Abstract
Background: Mechanoreceptors are subtypes of somatosensory receptors. It conveys not only kinetic stimuli but also pressure, stretching, touch, and even a sound wave. Few studies have determined whether mechanoreceptors are present in the bone–patellar tendon–bone (BPTB) autograft used during anterior cruciate ligament reconstruction (ACLR). This study aimed to investigate whether mechanoreceptors are present in auto BPTB after ACLR.
Methods: Tissue samples were obtained from four participants who had undergone reruptured BPTB autograft during ACLR revision. In the control group, four biopsy specimens of the normal patellar tendon were obtained from patients who had undergone total knee arthroplasty. To check the presence of mechanoreceptors, H&E staining was performed. Immunohistochemical studies were also performed on all biopsy specimens to identify neuronal and neurolytic markers using monoclonal antibodies against glial fibrillary acidic protein, neuron-specific enolase, neurofilament, and S-100 protein.
Results: H&E staining did not reveal any mechanoreceptors in the ruptured auto BPTB ACLR group. No neural tissue analogs, confirmed to be mechanoreceptors with monoclonal antibodies by the ultraview DAB detection kit, were found in all specimens obtained from the ruptured auto BPTB ACLR group. However, mechanoreceptors were found in the control group by H&E and immunohistochemical staining.
Conclusion: In this study, BPTB autografts did not have any mechanoreceptors. Thus, no mechanoreceptors are preserved in the ACLR despite using the BPTB autograft. This study supports the advantage of the remnant-preserving techniques for ACLR.
