TJA Morphine Milligram Equivalents for Each Postoperative Period. Average daily morphine milligram equivalents (MMEs) for Total Joint Arthroplasty (TJA) at each postoperative period. Medication classes are represented as A no medication (green, 0 MME), B over-the-counter medication (green, 0 MME), C occasional use of short-acting narcotics (yellow, 1–30 MMEs), D consistent use of short-acting narcotics (red, 31–79 MMEs), and E long-acting narcotics (dark red, 80 + MMEs). The average daily MMEs for each medication class are displayed in the bars present at each postoperative period. The overall average for a specific postoperative period = (Sum of all daily MMEs for the specific postoperative period)/(total number of patients in same postoperative period). Statistical differences in MMEs from three weeks to three months are represented by an asterisk
