Anterior Femoral and Adductor Canal Nerve Blocks in Peds Knees
What this study is about
The goal of this pilot clinical trial is to compare anterior femoral cutaneous nerve block (AFCN) to adductor canal block ACB) for pediatric patients undergoing either anterior cruciate ligament (ACL) or medial patellofemoral ligament (MPFL). The aims of this trial are: * To measure postoperative functional outcomes in patients who received AFCNB vs. ACB.
View original scientific description
The goal of this pilot clinical trial is to compare anterior femoral cutaneous nerve block (AFCN) to adductor canal block ACB) for pediatric patients undergoing either anterior cruciate ligament (ACL) or medial patellofemoral ligament (MPFL). The aims of this trial are: * To measure postoperative functional outcomes in patients who received AFCNB vs. ACB. * To calculate postoperative opioid requirements in pediatric knee surgeries that received AFCNB vs. ACB. * To calculate pain intensity levels at rest and with ambulation in patients who received AFCNB vs. ACB. * To quantify sensory deficits in patients who received AFCNB vs. ACB. * To assess patient-reported outcome measures (e.g., pain expectation scale, pain management satisfaction, PROMIS Pediatric Short Form v1.0 - Physical Activity, PROMIS Scale v1.2 - Global Health) in patients 8-18 years of age who received AFCNB vs. ACB. Subjects undergoing ACL procedures will be compared between those who received the adductor canal block to those who received the anterior femoral cutaneous nerve block. The researchers will also compare individuals who underwent MPFL procedures and received an anterior femoral cutaneous nerve block with those who received the adductor canal block. Participants will: * Be randomized to receive either the AFCNB or ACB in addition to standard of care analgesia. * Maintain a patient diary to document daily pain meds/pain scores * Complete follow up surveys/questionnaires via telephone and during their office visits with surgeons.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
