Abstract
Background/Aim: Proprioception recovery is one of the main postoperative rehabilitation goals after the anterior cruciate ligament (ACL) reconstruction. The aim of this study was to examine the level of proprioception recovery in patients 9 months after the ACL reconstruction using hamstring graft. Methods: A prospective study followed 70 male subjects (mean age 27.36 ± 5.94) divided into two groups depending on the type of proprioceptive exercise applied. Group A patients (n = 35) underwent proprioceptive training on a Biodex 4 Pro System isokinetic dynamometer for 10 minutes 5 times per week. In group B, patients underwent proprioception exercises in the gym for 10 minutes 5 times per week. The degree of recovery of proprioception was measured on an isokinetic dynamometer preoperatively and 9 months after ACL reconstruction. Flexion angles in the operated knee of 15, 30 and 45 degrees were monitored. The Chi-square test was used for statistical analyses. The value of p < 0.05 was considered significant. Results: A significant difference was found in the recovery of proprioception in patients depending on the type of training applied. Statistically significant recovery of proprioception was observed in patients from both groups 9 months after ACL reconstruction, but it was better in patients of group A (p < 0.05). Conclusion: Applying proprioceptive training on an isokinetic dynamometer achieves better proprioceptive recovery in patients 9 months after ACL reconstruction versus dynamic exercises in the gym.
Highlights
Proprioception is one of the key elements in the complex process of maintaining balance.[1]
The degree of proprioception recovery was investigated in patients 9 months after anterior cruciate ligament (ACL) reconstruction with a hamstring graft using two types of therapeutic exercises, isokinetic and dynamic. This prospective clinical study comprised a total of 70 recreational athletes, men, divided into two groups depending on the type of proprioceptive exercise applied during rehabilitation after arthroscopic ACL reconstruction with a hamstring graft
It can be expected that the rupture of the ACL will lead to the rupture of the reflex arc because the rupture had eliminated the first element of the reflex arc, the receptor.[11] the recovery of proprioception in patients after ACL reconstruction.[12,13,14,15,16,17,18]
Summary
Proprioception is one of the key elements in the complex process of maintaining balance.[1] Having in mind the histological structure of the anterior cruciate ligament (ACL), it is clear that its rupture leads to damage of fast and slow mechanoreceptors and to damage of proprioception.[2] Surgical treatment of patients after the anterior cruciate ligament reconstruction restores static stability, but achieving dynamic stability is the task of postoperative rehabilitation. If the restoration of proprioception is not achieved, the patient is at risk of re-injuries to the structures of the operated and injuries of the contralateral knee.[3] During the postoperative rehabilitation of patients after ACL reconstruction proprioceptive re-education exercises are one of the constituent elements of the rehabilitation protocol.
