[Mechanoreceptors in the distal aspects of the m. vastus medialis?].
Five cadavers were fixed in Jores' solution and alcohol. The distal parts of the medial vastus muscle and the medial parts of the patella ligament and of the capsule of the knee joint were prepared and histologically examined. Previous examinations had shown mechanoreceptors in the knee joint ligaments; the present study was designed to find whether mechanoreceptors could be identified in the anatomical structures mentioned, in which case an arthrotomy by the Payr access would interrupt the muscle reflexes. Only some mechanoreceptors in the medioventral parts of the knee joint capsule close to the tendon of the great muscle could be identified. Thus, when the Payr access is used there is no interruption of the sensibility transmitted by proprioceptors.
