Much of this is of poor quality and of a low evidence base. We review and summarise the literature looking at the four main classes of grafts used in ACL reconstruction; bone-patella tendon-bone, hamstrings, allograft and synthetic grafts. Each graft has the evidence for its use reviewed and then compared, where possible, to the others. We conclude that although there is no clear "best" graft, there are clear differences between the differing graft choices. Surgeon's need to be aware of the evidence behind these differences, in order to have appropriate discussions with their patients, so as to come to an informed choice of graft type to best suit each individual patient and their requirements.展开更多

Methods: From November 1999 to November 2003, the injured ACL and PCL of 11 patients were fixated with compressed screws and reconstructed under arthroscopy with the bone-patellar tendon-bone treated with deep hypothermia and γ radiation. At the same time, 2 patients were treated with medial collateral ligament (MCL) reconstruction, 3 with lateral collateral ligament (LCL) reconstruction, 1 with meniscus suture and 4 with whole or partial resection. Results: All patients were followed up for 12-26 months (average 16.5 months). The Lysholm score method was employed to evaluate the knee function. The average preoperative score was 45.3 and the postoperative score was 86.4. Anterior drawer test (ADT) was positive in 11 knees preoperatively and feeble positive in one knee postoperatively. Lachman test was positive in 11 knees preoperatively and in one postoperatively, and feebly positive in two postoperatively. Posterior drawer test was positive in 11 knees preoperatively and feebly positive in 2 postoperatively. There were 2 knees with tolerable pain and 2 with knee flexion of 5°-20°. Conclusions: As for simultaneous reconstruction of ACL and PCL under arthroscopy, allogeneic bone-patellar tendon-bone can not only avoid injury and complication caused by autografting, but also help rehabilitation of the knee function.展开更多
