CommentTechnical Considerations for Genicular Nerve Radiofrequency Ablation: Optimizing Outcomes.
Genicular nerve radiofrequency ablation has emerged as a treatment option for patients with painful knee osteoarthritis who have failed conservative management but who may not qualify or wish to avoid a surgical procedure. Radiofrequency ablation techniques targeting the genicular nerves have evolved as our understanding of the anatomy of the anterior knee joint capsule has become more defined. The article aims to review the basic anatomy of the anterior knee joint and both the traditional and revised approaches to nerve ablation.

CommentAvoid suboptimal perioperative analgesia during major surgery by enhancing thoracic epidural catheter placement and hemodynamic performance.
Thoracic epidural analgesia (TEA) is an established gold standard for postoperative pain control especially following laparotomy and thoracotomy. The safety and efficacy of TEA is well known when the attention to patient selection is upheld. Recently, the use of fascial plane blocks (FPBs) has evolved as an alternative to TEA most likely because these blocks avoid problems such as neurological comorbidity, coagulation disorders, epidural catheter failure and hypotension due to sympathetic denervation. ⋯ Also, the true efficacy of FPBs is questioned. Thus, should we prioritize less efficient analgesic regimens with FPBs when preventive treatment strategies for epidural catheter failure and hypotension exist for TEA? It is time to promote and underscore the benefits of TEA provided to patients undergoing major open surgical procedures. In our mind, FPBs and landmark-guided techniques should be limited to less extensive surgery and when either neuraxial blockade is contraindicated or resources for optimal epidural catheter placement and maintenance are not available.
