Randomized Controlled Trial Comparative Study
Local anesthetics after total knee arthroplasty: intraarticular or extraarticular administration? A randomized, double-blind, placebo-controlled study.
High-volume local infiltration analgesia with additional intraarticular and wound administration of local anesthetic has been shown to be effective after knee replacement, but the optimum site of administration of the local anesthetic (i.e. intraarticular or extraarticular) has not been evaluated. ⋯ The optimal site of administration of local anesthetic in total knee arthroplasty cannot be determined from the present study. However, the insignificant analgesic effect from additional administration of extraarticular local anaesthetic may have been due to the relatively low pain scores observed 24 h postoperatively, confirming the efficiency of the high-volume infiltration analgesia technique. Further studies are required to define the optimal site of administration of local anesthetic following knee replacement surgery.

Randomized Controlled Trial Comparative Study
A compression bandage improves local infiltration analgesia in total knee arthroplasty.
High-volume local infiltration analgesia has been shown to be an effective pain treatment after knee replacement, but the role of bandaging to prolong analgesia has not been evaluated. ⋯ A compression bandage is recommended to improve analgesia after high-volume local infiltration analgesia in total knee arthroplasty.
