Hello viewers, welcome to my channel. I am Dr. Abhijeet and in today's video, we will talk about MCL i.e. Medial Collateral Ligament Injury. This injury can be in the form of sprain or tear. So, the MCL is in the inner part of our knee. The upper part of this is attached to the femur bone and the lower part is attached to the tibia bone. The MCL stabilizes our knee from inner side. In addition to this, along with ACL, PCL and LCL, it improves the overall stability of the knee. So, MCL injury is commonly seen in sports like football, basketball and tennis. In addition to this, MCL injury can also occur in the common population. So, the injury of MCL is mostly seen in the form of stretch or sprain and the complete tear is seen less. Let's talk about the injury mechanism of Medial Collateral Ligament. So, when the knee is bent and at the same time, force is applied to the inside of the knee, which we call Valgus Stress Force. Due to this, the Medial Collateral Ligament is stretched and sprain occurs which injures the MCL. Let's talk about the grades of injury. So, the injury of MCL has three grades. Grade 1 is Mild Injury, Grade 2 is Moderate Injury and Grade 3 is Complete Tear. So, viewers, let's understand in detail about the symptoms Grade 1. So, viewers, in Grade 1injury, when you touch the inner part of the knee, you feel pain. There is no swelling and at the same time, the knee remains stable because there is no laxity in the ligament it is a mild injury. Similarly, in Grade 2 injury , when you touch the inner part of the knee, you feel pain. There is swelling and when we perform Valgus Stress Test on it, i.e. when we apply the force on the inner part of the knee, then the laxity is less than 5 mm. So, viewers, now let's talk about Grade 3 injury The Grade 3 MCL injury occurs mostly along with with the Anterior Cruciate Ligament. There is swelling and knee doesn't fully straighten and when the knee opens from the inside, then the outer meniscus, i.e. the lateral meniscus gets compressed and lateral meniscus also gets injured. So, viewers, these were the three grades of MCL injury. After this, we will move ahead in the video and see how we have to treat the injury of Medial Collateral Ligament.
