Comparative Clinical Efficacy Analysis Of Early Knee Function After Anterior Cruciate Ligament Reconstruction By Using Peroneus Longus Tendon And Hamstring Tendon

Objectives: We reconstructed the anterior cruciate ligament(ACL)using Peroneus Longus Tendon and Hamstring Tendon,respectively.The knee function scores of the two groups were followed up and compared after the graft surgery.Methods: In this study,patients with ACL injury from October 2019 to March 2021 in our hospital were studied.A total of 53 patients were included,invilving 21 patients assigned to peroneus longus tendon group(Group A)and32 patients assigned to the Hamstring Tendon group(Group B).All patients in the two groups were performed ACL reconstruction by the same surgeon.All study individuals received the same rehabilitation training mode after surgery.Follow-up periods were performed at 3 months,6 months and 12 months postoperation.Knee function scores were evaluated by the Lachman test,Lysholm score,IKDC score and ankle score.Results: Clinical characteristics were not significant different(P value > 0.05)between the two groups,including the age,gender,cause of injury,length of hospitalization,and the time length from ACL injury to surgery.Operation time between the two groups were significantly different(P value < 0.05).The knee function scores in the two groups before and after operation were as followed: Lachman test scores: all patients were tested positive before surgery,while the number of positive cases in Group A at 3 months,6 months and 12 months post operation were 4 cases,4cases and 3 cases respectively.The number of positive cases in Group B at 3months,6 months and 12 months post operation were 5 cases,4 cases and 3cases respectively.there are no significant differences concerning the Lachman test scires between the two groups(P value > 0.05).Lysholm scores: Group A:preoperation(45.86 ± 2.71),3 months postoperation(78.48 ± 2.28),6 months postoperation(83.33 ± 2.78),12 months postoperation(89.43 ± 2.06).Group B:preoperation(44.56 ± 2.63),3 months postoperation(72.53 ± 3.19),6 months postoperation(79.59 ± 2.23),12 months postoperation(88.53 ± 2.54).IKDC scores: Group A: preoperation(50.10 ± 4.69),3 months postoperation(80.81 ±2.11),6 months postoperation(85.24 ± 1.51),12 months postoperation(90.43 ±3.07);Group B: preoperation(49.59 ± 4.82),3 months postoperation(75.25 ±2.54),6 months postoperation(79.97 ± 1.75),12 months postoperation(89.47 ±3.02).The scores were significantly improved over time postoperativon in both groups.and the comparative results of the two groups showed that the Lysholm score and IKDC score were not statistically significant in the two groups of patients before and 12 months postoperative(P value > 0.05),and statistically significant(P value < 0.05)for Lysholm scores and IKDC scores at 3 and 6months postoperatively.Conclusion: In this study,we found that the knee function scores in 3 and 6 months after ACL reconstruction were better in patients using Peroneus Longus Tendon than patients using Hamstring Tendon,while there are no significant differences between the two groups post 1 year ACL reconstruction.Overall,peroneus longus tendon reconstruction may be superior to the hamstring tendon in clinical efficacy.
