BACKGROUND: Graft selection and histological fate for anterior cruciate ligament reconstruction is a hot topic in the fields of reconstruction and repair of anterior cruciate ligament.OBJECTIVE: To review structure of anterior cruciate ligament and graft selection.METHODS: Articles were retrieved from Medline database with the key words of "Anterior cruciate ligament, implant,reconstruction" between January 1980 and January 2010. inclusion criteria: ① Reconstructive surgery of anterior cruciate ligament injury; ② graft selection of anterior cruciate ligament. Exclusion criteria: ① the old literatures; ② repetitive studies. A total of articles related to reconstruction of anterior cruciate ligament were retrieved, but 33 ones were included in the final analysis. The old, duplicated, and similar studies were excluded.RESULTS AND CONCLUSION: At present, the major therapy for anterior cruciate ligament injury includes arthroscopy and arthroscopy-assisted reconstruction. For clincal application, there are a lot of grafts, including autogenous grafts, allografts,heterologous allograft, biological materials, artificial materials and tissue engineering grafts. Autogenous semitendinosus tendon and gracilis tendon or autogenous bone-patellar tendon (middle 1/3)-bone (BPTB) are mainly used for anterior cruciate ligament reconstruction at home and abroad.

Objective To sum up a new surgical method to treat knee ankylosis with skeletal traction following arthrolysis. Methods Skeletal traction through supracondyle of femur or through patella was applied for 48 patients with knee ankylosis after dissection of both intra and extra articular adhesion and quadricepsplasty. Results The follow up period ranged from 3 to 36 months. The flexion angles of the knee joint increased 70?to 105?in 34 patients. Conclusion Skeletal traction following arthrolysis to treat knee ankylosis can prolong the length of quadriceps,increase the flexion angle of the knee joint step by step and facilitate early functional recovery after operation.
