“…Another interesting finding of this study is that De Lima et al 1 found ALL extensions to the anterior horn and body of the lateral meniscus. The lateral meniscus is more mobile than the medial meniscus, and therefore a control mechanism is needed to prevent lateral meniscus from impinging between the tibia and the femur.…”

“…The ALL tightens with internal rotation, and the mean length increases from 3.6 mm at 30 to 9.9 mm at 90 of flexion. 12 It did not surprise me that De Lima et al 1 found Ruffini endings in the ALL. It is possible that internal rotation tightened the ALL and Ruffini endings activate to limit the rotation and translation.…”

“…Type 1, Ruffini endings, and type 4, free nerve endings, were found in ALL, and the sensorimotor role of ALL was proved. 1 The sensorimotor system of the knee is important but did not receive much attention until Schultz et al 2 first described the mechanoreceptors in the human anterior cruciate ligament (ACL). In the past 5 decades, anatomic studies have mainly focused on origin and insertion points of ligaments and tendons around the knee, yet study of the close relation with sensorimotor system is relatively new.…”

“…Mechanoreceptors are the first step in this pathway. Mechanoreceptors were previously observed in many different joints from the thumb to lumbar discs, 5,6 yet De Lima et al 1 are the first researchers to evaluate the ALL for mechanoreceptors.…”

“…The second difficulty is the sectioning technique: although mechanoreceptors are frequently located near bony insertions, they could lie through the entire ligament, and, thus, the whole ligament has to be analyzed, which could alter the analysis. De Lima et al 1 used confocal microscopy with the immunofluorescence method. This is a good way to analyze mechanoreceptors because it can help determine both quantitative values and morphology of mechanoreceptors.…”

Purpose A histological study of a structure between the posterior horn of the lateral meniscus and the anterior cruciate ligament. Methods Bilateral fresh-frozen cadaveric knees of two male donors (age 71 and 76 years) with no history of prior knee injury were examined. All dissections were performed by one experienced orthopaedic surgeon. Haematoxylin and Eosin staining was used to reveal tissue morphology. Goldner trichrome staining was used to evaluate the connective tissue. S100 and PGP 9.5 labelling were used for immunohistochemical analysis. Results In all cadaveric knees, a structure between the posterior horn of the lateral meniscus and the anterior cruciate ligament was identiied. Histological analysis conirmed the ligamentous nature of this structure. Furthermore, Golgi tendon organs were observed within the ligamentous structure. Conclusion This is the irst study showing the presence of mechanoreceptors within the ligamentous structure between the posterior horn of the lateral meniscus and the anterior cruciate ligament. The ligamentous structure could contribute to stability of the knee by providing proprioceptive input, while preservation of the ligamentous structure might ensure a better functional outcome after surgery.
