A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci. When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae .
A bucket-handle tear of the knee is a specific type of meniscal injury characterized by a longitudinal tear of the medial or lateral meniscus, where a displaced inner fragment resembles the appearance of a "bucket handle". [1]
A torn meniscus is commonly referred to as torn cartilage in the knee. Menisci tear in different ways and are noted by how they look, as well as where the tear occurs in the meniscus. Two types of tears include minor, which includes stiffness and swelling within two to three days but usually goes away in two to three weeks.
In adults, Baker's cysts usually arise from almost any form of knee arthritis (e.g., rheumatoid arthritis) or cartilage (particularly a meniscus) tear. Baker's cysts in children do not point to underlying joint disease. Baker's cysts arise between the tendons of the medial head of the gastrocnemius and the semimembranosus muscles.
MRI is perhaps the most used technique for diagnosing the state of the ACL, but it is not always the most reliable technique as the ACL can be obscured by blood that fills the joint after an injury. [34] MRI is particularly useful in cases of partial tear of the ACL. The anteromedial band is most commonly injured compared to the posterolateral ...
The procedures are more commonly performed to treat meniscus injury and to perform anterior cruciate ligament reconstruction. [3] While knee arthroscopy is commonly used for partial meniscectomy (trimming a torn meniscus) on middle aged to older adults with knee pain, the claimed positive results seem to lack scientific evidence. [4]
Anterior meniscofemoral ligament is found in 11.8% of the subjects during MRI scan of the knee. [2] It may be confused for the posterior cruciate ligament during arthroscopy. In this situation, a tug on the ligament while observing for motion of the lateral meniscus can be used to tell the two apart. [citation needed]
Structures found in the posterolateral corner include the tibia, fibula, lateral femur, iliotibial band (IT band), the long and short heads of the biceps femoris tendon, the fibular (lateral) collateral ligament (FCL), the popliteus tendon, the popliteofibular ligament, the lateral gastrocnemius tendon, and the fabellofibular ligament.
