Horizontal tears can be sewn together rather than removing the damaged portion. This leads to decreased contact area and increased contact pressure and ultimately results in joint overloading and degenerative changes in the knee similar to a total meniscectomy state. Includes interactive tool to help you decide. This provides a clear view of the inside of the knee. Meniscal intra-substance signal abnormalities are defined as an increased signal that does not fulfill the criteria for a meniscal tear according the "two-slice-touch" rule (i.e., it does not reach the meniscal surface on two consecutive views) and is a common finding on routine MRI of the knee (Fig. Although C, a vertical tear, is commonly used to describe such an appearance, the better answer is D, a longitudinal tear. Symptoms. 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. If the fracture is stable or closed where the bones do not move out of alignment then simple immobilization with the use of a sling, splint or cast for a few weeks allowing the fracture to heal may be enough. Successful outcome and patient satisfaction after medial meniscal root repair are established initially upon appropriate diagnosis and patient selection. ICD 9 Codes: 717.4 derangement of the lateral meniscus 717.3 derangement of the medial meniscus 836.0 lateral meniscus tear 836.1 medial meniscus tear Case Type / Diagnosis: Functional Anatomy: The menisci are semi lunar shaped cartilages on the medial and lateral sides of the knee joint.

The second patient reviewed in this video is an 11-year-old girl who fell while playing tag and hit the front of her left lower leg. Even better would be to describe a peripheral longitudinal tear extending to the tibial surface within the posterior horn of the medial meniscus! Meniscal root tears are a form of radial tear that involves the central attachment of the meniscus (12a). A 501(c)(3) non-profit organization. Scuderi G, Tria A.

Posterior Horn Meniscus Tears A tear of the anterior horn of the lateral meniscus is damage to the front part of one of the two structures that act as shock absorbers between the thigh bone and the lower leg, explains The Steadman Clinic. 12 Sources By Jonathan Cluett, MD More often, the patient will complain of joint line pain with a minor traumatic event, such as squatting. There will also be skin discoloration and visible deformity at the site of the injury. The double posterior cruciate ligament (PCL) sign appears on sagittal MRI images of the knee when a bucket-handle meniscal tear (medial meniscus in 80% of cases) flips towards the center of the joint so that it comes to lie anteroinferior to the posterior cruciate ligament (PCL) mimicking a second smaller ligament.. A double posterior cruciate ligament sign from a torn medial meniscus can . 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.

Collateral and cruciate ligaments are intact. Am J Sports Med 2004;32:67580. Meniscal tear | Radiology Reference Article | Radiopaedia.org In the present case, a full-thickness radial tear of the medial meniscus is visualized (Fig 1).An arthroscopic torpedo shaver (Arthrex, Naples, FL, U.S.A.) is used to debride the meniscus tear edges back to a healthy, stable rim (Fig 2).For improved access to the medial meniscus, an 18-gauge spinal . The arthroscope is inserted near the knee via a tiny incision. (12a) A radial tear (arrow) truncates the central attachment/root of the posterior horn of the medial meniscus on this fat suppressed proton density-weighted coronal image. Arthroscopy. Your doctor will bend your knee, then straighten and rotate it. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. Both longitudinal and radial tears may appear vertical on MR images (5a,6a), but longitudinal tears extend parallel to the c-shaped circumference of the meniscus, whereas radial tears lie perpendicular to the meniscal circumference. Oblique tears commonly cause flaps and flaps are generally not good. Medial meniscal root tears are more frequently diagnosed in patients who are older than 40 years, are overweight and cannot recall an inciting event. Arthroscopy 2010;26:13689.

Meniscus Tear of the Knee: Causes, Symptoms, and Diagnosis - Healthline Doctors typically provide answers within 24 hours. However, coronal sections may reveal the presence of meniscal extrusion or vertical defects, and sagittal sections may reveal the ghost sign (absence of an identifiable meniscus or increased signal replacing the normal hypointense signal of meniscal tissue). 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. Scholten RJ, Deville WL, Opstelten W, Bijl D, van der Plas CG, Bouter LM. These meniscus tears are displaced into the tibia or femoral recesses and can be often difficult to diagnose intraoperatively.

As recognition of the critical function of the menisci in normal biomechanical function of the knee has grown, attempts at preserving meniscal tissue via repair as opposed to partial meniscectomy have also gained favor. These tears can be challenging to recognize on MRI,9 but are important to diagnose since they are often highly symptomatic due to a reactive synovitis. The medial meniscus is the cushion that is located on the inside part of the knee. A flap tear is a descriptive term that refers to a situation where the meniscus tears within its midsubstance, usually in a predominantly horizontal pattern, and then the upper or lower component of the torn meniscus becomes displaced from its site of origin (14a).8 These tears are most common at the medial meniscal body, and when displaced, the flap component may migrate into the superior or inferior meniscal gutter (15a,15b).

Adjunctive measures to promote vascularity and healing at the repair sites are also recommended. These are often 'bucket-handle tears', in which there is a vertical or oblique tear in the posterior horn running toward the anterior horn,5 forming a loose section which remains attached anteriorly and posteriorly.1 In older patients, tears are generally due to degeneration associated with ageing and tend to be horizontal tears. I have been diagnosed with a subtle oblique tear involving Fat suppressed proton density-weighted (15a) coronal and (15b) sagittal images reveal a tibial sided flap tear of the body of the medial meniscus, with displacement of the undersurface component (arrows) into the inferior gutter.
