Title: | Complex regional pain syndrome of the knee after conventional radiofrequency ablation of the genicular nerves treated successfully with dorsal root ganglion stimulation: A case report | Authors: | BELBA, Amy Vanneste, Thibaut Jerjir, Ali SMEETS, Kristof Van Buyten, Jean-Pierre BELLEMANS, Johan VAN ZUNDERT, Jan |
Issue Date: | 2022 | Publisher: | WILEY | Source: | Pain Practice, 22 (5) , p. 541 -546 | Abstract: | Background Radiofrequency (RF) treatment of the genicular nerves offers pain relief in patients suffering from chronic knee pain including persistent post-surgical knee pain (PPSP). We present the first case report of the development of complex regional pain syndrome (CRPS) in a chronic knee pain patient after an RF ablation of the genicular nerves that was successfully treated with dorsal root ganglion (DRG) stimulation. Case Presentation The patient developed increased pain, sympathetic and dysmorphic changes of the index knee 10 weeks after RF treatment for PPSP. Diagnosis of CRPS type II was made using positive clinical findings and the Budapest diagnostic tool. Laboratory workup and PET-CT were negative. The patient was refractory to usual care and she was treated successfully with dorsal ganglion root stimulation. Conclusions Complex regional pain syndrome is a possible complication of RF ablation of the genicular nerves in patients with chronic knee pain, and DRG stimulation may be a treatment option. Physicians should be aware of this complication, especially when patients have a medical history of CRPS. | Notes: | Van Zundert, J (corresponding author), Hosp Oost Limburg, Emergency Med & Multidisciplinary Pain Ctr, Dept Anesthesiol, Intens Care Med, Schiepse Bos 6, B-3600 Genk, Belgium. jan.vanzundert@zol.be |
