The younger population, particularly males with knee instability, is most commonly affected by this type of tear [56]. 3 Thornton DD, Rubin DA. However, meniscus tears do not always appear on MRIs. Knowing where and how a meniscus was torn helps the doctor determine the best treatment.. The medial meniscus is the portion of the cartilage along the inside of the knee joint (closest to the other knee). Both of these factors increase contact forces across the joint, leading to accelerated osteoarthritis and predisposing the patient to the development of subchondral insufficiency fractures.7. Grade 3 meniscus tears usually require surgery, which may include: Tips to help you get the most from a visit to your healthcare provider: Cedars-Sinai has a range of comprehensive treatment options.

Know why a new medicine or treatment is prescribed, and how it will help you. There are two menisci, a medial one on the "inside" of the knee and a lateral one on the "outside" of the knee. This region of the outer meniscus, sometimes referred to as the red zone, is thought to occupy approximately 15% of the peripheral meniscus.4 Tears that occur within the red zone of the meniscus are more likely to heal than those in the avascular, white zone of the meniscus. Other established anatomical variants include the transverse meniscal ligaments and the meniscofemoral ligaments, which mimic meniscal tears at their meniscal attachment sites. You might feel a pop when you tear the meniscus. Oblique tears commonly cause flaps and flaps are generally not good. 2013. Arthroscopy 2006;22:77180. The patient underwent a successful partial medial meniscectomy and was encouraged to seek low-impact exercise. 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. Seldom are they the sign of a problem. Arthroscopic repair An arthroscope is inserted into the knee to see the tear. Long ago, the menisci were felt to be vestigial structures that served no useful purpose in humans.1 Of course, we now realize that the menisci are vital structures that play a key role in the normal biomechanical function of the knee. Think before you speak. Requests for permission to reprint articles must be sent to Typically, complex tears are not treated with meniscus repair due to their complex nature. w/severe pain?

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. Arthroscopy 2010;26:13689. This often signals a tear. Submission to the Department of Health and Ageing. 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. Surgery is most likely needed to resolve your problem. Brain Res Rev 2009;60:187201. (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. Location -A tear may be located in the anterior horn, body, or posterior horn.A posterior horn tear is the most common. Diagnosis can be suspected clinically with joint line tenderness and a positive Mcmurray's test, and can be confirmed with MRI studies. A longitudinal tear is an example of this kind of tear. 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. This puts tension on a torn meniscus. In addition, focal chondral lesions occur more commonly with medial than lateral-sided injuries. The knee: a comprehensive review. Physiotherapy at two visits per week for at least 8 weeks is recommended.20 There is little evidence for strapping of meniscal injuries and this is not currently recommended. Explains when surgery is done. Know what to expect if you do not take the medicine or have the test or procedure. It has been shown the peak tibiofemoral contact pressure after a total meniscectomy is equal to a posterior medial meniscal root tear. 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.

The knee meniscus: structure-function, pathophysiology, current repair techniques, and prospects for regeneration. Tears to the medial meniscal root change the biomechanics and kinematics of the knee, which cause early degeneration of the joint. Orthop Clin North Am. 5 Horizontal tears, the most common meniscal tear pattern, lie parallel to the tibial plateau and separate the meniscus into upper and lower parts (4a,4b).

Characterization of the red zone of knee meniscus: MR imaging and histologic correlation. The skilled interpreter of MR of the knee must do more than simply identify the presence of a meniscal tear. De Carlo M, Armstrong B. Fat-suppressed proton density-weighted (4a) sagittal and (4b) coronal images reveal a horizontal tear of the posterior horn of the medial meniscus (arrows), extending to the tibial surface.

Clinical: Most trauma to knee joint is caused by a lateral blow at knee level when foot is planted when knee is slightly flexed. Henning C, Lynch M, Clark J. Vascularity for healing of meniscus repairs. Peripheral meniscal tears are among the most common causes of meniscal pathology, particularly occurring in conjunction with anterior cruciate ligament (ACL) injury or deficiency. This is because this area has rich blood supply and blood cells can regenerate meniscus tissue or help it heal after surgical repair. The typical meniscal pain profile comprises well localised joint-line pain (with medial pain generally being indicative of a medial tear and vice-versa). Your doctor will bend your knee, then straighten and rotate it. type 3, vertical longitudinal bucket-handle tears; type 4, complex oblique tears; and type 5, bone avulsion fractures of the root attachments.

If your symptoms do not persist and you have no locking or swelling of the knee, your doctor may recommend nonsurgical treatment. Arthroscopic treatment is typically required for adequate symptom relief in patients with displaced meniscal flap tears. These are the horns. Meniscal repair is a more difficult surgical technique and requires a motivated, diligent patient in order to be successful. The best known displaced tear that is amenable to repair is the bucket-handle tear. In fact, the tear will most likely get bigger leading to additional damage if not taken care of soon. and oblique tear . Unhappy Triad: Stress is put on medial side of the knee which potentially tears three related structures The menisci act as cushions between your shin bone (tibia) and your thigh bone (femur).
