The intra-articular osteoid osteoma (10% of cases) is a rare clinical finding. Based on atypical clinical signs and various radiological results the period to obtain a diagnosis and initiate the appropriate treatment is often very long. This case reports on a 32-year old female patient with knee pain on flexion and stress, which rarely occurred at night. Radiofrequency ablation (RFA) was contraindicated for IAOO in the trochlea femoris due to the direct subchondral location. Therefore, surgical rehabilitation by means of a cartilage-bone transplantation was carried out.

Osteoid Osteoma (OO) is a common primary bone tumor that often presents with night pain in younger orthopedic patients. Although typically extra-articular, intra-articular presentations may be difficult to diagnose. While magnetic resonance imaging (MRI) provides excellent detailed imaging of the articular surface, it has been reported to lead to occasional misdiagnosis given limitations in spatial resolution, particularly for smaller lesions.

Background: Magnetic resonance imaging (MRI), which does not involve ionizing radiation, is the preferred imaging modality for diagnosing osteoid osteoma (OO), an ailment more common in children and young adults.
Purpose: This study aims to perform a literature review and delineate the MRI findings of OO lesions in patients exhibiting varying radiological features across different regions.
Materials And Methods: A retrospective study included 63 patients diagnosed with OO through MRI, assessed independently by two blinded radiologists using both standard and dynamic contrast-enhanced MRI techniques.

Osteoid osteoma (OO) is the third most prevalent benign bone neoplasm in children. Although it predominantly affects the diaphysis of long bones, OO can assume an intra-articular location in the epiphysis or the intracapsular portions of bones. The most common location of intra-articular OO is the hip joint.

Osteoarthritis (OA) is a chronic inflammatory joint disease characterized by progressive cartilage degeneration, synovitis, and osteoid formation. In order to effectively treat OA, it is important to block the harmful feedback caused by reactive oxygen species (ROS) produced during joint wear. To address this challenge, we have developed injectable nanocomposite hydrogels composed of polygallate-Mn (PGA-Mn) nanoparticles, oxidized sodium alginate, and gelatin.
