We present a review of the literature on classification and treatment of osteochondral defects of the talus. We report the case of an isolated Berndt and Harty grade II lesion treated with a fresh osteochondral allograft. We believe that fresh allograft osteochondral grafting of the talus is an excellent technique for symptomatic Berndt and Harty grade II or higher lesion of the talus without s...

Experience with fresh osteochondral allografting for cartilage defects in the knee now extends two decades. Clinical outcomes and basic scientific investigations have supported the theoretic basis for this procedure. At the University of California, San Diego, our experience has encouraged us to continue to offer this procedure as a primary treatment for both large and small articular cartilage...

The objective of this study was to test the hypothesis that mechanical properties of artificial osteochondral constructs can be improved by a tissue-engineered zone of calcification (teZCC) at the bone-hydrogel interface. Experimental push-off tests were performed on osteochondral constructs with or without a teZCC. In parallel, a numerical model of the osteochondral defect treatment was develo...

Background Extrusion of the meniscus has been reported to be correlated with progression of osteoarthritis. In cases with osteochondral lesions after extrusion of the meniscus, meniscal transplantation was the only surgical intervention. Recently, a novel procedure called arthroscopic centralisation has been developed to restore the meniscus function by centralising the midbody of the extruded ...

Objectives. The osteochondral junction can be a source of pain in both RA and OA. Growth of blood vessels and nerves from the subchondral bone into articular cartilage may mediate the association between joint pathology and symptoms. We have investigated associations between angiogenesis, inflammation and neurovascular growth factor expression at the osteochondral junction in human arthritis. M...

The development of osteochondral tissue engineered interfaces would be a novel treatment for traumatic injuries and aging associated diseases that affect joints. This study reports the development of a bilayered scaffold, which consists of both bone and cartilage regions. On the other hand, amniotic fluid-derived stem cells (AFSCs) could be differentiated into either osteogenic or chondrogenic ...

Osteochondral defects of the femoral head are exceedingly rare, with limited treatment options. Restoration procedures for similar defects involving the knee and ankle have been well described. In this report, we present a young patient who had a symptomatic osteochondral defect of the femoral head develop secondary to trauma and underwent subsequent treatment using a fresh-stored osteochondral...

Osteochondral lesions of the talus that have previously undergone surgical management or involve the shoulder region of the talus require methods other than microfracture for treatment. For those lesions that have failed microfracture and do not involve the shoulder of the talus, osteochondral autologous transfer is our preferred treatment of choice. Perpendicular access to the lesion, often by...

PURPOSE To study the morphology of the articulation of the knee of rabbits after the repairing of the defect osteochondral standardized with resorcina adhesive or metallic synthesis. METHODS The procedure was to the creation of the defect osteochondral in femoral medial condylus of the knee of 80 rabbits, The animals were distributed in two groups with continuations of 7 and 42 days and submi...

The optimum management for recurrent glenohumeral instability with significant humeral head defects remains controversial. The purpose of this study was to compare outcomes and recurrence rates between patients who underwent osteochondral substitute grafting and patients who underwent remplissage to treat recurrent shoulder instability from an engaging Hill-Sachs defect with a Bankart lesion. T...
