Abstract:
Objective:To compare the efficacy of internal brace-augmeted reconstruction combined with tape tail-folding anterolateral ligament reconstruction (ALL) and isolated internal brace-augmented reconstruction for high-grade pivot-shift anterior cruciate ligament (ACL) injuries.Methods:A retrospective cohort study was conducted to analyze the clinical data of 60 patients with high-grade pivot-shift ACL injuries who were admitted to 910th Hospital of Joint Logistics Support Force of PLA between March 2021 and March 2023, including 48 males and 12 females, aged 18-40 years [(28.4±5.6)years]. All ACL injuries were at grade III. The pivot-shift test results were classified as grade 2 in 42 patients and grade 3 in 18. According to the surgical technique, 30 patients underwent artificial internal brace-augmented ACL reconstruction combined with tape tail-folding ALL reconstruction (joint ACL reconstruction group), while the other 30 received isolated internal brace-augmented ACL reconstruction (simple ACL reconstruction group). The two groups were compared in terms of operative duration, intraoperative blood loss, improvement rate of pivot-shift at 3 months postoperatively, rate of sports function recovery at the last follow-up, Tegner and Lysholm scores preoperatively, at 3 months postoperatively, and at the last follow-up, and incidence of postoperative complications.Results:All the patients were followed up for 6-24 months [(14.8±5.8)months]. The operative duration and intraoperative blood loss were (44.6±8.2)minutes and (45.3±4.6)ml in the simple ACL reconstruction group, significantly shorter or less than (58.0±7.4)minutes and (61.8±9.1)ml in the joint ACL reconstruction group ( P<0.01). At 3 months after surgery, the improvement of pivot-shift test was 93%(28/30) in the joint ACL reconstruction group, higher than 73%(22/30) in the simple ACL reconstruction group ( P<0.05). At the last follow-up, the recovery rate of motor function was 100%(30/30) in the joint ACL reconstruction group, significantly higher than 80%(24/30) in the simple ACL reconstruction group ( P<0.05). There were no statistically significant differences in Tegner or Lysholm scores between the two groups before surgery ( P>0.05). At 3 months after surgery and at the last follow-up, the Tegner scores were (3.8±0.5)points and (5.7±1.1)points in the joint ACL reconstruction group, significantly higher than (2.5±0.6)points and (3.9±0.9)points in the simple ACL reconstruction group ( P<0.01). At 3 months after surgery and at the last follow-up, the Lysholm scores were (67.2±5.7)points and (89.4±6.4)points in the joint ACL reconstruction group, significantly higher than (56.4±5.0)points and (72.6±5.7)points in the simple ACL reconstruction group ( P<0.01). Both groups demonstrated gradual improvement in Tegner and Lysholm scores at all postoperative time points, compared to preoperative values ( P<0.05). After operation, one patient in the joint ACL reconstruction group had superficial tibial infection, with a complication rate of 3% (1/30), whereas there was one patient with superficial tibial infection, and one with ligament injury in the simple ACL reconstruction group, with a total complication rate of 7% (2/30)( P<0.05). Conclusion:For high-grade pivot-shift ACL injuries, internal brace-augmented reconstruction combined with tape tail-folding ALL reconstruction can significantly improve knee rotational stability, promote motor function recovery, and enhance knee joint outcomes, compared to isolated internal brace-augmented reconstruction.
