Abstract:

Background

The balance disorder with the anterior cruciate ligament (ACL) injury is associated with not only mechanical instability but also proprioceptive dysfunction. Although the ACL reconstruction by single bundle augmentation (SBA) and double bundle (DB) could restore more normal knee kinematics than that by single bundle (SB), the different among the three surgical methods on balance ability and proprioception is still unclear.

Purpose

The purpose of the present study was to reveal that the influences of the SB, SBA, and DB reconstructions on balance ability and proprioceptive function
Study design: Descriptive Laboratory Study.

Methods

Sixty-seven patients who underwent single- or double ACL reconstruction or single bundle augmentation using multistranded autologous hamstring tendons were included in this study after 1-year follow up. Body sway and kinesthesia of knee were measured to indicate balance ability and proprioceptive function, respectively. Additionally, side-to-side difference of anterior-posterior stability of the tibia and lower extremity muscle strength were evaluated before and after the surgery. Results: The balance ability and proprioceptive function in the DB reconstruction were significantly better than that in the SB reconstruction at 6 and 12 months after the surgery. For the balance ability and proprioceptive function, no significant differences were found between the SBA and DB reconstructions at 6 and 12 months after the surgery. The knee stability in the SBA and DB reconstruction were significantly better than that in the SB reconstruction at 6 and 12 months after the surgery. For the muscle strength, no significant differences were found among three reconstructions at 6 and 12 months after the surgery.

Conclusions

Although the lower extremity muscle strength was almost same among three reconstructions, joint stability, proprioceptive function, and balance ability were superior in the SBA and DB reconstructions than these in the SB reconstruction at 6 and 12 months after the surgery
