Study Summary

The purpose of this study is to evaluate the effects of a peripheral nerve block technique (adductor canal block and the combination of adductor canal block and anterior femoral block) on pain scores, length of pain relief (analgesia), postoperative narcotic (opioids) requirements, and patient satisfaction after knee surgery (total knee arthroplasty).

Study Description

Patients undergo total knee arthroplasty, will receive bupivacaine as part of the regular clinical care to manage pain and improve recovery after surgery.

During and after the surgery, patients most likely need narcotics (opioids) for pain that can cause side effects such as nausea, vomiting, drowsiness and constipation. This can delay recovery.

We would like to determine if the combination of adductor canal block and anterior femoral block will provide better analgesic and pain control and reduce the use of narcotic painkiller medications (analgesics) after surgery as compared to adductor canal block alone.

The adductor canal block and/or anterior femoral block have been demonstrated to be safe and effective patient care. The use of one method versus the other may vary at different institutions.

Normally, anesthesiologist would choose which technique to use during surgery. The research part is that the technique that will be performed will be decided by randomization, this means that will be assigned by chance to one of two treatment groups:

  1. adductor canal block, or

  2. adductor canal block and anterior femoral block

Patients will have an equal chance of being placed in one of the groups. These methods are frequently utilized as part of standard anesthetic care in patients undergoing total knee arthroplasty at our institution.

We will evaluate whether or not the group of patients that receive the nerve block of the combination of adductor canal block and anterior femoral block experience a prolonged postoperative pain relief and less narcotic use comparing with the group receiving adductor canal block.
