We present a case of post-traumatic osteonecrosis of the radial head in a 13-year-old boy which was treated with costo-osteochondral grafts. A satisfactory outcome was seen at a follow-up of two years and ten months. Although costo-osteochondral grafting has been used in the treatment of defects in articular cartilage, especially in the hand and the elbow, the extension of the technique to mana...

“Osteochondral lesion of the talus” (OLT) is a broad term, representing acute and chronic disorders of the osteochondral junction. They mostly occur at the convex parts of the talar dome. At time of diagnosis signs of degenerative joint disease are rarely seen. The terminology is varied including terms like osteochondritis dissecans, ostechondral fractures, transchondral fractures. Etiology of ...

Localized osteochondral and chondral lesions of the knee are commonly encountered in orthopaedic practice. They may become symptomatic with patients experiencing pain, swelling, and mechanical symptoms. These lesions have limited ability to heal and may progress to osteoarthritis. This presents an especially difficult clinical problem in young, high-demand individuals. This has led surgeons to ...

Osteochondral loose bodies are uncommon in the temporomandibular joint but occur relatively frequently in the large joints such as the knee, elbow and hip.’ They may be associated with synovial osteochondromatosis or may occur secondary to osteoarthritis, intracapsular fractures, osteochondritis dissecans, rheumatoid arthritis, syphilis or tuberculosis.2,3,4 A survey of literature reveals aroun...

Osteochondral lesions of the talus can present as a late complication of ankle injuries. As the talus is largely covered by articular cartilage, it has a limited ability for repair. Early and accurate diagnosis is important as talar integrity is required for optimal function of the ankle. The common presentation is chronic ankle pain with a history of ankle trauma. Conservative treatment involv...

Purpose: to verify the capability of scaffold-supported bone marrow-derived cells to be used in the repair of osteochondral lesions of the talus. Methods: using a device to concentrate bone marrowderived cells, a scaffold (collagen powder or hyaluronic acid membrane) for cell support and platelet gel, a one-step arthroscopic technique was developed for cartilage repair. In a prospective clinica...

BACKGROUND There has been increased interest in one-step cell-free procedures to avoid the problems related to cell manipulation and its inherent disadvantages. We have studied the chondrogenic induction ability of a PAMPS/PDMAAm double-network (DN) gel and found it to induce chondrogenesis in animal osteochondral defect models. The purpose of this study was to investigate whether the healing p...

BACKGROUND Tibiotalar arthritis in the young, active patient is a debilitating condition with limited treatment options. Bipolar tibiotalar fresh osteochondral allograft transplantation was conceived as a possible alternative to arthrodesis and arthroplasty. We reported our experience with bipolar ankle osteochondral allografts for the treatment of tibiotalar joint arthritis. METHODS Between ...

background: autogenous osteochondral grafting of articular defect in weight-bearing surface of large joints has proven to be a proper biomechanical and physiological solution for localized full-thickness defects. objective: to study the gross and histopathological results of mosaicplasty in an animal model (sheep’s medial femoral condyle), evaluating the factors of defect and graft size, assess...
