- A 59-year- old woman has been told by her orthopedist that the preferred treatment for her debilitating pain in both knees is knee replacement surgery. She agrees to have the surgery in one month when she will have time for rehabilitation. In the interim, the physician prescribes a medication for pain relief and to reduce inflammation. The woman is otherwise healthy, takes no medication, and has no known drug allergies. The physician decides on a nonsteroidal anti- inflammatory drug that has a high affinity for cyclooxygenase-2 (COX-2) and no affinity for COX-1. Compared to other NSAIDs, this drug is less likely to cause:

Physical examination reveals relatively normal lumbar range of motion, normal straight leg raise, and reveals normal muscle tone, strength and sensation throughout both lower extremities.
