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\u201324 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\u2019 disease-related osteoarthritic hip pain in a man in his 40s. CRFA treatment led to a reported subjective improvement in pain of 60%\u201370%, with a documented objective improvement in the Oxford Hip Score from 18 to 40 within 6 weeks of the CRFA procedure.<\/jats:p>","DOI":"10.1136\/bcr-2021-247916","type":"journal-article","created":{"date-parts":[[2022,3,17]],"date-time":"2022-03-17T13:07:20Z","timestamp":1647522440000},"page":"e247916","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Cooled radiofrequency ablation for pain related to Perthes\u2019 disease: a novel application"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7280-4719","authenticated-orcid":false,"given":"Qiao Xin","family":"Tee","sequence":"first","affiliation":[{"name":"Department of Radiology, Monash Medical Centre, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mithun","family":"Nambiar","sequence":"additional","affiliation":[{"name":"Department of Radiology, Monash Medical Centre, Clayton, Victoria, Australia"},{"name":"Faculty of Medicine, Nursing and Health Sciences, Monash University, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gautam","family":"Mahendru","sequence":"additional","affiliation":[{"name":"Department of Radiology, Monash Medical Centre, Clayton, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parminder","family":"Singh","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Nursing and Health Sciences, Monash University, Clayton, Victoria, Australia"},{"name":"Hip Arthroscopy Australia, Richmond, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,3,17]]},"reference":[{"key":"2025082623314135000_15.3.e247916.1","first-page":"1","article-title":"The epidemiology and demographics of legg-calv\u00e9-perthes' disease","volume":"2011","author":"Loder","year":"2011","journal-title":"ISRN Orthop"},{"key":"2025082623314135000_15.3.e247916.2","doi-asserted-by":"crossref","first-page":"365","DOI":"10.1016\/j.ocl.2011.04.009","article-title":"Principles of treating the sequelae of Perthes disease","volume":"42","author":"Wenger","year":"2011","journal-title":"Orthop Clin North Am"},{"key":"2025082623314135000_15.3.e247916.3","doi-asserted-by":"crossref","first-page":"2807","DOI":"10.2147\/JPR.S325665","article-title":"Latest evidence-based application for radiofrequency neurotomy (learn): best practice guidelines from the American Society of pain and neuroscience (ASPN)","volume":"14","author":"Lee","year":"2021","journal-title":"J Pain Res"},{"key":"2025082623314135000_15.3.e247916.4","doi-asserted-by":"crossref","first-page":"e144","DOI":"10.3928\/00904481-20160310-03","article-title":"Legg-Calv\u00e9-Perthes disease","volume":"45","author":"Divi","year":"2016","journal-title":"Pediatr Ann"},{"key":"2025082623314135000_15.3.e247916.5","doi-asserted-by":"crossref","first-page":"74","DOI":"10.11138\/ccmbm\/2017.14.1.074","article-title":"Legg-Calv\u00e9-Perthes disease: classifications and prognostic factors","volume":"14","author":"Rampal","year":"2017","journal-title":"Clin Cases Miner Bone Metab"},{"key":"2025082623314135000_15.3.e247916.6","first-page":"283","article-title":"Action physiologique des courants alternatifs","volume":"43","author":"d'Arsonval","year":"1891","journal-title":"CR Soc Biol"},{"key":"2025082623314135000_15.3.e247916.7","first-page":"761","article-title":"Zur elektrochirurgie","volume":"167","author":"Kirschner","year":"1931","journal-title":"Arch Klin Chir"},{"key":"2025082623314135000_15.3.e247916.8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1533-2500.2008.00231.x"},{"key":"2025082623314135000_15.3.e247916.9","doi-asserted-by":"crossref","first-page":"30","DOI":"10.5603\/AIT.2015.0003","article-title":"Cooled radiofrequency system relieves chronic knee osteoarthritis pain: the first case-series","volume":"47","author":"Bellini","year":"2015","journal-title":"Anaesthesiol Intensive Ther"},{"key":"2025082623314135000_15.3.e247916.10","doi-asserted-by":"crossref","first-page":"279","DOI":"10.36076\/ppj.2018.3.279","article-title":"Cooled Radiofrequency Neurotomy of the Articular Sensory Branches of the Obturator and Femoral Nerves -
