Abstract
PURPOSE: To investigate the functional characteristics of Bassett's ligament in the ankle, focusing on mechanoreceptors and potential problems following resection of Bassett's ligament. METHODS: Bassett's ligament, the anterior talofibular ligament (ATFL), and synovium were obtained from 20 ankles of 10 fresh-frozen cadavers. Histologically, mechanoreceptors were identified and classified as Ruffini (type I), Vater-Pacini (type II), Golgi-Mazzoni (type III) corpuscles, and free nerve endings (type IV). Differences in receptor densities were compared. RESULTS: Type I clusters were observed with three to six ramifications; type II mechanoreceptors were encapsulated in clusters of two to four with ovoid or cylindrical shape; type III were amorphous, long and wide, and fusiform- or spindle-shaped; and type IV were long and fine without a defined shape. Differences in the densities of the mechanoreceptors inside three soft tissues (Bassett's ligament, ATFL, and synovium) were not significant. CONCLUSION: There were no significant differences in the densities of the four types of mechanoreceptors among the soft tissues studied. In Bassett's ligament, type I mechanoreceptors were present at significantly higher densities than the other receptors.
