This study showed meniscus tears occurring at a rate of 50–70% depending on how long after the ACL injury the surgery occurred. [7] Meniscal ramp lesions (tears of the medial meniscus posterior horn at the menisco-capsular junction) occur in approximately 25% of ACL-injured knees. [8]
The specific structures that can be evaluated are the popliteus tendon attachment on the femur, the popliteomensical fascicles, the coronary ligament of the posterior horn of the lateral meniscus, and the meniscofemoral and meniscotibial portions of the mid-third lateral capsular ligament. [5]
The posterior meniscofemoral ligament (also known as the ligament of Wrisberg) is a small fibrous band of the knee joint. It attaches to the posterior area of the lateral meniscus and crosses superiorly and medially behind the posterior cruciate ligament to attach to the medial condyle of the femur .
Acute injury to the medial meniscus frequently accompanies an injury to the ACL (anterior cruciate ligament) or MCL (medial collateral ligament). A person occasionally injures the medial meniscus without harming the ligaments. Healing of the medial meniscus is generally not possible unless the patient is very young, usually <15 years old.
The other ligaments, all three of which are reported with a frequency of less than 4 per cent, are the posterior transverse ligament, described as a bundle of fibers connecting the posterior horns of the menisci; and the medial and lateral oblique ligaments, both of which originate on the anterior horn of their namesake meniscus, passes between ...
If the tear causes continued pain, swelling, or knee dysfunction, then the tear can be removed or repaired surgically. The unhappy triad is a set of commonly co-occurring knee injuries which includes injury to the medial meniscus.
Each meniscus have anterior and posterior horns that meet in the intercondylar area of the tibia. [13] Medial meniscus is bigger, less curved, and thinner. Its posterior horn is thicker (14mm) than the anterior horn (6mm). [13] The lateral meniscus is smaller, more curved (nearly circular), and has more uniform thickness than medial meniscus ...
Meniscal repair: Preferred for young patients or those with tears in the vascular (red-red) zone, which has healing potential. Arthroscopic sutures are used to repair the torn meniscus. Partial meniscectomy : [ 7 ] If the tear is in a non-repairable location (white-white zone) or the meniscal tissue is extensively damaged, the displaced ...
