3 Types Of Meniscal Tears

Simplified histology in understanding the tears. The most common type of tear is a longitudinal tear often termed a bucket-handle tear whereby the central tear becomes separated from the lateral fragment.

6 Types Of Meniscus Tears And Locations

There are many types of meniscal tears but four types of tears that are more frequently encountered include.

3 types of meniscal tears. Radial tie fibres Forces. Longitudinal circumferential cylindrical fibres 2. In total 75109 688 lateral meniscal tears were repaired with fewer sutures than medial 3472 472 and bilateral meniscus injuries 2044 454.

By contrast tears of stability to the posterior lateral root tears preventing the types 3 and 5 were all acute tears Table 3. A review that evaluated the prevalence of meniscal damage in asymptomatic athletes found that 311 of the athletes had meniscal damage of which 39 were tears. Meniscal tears may be categorized into five common configurations including horizontal longitudinal radial oblique parrot-beak and complex.

Standing at 20 degrees of knee flexion on the affected limb the patient twists with knee external and internal rotation with positive test being discomfort or clicking. Flat lining against the periphery of the meniscus. Flex the knee and place a hand on medial side of knee externally rotate the leg and bring the knee into extension.

Radial tears are perpendicular to the long axis of the meniscus. In some cases the damaged tissue is repaired with stitches. In general large unstable tears root tears radial tears flap tears and bucket handle tears tend to remain bothersome whereas degenerative tears typically do not produce.

It is a tear that runs horizontally along the circumferential fibers of the meniscus. Mahmut Nedim Doral 1 Onur Bilge 2 Gazi Huri 3 Egemen Turhan 3 René Verdonk 4. The diagnosis of a meniscal cyst is important to the surgeon because it takes one operation on the outside of the knee to remove the cyst and another operation on the inside for the meniscus.

However the healing depends on where the tear is and how complex the components are. Tears located at the periphery or zone 1 are referred to as red-red RR tears tears located in the middle third or zone 2 are referred to as red-white RW tears and tears located in the inner third or zone 3 are referred to as white-white WW tears 33. Often these are a sign of early degenerative changes of the meniscus tissue.

The best diagnostic performance was found for complex tears horizontal tears showed relatively good results poor results were documented for radial tears. Sports-related meniscus injuries often occur along with other knee injuries such as anterior cruciate ligament ACL tears. Tears are noted by how they look as well as where the tear occurs in the meniscus.

Tear patterns include horizontal longitudinal radial root complex displaced and bucket-handle tears. Tears are either traumatic or degenerative. What types of meniscal tears are there.

A longitudinal tear or linear tear can occurs in the red or white zone A bucket handle tear is a vertical tear that can occur in either zone. Particularly with regard to the medial meniscus 3-Tesla MRI. However secondary indirect signs such as a parameniscal cyst meniscal extrusion or linear subchondral bone marrow edema should increase the radiologists suspicion for an underlying tear.

3 The management of traumatic tears in the setting of ligamentous injury of the knee in young patients is fairly clear cut. A horizontal tear in the meniscus is actually one of the most treatable types of meniscal tears. The Top 6 Common Types of Meniscal Tears 1.

Treatment options for meniscal tears fall into three broad categories. Meniscal repair or preservation in combination with a stable knee lead to less long-term degeneration in the knee. 5 Horizontal tears the most common meniscal tear pattern lie parallel to the tibial plateau and separate the meniscus into upper and lower parts 4a4b.

Type 5 tears increased mobility and meniscal extrusion that is often or avulsion fractures were not subject to this distinction. Meniscus within meniscus appearance 2. Occasionally meniscal tears can be difficult to detect at imaging.

Similar to how the type of meniscus tear can determine whether or not your tear is repairable The various types of meniscus tears we have might predict how much the meniscus tear will bother you. Non-operative meniscectomy or meniscal repair. For the medial meniscus where horizontal and complex tears were more prevalent 3-Tesla MRI shows a higher accuracy than for the lateral meniscus.

Both longitudinal and radial tears may appear vertical on MR images. Surprisingly athletes in non-pivoting sports were found to have a higher prevalence of meniscal tears 54 than those in pivoting sports 25. There are a number of types of meniscal tears.

Common tears include bucket handle flap and radial. Selecting the most appropriate treatment for a given patient involves both patient factors eg age co-morbidities and compliance and tear characteristics eg location of tearagereducibility of tear. Radial tears of the meniscus are the most common type of meniscus tear.
