Histological analysis of the joint continuous capsule. a The bone model of the right medial ankle shows the locations of the anterior section (b, c) and anteromedial section (d, e). b and d show the macroscopic views of (c) and (e), which were stained with Masson’s trichrome, respectively. b, c At the anterior part of the ankle, the fatty tissue of the continuous capsule (asterisk) covered the ankle and talonavicular joints. d, e At the anteromedial part of the medial ankle, the fibrous tissue (black circle) connected between the medial malleolus and the medial talus. The fatty tissue (asterisk) occupied the space between the fibrous and the cartilaginous tissues. The cartilaginous tissue (dagger) covered the talus and connected the medial malleolus and the medial navicular. Prox, proximal; Dist, distal; Nav, navicular; MM, medial malleolus; scale bar, 5 mm
