PCL tear: An isolated PCL tear depending on degree can allow a person to function fairly well. A high grade or complete PCL may hasten patello-femoral arthritis. Often time a PCL tear is associated with posterolateral (pl) or posteromedial (pm) instability which warrants PCL reconstruction with pl or pm reconstruction.
