Arthrotomic implantation of BioSeed®-C. (a) BioSeed®-C was armed in each corner with resorbable threads secured by threefold knots. (b) In every corner of the defect, k-wires were drilled using the inside-out technique. (c) Guiding threads were pulled through the femoral bone using the k-wires, and the knots were guided into the subchondral bone. (d) The knots serve as anchors, seizing the subchondral bone and securely fixing the graft.
