Novel modified implant fixation technique for arthroscopic anterior cruciate ligament reconstruction using hamstring and peroneus longus autografts in limited resource settings: a comparative study on knee stability

BACKGROUND: With the increasing popularity of contact sports, the incidence of anterior cruciate ligament (ACL) injuries is rising. ACL reconstruction has been recognized as the most common procedure to restore knee stability. One of the main drawbacks of standard implant is that the medical costs incurred are often beyond the reach of most patients, so patients who need ACL reconstruction surgery must find other financially affordable alternatives. Due to the many knee joint complications involving patellar and hamstring tendon grafts in ACL reconstruction, the new proposed solution is anterior cruciate ligament reconstruction using the peroneus longus tendon.METHODS: This research was an analytical study with a cross-sectional observational design. The sample in this study compared patients diagnosed with ACL rupture who received ACL reconstruction treatment using a modified implant with a hamstring tendon autograft and a peroneus longus tendon autograft. The sample was examined using the consecutive sampling technique by tracing medical record data, used as secondary data, and through the distribution of the Lysholm Knee and the International Knee Documentation Committee (IKDC) scoring questionnaires.RESULTS: Out of 69 samples that met the inclusion criteria, 45 were hamstring autograft samples, and 24 were peroneus autograft samples. There was no significant difference between the two groups in terms of Lysholm Knee Score (P=0.135), International Knee Documentation Committee Score (P=0.352), use of a mobile aider (P=0.488), power grading (P=0.905), and range of motion of the knee (P=0.110).CONCLUSIONS: The hamstring autograft and peroneus autograft groups did not show a significant difference in clinical functional outcomes after ACL reconstruction with the modified implant technique.
