Percutaneous periarticular multi-drug injection at one day after total knee arthroplasty as a component of multimodal pain management: A randomized control trial

Although intraoperative periarticular multi-drug injection has been used for postoperative pain control after total knee arthroplasty (TKA), the injection has the inherent shortcoming of limited acting time. This randomized controlled trial was performed to assess whether adding percutaneous periarticular multi-drug injection at the day following TKA would improve the postoperative pain relief. |
