“…Some studies (Goertzen et al 1992, Wada et al 1997, Georgoulis et al 2001, Adachi et al 2002 have claimed that surgery helps recovery of the proprioceptive apparatus in the ACL-reconstructed knee, from morphological findings. In line with this possibility, we did not resect the injured ACL remnants and we included reconstructions with pediculated grafts.…”

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

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.

“…The advantages of this surgical technique include the following: a) the intact remnant may protect the autograft and maintain its blood supply, providing support for the healing process in the autograft; b) sparing the intact portion of the ACL fibers may maintain some proprioceptive innervation of the ACL, thus providing faster and safer return to sports activity. [4][5][6] Earlier studies have shown that sparing the intact portion of the ACL has a positive effect on joint stability, joint position sense, and functional scores in patients that undergo surgical reconstruction of partial ACL lesions 1,[7][8][9] ; however, no study has examined the ability of this surgical technique to restore isokinetic muscle strength in patients with partial ACL lesions. As such, the present study aimed to assess isokinetic muscle strength following surgical reconstruction of partial ACL lesions.…”

Background: Surgery that spares the intact portion of the ACL seems to be more favorable. This surgical technique has a positive effect on joint stability, joint position sense and functional scores in patients with partial ACL lesions. Aim: This study aimed to assess isokinetic muscle strength following surgical reconstruction of partial ACL lesions. Materials and Methods: The study included 13 recreational athletes with partial ACL lesions that underwent surgical reconstruction. In all ACL reconstructions the remnant ACL was preserved and reinforced with hamstring autografting. The primary outcome parameter was isokinetic muscle strength of the knee muscles. The secondary outcome parameters were Single Leg Stance Test (SLST) score and the Cincinnati knee-rating score. The clinical outcomes were compared between the treated knees and non-treated (contralateral) knees. Results: There wasn't a significant difference in peak isokinetic torque of the knee flexors at 60° s -1 and 180° s -1 between the treated and non-treated knees (p>0.05); however, there was a significant difference in peak isokinetic torque of the knee extensors at 60° s -1 and 180° s

“…Although mechanoreceptors in the ACL seem to play an important role in proprioceptive function, Adachi et al found no correlation between the number of mechanoreceptors in the ACL and proprioceptive function 9) . Somatosensory information from the lower limb contributes to postural control, and reports of decreased knee proprioception have prompted researchers to study the effects of ACL injury through measuring the standing balance 13,14) .…”

“…This neural input is integrated by the CNS to generate a motor response. Sensory receptors are present in the skin, muscles, joints, ligaments and tendons [8][9][10][11] . Since a ligament injury causes a disturbance in the somatosensory system it may affect the central programs and motor response 1) .…”

Abstract.[Purpose] The aim of this study was to determine the functional level of activity and postural control after rehabilitation of anterior cruciate ligament reconstructed knees and compare them with nonoperated limbs and healthy limbs in control subjects.[Subjects] Twenty-seven patients participated in the study: 17 had undergone reconstruction with a bone-patellar tendon-bone and 10 with a semitendinosus graft technique. The same rehabilitation protocol was used for all of the patients. Besides the patients, 18 healthy volunteers participated as a control group. [Results] There were no significant differences for the eyes open static stabilometry test between operated and non-operated limbs of the patients. On the other hand, there were statistically significant differences for the closed eyes static balance test between the operated and non-operated limbs at 3 and 6 months after surgery. There were significant differences for the eyes open static balance test between the 3rd and 6th, and 6th and 12th months and for the eyes closed test of non-operated limbs between the same months as well. No statistically significant differences were noted in the dynamic balance tests between the patients and the control group. Lysholm scores of the patients obtained at 6 and 12th months after surgery were significantly better than those at 3 months after surgery. Different operation techniques revealed no significant differences in any test performed at any time.[Conclusions] Performing a postoperative sportive rehabilitation including specific proprioceptive training sessions has positive effects both on clinical status and postural control of the patients.
