Comparative Study of the Reconstruction of Anterior Cruciate Ligament with Peroneal Longus Tendon and Hamstring Tendon Based on Magnetic Resonance Imaging

Objective: To compare the effect of reconstruction of anterior cruciate ligament (ACL) with peroneal longus tendon (PLT) and hamstring tendon (HT) using magnetic resonance image (MRI). Methods: Fifty-six patients with ACL rupture were treated with ACL reconstruction. Among them, 28 patients were treated with PLT reconstruction (treatment group) and 28 patients were treated with HT reconstruction (control group). There were no significant differences in gender, age, injury side, course of disease, preoperative Lachman test, Lysholm score, IKDC score, joint mobility, MRI image between the two groups (P > 0.05). Result: The incision healed in the first stage after operation in both groups, and there were no significant neurovascular injuries and knee synovitis complications. Comparing the MRI of the two groups after operation, the effect of the treatment group was better than that of the control group. There were no complications in both groups. The Lysholm score and IKDC score of the treatment group were better than those of the control group at 6 and 12 months after operation (P > 0.05). There was no significant difference in Lachman test between the two groups at 6 and 12 months after operation (P > 0.05). At 3 and 12 months after operation, the joint activity of the treatment group was better than that of the control group, with no significant difference (P > 0.05). The degree of tibial anterior displacement decreased significantly in both groups before and after operation (P < 0.05), but there was no significant difference between the two groups (P > 0.05). Discussion: MRI scanning technology can significantly expand the scope of human body examination, improve the detection rate and diagnostic accuracy of lesions. In traditional surgery, HT is often used as reconstruction material. However, there are many factors to be considered in the formulation of operation plan for double cruciate ligament injury, such as limb blood supply, accompanied by a variety of structural injuries, so the requirement for reconstruction is high. There was no significant difference in the recovery of knee stability between the two groups, but in terms of early recovery of knee function and subjective satisfaction of patients, the reconstruction of PLT was superior to that of HT. Conclusion: Magnetic resonance imaging can effectively diagnose the curative effect, and it is worth popularizing and applying widely. Compared with HT, ACL reconstruction with PLT is easier to operate, and the early recovery of knee joint function and it is worth popularizing and applying widely.
