Anterior cruciate ligament injuries treated with quadriceps tendon autograft versus hamstring autograft: A randomized controlled trial.

BACKGROUND

One of the most common grafts used to repair anterior cruciate ligament (ACL) rupture is the hamstring tendon (HT) autograft. However, another proposed option to repair the ACL is the quadriceps tendon (QT) autograft. This study aimed to compare the pain and clinical results between patients with ACL injury treated with QT autograft and with HT autograft.

MATERIALS AND METHODS

The Ethics and Investigation Committee of our institution approved the study. The patients were randomized into two groups: one group was treated with QT autograft and the other group was treated with HT autograft. The patients were evaluated preoperatively and postoperatively using the Lysholm-Tegner score, International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, and visual analog scale (VAS), at 2 weeks and 1, 3, 6, and 12 months.

RESULTS

A total of 28 patients with a primary ACL injury were included in the study. No significant differences in VAS pain, Lysholm knee and Tegner activity scale scores, and IKDC score between the HT and QT groups were observed at any time point. All patients had favorable outcomes and significantly improved evaluation scores.

CONCLUSION

The patients treated with QT autograft had clinical results and post-operative pain similar to those of patients treated with HT autograft for ACL reconstruction.
