The medial meniscus transmits approximately 50% of the total joint load of the knee medial compartment, thus protecting the articular cartilage from excessive force. The anterior horn of the medial meniscus demonstrates half of the normal anatomic 'bow-tie configuration'. Larger, unstable tears of this type often cause mechanical symptoms, however, and therefore warrant operative treatment, usually via partial meniscectomy.

Oblique Meniscomeniscal Ligament - Radsource Prospective evaluation of allograft meniscus transplantation: a minimum 2-year follow-up. 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.

They are most frequently seen at the posterior horn of the medial meniscus. can he still play tennis with this injury? Metcalf MH, Barrett GR. Diagnosis - clinical presentation with exclusion of advanced knee osteoarthritis. The treatment of these type of tears can be either arthroscopy (surgery through a tiny hole in knee) or conservative. This pattern of tear requires resection to prevent propagation of the tear as the flap gets caught within the joint during flexion. It seems that in the above knee, the biology of the medial compartment has gone off the ski slope in a degenerative fashion and reversing that ski slope fall seems to be unproven at this time, particularly in the patient with low functional demands, who is older than 40 years and who has a BMI greater than 30. Medial and lateral menisci are crescent-shaped fibrocartilage structures that provide joint congruity, stabilization and lubrication and act as shock absorbers for joint preservation. Meniscal root tears, less common than meniscal body tears and frequently unrecognized, are a subset of meniscal injuries that often result in significant knee joint disorders. 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. An awkward twist when getting up from a chair may be enough to cause a tear in an aging meniscus. Magnetic resonance imaging is first line for investigating potential meniscal lesions, but should not replace thorough clinical history and examination.

Before your visit, write down questions you want answered. Horizontal tears can be sewn together rather than removing the damaged portion. Because other knee injuries can cause similar symptoms, your doctor may order imaging tests to help confirm the diagnosis. They will also consider the type, size, and location of the injury. These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses. Arthroscopic meniscus repairs typically takes about 40 minutes. Clin Sports Med 2010;29:81106. This opening pushes the inside edge of your meniscus toward the middle of your knee.
