Randomized Controlled Trial Comparative Study
A randomized comparative evaluation of local infiltration analgesia, extended nerve blocks, and conventional analgesia in pain management after total knee arthroplasty.
The aim of this study was to analyze the postoperative effects of extended nerve blocks and local infiltration analgesia (LIA) on postoperative pain control, muscle weakness, and blood loss after total knee arthroplasty (TKA). ⋯ This study demonstrates that LIA technique offers a fast and safe treatment option for pain relief after TKA. No clinically relevant muscle weakness was observed among groups according to field block applications. Significant advantages were also achieved in blood loss.
