Experimental
Placebo Comparator
Periarticular Injection + Adductor Canal Block (Local Anesthestic)
Periarticular Injection + Adductor Canal Block (Normal Saline)
The experimental arm with receive both the periarticular injection and the adductor canal block. The periarticular injection will be performed by the surgeon and will consist of 100 mL of injectate being distributed in the following manner: 30 mL to the posterior capsule, 10 mL to the medial collateral ligament, 10mL to the lateral collateral ligament (ensuring not to infiltrate common peroneal nerve), 20mL to the quadriceps and anterior capsule, and 30 mL to the subcutaneous tissue. The periarticular injection will consist of 250 mg of ropivacaine, 30 mg of ketorolac, and 0.5 mg of epinephrine. The adductor canal block will be completed by the anesthesiologist after spinal anesthesia has been initiated, but before the surgery commences. The block will be completed using an aseptic technique under dynamic, in-plane US guidance. 20 mL of injectate consisting of 100mg of ropivicaine and 50 mcg of epinephrine will be injected around the hyperechoic saphenous nerve.
The control arm with receive a periarticular injection and a sham adductor canal block. The periarticular injection will be carried out in the same manner as described for the experimental group. The technical aspects of the sham adductor canal block will be the same as for the experimental arm; however, the injectate will consist of 20 mL of normal saline.
