WebThe pore sizes of the scaffolds ranged from 25 to 110 μm, the porosity was 70%, 82%, 86%, and 90%, respectively. ... The results revealed that MSCs that were loaded in the PLA/HA scaffolds presented notable bone ingrowth, in addition to improved collagen fiber deposition along the new bone and tendon. WebThe microporosity of PCL controlled by 3-D printing promotes rapid fibrovascular ingrowth without granulation-tissue formation. 6 Once fibrovascular ingrowth occurs, the mesh is stabilized, which decreases the likelihood of extrusion and/or infection of the implant. 22 After the clinical trial, we plan to obtain operative results that include the maintenance of … did halo reach have forge
