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...

We have investigated the effect of the insufficient autologous osteochondral graft on healing of the large articular cartilage defect using a rabbit model. An osteochondral defect, 7 mm in diameter, was made on the patellar groove of the femoral condyle and repaired with two surgical procedures: Group I, the osteochondral fragment as half as the defect was grafted. The graft was unstable and th...

Patellar osteochondral lesions are common and particularly disabling injuries that can affect young and highly active patients. If enough functional impairment, ranging from difficulty climbing stairs to pain with squatting, is present, surgical treatment may be warranted. For the treatment of these lesions, various techniques have been described, including autologous osteochondral transplantat...

Symptomatic osteochondral lesions of the knee pose a considerable treatment challenge to orthopaedic surgeons, particularly when they occur in young active patients. The prognosis of osteochondral defects is worse when the defect is sizable, when it is located in a weight-bearing portion of the knee, and when there is considerable bone loss. Hyaline cartilage is unable to heal spontaneously bec...

Surgical reconstruction of articular surfaces by transplantation of osteochondral autografts has shown considerable promise in the treatment of focal articular lesions. During mosaicplasty, each cylindrical osteochondral graft is centred over the recipient hole and delivered by impacting the articular surface. Impact loading of articular cartilage has been associated with structural damage, los...

Allografting and autografting of osteochondral tissues is a promising strategy to treat articular cartilage lesions in damaged joints. We developed a new model of fresh osteochondral allografting using the entire rabbit trochlea. The objective of the current study was to demonstrate that this model would achieve reproducible graft-host healing and maintain normal articular cartilage histologic...

BACKGROUND Autologous and allogeneic osteochondral grafts have been used to repair damaged or diseased cartilage. There are drawbacks to both of these methods, however. Another possible source for osteochondral grafting is photooxidized xenograft scaffolds. The purpose of this study was to evaluate the adaptive immune response to unprocessed and photooxidized xenogeneic osteochondral grafts in ...

Osteochondrosis might reduce the performance of slaughter pigs, longevity of sows and animal welfare. The aim of the present work was to describe the prevalence in Swiss breeds and to analyse the genetic background of osteochondral lesions. Between January 2002 and December 2005, about 9500 station-tested pigs were examined for several exterior traits before slaughtering at the Swiss pig perfor...
