Biologics injections, such as platelet-rich plasma (PRP), are currently being studied and may show promise in the future for the treatment of meniscus tears. The best known displaced tear that is amenable to repair is the bucket-handle tear. 12 McGinty JB, Burkhart SS, Jackson RW, et al. They act as shock absorbers and stabilize the knee. This extrusion should disappear without stress. 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. Treatment for a meniscus tear will depend on its size, what kind it is, and where it's located within the cartilage. The medial meniscus is an important secondary stabilizer of the knee. Biomechanical studies have demonstrated that repair of medial meniscus posterior root tears leads to improved contact mechanics. .

With a bucket handle tear, a tear forms in the center of your meniscus. 1. The younger population, particularly males with knee instability, is most commonly affected by this type of tear [56]. Fat-suppressed coronal images demonstrate before and after images following repair of a bucket handle tear. In cases where surgery is required, this time frame increases to somewhere around three to four months. The meniscus root attachment aids meniscal function by securing the meniscus in place and allowing for optimal shock-absorbi If the tear is associated with arthritis it will typically improve over time as the arthritis is treated. Repair of such lesions can result in dramatic clinical as well as MR imaging results (17a,17b). 2010.

There are numerous treatments for meniscus tears, but treatment generally begins conservatively depending on the location, type, and size of the tear. Conservative management is important in all patients with acute rest, intensive rehabilitation with physiotherapy and modification of activity. 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. In addition to categorizing meniscal tears based on morphology, care should be taken to describe the exact location of meniscal tears. Aging is also a risk factor due to general wear and tear of the knees.

I have an oblique horizontal tear posterior horn medial meniscus, what does that mean? Although some reports have described successful repair of the avascular portion of the meniscus,11 it is generally accepted that meniscal repair is more likely to be successful if it involves or at least communicates with the meniscal red zone, lying within three to four millimeters of the capsular rim.12 A basic principle of meniscal repair is to rasp the tear edges and the parameniscal synovium above and below the meniscus, which is thought to enhance the vascular healing process. The clinician applies axial pressure to the foot and rotates the tibia internally and externally. This part of the tibia is also known as the tibial plateau.
