“…They are surrounded by a capsule consisting of 1-5 cell-layers. A myelinated nerve 5-7 pm of diameter, enters the corpuscle at the pole losing the myelin on its course; it then splits into different dentrites [12][13][14][15][16]21,29,39,42]. All corpuscles observed by us correspond with this structure.…”

The neural histology of the anterior band of the inferior glenohumeral ligament (IGHL) was studied in 11 fresh shoulder specimen using a special silver impregnation technique. Between the collagen fibers small myelinated and unmyelinated dendrites could be detected. The appearance of neurovascular structures in the adjacent synovial layer clearly exceeded the typical supply to soft tissues. Analysing about 11,000 sections Ruffini mechanoreceptors that are known to be slow adapting were found on the humeral insertion of the band. The sections containing these neural end organs were identified by means of transillumination and reflection-contrast microscopy and reconstructed using three-dimensional image processing. The presence of neural structures including Ruffini corpuscles in these most important passive stabilizers of the shoulder joint shows that these ligaments function also as an active safety device. There slow adaption is a prerequisite for muscular reflexes counteracting the tensile stresses to which the passive stabilizing structures of the shoulder are exposed. A disruption of the continuity of these structures by mechanical forces or surgery can reduce the biofeedback and proprioceptive quality and thus lead to a decrease of shoulder function andlor stability. These observations should be taken into account when planning surgical interventions involving the IGHL. Procedures like capsule shifts or plications may affect mechanoreceptor orientation and concentrations, thereby affecting the interaction between these structures and the synergistic muscles. When possible, these intervention should avoid receptor-dense regions while attempting to restore normal anatomical orientation and tissue tension.

“…In 1991, Katonis et al 4 in their histological study on cadaver human knees described two types of encapsulated mechanoreceptors. They were located at the femoral and tibial attachments and on the surface of the ligament.…”

“…They show nerve endings to be present in anterior cruciate ligament and PCL preparations, while also observing a reduction in the number of mechanoreceptors in degenerative diseases of the knee. The presence of proprioceptors in the PCL has been demonstrated by a number of authors using various staining methods [9,13]. Barrett et al [4] and Skinner et al [19] describe a weakening of proprioception to be associated with age and with greater degenerative disease.…”
