About this study
Official title: Effectiveness of Continuous Femoral Nerve Block Versus Single Shot Femoral Nerve Block for Pain Control After Anterior Cruciate Ligament Reconstruction With Patellar Tendon Graft or Allograft
Both single shot femoral nerve block and continuous femoral nerve block with catheter have been shown to be effective for pain control after anterior cruciate ligament reconstruction (ACLR). Continuous femoral nerve block may be the more effective of the two in reducing pain scores and opioid consumption for the first 48 hours postoperatively.
Read the detailed description
The number of ambulatory procedures has steadily increased over the last decade. Postoperative pain is the most common cause of delayed discharge and unexpected admission after ambulatory surgery. Knee surgery was identified as one of the procedures associated with the most pain at 24 hours, with a 45% or higher incidence of moderate or severe pain. Poor pain control can counteract many of the benefits of ambulatory surgery and can lead to the development of chronic pain.
Regional techniques have been shown to be effective after ACL reconstruction, allowing faster patient recovery with fewer side-effects than intravenous administration of opioids. Different regional techniques have been applied and studied after ACLR. Femoral nerve block for ACLR either as a single bolus or as a continuous infusion markedly decreases intravenous analgesic requirements and postoperative pain. To the Investigator's knowledge, no study has compared these two techniques after ACLR with patellar tendon graft or allograft.

What participants receive

BupivicaineDrug
After surgery before the patient is discharged home their femoral catheter will then be connected to the home pain pump filled with bupivacaine 0.25% solution (without epinephrine), and the infusion will be started at 6 ml/hr. gh the catheter.
placeboDrug
| Study group | Role | What they receive |
|---|---|---|
| Bupivacaine | Active comparator | All patients who give consent will undergo ultrasound guided placement of a femoral catheter with injection of 30 cc of 0.5% bupivacaine (without epinephrine)through the catheter. After surgery before the patient is discharged home their femoral catheter will then be connected to the home pain pump filled with bupivacaine 0.25% solution (without epinephrine), and the infusion will be started at 6 ml/hr. gh the catheter.

| Placebo | Placebo comparator | All patients who give consent will undergo ultrasound guided placement of a femoral catheter with injection of 30 cc of 0.5% bupivacaine (without epinephrine) through the catheter. After surgery before the patient is discharged home their femoral catheter will then be connected to the home pain pump filled with saline solution, and the infusion will be started at 6 ml/hr. gh the catheter.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain Scores Will be Collected for 48 Hours After ACL Reconstruction
Pain scores will be collected for 48 hours after ACL reconstruction with a patellar tendon graft or allograft and used to measure the effectiveness of the femoral catheter vs. single shot femoral nerve block
Measured: 48 hours after surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Both single shot femoral nerve block and continuous femoral nerve block with catheter have been shown to be effective for pain control after anterior cruciate ligament reconstruction (ACLR). Continuous femoral nerve block may be the more effective of the two in reducing pain scores and opioid consumption for the first 48 hours postoperatively.

Knee surgery was identified as one of the procedures associated with the most pain at 24 hours, with a 45% or higher incidence of moderate or severe pain. Poor pain control can counteract many of the benefits of ambulatory surgery and can lead to the development of chronic pain.

Different regional techniques have been applied and studied after ACLR. Femoral nerve block for ACLR either as a single bolus or as a continuous infusion markedly decreases intravenous analgesic requirements and postoperative pain. To the Investigator's knowledge, no study has compared these two techniques after ACLR with patellar tendon graft or allograft.
