Objective: Although complex regional pain syndrome (CRPS) of the knee is comparable to CRPS of the ankle/foot at time of diagnosis, no reports are available concerning the course of knee CRPS. Therefore, this study investigated the clinical course in terms of the symptoms and signs, health-related quality of life (HR-QoL), and work status of patients diagnosed with CRPS of the knee.
Design: Observational, descriptive study.
Background And Objectives: Patients with complex regional pain syndrome (CRPS) confined to the knee are often therapy resistant. Neurostimulation is an accepted treatment for CRPS. Although results with dorsal column (DC) stimulation in patients with CRPS confined to the knee are often disappointing, the availability of dorsal root ganglion (DRG) stimulation may provide new opportunities for this complaint.

Setting: A retrospective study.
Subjects: Patients with CRPS of the knee and patients with CRPS of the ankle/foot.
Objectives: To report on the efficacy of dorsal root ganglion stimulation in a patient with complex regional pain syndrome (CRPS) type I of the knee.
Materials And Methods: A 48-year-old woman with CRPS type I of the right knee, diagnosed according to the Budapest criteria set, received DRG stimulation for intractable CRPS type I of the knee.
Results: After a successful trial period with three DRG stimulation leads on spinal levels L2, L3, and L4 (covering 90% of the painful area of her knee), a definitive pulse generator was implanted.
