A lateral collateral ligament (LCL) tear is a knee injury that causes pain, swelling and bruising. Your LCL is a band of tissue located on the outside of your knee (the side that faces away from your body). This tissue connects your lower leg bones to your thigh bone. It stops your knee from bending outward abnormally.

2022年8月12日 · What Is an LCL (Lateral Collateral Ligament) Injury? An LCL injury (a torn LCL or a LCL tear) is a strain or tear to the lateral collateral ligament...

The LCL stabilizes the lateral side of the knee joint, mainly in varus stress and posterolateral rotation of the tibia relative to the femur. The LCL acts as a secondary stabilizer to anterior and posterior tibial translation when the cruciate ligaments are torn.

Although less frequent than other ligament injuries, an injury to the lateral collateral ligament (LCL) of the knee is most commonly seen after a high-energy blow to the anteromedial knee, combining hyperextension and extreme varus force. The LCL can also be injured with a non-contact varus stress or non contact hyperextension.

2023年9月14日 · An LCL sprain or lateral knee ligament sprain is a tear to the ligament on the outside of the knee. It most commonly occurs following a direct blow to the inside of the knee. However, it can also develop gradually through overuse.

2023年11月22日 · LCL tears are usually caused by a strong force from the inner front of the knee, forcing the knee into extreme extension and causing it to gap on the outside. Examples are a rugby player falling on their knee or a tennis player pivoting quickly and forcefully.

6 天之前 · The Lateral Collateral Ligament (LCL) is a key stabilizer of the knee joint, located on the outer side. It connects the femur (thigh bone) to the fibula (the smaller bone of the lower leg) and provides stability by preventing excessive side-to-side movement.

2021年8月11日 · Injuries to the LCL, such as sprains and tears, can cause symptoms such as weakness in the knee, pain, and swelling. Injuries are typically more common in athletes who participate in contact...

2019年3月8日 · Ligaments are thick, strong bands of tissue that connect bone to bone. The LCL runs along the outside of the knee joint, from the outside of the bottom of the thighbone (femur) to the top of the...

2024年2月11日 · Lateral Collateral Ligament (LCL) injuries of the knee typically occur due to a sudden varus force to the knee and often present in combination with other ipsilateral ligamentous knee injuries (ie. PLC, ACL). Diagnosis can be suspected with increased varus laxity on physical exam but require MRI for confirmation.
