Total knee arthroplasty is one of the most common elective procedures performed in the United States. Regional anesthesia modalities are a key component of multimodal analgesia for this surgery and consists of both single-injection and/or continuous peripheral nerve blocks. Two novel modalities for prolonged-analgesia include percutaneous cryoneurolysis and peripheral neuromodulation. Cryoneurolysis refers to the process of reversibly destroying the myelin sheath of peripheral nerves with extremely cold temperatures. Peripheral neuromodulation refers to the utilization of electricity to target nerves to induce analgesia. This article reviews these analgesic modalities, including auricular neuromodulation, and their application for knee arthroplasty.

Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
