Intra-articular osteoid osteoma of the knee: clinical and therapeutical particularities

The intra-articular osteoid osteoma (10-13% of the cases) is often difficult to identify. They present frequent atypical clinical signs and radiological images that eventually lead to inadequate treatment. For example, it has been observed that this pathology leads to inappropriate arthroscopies (up to 40%). Meniscal tear and then osteochondritis were initially suspected on a patient with an intra-articular osteoid osteoma at the tibia level. For the treatment, any damage of the cartilage has to be avoided. Thermoablation with radiofrequency is the treatment of choice

Lésions du ligament croisé antérieur de l'enfant [Anterior cruciate ligament injuries in children].

An increasing number of anterior cruciate ligament injuries are now seen in children and girls seem to be equally affected. Such neglected or untreated lesions could be the cause of early degenerative changes. Recently, many authors support the trend toward early surgical management in skeletally immature patients with complex meniscal tear or recurrent knee instability after proper rehabilitation. Improvement in pediatric knowledge and surgical techniques tend to support a tendency for more surgical treatment in children. The type of management is choosing according to history and physical examination. Magnetic resonance imaging is a useful tool not only for diagnosis but also for surgical treatment planning. We usually recommend anterior cruciate ligament reconstruction in children with knee instability or with further damages to the joint.
