Abstract:

BACKGROUND: The biomechanical analysis of knee joint and knee joint ligament can prevent knee joint injury and is the basis of treating knee joint disease.
OBJECTIVE: To summarize the application progress of repair materials during knee joint injury reconstruction and biomechanical features of knee joint after repair.
METHODS: We retrieved China National Knowledge Infrastructure and PubMed database for relevant articles. The key words were “tissue engineering, articular cartilage, scaffold material, biomechanics”. We discussed biomechanical characteristics of knee joint after repair.
RESULTS AND CONCLUSION: Biomechanical studies verified that posterolateral structure of knee joint plays an important role in confining knee joint introversion, external rotation, antelocation and retrusion of tibia. Partial or complete breakage of knee joint ligament had poor effects on biomechanical characteristics of femoral medial condyle. Each ligament of knee joint combined with other ligaments and tissues reached mechanical balance. If a ligament was broken, the balance would be damaged, and the stress distribution of each ligament should be changed. The injury type and site of knee joint were varied. Repair and reconstituted materials and reconstituted manners were various. Finally, the biomechanical characteristics were also varied. The biomechanical functions of repair materials played an important role in knee joint moulding, healing process and functional recovery following transplantation.
