles tendon.)

Fig 2 Endoscopic fasciotomy of the superficial and deep posterior compartments of the right leg. The patient is in supine position with the legs spread. (A) The subcutaneous tissue is retracted dorsally by means of a Deaver retractor. A malleable retractor is inserted under the deep fascia. The deep fascia over the medial gastrocnemius muscle is released by a SuperCut scissors under endoscopic visualization. (B) Endoscopic view shows release of the deep fascia (F). (M, malleable retractor; P, portal; R, retractor; S, scissors.)

Fig 3 Endoscopic fasciotomy of the superficial and deep posterior compartments of the right leg. The patient is in supine position with the legs spread. (A) The Achilles tendon and the medial gastrocnemius muscle are retracted laterally to expose the deep posterior compartment. Deep posterior compartment release is performed with an endoscopic scissors (ES) under endoscopic guide. (B) Arthroscopic view shows release of the fascia over the flexor digitorum longus muscle (FDL), which is medial to the tibial neurovascular bundle (TNVB). (P, portal; R, retractor.)

Fig 4 Endoscopic fasciotomy of the superficial and deep posterior compartments of the right leg. The patient is in supine position with the legs spread. Fasciotomy of the flexor hallucis longus muscle can be performed via the portal (P) by turning the arthroscope (Ar) and endoscopic scissors (ES) distally (A) and laterally (B).
