(11a) A 3D illustration of a bucket handle tear demonstrates that these tears actually are longitudinal in nature (arrows), coursing parallel to the c-shaped fibers of the meniscus. Inferiorly displaced flap tears of the medial meniscus: MR appearance and clinical significance. As the risk of osteoarthritis is increased if meniscal structures are not optimally functional,7 it may also be appropriate to refer all young patients for opinion if symptoms do not rapidly improve. Medial and lateral menisci are crescent-shaped fibrocartilage structures that provide joint congruity, stabilization and lubrication and act as shock absorbers for joint preservation. In addition to the root tear, the MRI often shows chondral loss or fissuring, other areas of meniscal tearing, bone marrow edema or osteophyte formation (Figure 5). oblique ligament, and the . This puts tension on a torn meniscus. This technique allows for anatomic reduction and fixation of the meniscal root by restoring the joint contact pressure and area similar to the intact state.

Brain Res Rev 2009;60:187201. The menisci help to transmit weight from one bone to another and play an important role in knee stability. Meniscal pain occurs during torsional, weight bearing knee movements (classically pivoting on the knee while walking) as a sharp stab lasting several seconds, often followed by a dull ache for several hours. Meniscus Surgery. A meniscus tear can occur when the knee is suddenly twisted while the foot is planted on the ground. (Right) Flap tear. Although the pain improved, the patient could not flex her knee joint deeply. Pain may wake the patient from sleep as the tender medial aspect of the knee strikes the other side as the patient rolls over in bed. How to treat an oblique tear of the posterior horn of the medial meniscus? If the knee is still painful, or if it locks, your doctor may recommend surgery. Conservati For a young person arthroscopic meniscal repair is the best solution. Imaging tests X-rays. Magnetic resonance imaging of the knee menisci. Of note, drilling tibial tunnels may improve healing of the meniscus-bone interface due to the presence of progenitor cells and growth factors derived from the bone marrow. Meniscus tears are among the most common knee injuries. 2nd ed. If the tear is associated with arthritis it will typically improve over time as the arthritis is treated.

Pathology - a tear that has developed gradually in the meniscus. McMurray test: The patient lies supine on the bed with the hip and knee both flexed. pivoting). New advances in musculoskeletal pain. With the foot as close to the hip as possible, the clinician holds the knee joint (with fingers along the joint line) with one hand, and the other hand rotates the tibia internally and externally while extending and flexing the knee. Description of Medial Meniscus Tear The medial meniscus is an important shock absorber on the inside (medial) aspect of the knee joint. In comparison , however, meniscal root tears (MRTs) often go unnoticed and represent a unique injury pattern with unique biomechanical consequences. These can occur through either a contact or non-contact injury for example, a pivoting or cutting injury. They will manipulate your leg into various positions, observe you while you walk, and bend at the knee. Knee Surg Sports Traumatol Arthrosc 2008;16:4826.

Scholten RJ, Deville WL, Opstelten W, Bijl D, van der Plas CG, Bouter LM. When displacement is not evident on MR images, additional criteria that suggest tear instability include the presence of fluid signal intensity within the tear on T2-weighted images, a tear that is greater than 10mm in length, and tears with complex patterns (10a). 2nd edn. Knee Surg Sports Traumatol Arthrosc 2009;17:11026. Unfortunately, general practitioners cannot currently order Medicare funded MRI, although this may change with The Royal Australian College of General Practitioners recent submission to the Australian Government Department of Health and Ageing. 2 Jaureguito JW, Elliot JS, Lietner T.

A meniscal tear can heal on its own, but location is important. Meniscal root tears, less common than meniscal body tears and frequently unrecognized, are a subset of meniscal injuries that often result in significant knee joint disorders. Oblique tear of the posterior horn and body of the medial meniscus involving inferior articular surface and peripheral meniscal margin. The meniscus is a piece of C-shaped cartilage that helps cushion the knee. Longitudinal tears do not disrupt the circumferential architecture of the meniscus, and thus repair of longitudinal tears leads to a meniscus with relatively normal biomechanical function. AnteroLateral Meniscus Tear: This means your lateral meniscus is torn and in a location on the front portion of the knee. With meniscal repair, weight bearing may be severely limited for up to six weeks following surgery, and protection from heavy stress to the knee extends for up to six months.

AJSM 2003; 31:216-220. It seems that in the above knee, the biology of the medial compartment has gone off the ski slope in a degenerative fashion and reversing that ski slope fall seems to be unproven at this time, particularly in the patient with low functional demands, who is older than 40 years and who has a BMI greater than 30. J Bone J Surg Am 2006;88:6607. Oblique tears give rise to flaps which are mechanical unstable and associated with mechanical symptoms.

Depending on your duration of symptoms you can at least start off with physical therapy, a knee sleeve, and if there is arthritis present consider a c Dr. Christopher Ferguson and another doctor agree. We believe these tears are more degenerative in nature, and there is no evidence to support that by repairing these medial meniscal root tears, knee degeneration will be postponed or stopped. This puts tension on a torn meniscus. (386) 255-4596 Over 2 to 3 days, however, the knee will gradually become more stiff and swollen. Displacement of the inner rim of the tear (arrowheads) results in the classic "bucket-handle" configuration. An MMPH repair in an ACL-deficient knee showed a significant decrease in anterior-posterior tibial translation at all flexion angles except 60 compared with the ACL-deficient/MMPH tear state . As stated above, the most common cause of Posterior Horn Medial Meniscus Tear can be trauma to the knee which can be sustained due to a sporting injury, a slip and fall, a blunt trauma to the knee, and in majority of the cases natural degeneration of the meniscus due to the work load of the knee.

In this short surgical video, a degenerative meniscus tear is smoothed down with a motorized shaver during a partial meniscectomy. Arthroscopic meniscus repairs typically takes about 40 minutes. With advances in surgical techniques and instrumentation, meniscal root repair is a viable option that can restore the biomechanics and kinematics of the knee (Figure 4). Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). Lists risks and benefits of surgery for meniscus tear. Extrusion of the medial meniscus (MM) is associated with knee joint pain in osteoarthritic knees.
