Outcome of Primary Anterior Cruciate Ligament Reconstruction with Peroneus Longus and Bone-Patellar Tendon-Bone Autografts: A Clinical Comparative Study

Background: The aim of this study is to compare the mid-term outcomes of primary tear of the anterior cruciate ligament (ACL) reconstruction via the use of peroneus longus tendon (PLT) and bone-patellar tendon-bone (BPTB) autografts. Methods: 53 patients (group 1) received ACL reconstruction via BPTB, whereas 55 patients (group 2) received arthroscopic ACL reconstruction using PLT autograft. Results: In group 1, the mean preoperative and postoperative scores on the Lysholm Knee Questionnaire (LKQ) scale resulted in 69.2 +/- 10.7 points and -92.2 +/- 6.4 points, respectively. The average preoperative and postoperative value on the International Knee Documentation Committee (IKDC) scale was 68.2 +/- 10.6% and -90.1 +/- 9.5%, respectively. For KT-1000, according to the results of surgical treatment, it is -3.7 +/- 1.4 mm, and for the American Orthopaedic Foot & Ankle Society (AOSAF) it is -95.3 +/- 4.5%. The autograft ruptured within 2 years after operation in 4 of 50 patients. In group 2, the mean score on the LKQ scale before the operation was 70.2 +/- 11.6 points, after -94.3 +/- 0.5 points. The average value on the IKDC scale before surgery was 68.6 +/- 8.7%, after -91.5 +/- 8.2%. KT-1000 -3.4 +/- 1.2 mm. Conclusion: The results in both groups can be assessed as good; peroneus longus muscle tendon autograft is an alternative graft for the primary reconstruction of ACL, preserving the dynamic stabilizers of the knee and has no effect on the formation of flat feet and other disease in the postoperative period.
