Review of articular cartilage repair techniques and their application in the horse

Equine Veterinary Journal, EarlyView.
Abstract Articular cartilage lesions represent a significant career‐limiting problem in athletic horses. A healthy articular cartilage surface is vital for optimal joint function, and defects can result in irreversible degenerative changes. Successful treatment of cartilage lesions remains a long‐standing challenge for orthopaedic surgeons, prompting ...
