“…111 Generally, ossification initiates from the first rib cartilage and progresses up to the twelfth rib. 100 Costal cartilage calcification is closely associated with ageing. [112][113][114] Severe calcification of the costal cartilage might increase the incidence of pneumothorax due to perichondrium adhesion.…”

“…93,99 For costal cartilage transplantation, preoperative evaluation is very important, and the size of harvested cartilage should be sufficient. 100 The surgical technique of transverse slicing of the sixth–seventh costal cartilaginous junction may yield adequate cartilage and was reported as an effective method to prevent warping. Warping of the cartilage may cause the loss of press-fit stability, which suggests that cartilage fixation is an essential procedure.…”

It is a great challenge to cure symptomatic lesions and considerable defects of hyaline cartilage due to its complex structure and poor self-repair capacity. If left untreated, unmatured degeneration will cause significant complications. Surgical intervention to repair cartilage may prevent progressive joint degeneration. A series of surgical techniques, including biological augmentation, microfracture and bone marrow stimulation, autologous chondrocyte implantation (ACI), and allogenic and autogenic chondral/osteochondral transplantation, have been used for various indications. However, the limited repairing capacity and the potential pitfalls of these techniques cannot be ignored. Increasing evidence has shown promising outcomes from ACI and cartilage transplantation. Nevertheless, the morbidity of autologous donor sites and limited resource of allogeneic bone have considerably restricted the wide application of these surgical techniques. Costal cartilage, which preserves permanent chondrocytes and the natural osteochondral junction, is an ideal candidate for the restoration of cartilage defects. Several in vitro and in vivo studies have shown good performance of costal cartilage transplantation. Although costal cartilage is a classic donor in plastic and cosmetic surgery, it is rarely used in skeletal cartilage restoration. In this review, we introduce the fundamental properties of costal cartilage and summarize costa-derived chondrocyte implantation and costal chondral/osteochondral transplantation. We will also discuss the pitfalls and pearls of costal cartilage transplantation. Costal chondral/osteochondral transplantation and costa-based chondrocytotherapy might be up-and-coming surgical techniques for recalcitrant cartilage lesions.
