Transplantation of nasal-chondrocyte engineered construct for the treatment of the full-thickness cartilage defect in a 28-year-old athlete [19]. (a) Exposure of the full-thickness cartilage defect of the medial femoral condyle via mini-arthrotomy. (b) Debridement of the cartilage lesion to remove the damaged cartilage and establish adequate shouldering of the lesion. (c) Tissue-engineered cartilage cut to the right shape and ready for implantation. (d) Tissue-engineered cartilage inserted in the cartilage defect and secured by 5–0 monofilament absorbable sutures.
