How many articular facets are present in the 1st MTP joint capsule?

Explanation:
The first MTP joint is not a simple hinge; its capsule contains six separate articular surfaces due to the two plantar sesamoid bones that lie within it. There are two facets where the metatarsal head articulates with the base of the proximal phalanx (medial and lateral). There are then two plantar facets on the metatarsal head that engage the medial and lateral sesamoids, and two corresponding plantar facets on the base of the proximal phalanx that engage the sesamoids. Together, these form six distinct articular facets within the joint capsule.
