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.
