(a) Image of hydrogel plug consisting of PAMPS/PDMAAm DN. (b) Schematic of proposed implantation of DN plug into an osteochondral defect within the patellofemoral joint at the femoral groove. (c) Schematic of the cross-section of the plug within the defect at the femoral groove (d) Histology revealing fibrous and bone tissues flanking the DN-gel implanted defect (left) and Safranin-O-stained areas at the gel-bone interface (right) (e) The sham operated patella (left) and the DN-gel implanted patella (right) reveal a nearly regular and natural appearance at 4 weeks.
