Anterior knee pain: A rare case of patellar osteoma osteoid

Anterior knee pain (AKP) is one of the most common musculoskeletal disorders and may cause severe disability and discomfort in children and in adolescents. Its etiology is heterogeneous and includes all causes of pain in the anterior aspect of the knee. Amongst rare causes, there are patellar tumors; in this paper we reported a unique case of patellar osteoma osteoid. In literature, nature and treatment of iuxta-articular osteoma osteoid remain controversial: some authors believe that iuxta-articular osteomas could lead to permanent deformity and advocate an early surgical treatment. Other authors report spontaneous regressions, good response to nonsteroidal anti-inflammatory drugs (NSAIDs) e risk of iatrogenic damages. In this paper, we reviewed current treatment concepts in view of our therapeutic choices.
