The lateral collateral ligament (LCL, long external lateral ligament or fibular collateral ligament) is an extrinsic ligament of the knee located on the lateral side of the knee. [ 1 ] [ verification needed ] [ 2 ] Its superior attachment is at the lateral epicondyle of the femur (superoposterior to the popliteal groove); its inferior ...
[2] [13] More than a 2.7 mm increase between sides indicates a fibular collateral ligament tear, while greater than 4.0 mm indicates with a grade III posterolateral knee injury. [20] Posterior stress radiographs taken with the patient kneeling show the amount of posterior tibial translation in both knees and are helpful to diagnose PCL ...
The coronary ligaments connect the peripheral meniscal rim loosely to the tibia. Although the lateral collateral ligament (LCL) passes in close proximity, the lateral meniscus has no attachment to this structure. [11] The joint capsule attaches to the entire periphery of each meniscus but adheres more firmly to the medial meniscus.
The unhappy triad, also known as a blown knee among other names, is an injury to the anterior cruciate ligament, medial collateral ligament, and meniscus.Analysis during the 1990s indicated that this 'classic' O'Donoghue triad is actually an unusual clinical entity among athletes with knee injuries.
A tear in the meniscus may cause a pedunculated tag of the meniscus which may become jammed between the joint surfaces. To perform the test, the knee is held by one hand, which is placed along the joint line, and flexed to complete flexion while the foot is held by the sole (of the foot) with the other hand.
Grade 2: Many of the ligament fibers are torn, and pain and swelling is moderate. The functionality of the joint is compromised. Grade 3: The soft tissue is completely torn, and functionality and strength on the joint is completely compromised. In most cases, surgery is needed to repair the damage.
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
The most important factors of knee stability include: [citation needed] Ligaments of the knee: The knee joint is stabilized by four main ligaments: Anterior cruciate ligament (ACL). The ACL has an important role in stabilization of knee extension movement by preventing the knee from hyperextending. Posterior cruciate ligament (PCL)
