See additional information. However, several studies showed that partial meniscectomy, particularly when the ME was profound [62, 63], failed to prevent the progression of OA, as it creates a meniscus-deficient state, and leads to significant functional impairment with high rates of arthroplasty [24, 60]. Finally, meniscal allograft extrusion is also associated with subchondral bone marrow lesions and cysts [2, 115]. [13] proved biomechanically that ME is possible with intact meniscal roots and that centralization of the meniscus restores the tibiofemoral contact pressures back to normal. This will reduce the stress on your knee. (ACLR+LM tears left in situ) showed narrowing of 0.33mm of the lateral joint space at 3years postoperatively, and Shelbourne et al. Cookies policy. The menisci are crescent-shaped, fibrocartilaginous structures that play a crucial role in the load transition and distribution of the contact forces along the tibiofemoral articulation. This value is identified as the optimal cutoff point for a complete PRT of the LM and has 100% sensitivity and 83% specificity [92].

This is the area of your meniscus that has some blood supply, which aids healing. There is no established optimal surgical technique at present for restoring ME to normal values, and thus there will be a strong need for more effective and refined techniques. Work up slowly to more intense exercise activity. Also consult a doctor if you continue to have pain after a course of conservative treatment. (2016).

TK and DG designed the manuscript and helped to draft the manuscript and review it. Interest in ME has grown exponentially in recent years, as it is associated with several pathologies, such as knee OA, meniscal posterior root tears (MPRT), post-anterior cruciate ligament reconstruction (ACLR) and post-meniscal allograft transplantation (MAT) [6, 23, 24]. There are two main types of arthroscopic surgery for a meniscus tear: partial meniscectomy and meniscus repair. A meniscus injury is a tear in one of the menisci within the knee. Dawson LJ, et al. WebOne of the main tests for meniscus tears is the McMurray test.

Based on these findings, they concluded that the all-inside repair of the radial tear of the LM could help maintain its dynamic behavior, thus reducing the biomechanical stress exerted on the adjacent cartilage [89]. Improper positioning of the posterior horn causes a similar deviation to the anterior horn. maceration Meniscus repair involves stitching torn pieces of a meniscus back together.

If you have surgery to repair a torn meniscus, your knee should be fully recovered after a few months of physical therapy. This pattern completely disrupts the continuity of the circumferential fibers, leading to the loss of the hoop tension and substantial ME, thus promoting rapid progression of knee OA [1, 57].

Correspondence to In another study where they examined MRI series both before and after medial MPRT, they showed that MTL disruption and ME predated the MPRT, thus emphasizing the potential role that MTL could play as a causal factor of ME, and even suggesting that disruption of MTL should be addressed alongside MPRT repair in order to reduce ME [75].
