Repair of articular cartilage defects: part I. Basic Science of cartilage healing.Am J Orthop (Belle Mead NJ). 1999 Jan; 28(1):31-3.AJ
Articular cartilage injuries result in numerous clinical symptoms, such as pain and decreased functional levels. The limited reparative capabilities of hyaline cartilage results in the generation of repair tissue that lacks the structure and biomechanical properties of normal cartilage. Chondrocytes are unable to adequately proliferate, migrate, and synthesize high-quality repair tissue in response to blunt, superficial, or deep penetrating trauma. Extensive research has been conducted to understand the healing process and devise techniques that would enhance this response. Part I of this paper will discuss the basic science of cartilage repair. Part II, which will be published in the February issue, will present the treatment options.
