Everything you never wanted to know about PCL:

Posterior cruciate ligament (PCL) injuries account for up to 23% of all knee ligament injuries in the general population and are most commonly seen as a result of motor vehicle accidents and sports-related injuries. The anatomic and biomechanical roles of the PCL have been less investigated and are less well understood than those of the anterior cruciate ligament (ACL). Not surprisingly, the clinical outcomes of PCL injuries treated either conservatively or by surgery are poorer than those for the ACL. The appropriate surgical treatment of PCL injuries is controversial.

"Interstitial", in the medicaal sense, means:

situated within but not restricted to or characteristic of a particular organ or tissue —used especially of fibrous tissue

I think the reason you didn’t get much response is that it took very little research to get the answer. I am not a doctor in real life, I simply copied your first question, verbatim, into Google. Not sure what the second question means…

Indeed, and HERE is another, but much more accessible, description of the PCL and injury to it (including definitions of grade 1, 2, 3, etc).
