Objective: Patella is a sesamoid bone which develops in the quadriceps tendon. It is an uncommon site for neoplasms. The most common primary tumors which involve patella are benign. These include chondroblastoma, giant cell tumor (GCT) and aneurysmal bone cyst. Malignant lesions are less common in patella. These encompass metastasis, osteosarcoma and hemangioendothelioma. The most common compla...

abstract patella is a relative uncommon site for chondroblastoma. most of cases of chondroblastoma in patella reported in literature are treated with patellectomy. we treated a large chondroblastic lesion in patella of an 18- year-old male with curettage, burring & bone graft and the result was satisfactory after 3 years post operation.

background: abnormal patellar height is associated with anterior knee pain and several conditions that affect the patellofemoral joint. the aim of this study was to 1) report the incidence of patella alta and patella baja and 2) investigate whether the normal limits of the insall-salvati ratio is applicable in adult middle-easterners. methods: a radiographic review of the lateral radiographs of...

conclusions in simultaneous bilateral patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. however, personality of the fracture determines salvage versus sacrifice of the patella. case presentation we report a rare case of isolated, traumatic bilateral patella fracture with unusual fracture patterns and briefly r...

OBJECTIVE The methods most used for patellar height measurement were compared with the plateau-patella angle method. METHODS A cross-sectional study was conducted, in which lateral-view radiographs of the knee were evaluated using the three methods already established in the literature: Insall-Salvati (IS), Blackburne-Peel (BP) and Caton-Deschamps (CD). These were compared with the plateau-pa...

BACKGROUND Whilst patellofemoral pain is one of the most common musculoskeletal disorders presenting to orthopaedic clinics, sports clinics, and general practices, factors contributing to its development in the absence of a defined arthropathy, such as osteoarthritis (OA), are unclear.The aim of this cross-sectional study was to describe the relationships between parameters of patellofemoral ge...

The purpose of this study is to determine if patellar maltracking is more prevalent among patellofemoral (PF) pain subjects with patella alta compared to subjects with normal patella height. We imaged 37 PF pain and 15 pain free subjects in an open-configuration magnetic resonance imaging scanner while they stood in a weightbearing posture. We measured patella height using the Caton-Deschamps, ...

To our knowledge, this is the first case of synovial osteochondromatosis in a patient presenting with a double patella-like condition. The true duplication of the patella, which is called double patella, is extremely rare. In our case, the operative and histopathological findings showed that the double patella-like condition was secondarily induced by synovial osteochondromatosis. Synovial oste...
