The aim of this study was to evaluate histopathological changes in the recipient site after transplantation of stored osteochondral allografts into articular cartilage defects in 8 dogs. In all dogs a single osteochondral allograft was transplanted into articular cartilage lesions. The results of the completed surgeries include a 12-month follow-up study. It was found that the stored osteochond...

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...

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...

PURPOSE To evaluate the long-term outcome following use of osteochondral autografts for the treatment of osteonecrosis of the femoral condyle. METHODS Clinical, radiographic and arthroscopic findings were evaluated at follow-up. Patients were 14 women and 2 men, with a mean age of 64.9 years (range, 58-74 years). The osteochondral lesion was equivalent to Lotke 1-B in 12 knees, and was equiva...

We investigated the use of a commercial spectrocolorimeter and the application of two color models (L* a* b* colorimetric system and spectral reflectance distribution) to describe and quantify cartilage plugs in a rabbit model of osteochondral autografting. Osteochondral plugs were removed and then replaced in their original positions in Japanese white rabbits. The rabbits were sacrificed at 4 ...

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 ...

Abstract Background The hemi-hamate arthroplasty is utilised for the management of complex fracture-dislocations injuries proximal interphalangeal joints (PIPJ) fingers. PIPJ outcomes are well described, including post-operative range motion, grip strength and osteochondral graft union. However, there a paucity evidence analysing rate donor site morbidity complications. This systematic review a...

The aim of study is to document our experience and intra-articular findings at time routine ankle arthroscopy during open reduction internal fixation (ORIF) contribute the growing body literature that shows this be a safe effective treatment. This retrospective review fractures who were treated with ORIF by single surgeon. patients’ charts including operative reports, office notes, images revie...
