Bone-Tendon-Bone (BTB) Grafts for Anterior Cruciate Ligament (ACL) Reconstruction
摘要
The Bone-Patellar Tendon-Bone (BPTB) autograft has long been favored in anterior cruciate ligament (ACL) reconstruction for its robust bone-to-bone healing and enhanced knee stability. However, recent trends have seen a shift toward alternative graft types due to concerns such as kneeling pain and patellar fracture. Despite this, the BPTB graft remains popular, especially for young, active individuals and in revision surgeries, where its structural robustness is advantageous. Surgical techniques for BPTB graft harvesting and preparation are well-established, emphasizing meticulous attention to detail to mitigate complications like graft-tunnel mismatch and anterior knee pain. While BPTB grafts offer benefits such as reduced risk of residual laxity and faster return to sport, concerns about donor site morbidity persist. Strategies to minimize such issues include precise surgical techniques and tailored rehabilitation protocols. Evaluation of BPTB graft outcomes reveals favorable results in terms of reduced residual laxity and high rates of return to preinjury activity levels. Ultimately, while the BPTB graft presents certain challenges, its advantages make it a valuable option for ACL reconstruction, particularly in young, active patients engaged in high-demand sports.
