Costal Cartilage Grafting Techniques for Articular Repair
Summary
Costal cartilage grafting has emerged as a durable and biologically compatible option for restoration of damaged joint surfaces. Harvested from the patient’s own rib, costal cartilage offers a resilient matrix of chondrocytes and extracellular matrix that can withstand mechanical loading while integrating with surrounding tissues. Techniques range from simple interpositional grafts placed into small joint defects in the hand and wrist to more sophisticated constructs combining chondrocyte cultures with porous carriers for larger osteochondral lesions. The autologous nature of the graft minimises immunogenic risk, and its intrinsic capacity for neovascularisation supports long-term viability. Recent advances have focused on refining harvest methods to reduce donor-site morbidity, improving shaping and fixation through press-fit or customised scaffold support, and integrating cell-based approaches to regenerate hyaline cartilage rather than fibrocartilage. These innovations hold promise for addressing degenerative and traumatic joint conditions across the body, from carpometacarpal osteoarthritis to focal cartilage defects in larger articulations. By leveraging the structural and biological advantages of costal grafts, clinicians aim to restore joint congruity, preserve function and delay or avoid more invasive prosthetic replacement procedures.
