ABSTRACT
PURPOSE:
To evaluate the safety of anterior cruciate ligament reconstruction (ACLR) with suture augmentation (SA) through clinical evaluations, monitoring of complications, and evaluation of early graft remodeling using magnetic resonance imaging (MRI).METHODS:
Data of participants who underwent anatomic double-bundle ACLR using hamstring tendon autografts, with a minimum 2-year follow-up, were retrospectively reviewed. Participants undergoing ACLR with SA were propensity-matched with those without SA. Postoperative clinical evaluations, including Lysholm and Tegner activity scores, International Knee Documentation Committee (IKDC) evaluation scores, KT-1000 side-to-side difference for knee stability at a 2-year follow-up, and complications, were recorded. The minimal clinically important difference (MCID) was calculated for IKDC scores. The anteromedial bundle graft was categorized into distal, middle, and proximal regions on the 6-month and 1-year postoperative MRI. The signal-to-noise quotient (SNQ) of each region of interest was calculated to evaluate the graft signal intensity, which was compared between the two groups using Welch's t-test.RESULTS:
Fifty-three participants were included in each group. No significant differences were observed between the non-SA and SA groups in the Lysholm scores (96.6 ± 6.2; 95.3 ± 5.8, P = 0.25), Tegner activity scores (4.8 ± 1.4; 5.0 ± 1.3, P = 0.49), IKDC scores (90.4 ± 10.8; 87.1 ± 12.9, P = 0.15), percentage of patients meeting the MCID (94.3%; 83.0%, P = 0.12), or postoperative KT-1000 side-to-side difference (0.9 ±1.2; 0.7 ± 1.8 mm, P = 0.56). One (1.8%) and two (3.7%) cases of re-tears occurred in the non-SA and SA groups, respectively; no other complications occurred. The postoperative SNQ measurements revealed no significant differences in signal changes in all regions of the grafts between the two groups.CONCLUSIONS:
This study confirmed no difference in graft signal intensity on MRI or clinical outcome between ACLR with and without SA at the 2-year follow-up. LEVEL OF EVIDENCE Level III, retrospective, comparative study.
