Ouch on the Inside: Understanding MCL Sprains of the Knee breaks down one of the most common knee injuries seen in sports and everyday activity. In this episode, we explain what the medial collateral ligament (MCL) does, how it helps stabilize the inner side of the knee, and why it is often injured when the knee is hit from the outside or twisted awkwardly. We walk through common symptoms such as pain and swelling along the inside of the knee, how doctors diagnose MCL injuries using physical exam and imaging, and why X-rays and MRI may be helpful in some cases. The episode also covers treatment options, including bracing, rest, physical therapy, and when surgery may be considered for more severe or combined ligament injuries.
