Genicular Nerve Block After Open Reduction Internal Fixation of Tibial Plateau

The investigators are conducting this research study to find better ways of treating pain following knee surgery like the one the participant will be having. There is a standard (accepted) approach, which involves injection of numbing medication into the area around the participant surgical incision. The investigators hope to discover if providing numbing medication to a nerve that controls pain in a larger area of the knee (a nerve block), might be better at post-operative pain control. This type of nerve block is commonly used to treat other knee pains, like that associated with arthritis, after knee replacements, and after repairs of the knee ligaments; however, it is considered experimental in your case, as its effects (good or bad) are unknown in the type of knee surgery the participant are undergoing. The investigators plan is to decide at random, like the flip of a coin, whether to give numbing medication (0.25% bupivacaine) around the incision like the investigators normally would or give it instead to block the pain sensors around the knee. The participant would get medication either at the incision (shin) or the knee, depending on which arm the participant are in (research). The participant will also be given pain medication pills by your surgeon as part of the participant normal postoperative care (not research).
