Pain after a total knee replacement (TKR) is usually managed with medication. Narcotics and especially patient-controlled analgesia (PCA) are used for many TKR patients.
However, a new study shows that using a particular injection may be a better choice. Researchers report the results of injecting a cocktail of drugs into the knee during the operation. The cocktail is a mixture of drugs. It includes a numbing agent like Novocain, antibiotics, morphine, and steroids (anti-inflammatory).
