Numerous scientific studies have systematically elucidated the special status and importance of the meniscus in the anatomy, biomechanics and function of the knee joint. As an important component of the knee joint, the meniscus has the function of cushioning stress and shock, increasing joint contact area, reducing joint surface stress, improving tibiofemoral joint adaptability, stabilizing the knee joint, and protecting and lubricating joint cartilage. It plays a vital role in preventing damage and degeneration of articular cartilage and the development and progression of osteoarthritis. Unfortunately, the meniscus is at the pivotal position of the body and the tremendous stress it carries makes it vulnerable to injury. As the most common knee disorder, meniscal injuries have been the most common cause of knee surgery. With the growing recognition of the importance of meniscal function, there is a consensus that meniscal injuries should be repaired whenever possible. To date, techniques for meniscal repair can be divided into three main categories: inside-out, outside-in, and total-inside-out meniscal repair techniques. In general, inside-out repair techniques can be used for tears in the middle 1/3 of the meniscus; outside-in repair techniques can be used for tears in the anterior horn of the meniscus; and all-in meniscal repair techniques can repair injuries in the posterior horn of the meniscus and its junction with the body. Rehabilitation after meniscal repair is also an important factor in determining its clinical outcome. In the field of meniscus surgery, there is a tendency for both physicians and patients to emphasize surgery and neglect rehabilitation.
