Posterior capsule injection of local anesthetic for post-operative pain control after ACL reconstruction: a prospective, randomized trial

Purpose Alternative modalities to optimize pain control after anterior cruciate ligament reconstruction (ACLR) are continually being explored. The purpose of this study was to compare femoral nerve block (FNB) only vs FNB with posterior capsule injection (PCI) of the knee for pain control in patients undergoing ACLR.
