Despite the addition of selective regional blockade by the anesthesia team including femoral and saphenous nerve blocks, a portion of patients are still experiencing post-operative knee pain within the first few hours to days after the procedure. Pain may be a result of the femoral tunnel drilling which theoretically may be relieved by a posterior capsular injection. Eliminating this painful period will improve the patient's subjective experience undergoing surgery, and may also allow for earlier range of motion and participation in rehabilitation strengthening exercises performed by the patient in the peri-operative period.
