AN EVALUATION OF THE CLINIC RADIOLOGICAL EFFECTS OF SINGLE-VERSUS DOUBLE-BUNDLE ARTHROSCOPIC ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION.
Keywords:Reconstruction, Anterior cruciate ligament, Lysholm scale, magnetic resonance imaging
The most common reconstructive procedure for the knee is anterior cruciate ligament (ACL) reconstruction. This research aimed to compare the clinical and radiological outcomes of arthroscopic ACL replacements using single- and double-bundles.
80 patients with isolated ACL injuries had surgery between July 2020 and July 2021, with groups for the single bundle (SB) and double-bundle (DB) reconstructions each consisting of 40 individuals. The GNRB arthrometer, the International Knee Documentation Committee, and the Lysholm scale were used to evaluate the results. The lateral pivot-shift test was used to evaluate rotational stability. To compare the repaired ACL graft orientation, postoperative magnetic resonance imaging (MRI) was done. Using a paired t-test, preoperative values, and values were compared and P <0.04 was significant.
The average follow-up was 18.2 months for the DB group and 14.8 months for the SB group. The mean Lysholm score was 94.12±2.66 in the SB group and 93.12±3.30 in the DB group at the time of the final follow-up (P value = 0.201, statistically insignificant). All of the patients, in both groups, were in grade A or B. The mean differential anterior tibial translation in the SB group was 1.44 ± 0.5 mm and in the DB group, it was 1.16 ± 0.7 mm (P = 0.104, NS). In the DB group, all of the pivot shift tests were negative, whereas, in the SB group, three patients showed positive results. According to an MRI of surgically repaired knees, both groups' mean sagittal and mean coronal ACL graft-tibial angles were equivalent (P value > 0.04, NS).
At an average of 15 months of follow-up, there was no statistically significant difference between the single-bundle and double-bundle ACL repair groups in terms of knee stability, knee ratings, subjective assessments, or MRI examination of graft inclination angles.
