Summary
The purpose of this study is to determine if an additional injection of local anesthetic
immediately prior to removal of the local anesthetic infiltration catheter on postoperative
day one is effective in increasing pain reduction, patient satisfaction or outcome measures
following total knee replacement (TKR). It is hypothesized that an additional injection of
30ml of .5% bupivacaine solution immediately before infiltration catheter removal will
provide pain reduction, patient satisfaction and outcome measures equal or superior to
catheter removal with no additional injection.
Patients who are undergoing unilateral total knee replacement (TKR) and choose to participate
will be randomly assigned to a treatment group.Patients in group one (treatment group) will
receive a 30ml dose of .5% bupivacaine solution injected into the local anesthetic
infiltration catheter immediately prior to its removal on postoperative day one. Patients in
group two (control group) will receive no additional medication during local anesthetic
infiltration catheter removal.
