Summary of the major findings of the included studies regarding meniscal tears management.
| Study | Material model | Experimental design | Conclusion |
|---|---|---|---|
| Vadher et al., 2006 [13] | Axisymmetric model | Shear stress in articular cartilage following various amounts of meniscus removed | Little changes in shear stress in the cartilage with up to 20% of meniscus removal, while meniscectomies > 20% increases drastically the shear stress in the cartilage |
| Liu et al., 2022 [18] | CT- and MRI-based knee model | Biomechanical behavior of the knee after partial meniscectomy in adults with complete discoid lateral meniscus | Meniscus width < 8 mm increases the contact stress significantly, while meniscus width of 8 to 10 mm provides a better biomechanical environment |
| Li et al., 2020 [19] | CT- and MRI-based knee model | Medial meniscus degeneration on the progress of the knee osteoarthritis | Degeneration of the medial meniscus leads to further increases of shear stress and also increases the shear stress in the healthy (lateral) compartment |
| Chen et al., 2023 [20] | MRI-based model | Internal force relationship of the knee after meniscus repair compared with different options of partial meniscus resection | Changes in shear stress within joint after resection of the superior leaflet of the meniscus is quite similar with meniscus repair and better when compared with the resection of the inferior leaflet of the meniscus |
| Wang et al., 2021 [21] | MRI-based model | Knee biomechanics after different repair methods for PRLM tears | Contact mechanics and kinematics of the knee after repair of PRLM can be similar to those of an intact knee joint |
| Xu et al., 2022 [22] | CT- and MRI-based knee model | Biomechanical characteristics of the knee joint after different patterns of PRMM tears versus meniscal repair | Loss of integrity of PRMM increase the load on the medial tibiofemoral articular cartilage, while meniscal repair restores the mechanical properties of the meniscus |
| Steineman et al., 2020 [23] | Imaged cadaveric knee specimens | Knee mechanics after non-anatomic placement of PRMM repair | Posterior placement of PRMM repairs results in greater changes to cartilage and meniscus mechanics, while anterior placement of PRMM repairs nearly restores contact tibiofemoral area |
| Steineman et al., 2022 [24] | Imaged cadaveric knee specimens | Knee mechanics after anatomic repair of PRMM compared with loosened repairs and untreated tears | Loosened repairs of PRMM can restore mechanics better than untreated meniscal root tears |
| Nabiyev et al., 2023 [25] | 3D computer model | Knee biomechanics after oblique-vertical suture compared vertical suture technique for longitudinal meniscal tears | Oblique-vertical suture technique provide superior grip on the radial and circular fibers of the meniscus and a higher contact area compared to the classical vertical suture |
| Shriram et al., 2017 [26] | MRI-based cadaveric knee model | Cartilage contact pressures and distribution with the use of artificial meniscal implant versus meniscectomy | Anatomically shaped artificial implant induces lower peak cartilage contact pressure and reduces the cartilage regions loaded |
Abbreviations: CT, computed tomography; MRI, magnetic resonance imaging; PRLM, posterior root lateral meniscus; PRMM, posterior root medial meniscus.
