“…In their investigation, Kashihara et al [13] reported that when ACLR was performed with posterior segment lateral meniscus repair via an all‐inside technique, meniscal extrusion was found to significantly increase by nearly 1 mm at a mean 3 months follow‐up ( p < 0.001). Meanwhile, Tsujii et al [33] evaluated lateral and posterior meniscal extrusion in patients undergoing ACLR with either concomitant radial/flap lateral meniscus tear repair ( n = 40), longitudinal lateral meniscus tear repair ( n = 43), or an intact lateral meniscus ( n = 40) at 3 weeks post‐operatively and then at final follow‐up (mean 3.5 years). The authors reported no significant differences when comparing preoperative extrusion values to those at 3 weeks in coronal (n.s.)…”

Purpose To perform a systematic review of biomechanical and clinical outcomes following lateral meniscus posterior root (LMPR) repair with concomitant anterior cruciate ligament reconstruction (ACLR). Methods A literature search was performed systematically using PubMed, Embase, and Medline databases in April 2022. The search included the following terms combined with Boolean operators: 'Meniscus repairs', 'Meniscal Repair', 'Posterior Horn', 'Root', 'Radial'. Inclusion criteria consisted of level I-IV human clinical and biomechanical studies reporting biomechanical data and/or outcomes following LMPR repair in the setting of ACLR. Results Three biomechanical studies, all utilizing a transtibial pullout technique, were identiied, all of which reported signiicant improvement in joint contact pressures and mechanics and 3/4 of which reported signiicant improvement in anterior or rotational stability with LMPR repair. Five clinical studies, consisting of 146 patients (mean age 28.5 ± 1.1 years) undergoing LMPR repair, were identiied with an average follow-up of 19.1 months (range 6.2-46 months). Across all clinical studies, Lysholm and International Knee Documentation Committee (IKDC) scores were found to improve postoperatively, with 3/4 reporting signiicant improvement in Lysholm (all, p ≤ 0.001) scores and 3/5 reporting signiicant improvement in IKDC scores when compared to preoperative values (all, p ≥ 0.004). Meniscal extrusion decreased signiicantly following repair in 2/4 studies (all, p ≤ 0.001). Conclusions Biomechanically, transtibial pullout repair of the LMPR restored joint contact pressures and joint mechanics to intact levels when performed with concomitant ACLR. Clinically, LMPR repair with concurrent ACLR resulted in improved Lysholm and IKDC scores. These indings enable surgeons to determine optimal treatment plans and discuss realistic outcomes with patients when encountering LMPR injuries. Level of evidence IV.

“…Therefore meniscal extrusion should be examined in both coronal and sagittal slices in conventional MRI. 11,12 Additionally, MRI examination immediately after surgery is useful to assess postoperative changes. 13 Assessing the healing status of the repaired meniscus is still difficult in conventional MRI, but T2 mapping can differentiate the healing status.…”
