Evidence-Based Approach to Orthobiologics for Osteoarthritis and Other Joint Disorders.

Osteoarthritis and cartilage lesions are a major cause of functional limitations which is why the goal of biological treatment is to preserve the native joint to delay the onset of OA. As a result of improvements in surgical techniques and technology, treatment options are more and more available, allowing the treatment of a whole range of injuries, from minor to extensive lesions both acute and chronic. In chondral lesion treatment, restoring hyaline-like cartilage provides improved durability of repaired tissue and desirable wear characteristics. Biological cell-based cartilage restoration treatment was developed to address the need for the long-term viability of repaired tissue. These procedures provide a reliable source of chondrocytes, whether directly or through the differentiation of multipotent precursor cells, capable of producing hyaline-like cartilage, with the minimal formation of fibrocartilage tissue. However, if arthritic changes begin biological therapies offer possibilities to delay. This chapter aims to discuss and give insights into these regenerative, joint preservation techniques for cartilage treatment and possible biological treatment in OA.
