Bioprinting Cartilage Grafts
Bioprinting is an emerging technology for the fabrication of patient-specific, anatomically-complex tissues and organs. A novel bioink was developed based on two unmodified regulatory-compliant polysaccharides, gellan and alginate, which undergoes cell friendly gelation in the presence of cations. Rheological properties of the bioink revealed optimal shear thinning and shear recovery properties...
متن کاملUse of genetically modified muscle and fat grafts to repair defects in bone and cartilage.
We report a novel technology for the rapid healing of large osseous and chondral defects, based upon the genetic modification of autologous skeletal muscle and fat grafts. These tissues were selected because they not only possess mesenchymal progenitor cells and scaffolding properties, but also can be biopsied, genetically modified and returned to the patient in a single operative session. Firs...
متن کاملReconstruction of the anterior cruciate ligament:a comparison between bone-patellar tendon-bone grafts and four-strand hamstring grafts
Background :Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The choice of graft for (ACL) reconstruction remains controversial. This prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (BPTB) grafts and four-strand semitendinosus-gracilis (ST) grafts for ACL reconstruction over a 3-year follow-up inte...
متن کاملVascularized bone grafts to the upper extremities
Materials and methods The reconstructed site was the humerus in 15 cases, the radius, the ulna or the wrist joint in 22 cases, carpal or metacarpal bone in 52. The etiologies consisted of three traumatic bone defects, 13 traumatic nonunions of long bone, two osteonecroses of the humeral head, eight osteomyelitis, nine case after resections of bone tumor, two congenital pseudoarthroses of the ul...
متن کاملVascularized bone grafts to the upper extremities.
From 1979 to 1995 in our clinic, vascularized bone grafting was performed in 29 patients with large bone defects, established nonunion, congenital pseudoarthrosis, or avascular necrosis in the upper extremity. Four patients had traumatic bone defects, six had posttraumatic nonunions, two had congenital pseudoarthroses, five had amputations, nine had defects following tumor resection, and three ...
