“…Of the eight level IV studies (Table 2) included in this systematic review, all studies focused on repair of MMPRTs. [6][7][8]21,24,[30][31][32] All studies showed improvement in clinical outcomes for repair of MMPRTs. Lee et al, Liu et al and Nha et al 6,24,32 reported that a significant improvement in both radiographic and clinical outcomes with patients undergone repair treatment.…”

“…Three studies used second-look arthroscopy to evaluate surgical outcomes. 8,21,24 Seo et al 8 found that all patients showed clinical improvement despite findings of incomplete or failed healing on second-look arthroscopy after repairing. However, Lee et al 30 reported that the healing status of the repaired meniscus may relate to clinical outcomes, the stable healed meniscus showed better clinical outcomes and have less complaint compared with unhealed meniscus.…”

“…Moon et al 7 identified varus alignment, and degree of cartilage damage as worse prognostic factors for MMPRTs repair, increased meniscus extrusions provided patients with a clinical benefit. By cartilage damage of the medial compartment in patients postoperatively, Kodama et al 21 suggested that early repair surgery for MMPRTs should be undertaken for patients with mild osteoarthritic knee.…”

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.

PurposeThe aim of this study was to evaluate the role of a novel total meniscal implant in promoting meniscal regeneration and protecting articular cartilage in a rabbit model for 3 and 6 months.MethodsThirty‐six New Zealand rabbits were selected and divided into poly(ɛ‐caprolactone) (PG‐Pg) scaffold group, meniscectomy group and sham group. In this study, it was investigated whether PG‐Pg scaffold can prevent articular cartilage degeneration and promote tissue degeneration, and its mechanical properties at 3 and 6 months after surgery were also explored.ResultThe degree of articular cartilage degeneration was significantly lower in the PG‐Pg scaffold group than in the meniscectomy group. The number of chondrocytes increased in the PG‐Pg scaffold at 3 and 6 months, while a gradual increase in the mechanical properties of the PG‐Pg stent was observed from 6 months.ConclusionThe PG‐Pg scaffold slows down the degeneration of articular cartilage, promotes tissue regeneration and improves biomechanical properties after meniscectomy. This novel meniscus scaffold holds promise for enhancing surgical strategies and delivering superior long‐term results for individuals with severe meniscus tears.Level of EvidenceNA.

PurposeMedial meniscus posterior root tears (MMPRTs) occur most frequently in middle‐aged and older adults. However, this serious condition can also occur in younger patients. The purpose of this study was to compare anterior cruciate ligament (ACL) degeneration and sagittal medial tibial slope in young adults with and without MMPRT. MethodsEighteen healthy volunteers, 18 young patients (20–49 years of age), and 30 middle‐aged and older patients (50–70 years of age) with MMPRT repair were included in the study. Sex, body mass index (BMI), femorotibial angle, ACL degeneration, and medial tibial slope angle were compared among the groups. ACL degeneration and medial tibial slope angle were assessed using magnetic resonance imaging. ResultsIn the healthy volunteer group, the young patient group, and the older patient group, the medial tibial slopes were 3.5° ± 1.4°, 6.1° ± 2.7°, and 7.2° ± 1.9°, respectively, and the ACL degeneration rates were 5.6%, 38.9%, and 43.3%, respectively. Young patients with MMPRT had significantly steeper medial tibial slopes and ACL degeneration compared to those of the healthy volunteers (P < 0.05). The parameters of young patients were similar to those of older patients with MMPRT. In the multivariate logistic regression analysis, BMI, medial tibial slope, and ACL degeneration were significantly associated with MMPRT in young patients. ConclusionBMI, steep medial tibial slope, and ACL degeneration contribute to MMPRT development in younger patients. Level of evidenceLevel III.
