Athletes injured from sports-related injuries can be cured with artificial 3D printed fabrics developed by researchers at Rice University and the University of Maryland.
"Scaffolds reproduce the physical characteristics of the hard bone of osteochondral tissue under a compressible layer of cartilage that appears as the smooth surface at the ends of long bones," according to Tribute India.
Athletes' performance is affected when bones hurt, even with small cracks. Disabling arthritis can also result from these injuries. The results of their research were published in the journal Acta Biomaterialia, in which it was difficult to replicate the cartilage gradient in the bone and its porosity.
"Athletes are disproportionately affected by these injuries, but they can affect everyone," said Sean Bittner. A degree student at Rice University.
"I think it will be a powerful tool to help people with common sports injuries," said Bittner in a statement. The process makes it possible to copy the tissue that is transformed into bone from cartilage.
Scientists have created scaffolding by printing mixtures of polymers for cartilage and bone ceramic with encrusted pores that are permeable to the patient's blood vessels and cells, thus allowing their integration into the body. 39, bone and cartilage.
"Most of the time, the composition will be the same from one patient to the other.The porosity is included so that the vascular system can grow from the native bone. We do not have to make the blood vessels ourselves, "said Bittner.
Recommendations for future research include how to print an osteochondral implant that is compatible with the patient.
