The first group received a ropivacaine continuous femoral nerve block and oral hydrocodone (block group). The second group received an intra-articular bupivacaine\/morphine injection and oral oxycodone (injection group). Patients in both groups could receive intramuscular injection of hydromorphone for breakthrough pain; most patients in the block group also received bolus doses of ropivacaine through the femoral catheter. Subjects rated their worst, average, and current pain levels using a visual analog scale and category-ratio scale the morning after surgery. Postoperative narcotic pain medication use was converted to morphine-equivalent doses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Postoperative pain ratings did not differ between the treatment groups.
