Although in mild/moderate knee OA there is still no specific treatment targeting ME, the established conservative and operative treatment modalities seem equally successful in delaying the progression of OA and improving symptoms when ME is also present.

To the best of our knowledge, the exact clinical significance of ME after ACLR has not yet been clearly elucidated, although efforts are continuously being made to minimize this phenomenon. Reference article, Radiopaedia.org (Accessed on 01 May 2023) https://doi.org/10.53347/rID-70702. When we talk about the meniscus, only about 30 % of the meniscus has an intact blood supply and is called the red zone. The remaining part of the meniscus does not have a blood supply and thus, once injured or torn, it cannot heal or be treated. So whether ayurvedic, homeopathic or allopathic medication, none of them can really help. This post will carry two messages, both equally important. Many techniques have been described for meniscal transplantation, but the most commonly used are (a) the suture-only technique, (b) bone-plug technique, (c) keyhole technique and (d) bridge-in-slot technique [102, 104, 111]. However, the incidence of severe knee OA is much higher in patients who have been subjected to ACLR than individuals with intact ACL [86, 87]. Google Scholar, Magnusson K, Turkiewicz A, Kumm J, Zhang F, Englund M (2020) The relationship between MRI features and knee pain over 6 years in knees without radiographic osteoarthritis at baseline. Tears in this area are typically more likely to heal on their own. Recovery time can be lengthy with either one. Surgery is a very effective way to repair a torn meniscus.

Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Most people will need to perform exercises following surgery. Currently, MPRT repair constitutes the treatment of choice, since it restores the hoop tension and the joint kinematics [65], halts the progression of OA and lowers the rate of arthroplasty [66, 67]. Arthrosc J Arthrosc Relat Surg Off Publ Arthrosc Assoc N Am Int Arthrosc Assoc 26(12):16331640, Jang SH, Kim JG, Ha JG, Shim JC (2011) Reducing the size of the meniscal allograft decreases the percentage of extrusion after meniscal allograft transplantation. Slowly lower the body, keeping the foot flat. A meniscus injury is a tear in one of the menisci within the knee. The primary site of destruction is the soft tissue fibers which couple the deep layers of the ACL to the LM and the LM to the tibial plateau. Finally, we provide a proposed treatment algorithm based on the information retrieved from the literature that could help guide clinicians in the management of ME on the aforementioned knee pathologies (Fig. PubMed Central Persistent hoop and shear stresses create complex tears in the posterior horn and During this procedure, the surgeon inserts a tiny camera (called an arthroscope) through a small incision into your knee. A critical review of the literature. Correct estimation of the allograft size is also important. Recovery time is 6 to 8 weeks with conservative treatment. AJR Am J Roentgenol 183(1):1723, Muzaffar N, Kirmani O, Ahsan M, Ahmad S (2015) Meniscal extrusion in the knee: should only 3 mm extrusion be considered significant? Feeling like your knee might give out beneath you. It was also shown that after ACLR, without concomitant tears of the menisci, the anteroposterior and radial extrusion of the MM tended to increase compared with preoperative levels, but all measurements remained below the threshold value of 3mm [24, 44, 95]. A systematic review of radiological outcomes. Most transplantations have been performed with the bone-plug technique because previous studies have shown its superiority in load-bearing function, resistance to hoop stresses, similar contact mechanics to endogenous menisci and lower extrusion rates compared with the other techniques [109, 111]. Your doctor will likely recommend physical therapy. A nonsurgical treatment approach typically involves rest and avoiding activities that trigger symptoms. First, surgery is rarely necessary for degenerative meniscus tears. Theres an inner (medial) meniscus and an outer (lateral) meniscus. Chin Med J (Engl) 132(21):25502558, Goto N, Okazaki K, Akiyama T, Akasaki Y, Mizu-uchi H, Hamai S et al (2019) Alignment factors affecting the medial meniscus extrusion increases the risk of osteoarthritis development. [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. Although there is still controversy in the literature in respect of the optimal cutoff value, a threshold of 3mm is considered significant. Meniscus tears are a very common knee injury, especially among athletes. Meniscal extrusion (ME) is a radiological finding, especially in magnetic resonance imaging (MRI) scans, for which there has been growing interest in recent years. Knee 26(6):12921298, Zhang ZZ, Zhou YF, Luo H, Zhang HZ, Chen Z, Jiang C et al (2020) A novel surgical technique for arthroscopic repair of type II posterior lateral meniscal root tear. (D) After the 2 suture limbs have been tied arthroscopically forming a circumferential compression stitch. However, evaluation by absolute value alone may be limited due to differences in implant size, bone and cartilage condition, and individual patient characteristics.

Your doctor will bend your knee, then straighten and rotate it. Getting hit or tackled can make you twist your knee, tearing the cartilage. People who tear a meniscus often feel like something has popped in their knee at the time of the injury. Most often, the meniscus tears during a sudden motion in which your knee twists while your foot stays planted on the ground. Knee 24(6):14081413, Phua JKS, Razak HRBA, Mitra AK (2020) Arthroscopic procedures could delay the need for a subsequent knee arthroplasty in older patients with end-stage osteoarthritis.

Depending on your symptoms, your doctor may recommend a special knee brace or other mechanisms to limit your joint movement and stabilize the knee.

If your injury doesnt improve with RICE, NSAIDs and physical Using the back of a chair for support, stand upright. The inner two-thirds of the meniscus, however, lacks a blood supply.

It is known that ACL and meniscal function cannot be fully restored even after surgical repair [86, 90]. A novel technique has been developed based on a measurement grid in order to determine the precise aperture of the tibial tunnel. In addition, it has been shown that after lateral MAT, the extrusion is correlated with the progression of joint space narrowing (JSN) during long-term follow-up, while after medial MAT, JSN is observed during medium-term follow-up [114]. WebThe outside one-third of the meniscus has a rich blood supply. This thinner cartilage can tear more easily. The goal of the anatomic reconstruction of the ACL rupture is to replicate the normal knee anatomy. If your symptoms persist after 3 months or your symptoms become significant, your doctor may recommend surgery to repair the tear. A torn or strained meniscus is generally treated with rest, ice, over-the-counter anti-inflammatory medicines and physical therapy. Debieux et al. The menisci are pads of cartilage in the knee joint. Magnetic resonance imaging (MRI) mid-coronal view of the right knee, where the tibial eminences are most prominent. To perform this exercise, a person should do the following: The red zone has a blood supply, and therefore, a meniscus injury in this area may heal on its own. People with arthritis in their knees are also more prone to meniscus tears. Here, find nine gentle exercises that may help strengthen and heal a torn meniscus. CAS Krych et al. 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].

MAT is not a simple surgical procedure, has a high learning curve, and if it is not performed under certain indications (Table 1) it fails, leaving both the surgeon and the patient dissatisfied [106, 109]. Google Scholar, Ozeki N, Seil R, Krych AJ, Koga H (2021) Surgical treatment of complex meniscus tear and disease: state of the art.

This article discusses what a meniscus injury is, including the different types of meniscus tears. We avoid using tertiary references. The aim is to strengthen the muscles surrounding the knee, such as the front thigh muscles, known as the quadriceps.
