oblique tear of medial meniscus
In cases where a torn meniscus has locked the knee, walking will be affected. If this cartilage tears, the result is pain, stiffness, and swelling. Magnetic resonance imaging as a tool to predict reparability of longitudinal full-thickness meniscus lesions.

Grades 1 and 2 are not considered serious. The skilled interpreter of MR of the knee must do more than simply identify the presence of a meniscal tear. Proton weighted sagittal image demonstrates an example of a posterior horn medial meniscal horizontal tear (white arrow). A tear can also develop slowly as the meniscus loses resiliency. However, these patients are rare. (10a) A GRE T2*-weighted sagittal image reveals a complex tear of the posterior horn of the medial meniscus, having horizontal (arrows) and longitudinal (arrowhead) components. Posterior Horn Medial Meniscus Tear | Knee Meniscus Tear The medial meniscus is the portion of the cartilage along the inside of the knee joint (closest to the other knee). bucket-handle tear: displaced vertical tear parrot beak tear: oblique radial tear Radiographic features Plain radiograph On plain radiographs, meniscal tears are not visible. Feb 1995;11(1):29-36. Case Discussion Longitudinal tears, also known as vertical tears, occur perpendicular to the tibial plateau and parallel to the long axis of the meniscus splitting the meniscus into inner and outer parts. Oblique tear of the posterior horn of the medial meniscus On examination, there may be joint effusion, joint line tenderness, and the joint is held in a flexed position.1 in late presentations, there may be significant quadriceps wasting. Trauma to medial collateral ligament usually also involves medial meniscus. If an ACL tear is also present, meniscal repairs are more successful if the ACL is also repaired, likely due to the protection afforded by knee stability. 2nd ed.

Meniscectomy as a risk factor for knee osteoarthritis: a systematic review. When appropriate, tears that appear to involve the periphery, or red zone of the meniscus, should be described as such (9a), thereby alerting the surgeon to the fact that the tear is more amenable to repair. Magnetic resonance imaging is first line for investigating potential meniscal lesions, but should not replace thorough clinical history and examination. Your doctor will bend your knee, then straighten and rotate it.

The lateral meniscus has a symmetrical C-shape, whereas the medial meniscus is more crescentic (3a), as the posterior horn of the medial meniscus is always larger than the anterior horn. Making a medial meniscal root tear diagnosis is difficult because the typical history of locking, catching or giving way is less likely to be present. Submission to the Department of Health and Ageing. Meniscal root tears: significance, diagnosis, and treatment This piece of soft tissue often becomes torn, especially in athletes, due to quick movements and sudden trauma. The medial meniscus is on the innermost side of your knee (the C-shaped curve faces in toward your body, the opposite knee). Meniscal tears may be categorized into five common configurations, including horizontal, longitudinal, radial, oblique (parrot-beak), and complex. This makes the medial meniscus less mobile and is one reason why the medial meniscus is more prone to injury.3 In adults, only the periphery of the meniscus remains vascularized. Although a successful outcome of a meniscal root repair is predicated upon appropriate indications for the repair, not all medial meniscal root tears should be repaired. American Board of Orthopaedic Surgery Practice of the Orthopaedic Surgeon: Part-II, certification examination case mix. Walking can become difficult. 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.

Meniscal Tears - Knee & Sports - Orthobullets These tears often occur in association with ACL tears, but even if found in isolation, are highly likely to be clinically relevant, as the displaced meniscal fragment frequently results in knee locking. Presumptive subarticular stress reactions of the knee: MRI detection and association with meniscal tear patterns. Inferiorly Displaced Flap Tears of the Medial Meniscus This part of the tibia is also known as the tibial plateau. Bucket-handle tears are actually a form of longitudinal tear in which subsequent displacement of the inner rim of the tear results in a configuration that resembles the handle of a bucket (11a). Typically, complex tears are not treated with meniscus repair due to their complex nature. Each knee has two C-shaped pieces of cartilage known as menisci. The medial meniscus is C-shaped, while the lateral meniscus is more . Superior and inferior branches of the medial and lateral geniculate arteries supply the peripheral third of the menisci via the perimeniscal capillary plexus.3,4, Meniscal tears occur due to a shear force between the femur and tibia. Knee Surg Sports Traumatol Arthrosc 2009;17:11026. Knees with a deficient medial meniscus and an ACL tear have an increased anterior tibial translation of about 60% at 90 of flexion. Bucket Handle Meniscus Tear - Cleveland Clinic: Every Life Deserves These are the horns. The posterior horn is located on the back half of the meniscus. Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. Patients with ACL tears are also thought to be better candidates for meniscal repair because of the presence of serum-derived growth factors within the hemarthrosis that accompanies ACL tears.15. It has the shape of two C's. The medial meniscus is the C shape on the knee's inner side, and the lateral meniscus is the C shape on the outer side of the knee. The arthroscope is inserted near the knee via a tiny incision. (16a) Sagittal and (16b) axial proton density weighted images reveal a very large radial tear (arrows) that extends broadly across the entire width of the anterior body of the lateral meniscus. However, it may also occur in older athletes through gradual degeneration. Missouri: Mosby, 1998. An oblique tear (7a,8a) is often referred to as a parrot-beak tear, as the tear shape resembles a parrots beak. w/severe pain? for a 22 year old severe pain.

Although an X-ray will not show a meniscus tear, your doctor may order one to look for other causes of knee pain, such as osteoarthritis. Swelling or stiffness. A loose piece of cartilage can get stuck in the joint, causing the knee to temporarily lock, preventing full extension of the leg. Normal knee anatomy. Meniscus Injuries - The Steadman Clinic AJR Am J Roentgenol 1998;170:5761. The accuracy of physical diagnostic tests for assessing meniscal lesions of the knee: a meta-analysis.

Anatomy of Knee Joint in a Nutshell - DMA Edu Have swelling, stiffness or tightness in your knee. Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a).

If the knee is still painful, or if it locks, your doctor may recommend surgery. Repair is sometimes attempted even with these tear types, particularly when the patient is young and substantial loss of meniscal tissue would lead to an unacceptable risk of future arthritis.11 Repair of these challenging tear types should only be attempted when the meniscal tissue is of good quality and a stable result is achievable. These lie on the inside (medial) and outside (lateral) edges of the top of your tibia (shin bone). It is generally divided into 3 separate portions, the anterior horn, the mid-body and the posterior horn. Reciprocally, an increased force is also placed on an ACL graft with a deficient medial meniscus. More often, the patient will complain of joint line pain with a minor traumatic event, such as squatting. The amount of pain and first appearance of swelling can give important clues about where and how bad the injury is. The loss of the central attachment of the posterior horn may allow extrusion of the body of the meniscus relative to the joint (13a). Meniscal tears within the body of the meniscus or at the meniscocapsular junction represent a well-understood and manageable condition encountered in clinical practice. If you have a meniscus tear, this movement may cause pain, clicking, or a clunking sensation within the joint. The surgery requires a few small incisions and takes about an hour. The anatomic landmark for repair is anterior to the PCL footprint on the tibia. Tears present as severe pain, swelling, and possibly catching, clicking, difficulty on deep knee bending and locking of the knee in partial flexion.
