We compared fibrin sealant, polydioxanone (PDS) pins and Kirschner wires in the fixation of osteochondral fractures in rabbit knees. Standardised osteochondral fractures of the right medial femoral condyle were made in 56 adult New Zealand white rabbits. There were equal groups of control knees, and those which had Kirschner-wire, fibrin-sealant or PDS-pin fixation. No external immobilisation w...

BACKGROUND Replacement of diseased areas of the joint with tissue-engineered osteochondral grafts has shown potential in the treatment of osteoarthritis. Bioactive glasses are candidates for the osseous analog of these grafts. QUESTIONS/PURPOSES (1) Does Bioactive Glass 13-93 (BG 13-93) as a subchondral substrate improve collagen and glycosaminoglycan production in a tissue-engineered cartila...

This study evaluated complications associated with implant depth in headless compression screw treatment of an osteochondral fracture associated with a traumatic patellar dislocation in a 21-year-old woman. Computed tomography and X-rays showed one lateral fracture fragment measuring 25 × 16 mm. Osteosynthesis was performed with two headless compression screws. Five months later, the screws wer...

OBJECTIVE The present study aimed to report the results of the first series of cases of fresh ostechondral allografts in the knee joint in Brazil with a minimum follow-up of two years. METHODS A protocol of procurement, harvesting, processing, and utilization of fresh osteochondral allografts in the knee joint was established, beginning with legislation modifications, graft harvesting techniq...

Treatment of chondral and osteochondral knee lesions in young patients remains a challenge for orthopedic surgeons. The repair techniques currently available in Brazil, such as debridement, microfracture and autologous osteochondral transplantation are insufficient for treating large chondral and osteochondral lesions. Fresh homologous osteochondral transplants have been used in the knee joint ...

We report a case of dorsal radiocarpal fracture dislocation with dissociation of the distal radioulnar joint. Closed reduction was unsuccessful due to interposition of the osteochondral fragments and open reduction and fixation was carried out with a satisfactory end result. The advantages of volar approach and use of external fixator in the management of this injury are discussed.

Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. A variety of terms have been used to refer to this clinical entity including osteochondritis dissecans, osteochondral fracture, and osteochondral defect. Whether OLT of the talus is a precursor to more generalized arthrosis of the ankle remain unc...

PURPOSE The purpose of this study was to document and compare the incidence of intra-articular hip pathologic findings identified using arthroscopy versus conventional imaging in patients with acute trauma to the hip. METHODS This was a blinded prospective case series study designed to review the incidence of intra-articular pathologic disorders in patients with post-traumatic injury between ...

 Background: To determine the efficacy of different antiseptic solutions (Control group (I), Antibiotic solution (II), Chlorhexidine 0.4% (III), and povidone – iodine 10% (IV)) in sterilizing contaminated osteochondral plugs. Methods: Under sterile conditions, the femoral head and condyles of 20 rabbits were removed and cut into equal osteochondral pieces. A total of 200 osteochondral specimens...
