<br />
The '''fibular collateral ligament''' (FCL), also known as the '''lateral collateral ligament''' (LCL), is a key ligament located on the outer side of the [[knee joint]]. It is one of the four major ligaments that contribute to the stability of the knee.<br />
<br />
==Anatomy==<br />
The fibular collateral ligament is a strong, cord-like structure that extends from the lateral epicondyle of the [[femur]] to the head of the [[fibula]]. It is situated on the lateral aspect of the knee, outside the [[joint capsule]], and is separated from the [[lateral meniscus]] by a small fat pad.<br />
<br />
==Function==<br />
The primary function of the fibular collateral ligament is to provide stability to the knee by resisting varus forces, which are forces that push the knee outward. It works in conjunction with other structures, such as the [[anterior cruciate ligament]] (ACL), [[posterior cruciate ligament]] (PCL), and the [[medial collateral ligament]] (MCL), to maintain the overall stability of the knee joint.<br />
<br />
==Injury==<br />
Injuries to the fibular collateral ligament are less common compared to injuries to the [[medial collateral ligament]] or the [[anterior cruciate ligament]]. However, they can occur due to direct trauma to the inner side of the knee or due to excessive varus stress. Symptoms of an FCL injury may include pain, swelling, and instability of the knee.<br />
<br />
==Diagnosis==<br />
Diagnosis of an FCL injury typically involves a physical examination, where specific tests such as the varus stress test are performed. Imaging studies, including [[X-ray]] and [[magnetic resonance imaging]] (MRI), may also be used to confirm the diagnosis and assess the extent of the injury.<br />
<br />
==Treatment==<br />
Treatment for fibular collateral ligament injuries depends on the severity of the injury. Mild injuries may be managed with rest, ice, compression, and elevation (RICE), along with physical therapy. Severe injuries, particularly those involving other structures of the knee, may require surgical intervention to repair or reconstruct the ligament.<br />
