The altered anatomy results in biomechanical and biological problems that can be surgically addressed in adolescents or young adults with hip preservation procedures. This case report aims to demonstrate a customized surgical treatment performed on a 15-year-old male who developed painful hips with significant intra- and extra-articular impingement, secondary to bilateral Leg\u2013Calv\u00e9\u2013Perthes disease residual deformity. Intra-articular procedures were executed through a safe surgical dislocation of the hip, with a mosaicplasty using osteochondral autografts from the exceeding peripheral ipsilateral femoral head, a femoral head\u2013neck osteochondroplasty and a labrum repair. A relative lengthening of the femoral neck was also carried out with a trochanteric advancement to solve the extra-articular issues. On follow-up, he referred to a substantial improvement in pain and function, being his radiographic studies satisfactory. At 4 and 5\u2009years from surgery, the patient was able to exercise regularly with minimal complaints, with a Harris Hip Score of 85.85% and a Hip Outcome Score of 94.1% for activities of daily life and 86.1% for sports. In patients with hip deformity after healed Perthes disease, treatment strategies that address both the morphological disturbance of coxa magna, plana and breva, as well as the biological concerns arising from osteochondral injuries or labral tears, and mechanical dysfunctions lead to improvements in symptomatology, function and medium-term prognosis. Further procedures to address residual adaptative acetabular dysplasia would favor outcomes of conservative hip surgery in the sequelae of LCPD.<\/jats:p>","DOI":"10.1093\/jhps\/hnab021","type":"journal-article","created":{"date-parts":[[2021,6,23]],"date-time":"2021-06-23T16:49:46Z","timestamp":1624466986000},"page":"i9-i15","source":"Crossref","is-referenced-by-count":8,"title":["Bilateral femoral head reshaping and mosaicplasty in Legg\u2013Calv\u00e9\u2013Perthes disease residual deformity"],"prefix":"10.1093","volume":"8","author":[{"given":"\u00c1ngel","family":"Palaz\u00f3n-Quevedo","sequence":"first","affiliation":[{"name":"Pediatric Orthopaedic and Traumatology Department, Hospital Infantil Universitario Ni\u00f1o Jes\u00fas,\u00a0Av. de Men\u00e9ndez Pelayo 65, 28009, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda","family":"Gal\u00e1n-Olleros","sequence":"additional","affiliation":[{"name":"Pediatric Orthopaedic and Traumatology Department, Hospital Infantil Universitario Ni\u00f1o Jes\u00fas,\u00a0Av. de Men\u00e9ndez Pelayo 65, 28009, Madrid, Spain"},{"name":"Orthopaedic Surgery and Traumatology Department, Hospital Cl\u00ednico San Carlos, Calle Profesor Mart\u00edn Lagos s\/n 28004, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosa M","family":"Egea-G\u00e1mez","sequence":"additional","affiliation":[{"name":"Pediatric Orthopaedic and Traumatology Department, Hospital Infantil Universitario Ni\u00f1o Jes\u00fas,\u00a0Av. de Men\u00e9ndez Pelayo 65, 28009, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,6,23]]},"reference":[{"key":"2021070819532527500_hnab021-B1","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1302\/0301-620X.64B3.7096391","article-title":"Perthes\u2019 disease: is the epiphysial infarction complete?","volume":"64","author":"Catterall","year":"1982","journal-title":"J Bone Joint Surg Br"},{"key":"2021070819532527500_hnab021-B2","doi-asserted-by":"crossref","first-page":"e79","DOI":"10.1177\/0284185116642923","article-title":"The definite form of the Coxa Plana","volume":"57","author":"Waldenstr\u00f6m","year":"2016","journal-title":"Acta Radiol"},{"key":"2021070819532527500_hnab021-B3","doi-asserted-by":"crossref","first-page":"1095","DOI":"10.2106\/00004623-198163070-00006","article-title":"The natural history of Legg-Calv\u00e9-Perthes disease","volume":"63","author":"Stulberg","year":"1981","journal-title":"J Bone Joint Surg Am"},{"key":"2021070819532527500_hnab021-B4","first-page":"28","article-title":"Legg-Calv\u00e9-Perthes disease: results of long-term follow-up","author":"Weinstein","year":"1985","journal-title":"Hip"},{"key":"2021070819532527500_hnab021-B5","doi-asserted-by":"crossref","first-page":"372","DOI":"10.2106\/00004623-200602000-00017","article-title":"The prevalence of acetabular retroversion among various disorders of the hip","volume":"88","author":"Ezoe","year":"2006","journal-title":"J Bone Jt Surg Am"},{"key":"2021070819532527500_hnab021-B6","doi-asserted-by":"crossref","first-page":"49","DOI":"10.1093\/jhps\/hnaa003","article-title":"The acetabulum in healed Legg-Calv\u00e9-Perthes disease is cranially retroverted and associated with global reduction of femoral head coverage: a matched-cohort study","volume":"7","author":"Maranho","year":"2020","journal-title":"J Hip Preserv Surg"},{"key":"2021070819532527500_hnab021-B7","doi-asserted-by":"crossref","first-page":"2441","DOI":"10.1007\/s11999-011-2187-1","article-title":"Low early failure rates using a surgical dislocation approach in healed Legg-Calv\u00e9-Perthes disease","volume":"470","author":"Shore","year":"2012","journal-title":"Clin Orthop Relat Res"},{"key":"2021070819532527500_hnab021-B8","doi-asserted-by":"crossref","first-page":"117","DOI":"10.1093\/jhps\/hnz014","article-title":"Complications associated with combined surgical hip dislocation and periacetabular osteotomy for complex hip deformities","volume":"6","author":"Edelstein","year":"2019","journal-title":"J Hip Preserv Surg"},{"key":"2021070819532527500_hnab021-B9","year":"1965"},{"key":"2021070819532527500_hnab021-B10","doi-asserted-by":"crossref","first-page":"1119","DOI":"10.1302\/0301-620X.83B8.0831119","article-title":"Surgical dislocation of the adult hip a technique with full access to the femoral head and acetabulum without the risk of avascular necrosis","volume":"83-B","author":"Ganz","year":"2001","journal-title":"J Bone Joint Surg Br"},{"key":"2021070819532527500_hnab021-B11","first-page":"26","article-title":"A new periacetabular osteotomy for the treatment of hip dysplasias.
