Aneurysmal bone cysts, which develop from a prior lesion such as a chondroblastoma, are seldom seen in the patella. The authors report a case of a 36-year-old man who presented with 2 years of right knee pain without calor, erythema, pain on palpation, or abnormal range of motion. Radiological studies suggested aneurysmal bone cyst. The lesion was excised with curettage and the residual cavity filled with autogenous bone graft. Histopathology revealed chondroblastoma associated with a secondary aneurysmal bone cyst. In the follow-up period, the patient demonstrated normal joint activities with no pain. Normal configuration of the patella and bone union were shown on plain radiographs. The authors present a review of the literature of all cases of patellar chondroblastoma with aneurysmal bone cyst. This case is the 14th report of aneurysmal bone cyst arising in a chondroblastoma of the patella. According to the literature, computed tomography and magnetic resonance imaging are useful in the study of these lesions. The pathologic diagnosis is based on the presence of chondroblastoma and aneurysmal bone cyst. Treatment of this lesion includes patellectomy, curettage alone, and curettage with bone grafting. Despite the risk of recurrence of this lesion in the patella, the authors first recommend curettage followed by filling the cavity with bone graft. To protect the anterior tension of the patella intraoperatively, the bone window should be made at the medial edge of the patella to perform the curettage and bone grafting.<\/jats:p>","DOI":"10.3928\/01477447-20131219-23","type":"journal-article","created":{"date-parts":[[2014,2,18]],"date-time":"2014-02-18T17:06:39Z","timestamp":1392743199000},"source":"Crossref","is-referenced-by-count":7,"title":["Chondroblastoma of the Patella With Aneurysmal Bone Cyst"],"prefix":"10.3928","volume":"37","author":[{"given":"Honglue","family":"Tan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengning","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bing","family":"Yue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yiming","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"You","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00361426"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-199703000-00028"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.3928\/0147-7447-20000401-13"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200108000-00007"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0030-1247821"},{"issue":"3","key":"e_1_3_1_7_2","first-page":"391","article-title":"Tumours and tumour-like lesions of the patella: a report of eight cases","volume":"74","author":"Saglik Y","year":"2008","unstructured":"Saglik Y, Yildiz Y, Basarir K, Tezen E, G\u00fcner D.
