Various degrees of first metatarsophalangeal joint arthrofibrosis frequently occur in patients with bunion surgery or big toe trauma. In those patients with functional limitation who fail to respond to conservative treatment, surgery is indicated. We describe here an arthroscopic approach to first metatarsophalangeal release that is designed to improve functional results. Dorsomedial and dorsolateral portals are established at the medial and lateral sides of the extensor hallucis longus tendon. Through these 2 portals, the dorsal capsule is released and the medial and lateral joint gutters can be cleared up. The metatarsosesamoid compartment is approached through the straight medial portal and the working portal, the latter of which is located 4 cm proximal to the joint line between the abductor hallucis tendon and the medial head of the flexor hallucis brevis. Under visualization through the medial portal, adhesions around the sesamoid apparatus can be debrided with a shaver through the working portal. This completes the release of joint circumference and improves the motion range of the joint.
