Objectives:
This study aimed to compare the clinical outcomes of trans-tibial pullout repair of the medial meniscus posterior root using the lateral tibial tunnel versus the conventional medial tibial tunnel.
Methods:
In this prospective cohort study, patients with posterior root tears of the medial meniscus who underwent surgical repair were divided into two groups based on the tibial tunnel used for fixation: the medial tunnel technique (Group 1) and the lateral tunnel technique (Group 2). The Lysholm score was recorded preoperatively and 12 months postoperatively to assess knee function and the return to daily and sports activities. Demographic data, including age, gender, and associated injuries, were also documented. Statistical analysis was performed using the one-sample t-test, independent t-test, and Pearson correlation.
Results:
The mean Lysholm score in the medial tunnel group was 92.67 ± 9.28, while in the lateral tunnel group, it was 88.02 ± 13.59. Statistical analysis revealed no significant difference in the Lysholm scores between the two groups (p > 0.05), indicating comparable clinical outcomes for both techniques.
Conclusion:
Both medial and lateral tibial tunnel techniques for trans-tibial pullout repair of the medial meniscus root yield comparable functional outcomes. The choice of tunnel may be guided by anatomical considerations or surgeon preference, as no significant difference was observed in postoperative recovery, as measured by the Lysholm score.
