Menisci play an important role in the biomechanics of knee joint function, including loading transmission, joint lubrication, prevention of soft tissue impingement during motion and joint stability. Meniscal repair presents a challenge due to a lack of vascularization that limits the healing capacity of meniscal tissue. In this review, the authors aimed to untangle the available treatment options for repairing meniscal tears. Various surgical procedures have been developed to treat meniscal tears; however, clinical outcomes are limited. Consequently, numerous researchers have focused on different treatments such as the application of exogenous and/or autologous growth factors, scaffolds including tissue-derived matrix, cell-based therapy and miRNA-210. The authors present current and prospective treatment strategies for meniscal lesions.One of the most common knee injuries, especially in athletes, is a meniscal tear. There are two wedge-shaped pieces of fibrocartilage that act as shock absorbers between the thighbone and shinbone (menisci). The menisci help to transmit weight from one bone to another and play an important role in knee stability. The challenge for researchers and clinicians is to repair meniscal injuries, despite the lack of vascularization. The authors discuss the available approaches for repairing meniscal tears. Non surgical and surgical procedures are reviewed, clarifying their clinical outcomes. Other approaches to tissue engineering are also discussed. Using the patient's cells may be a potential strategy to repair meniscal injuries and improve the durability of the knee joint. |
