Akio Sakamoto, Shuichi Matsuda
BACKGROUND: Many normal variants of bones on plain radiographs have been reported. CASE PRESENTATION: In the current report, a 14-year-old Asian girl noticed an occasional slight elbow pain. She had no traumatic episode. Plain radiographs showed a well-defined osteolytic lesion with a sclerotic rim, which was continuous with the normal subarticular bone in the distal humerus. Magnetic resonance imaging revealed that the defect area seen on the plain radiograph showed low-signal to iso-signal intensity on T1-weighted images and slightly high-signal intensity on T2-weighted fat suppression images...

Recurrent or chronic activity related knee pain is common in young athletes. Numerous intrinsic conditions affecting the knee can cause such pain. In addition, knee pain can be referred pain from low back, hip or pelvic pathology. The most common cause of knee pain in young athletes is patellofemoral pain syndrome, or more appropriately termed idiopathic anterior knee pain. Although, numerous anatomical and biomechanical factors have been postulated to contribute the knee pain in young athletes, the most common underlying reason is overuse injury...

BACKGROUND: Large osteochondral defects of the knee are a challenge for regenerative treatment. While matrix-guided autologous chondrocyte transplantation (MACT) represents a successful treatment for chondral defects, the treatment potential in combination with bone grafting by cancellous bone or bone block augmentation for large and deep osteochondral defects has not been evaluated. PURPOSE: To evaluate 1- to 3-year clinical outcomes and radiological results on magnetic resonance imaging (MRI) after the treatment of large osteochondral defects of the knee with bone augmentation and MACT...

The surgical treatment of knee articular focal lesions may offer heterogeneous clinical results. Osteochondritis dissecans (OCD) lesions showed to heal better than degenerative lesions (DL) but the underlying biological reasons are unknown. We evaluated the basal histological and immunohistochemical characteristics of these lesions analyzing a series of osteochondral fragments from young patients with similar age but presenting different etiology. Osteochondral tissue samples were stained with Safranin O and graded using a histological score...

Osteochondritis dissecans (OCD) of the capitellum is a common disorder that causes pain and functional limitation in the adolescent elbow. Although conservative management is the first line of treatment, surgical intervention is usually recommended for patients with persistent mechanical symptoms, loose bodies, or unstable lesions. Elbow arthroscopy has become the gold standard to evaluate and treat symptomatic OCD lesions. Arthroscopic debridement and bone marrow stimulation have been shown to yield good short-term results...

BACKGROUND: Capitellar osteochondritis dissecans (OCD) is a debilitating condition of unknown etiology for which various arthroscopic treatments are available. Prior data suggest that greater than 75% of the capitellum can be visualized arthroscopically through a dual lateral portal approach. However, there is no literature assessing arthroscopic visualization of the capitellum via alternative portals. PURPOSE: To determine the percentage of capitellum visualized using the dual lateral, distal ulnar and soft spot, and posterolateral and soft spot portal configurations in a cadaver model...

Osteochondritis dissecans (OCD) of the elbow capitellum is a common disorder that causes pain and functional limitation in the athletic adolescent elbow. Many surgical options have been proposed over the years, but none has stood the test of time. A recent well-written systematic review highlights the treatment options and recognizes a growing trend toward osteochondral allograft transplantation as the ideal solution. Unfortunately, the study also underscores the paucity of evidence on which we base our treatment decisions for OCD of the elbow in the young athlete...

This article is a review of the current understanding of the etiology, pathogenesis, and how to diagnose and treat knee osteochondritis dissecans (OCD) followed by an analysis of and outcomes of the treatments available. OCD is seen in children and adolescents with open growth plates (juvenile OCD) and adults with closed growth plates (adult OCD). The etiology of OCD lesions remains unclear and is characterized by an aseptic necrosis in the subchondral bone area. Mechanical factors seem to play an important role...

Cartilage damage of the knee is common and may present in patients as a variety of symptoms. These conditions can be classified based on location, etiology, and/or pathophysiology. A systematic approach to the evaluation and classification of chondral injuries helps improve definitive management. The four most common types of knee cartilage damage are osteochondritis dissecans, incidental chondral defects, patellofemoral defects, and defects encountered after meniscectomy.

Although osteochondritis dissecans (OCD) has been a recognized condition for more than 100 years, our understanding of the etiology, natural history, and treatment remains poorly characterized. OCD most commonly affects the knee, followed by the elbow and ankle. Adolescents and young adults are most commonly affected. Patients present with vague, often intermittent symptoms and generally have no history of acute injury. Although diagnosis can be made with plain radiographs, treatment decisions are generally based on MRI...

Osteochondral allografts are used to treat many different conditions as acute traumatic large-sized lesions, degenerative osteoarthritis, osteochondritis dissecans, avascular necrosis or in case of failure of previous procedures particularly in young patients for whom primary prosthesis is not desirable. Fresh allografts present the advantage of having mature viable hyaline cartilage, not causing donor morbidity, allowing the restoration of even large defects in a single surgical session. Conversely, they could account for risks of disease transmission, immunologic reactions, and for limited availability...
