Q. A 61-year-old woman has been admitted for preoperative evaluations for a bilateral total hip replacement. She has rheumatoid arthritis and an unknown history of heart disease. She receives methotrexate weekly (for one year), daily low-dose aspirin (for ten years), daily alendronate (for two years), daily folic acid, and monthly vitamin D. She reports no abnormal bleeding tendency. She is an alert and cooperative lady. Her BMI is 31.2 kg/m2. The vital signs are normal. She has bilateral hip flexion contracture with painful and limited hip motions on physical examination. Both hands’ metacarpophalangeal and proximal interphalangeal joints of the 2nd-5th fingers are slightly swollen and painful. The rest of the physical examination is not remarkable. What is the best decision for her medications before surgery?
