In a double-blinded trial, 48 patients scheduled for total knee arthroplasty were randomly assigned to receive either a high volume/low concentration solution of ropivacaine (20 ml, 0.5{\%}) or a low volume/high concentration solution of ropivacaine (10 ml, 1{\%}), 6 and 24 h postoperatively through an intracapsular catheter.

No reduction in pain scores was observed with ropivacaine injection 6 h postoperatively.
