MASI Clinic on Instagram: "A PCL tear changes how the knee moves. When the tibia shifts backward, it increases shear forces across the cartilage and meniscus — especially when you straighten or hyperextend the knee. That’s why people feel popping, catching, or instability. At MASI Clinic, we don’t just look at the ligament. We look at how the entire knee is being stressed — so we can protect the cartilage, preserve the meniscus, and guide the right path forward."
