Abstract This study was undertaken to compare the clinical outcomes between the transosseous pull-out repair and partial meniscectomy of the medial meniscus posterior root tear (MMPRT) based on the short-term follow up, and to analyze the MRI diagnostic signs of MMPRT. Patients with MMPRTs had been randomly divided into repair group and meniscectomy group, and prospectively followed up for 12 months, the clinical results were compared using Knee injury and Osteoarthritis outcome score (KOOS) and patients’ satisfaction was evaluated by average score. Also, the MRI diagnostic signs were documented among all patients involved in the study. Final inclusions were 30 patients in Meniscectomy group and 28 patients in Repair group. There were no significant differences in the preoperative demographic data, kellgren Lawrence grade, and arthroscopic Outerbridge grades between studied groups. Mean age was 44.56 mean BMI was 32.4, mean KLG was 1.86, and the mean Outerbridge grade was 2.4. At the final follow up both groups demonstrated a highly significant improvement compared with pre-operative score and Repair group patients achieved a better score improvement compared with Meniscectomy group patients regarding pain and symptoms subscales (p < 0.001). The detection rate of extrusion was 96.8%, cleft sign 95.2%, ghost sign 93.6% and the axial-radial defect sign 39.6%; 22.2 % of MMPRT cases had SPONK. Conclusion: Transtibial pullout repair of medial meniscus posterior root tear demonstrated a significantly better subjective clinical outcome compared to partial meniscectomy regarding the short-term follow up, and magnetic resonance imaging is a reliable, accurate and effective tool in the diagnosis of medial meniscus posterior root tears. |
