Abstract:
BACKGROUND: Anterior cruciate ligament reconstruction is the major treatment for anterior cruciate ligament injury. Studies on anterior cruciate ligament reconstruction with hamstring tendons developed rapidly. OBJECTIVE: To summarize anatomy, biodynamics and surgery approaches of anterior cruciate ligament, and the progress of anterior cruciate ligament reconstruction with hamstring tendons. RETRIEVAL STRATEGY: Pubmed database was undertaken to identify relevant articles on anterior cruciate ligament reconstruction with hamstring tendons published from January 1990 to October 2007 with the key words of "anterior cruciate ligament, hamstring tendons, reconstruction, tendon regeneration, bone tunnel enlargement" in English. Ninety-two articles were selected primarily, and checked by reading titles and abstracts. Inclusive criteria: articles on anterior cruciate ligament reconstruction with hamstring tendons were included. Excusive criteria: articles with different aims and repetitive contents were excluded. Totally 42 articles were included, of which 2 articles were on animals, 2 articles on system evaluation/Meta analysis and 38 articles on clinical research. LITERATURE EVALUATION: Of them, 22 articles were on anatomy, biodynamics, surgery approaches and clinical results of anterior cruciate ligament, 9 on bone tunnel enlargement of anterior cruciate ligament after reconstruction and 11 on regeneration of hamstring tendons after harvest. DATA SYNTHESIS: With the deep understanding of double-bundle dissection and biodynamics of anterior cruciate ligament and bad control of single-bundle reconstruction on rotary stability, double-bundle anterior cruciate ligament reconstruction with hamstring tendons has become the major treatment. Bone tunnel enlargement of anterior cruciate ligament after reconstruction is multifactorial process of biology and biodynamics, possibly resulting in reduction in primary stability after reconstruction and severe problems in graft fixation in revision surgery. Most hamstring tendons (first selected graft of double-bundle anterior cruciate ligament reconstruction) can regenerate, and partially recover its function, which determined its foundation for anterior cruciate ligament reconstruction used by orthopedists. Bone tunnel enlargement of anterior cruciate ligament after reconstruction still deserves further studies. CONCLUSION: Double-bundle dissection and biodynamics of anterior cruciate ligament lay the foundation for improving surgery scheme. Double-bundle anterior cruciate ligament reconstruction can better control rotary stability of knee joint.
