Perthes' disease is a rare paediatric condition involving idiopathic avascular necrosis of the femoral head, leading to degenerative hip joint disease. While joint replacement surgery is considered as the definitive surgical choice of managing degenerative hip disease, alternative methods of pain relief are available, especially for young patients, to defer joint replacement to a later date. One method of reducing pain for 18-24 months is cooled radiofrequency ablation (CRFA). CRFA has been gaining recognition as an effective treatment option for chronic musculoskeletal-related pain in multiple joints. This is the first case report describing the successful use of CRFA in the non-surgical management of Perthes' disease-related osteoarthritic hip pain in a man in his 40s. CRFA treatment led to a reported subjective improvement in pain of 60%-70%, with a documented objective improvement in the Oxford Hip Score from 18 to 40 within 6 weeks of the CRFA procedure.
