The ACL receives nerve fibers from the posterior articular branches of the tibial nerve. These fibers penetrate the posterior joint capsule and run along with the synovial and periligamentous vessels surrounding the ligament to reach as far anterior to the infrapatellar fat pad.

I just wanted to take a moment to clarify the idea of “outdated research”. This is not a thing. A study does not become “untrue” due to the passing of time. INTERPRETATIONS of those data become outdated.
