Is Pain After TKA Better with Periarticular Injection or Intrathecal Morphine?

摘要

Intrathecal morphine or periarticular multimodal drug injection are both commonly used and both appear to provide better pain control than placebo, but it is unclear whether one or the other provides better pain control.
