Summary

Major surgery involving the knee is often associated with severe postoperative pain. Postoperative pain control remains a significant contributor to delayed recovery and length of hospital stay. Approaches to minimize postoperative pain after surgery are a matter of major concern due to the need for early mobilization, a crucial factor in good postoperative rehabilitation. Femoral nerve blocks by either continuous infusion or single injection of anesthetics provide an effective method for analgesia while minimizing the need for systemic opioid therapy, reducing the opioid induced side effects, and facilitating early ambulation. Administration of fentanyl has shown to be a highly effective method to control pain after Total Knee Replacement (TKR). The investigators hypothesize that fentanyl infusions will result in greater post-operative strength in the operative knee.

Conditions

  • Total Knee Replacement
  • Primary Knee Arthroplasty

Interventions

DRUG

Fentanyl

Fentanyl 3 µg/ml continuously infused for a 24 hour period at a basal rate of 10ml/hour starting from the time the patient entered the post anesthesia care unit (PACU)through a femoral nerve sheath catheter.

DRUG

Ropivacaine

Ropivacaine 0.1% delivered through a femoral nerve sheath catheter continuously for a 24 hour period at a basal rate of 10ml/hour starting from the time the patient entered the post anesthesia care unit (PACU).

DRUG

Fentanyl

0.9% normal saline delivered through a femoral nerve sheath catheter in addition to a continuous intravenous infusion of fentanyl 3 µg/ml via a PCA pump for a 24 hour period at a basal rate of 10ml/hour starting from the time the patient entered the post anesthesia care unit (PACU).
