Arthroscopy 1998;14:8249. The medial meniscus transmits approximately 50% of the total joint load of the knee medial compartment, thus protecting the articular cartilage from excessive force. Although surgical repair has led to improved patient-reported function, there are conflicting reports on the progression of cartilage degeneration. The goal of meniscal root repair is to restore the joint to a near native function of the meniscus and prevent cartilage degradation associated with nonsurgical treatment or meniscectomy. Anti-inflammatory drugs such as aspirin, ibuprofen, and naproxen help reduce pain and swelling. Call us at(386) 255-4596to schedule an appointment.

They may not even be apparent with an arthroscopic examination. Lufkin R. The MRI manual. Radial tears, because they are oriented perpendicular to the c-shaped fibers of the meniscus, have a devastating effect upon meniscal function. The one towards the back of leg is the posterior horn. Knee Surg Sports Traumatol Arthrosc 2011 Aug 11. If mechanical symptoms are present in this subset of patients, a partial or subtotal meniscectomy may improve symptoms; although, these tears are not usually associated with traditional meniscal-based mechanical symptoms. We use cookies to ensure that we give you the best experience on our website. Figure 1. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. On MRI, meniscal tears are evident as a linear signal intensity that extends through the meniscal substance to a free edge17 (Figure 4). Barrett GR, Field MH, Treacy SH, Ruff CG. While visualization of the meniscal root may be difficult due to MRI slice size, type of MRI and strength of MRI, an extrusion larger than 3 mm highly correlates with a root tear. Treatment of meniscal tears includes simple observation, meniscectomy, and meniscal repair. Description of Medial Meniscus Tear The medial meniscus is an important shock absorber on the inside (medial) aspect of the knee joint. Sometimes these tears require surgical repair.

If this cartilage tears, the result is pain, stiffness, and swelling. It is therefore quite important in treatment planning for the pre-operative MR to provide information that can be used to determine whether meniscal repair rather than partial meniscectomy is to be performed. Illustration and photo show a camera and instruments inserted through portals in a knee. It is caused by direct impact in contact sports or twisting.

By the time people reach their twenties or thirties, intrasubstance changes of the meniscus tissue are common. A referral to an orthopedic physician should result in guidance it means you need to see in orthopedist and get an opinion as to whether. Primary repair of medial meniscal avulsions: 2 case studies. There will also be skin discoloration and visible deformity at the site of the injury. A tear can also develop slowly as the meniscus loses resiliency. Nonsurgical treatment is an option for elderly patients, those with significant comorbidities and those with advanced OA (Outerbridge grade 3 or 4 chondromalacia of the ipsilateral compartment). Of course, if a displaced meniscal fragment is identified, the tear is by definition unstable. Extrusion of the medial meniscus (MM) is associated with knee joint pain in osteoarthritic knees. The Thessaly test for detection of meniscal tears: validation of a new physical examination technique for primary care medicine. The medial meniscus is an important secondary stabilizer of the knee. 12 Sources By Jonathan Cluett, MD MR imaging: effectiveness and costs at triage of patients with nonacute knee symptoms. Presumptive subarticular stress reactions of the knee: MRI detection and association with meniscal tear patterns. This is because this area has rich blood supply and blood cells can regenerate meniscus tissue or help it heal after surgical repair. A meniscus tear can lead to knee instability, an inability to move the knee normally, and chronic knee pain. Principles and decision making in meniscal surgery. A meniscectomy requires less time for healing approximately 3 to 6 weeks.

Aging is also a risk factor due to general wear and tear of the knees. A magnetic resonance imaging (MRI) scan is often used to diagnose meniscal injuries. Flaps cause mechanical instability - meaning they interrupt the smooth function of the knee joint and will make your knee joint feel unstable. Deep leg presses and squats greater than 70 of knee flexion should be avoided for at least 4 months after surgery. Symptoms of a meniscus tear. (9a) This irregular tibial surface tear (arrow) clearly lies within the peripheral, red zone, of the meniscus. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. Posterior medial meniscal root tears are often times degenerative, but these can also occur with multi-ligament knee injuries in the acute setting. Currently, routine MR images do not reveal signal intensity differences between the red and white zones of the menisci. what is the best possible treatment? 8 Ruff C, Weingardt J, Russ P, Kilcoyne R. MR imaging patterns of displaced meniscus injuries of the knee. Clin J Sport Med 2009;19:912. The anterior horn of the medial meniscus demonstrates half of the normal anatomic 'bow-tie configuration'. Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites.

A tear in this "red" zone may heal on its own, or can often be repaired with surgery. MR imaging is reliable in the detection of meniscal tears and identification of meniscal fragmentation and displacement [1, 2, 3, 4].Displaced meniscal fragments are often clinically significant lesions requiring surgical intervention and, therefore, are important to identify. or ? The absent bow tie sign in bucket-handle tears of the menisci in the knee. So the injury as seen in MRI scan means there is an tear in the medial meniscus towards the posterior side, that is towards the back of joint. Knee Surg Sports Traumatol Arthrosc 2009;17:11026.

AJSM 2002; 30:589-600. They will manipulate your leg into various positions, observe you while you walk, and bend at the knee. With regard to tear morphology, the classic ideal candidate for meniscal repair is the peripheral longitudinal tear. A medial meniscus tear on the inside of the knee is more common.

Thessaly test: The clinician holds the patient's outstretched hands for support, while the patient stands flat-footed with their knee flexed to 20 degrees and rotates their body and knee three times, internally and externally. A meniscus tear is an injury to one of the bands of rubbery cartilage that act as shock absorbers for the knee. Knee Surg Sports Traumatol Arthrosc 2008;16:4826. AJR 2000; 174:161-164. Those that extend through the entire width of the meniscus are particularly harmful (16a,16b), and even if such tears appear stable following repair, they are unlikely to regain the ability to provide hoop stress to the meniscus.13 Radial tears have therefore classically been treated with partial meniscectomy, though evolving surgical techniques have led to successful reports of the repair of radial tears that communicate with the meniscal periphery.11 A recent report has even described the successful repair of radial tears of the medial meniscal root,14 utilizing a tibial tunnel through which sutures are placed in the avulsed meniscus, a technique similar to that used in patients undergoing meniscal transplantation. Knee arthroscopy is one of the most commonly performed surgical procedures. When people talk about torn cartilage in the knee, they are usually referring to a torn meniscus. A tear can also develop slowly as the meniscus loses resiliency. Disclosures: Blake and Johnson report no relevant financial disclosures. With the realization that even partial meniscectomy leads to accelerated osteoarthritis,2 surgeons have increasingly turned to meniscal repair. Tears of the posterior medial meniscal root have shown to disrupt the normal motion of the knee, resulting in degenerative arthritis. Meniscal tear configurations: categorization with MR imaging. This means that athletes, especially those who participate in contact sports like football, are at a higher risk of sustaining this injury.

Because these two tear patterns differ greatly in prognosis and treatment approach, vertical is therefore not the preferred descriptor for such meniscal tears, unless paired with the proper category, such as vertical longitudinal.
