Balance Ability and Proprioception after Single-Bundle, Single-Bundle Augmentation, and Double-Bundle ACL Reconstruction

Abstract

Purpose. The present study sought to determine the influences of single-bundle (SB), single-bundle augmentation (SBA), and double-bundle (DB) reconstructions on balance ability and proprioceptive function. Methods. 67 patients who underwent a single- or double-bundle ACL reconstruction or a SBA using multistranded autologous hamstring tendons were included in this study with a 1-year follow-up. Body sway and knee kinesthesia (using the threshold to detect passive motion test (TTDPM)) were measured to indicate balance ability and proprioceptive function, respectively. Additionally, within-subject differences in anterior-posterior stability of the tibia and lower extremity muscle strength were evaluated before and after surgery. Results. At 6 and 12 months after surgery, DB reconstruction resulted in better balance and proprioceptive function than SB reconstruction (P < 0.05). Although no significant difference was observed in balance ability or proprioceptive function between the SBA and DB reconstructions, knee stability was significantly better with SBA and DB reconstructions than SB reconstruction (P < 0.05). No significant differences were found in quadriceps and hamstrings strength among the three reconstruction techniques. Conclusions. Our findings consider that joint stability, proprioceptive function, and balance ability were superior with SBA and DB reconstructions compared to SB reconstruction at 6 and 12 months after surgery.

Mechanism of Activating the Proprioceptive NT-3/TrkC Signalling Pathway by Reverse Intervention for the Anterior Cruciate Ligament–Hamstring Reflex Arc with Electroacupuncture

“…Proprioception of the ACL is closely related to knee joint stability, which is realised through feedback regulation of the central nervous system; however, the key node on the pathway remains unknown [ 27 – 30 ]. Many studies confirmed that when the ACL proprioception function is decreased, the neural feedback regulation pathway is bound to be disordered; therefore, it could have further impact on the proprioception function [ 31 , 32 ]. Some studies showed that NT-3 was the key induced signal of proprioceptive transduction; when NT-3 expression was normal, the proprioceptive nerve fibres could control the target organs and have physiological roles [ 33 – 35 ].…”

Postoperative Evaluation after Anterior Cruciate Ligament Reconstruction: Measurements and Abnormalities on Radiographic and CT Imaging

“…2) (9). A single-bundle reconstruction is performed by producing one single femoral tunnel and one single tibial tunnel, with focus on reproducing the AM bundle.…”

“…A single-bundle reconstruction is performed by producing one single femoral tunnel and one single tibial tunnel, with focus on reproducing the AM bundle. The selective single-bundle augmentation reconstruction is focused on AM or PL bundle repair with preservation of the remaining intact bundle, while the double-bundle reconstruction uses two separate grafts to replace the positioning of both the AM and PL bundles (9). An anatomic double-bundle, four-tunnel reconstruction using the double-bundle technique has the potential to restore the biomechanics of the knee better than the classic single-bundle, two-tunnel technique (Fig.…”

Effects of extremity positioning on radiographic evaluation of femoral tunnel location with digitally reconstructed femoral lateral radiographs after anterior cruciate ligament reconstruction

“…Although anterior cruciate ligament (ACL) reconstructions are routinely performed to treat ACL injuries, these injuries may have serious consequences [ 1 ]. Double-bundle, single-bundle (SB) augmentation and SB techniques are widely practiced to reconstruct the ACL [ 2 ]. The double-bundle and SB augmentation techniques are also referred to as anatomic double-bundle and anatomic SB techniques respectively.…”
