Knee Capsular Corner Injury

  • A capsular corner injury of the knee is not often talked about but is often present for individuals who are dealing with instability of the knee and are having a more difficult time returning to activity. We’re talking primarily about posterolateral and little about posteromedial corner injuries of the knee.

Brief overview of the episode:

Knee capsular corner injuries are not commonly referred to but they result in long-term instability of knee. The current incidence has not been widely reported but at least currently appears to not be that common. The incidence goes up depending on mechanism.

A direct blow into a posterolateral direction, hyperextension or other high-energy trauma is the most likely mechanism to injury the posterolateral corner of the knee capsule. Symptoms beyond instability include tendernesss, swelling, bruising, standing varus and varus or hyperextension varus during gait.

In most cases a corner injury of the knee does not occur in isolation. They are most common with posterior cruciate and anterior cruciate ligament ruptures.

  • In this episode: Lateral collateral ligament (LCL) injuries are rare. It is a round thick ligament on the outside of the knee. There is almost no data surrounding injuries to it in isolation. Even when a horrific injury like a knee dislocation occurs the LCL is often not completely ruptured.

Brief overview of the episode:

            Lateral collateral ligament (LCL) is a thick round ligament on the outside of the knee. It is comparable in size to a pencil or your pinky finger. It is the least injured ligament of the knee. LCL injuries are rare occurring so infrequently that there is very little data available regarding their rate of occurrence.

            LCL injuries occur as a result of high velocity force applied to the inside of the keep causing a varus (outward) stress to the lateral knee. Essentially this causes the two bones, tibia and femur, to move away from each other damaging the ligament.

            In most cases where the LCL is damaged there are additional injuries. These could include, meniscus, other ligaments of the knee, fracture, blood vessels and the posterior lateral corner of the joint capsule. In most cases these other injuries will be more limiting and will more often then not dictate the treatment that follows.
