Cartilage repair procedures: clinical approach and decision making.

Articular cartilage lesions present a clinical challenge, but treatment options for these lesions are changing and expanding. The size of the lesion, the physical demands of the patient, and treatment history all are important factors to consider when selecting a surgical approach. It is important for the surgeon to understand the physiology of the selected cartilage repair method and to be aware of its effects on the postoperative rehabilitation program. Attention to surgical technique and selection of the most appropriate rehabilitation protocol will provide patients with the best chance of optimal results.
