“…In another study, Moon et al 19 found no significant difference in postoperative clinical scores between patients with reduced or maintained meniscus extrusion and those with increased meniscus extrusion; however, the progression of osteoarthritis was delayed in the patients with reduced or maintained meniscus extrusion. Although, Yanagisawa et al 17 reported that the radiographic findings did not significantly differ between increased meniscus extrusion group and reduced or maintained meniscus extrusion group, the postoperative K-L grade was significantly worse than the preoperative K-L grade in the group with increased meniscal extrusion at 1 year postoperatively. These results indicated that the progression of arthritic changes can be prevented by preventing meniscal extrusion after MMPRTs repair.…”

Purpose: To report of efficacy repair treatment for meniscus posterior root tears repair. Methods: We systematically searched databases including PubMed, Embase, and Cochrane Library for relevant articles. Coleman Methodology Score was used for a quality assessment of the included studies. A meta-analysis was performed to analyze for efficacy of MMPRTs repair. Results: Twenty-two studies, 14 level III and 8 level IV, were included in this systematic review, with a total of 926 cases. Studies comparing repair with either meniscectomy or conservative treatment found greater improvement and slower progression of Kellgrene–Lawrence grade with meniscal repair. Decreased meniscus extrusion is beneficial to the prognosis of patients undergoing MMPRTs repair. As treatment efficacy, the Lysholm score increased 28.87 (P < 0.001), IKDC score increased 31.73. The overall pooled event rates of progression of K-L grade is 0.200. Difference of Lysholm score and IKDC score between repair and meniscectomy were 8.72 and 9.67. Conclusions: The clinical subjective score after MMPRT repair was significantly improved compared with the preoperative status. Considering the progression of joint K-L grade, it can prevent the progression of arthrosis to some extent, but not completely. Decreased meniscus extrusion is beneficial to the prognosis of patients undergoing MMPRTs repair. Based on these results, MMPRTs repair cloud result favorable outcomes.

PurposeMedial meniscus posterior root tears (MMPRT) are a risk factor for knee osteoarthritis. The predominant treatment for MMPRT is transtibial pullout repair, and loop suture remains the gold standard procedure. This study aimed to investigate the structural properties of the meniscus‐suture‐tibia (MST) complex after loop stitch using ultra‐high molecular weight polyethylene (UHMWPE) suture tape of different thicknesses.MethodsThis study used 20 fresh porcine MMPRT model knees. All specimens were randomised into two treatment groups: (1) pullout repair using 1.3 mm suture tape (thin group, n = 10; 1.3 mm PERMATAPE, Mitek Sports Medicine) fixation and (2) pullout repair using 2.5 mm suture tape (thick group, n = 10; 2.5 mm PERMATAPE, Mitek Sports Medicine) fixation. The single‐loop stitch MS technique was utilised. The MST complex specimens were placed on a tensile tester. The structural properties of the MST complex (yield load, maximum load, liner stiffness, and elongation at failure) were identified.ResultsNo significant differences were found between the thin and thick groups in terms of maximum load (108.8 ± 49.6 vs. 90.1 ± 33.6 N; p = 0.34), yield load (43.8 ± 15.2 vs. 39.4 ± 15.5 N; p = 0.53), liner stiffness (12.6 ± 8.4 vs. 11.2 ± 5.5 N/mm; p = 0.45), and elongation at failure (27.1 ± 19.4 vs. 19.9 ± 10.0 mm; p = 0.32).ConclusionThe structural properties of the thickness of the different UHMWPE were comparable in MMPRT repair. Additionally, 1.3 mm PERMATAPE may demonstrate similar repair potential as 2.5 mm PERMATAPE.Level of EvidenceLevel Ⅳ.

Purpose The long-term changes in the dynamics of the medial meniscus after transtibial pullout repair for medial meniscus posterior root tears (MMPRTs) are not completely understood. Thus, the aim of this study was to investigate the efects of transtibial pullout repair on MMPRTs and whether the efects would be sustained. Methods Nineteen knees with MMPRTs that were treated by trans-tibial pullout repair were enrolled in this study. Medial meniscus extrusion (MME) was measured by ultrasonography during knee extension (no weight-bearing with the knee at 0° extension: NW0°) and 90° lexion (no weight-bearing with the knee at 90° lexion: NW90°) with the patient in the supine position and with full weight-bearing (FW0°) preoperatively and at 3 and 12 months postoperatively. The clinical outcomes were assessed using the Knee Injury and Osteoarthritis Outcome Score, Lysholm score, and International Knee Documentation Committee score. ResultsThe diference in MME with NW0° was not statistically signiicant between the preoperative (3.4 ± 1.0 mm) and 12-month postoperative (3.7 ± 0.6 mm) time points. The MME with NW90° at 3 (2.1 ± 0.7 mm) and 12 months (2.9 ± 0.6 mm) postoperatively were signiicantly lower than the preoperative values (3.4 ± 0.8 mm) (P < 0.05). However, the value signiicantly increased from 3 to 12 months postoperatively (P < 0.05). The MME with FW0° at 12 months postoperatively (4.3 ± 0.6 mm) was signiicantly larger than that at pre-operatively (3.6 ± 0.9 mm) (P < 0.05). All the patients' clinical conditions were signiicantly improved at 12 months postoperatively when compared to their preoperative clinical conditions. Conclusion Surgery did not reduce the extrusion in the no weight-bearing and weight-bearing positions at knee extension, and these values increased in the postoperative period. In addition, while the surgery reduced the extrusion in the knee lexion position, the restoration achieved by the surgery was not sustained in the long term. Level of evidence: Level IV.
