BACKGROUND: The anatomical arrangement of the Lisfranc joint between the midfoot and forefoot is complex and not just critical for bipedal gait but also for prevention, management, and rehabilitation of injuries in this region. MATERIAL AND METHODS: In forty adult cadaveric lower limbs, the Lisfranc mortise, the ligaments and supports were observed and noted. RESULTS: The structural arrangement that accords stability to the joint has osseous, ligamentous, and tendinous components. A bony mortise, which is deep medially, disrupts the linearity of the joint line. An extensive Lisfranc ligament with confluent interosseous and plantar parts was observed. Tibialis posterior, peroneus Longus and Lisfranc ligament exhibit a unique anatomical arrangement that supports the joint inferiorly. CONCLUSION: The study documents a unique lattice of tendons and ligament offering dynamic support to the joint. Demands of assumption of erect posture and bipedal walking in humans like adduction of the first ray of the foot, maintenance of longitudinal and transverse arches of the foot and ability stiffen midfoot for efficient forefoot take-off are well reflected in the joint structure and supports.
