We report a case of a 13\u2010year\u2010old boy with a stiff Perthes\u2019 hip that was nonresponsive to prolonged nonsurgical treatment. Imaging revealed Catterall group IV Perthes\u2019 disease in an advanced reossification stage, with a focal defect in the weight\u2010bearing area of the capital femoral epiphysis. A focal, compressible chondral elevation was detected on hip arthroscopy; on incision, flocculent fluid was released. After the cyst was excised, microfracture revascularization of the chondral defect was undertaken. Postoperatively, the patient had immediate pain relief, correction of deformity, and restoration of painless range of motion; this has continued for 4 years since surgery was performed. Persistence of an unhealed necrotic segment in Perthes\u2019 disease has traditionally been associated with osteochondritis dissecans; however, in this case, the unhealed and nonossified segment produced an elevated painful chondral cyst that caused spasm and stiffness of the hip. Although 2 distinct types of chondral lesions have been described in Perthes\u2019 disease, stiffness arising because of these lesions has not been reported. Patients with this unusual third type of chondral lesion of the capital femoral epiphysis, which causes persistent stiffness in Perthes\u2019 hip, may be identified and successfully treated with the use of arthroscopic techniques.<\/jats:p>","DOI":"10.1016\/j.arthro.2006.05.022","type":"journal-article","created":{"date-parts":[[2006,11,28]],"date-time":"2006-11-28T10:30:53Z","timestamp":1164709853000},"source":"Crossref","is-referenced-by-count":4,"title":["Arthroscopic Chondral Cyst Excision in a Stiff Perthes\u2019 Hip"],"prefix":"10.1002","volume":"23","author":[{"given":"Dinshaw N.","family":"Pardiwala","sequence":"first","affiliation":[{"name":"Department of Orthopaedics King Edward VII Memorial Hospital Mumbai India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taral V.","family":"Nagda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics King Edward VII Memorial Hospital Mumbai India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,11,29]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-5919(05)70283-0"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1053\/ar.1999.v15.0150081"},{"key":"e_1_2_2_4_1","first-page":"160","article-title":"Arthroscopic treatment of the sequelae of Legg\u2010Calve\u2010Perthes\u2019 disease","volume":"75","author":"Lechevallier J.","year":"1993","journal-title":"J Bone Joint Surg Br"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453679408994608"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197557040-00011"}],"container-title":["Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0749806306007547?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0749806306007547?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.arthro.2006.05.022","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1016\/j.arthro.2006.05.022","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.arthro.2006.05.022","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,15]],"date-time":"2026-03-15T09:15:32Z","timestamp":1773566132000},"score":1,"resource":{"primary":{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/10.1016\/j.arthro.2006.05.022"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2006,11,29]]},"references-count":5,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2007,8]]}},"alternative-id":["10.1016\/j.arthro.2006.05.022"],"URL":"https:\/\/doi.org\/10.1016\/j.arthro.2006.05.022","archive":["Portico"],"relation":{},"ISSN":["0749-8063","1526-3231"],"issn-type":[{"value":"0749-8063","type":"print"},{"value":"1526-3231","type":"electronic"}],"subject":[],"published":{"date-parts":[[2006,11,29]]}}}
