Abstract:

BACKGROUND: Knee joint is the main weight loading joint of human body and the center part of human body motion. The physiologic structure and motion composition are very complex. Knee joint injury is common in sports and daily lift. Therefore, selection of appropriate knee joint biomaterials is critical for repair and functional reconstruction.
OBJECTIVE: To summarize performance and clinical application of knee biomaterials and analyze selection of biomaterials and correlation with biomechanics.
METHODS: A computer-based online search of PubMed, VIP and Wanfang database was performed for articles published between January 1980 and October 2011 regarding knee joint injury treatment and materials, with key words “knee; materials; mechanics” in English and Chinese. Finally, 27 articles were included.
RESULTS AND CONCLUSION: During knee regeneration or reconstruction or prosthesis replacement, ideal materials play important roles in treatment effects. The selection of materials and biomechanics are closely correlated. Study and development of materials with ideal biomechanics are important, and modification for the materials is also necessary.
