We used fresh small-fragment osteochondral allografts to reconstruct post-traumatic osteochondral defects in 126 knees of 123 patients with a mean age of 35 years. At a mean follow-up of 7.5 years (2 to 20), 108 knees were rated as successful (85%) and 18 had failed (15%). The factors related to failure included age over 50 years (p = 0.008), bipolar(More)
Allograft bone was used to reconstruct a defect in the proximal aspect of the tibia or the distal aspect of the femur, or both, in thirty knees of twenty-eight patients who had a revision total knee arthroplasty. The average age of the patients at the time of the index procedure was 65.8 years (range, twenty-four to eighty-nine years). At an average of(More)
Fresh osteochondral allografts were used for post-traumatic knee defects >3 cm in diameter and 1 cm in depth. Harvesting of the grafts was carried out within 24 hours of the death of the donor, and implantation into the recipient was carried out within 72 hours. The grafts were unipolar, fixed by screws, and combined with realignment osteotomy if a(More)
Osteoblastoma is a relatively rare benign bone tumor, most often located in the vertebral column or metaphysis of the long bones, particularly the femur and the tibia. Periosteal osteoblastoma is the least common type. Exostosis-like appearance is not common even in periosteal osteoblastoma, a very rare type of this tumor. In addition, an intraarticular(More)
Habitual dislocation of the hip (HDH) in children is a rare entity and can be a causative factor for popping or snapping hip which is a common problem in children with good prognosis. We report a case of HDH in a 9 year old girl who was suffering from frequent snapping hip at night, its course and treatment process.
To study the direction and biomechanical consequences of hip center of rotation (HCOR) migration in Crowe type III and VI hips after total hip arthroplasty, post-operative radiographs and CT scans of several unilaterally affected hips were evaluated. Using a three-dimensional model of the human hip, the HCOR was moved in all directions, and joint reaction(More)
Periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries.

The natural history of an untreated case of a Developmental Dysplasia (Dislocation) of the Hip (DDH) associated with multiple congenital abnormalities is reported in a 55-years-old man. The patient's complaints and the varieties of the typical manifestations emerged in other parts of the body throughout the life are reviewed and discussed as comorbidities(More)
