Cartilage defects of the hip cause significant pain and may lead to arthritic changes that necessitate hip replacement. We propose the use of fresh osteochondral allografts as an option for the treatment of such defects in young patients. Here we present the results of fresh osteochondral allografts for cartilage defects in 17 patients in a prospective study. The underlying diagnoses for the ca...

Treating displaced patellar bone fractures in growing children remains a challenge for orthopedic surgeons. Removal of loose bone fragments may prolong healing time and result in early onset osteoarthrosis. Therefore, primary fixation of osteochondral fragments is preferred. Metallic pin and screw implants are typically used for fixation, as there is little evidence available regarding the use ...

The dome of the talus is the part that articulates with the ankle mortice formed by the lower articular surfaces of tibia and fibula. A fracture of this part of the talus may be called a dome fracture. Such fractures are not common and the significance of the original radiographic appearance is not always appreciated. Definitive treatment is therefore often unnecessarily delayed ; this has been...

INTRODUCTION Isolated fracture of the trochlea is a rarely reported entity. To the best of our knowledge, only 15 cases have been published. We report the case of a patient with an isolated fracture of the trochlea and discuss through a literature review the underlying mechanisms and the clinical, radiological and therapeutic features of this lesion. This work will significantly advance our und...

The use of osteochondral allografts to treat focal osteochondral lesions continues to gain popularity, supported by long-term results. Clinicians must be knowledgeable concerning the possible risks of disease transmission, graft rejection, infection, and graft failure to advise the patient and obtain an informed consent. With advancing scientific and clinical research, future operative indicati...

We report the second case of osteochondritis dissecans (OCD) of the knee in identical twins (bilaterally in one and unilaterally in the other). Fixations with bio-absorbable pins, cylindrical osteochondral graft, and osteochondral mosaicplasty were all successful and bone union was achieved. We considered that genetic factors remain essential even if other factors (particularly repetitive traum...
