Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patient with atraumatic knee pain without a large knee effusion on x-ray will be randomized to receive either a genicular nerve block (GNB) or standard of care in the emergency department.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Genicular Nerve Block

This arm of patients (17 total) will receive the genicular nerve block for their knee pain.

Group Type EXPERIMENTAL

Genicular nerve block with bupivacaine and corticosteroids

Intervention Type PROCEDURE

genicular nerve block with ideal body-weight dosing of bupivacaine 0.5% with 4 mg dexamethasone

Standard of Care

This arm of patients (17 total) will receive standard of care analgesia for their knee pain

Group Type ACTIVE_COMPARATOR

Standard of Care

Intervention Type OTHER

This involves standard of care pain relief for patients who do not receive the genicular nerve block for knee pain, such as acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and opioids.
