Eva Ageberg, RP7; MS$ Markus W a l d h , M9 Rose Zatferstrom, RP7; P h D Several tests of human conscious knee proprioception have been described, but there is no consensus or reference standard established. Difficulties remain in the separation of information originating from muscles, tendons, and joints, and the tests cannot discriminate between loss of afferent signals or altered activity in the remaining receptors. There is convincing evidence from several descriptive studies that the afferent information is altered after a knee ligament injury and severely disturbed in some patients with anterior cruciate ligament (ACL) injuries. However, an inherent inferior proprioceptive ability may also exist in some individuals, which makes them vulnerable to injuries. The deficits in proprioception have mostly been studied and related to the consciously registered sense, whereas the extent of possible disturbances of the unconscious or reflectory mechanisms is largely unknown. The latter may, at least from a theoretical point of view, be predominantly contributing to the overall afferent regulation, and a possibility for major defects thus exists, since there is no knowledge of the quantified relation between the conscious and unconscious part. The clinical importance of the altered afferent information has not been evaluated properly, and the role of proprioception that contributes to function has yet to be investigated. A higher physiological sensitivity to detecting a passive joint motion closer to full extension has been found both experimentally and clinically, which may protect the joint due to the close proximity to the limit of joint motion. Proprioception has been found to have a relation to subjective knee function, and patients with symptomatic ACL deficiency seem to have larger deficits than asymptomatic individuals. Little is known about whether training can restore defects in sensory information or by which mechanisms possible compensatory pathways are established. In rehabilitation, each patient must, however, create muscle strength, alertness, and stiffness in harmony with the disturbed mechanics of the knee, which are present both after nonoperative treatment of the ACL and after a reconstruction of the ACL. ) Orthop Sports Phys Ther 2001;3 1:567-576.

“…Neuromuscular control system sensors, called mechanoreceptors (4) , found in joints, skin and muscles, inform the CNS about changes in position, motion perception and joint tension (5) . Missed information by the anterior cruciate ligament (ACL) mechanoreceptors can be compensated by information coming from other knee structures, through a specific training (6) . Proprioceptive neurophysiologic function of the ACL has been considered as important as its biomechanical role in maintaining joint stability (7).…”

“…Changes in neural function and muscle physiology have been suggested (Williams et al 2004), and according to clinical studies, a proprioceptive deficit remains after ACL reconstruction (Bonfim et al 2003). The fact that there may be persistent neurophysiological abnormalities after ACL reconstruction even suggests that the loss of ACL mechanoreceptors may initiate central nervous system modifications that are not compensated for by other nervous structures (Valeriani et al 1999).…”

Insufficient recovery of neuromuscular activity around the knee after experimental anterior cruciate ligament reconstruction

et al. 2008

Background Operative and nonoperative treatment of anterior cruciate ligament (ACL) injuries is often associated with a lack of proprioception and persistent muscle weakness of unknown origin.Methods This long-term study in the cat experimentally compares both neural and muscular activity in the articular nerves of the knee (PAN and MAN), quadriceps and hamstrings, in the chronic unstable knee, and in the reconstructed knee. We also investigated changes in neuromuscular response due to the mechanical competence of the graft, comparing stable and unstable reconstructed knees.Results We found increased periarticular muscle activity during anterior tibial translation in chronically unstable knees. Both reconstructed and non-reconstructed knees lost fast reactive activity in the articular nerves. When stability was recovered after reconstruction, the knees showed a more adjusted-although incomplete-muscular reaction.Interpretation ACL-injured knees in the cat, with or without reconstruction, show definite abnormalities in neuromuscular reaction in the long term. Regaining stability with a competent graft in the reconstructed knee is crucial for reduction of this anomalous reaction.

Clinical and neurophysiological abnormalities before and after reconstruction of the anterior cruciate ligament of the knee

Abstract: We suggest that the loss of the knee mechanoreceptors can be followed by modifications of the central nervous system, which are not compensated by other nervous structures.
