Epidemiology
Patellar tumours represent just 0.1% of all primary bone tumours 1.
Clinical presentation
Patients may present with anterior knee pain and/or a palpable mass 1,3.
Pathology
Aetiology
Most (~80%) patellar tumours are benign. A non-extensive list of causes is 1-3:
-
benign
- giant cell tumour (most common)
- chondroblastoma (second most common)
- aneurysmal bone cyst
- malignant
