Effect of PRP Versus BMC in Anterior Cruciate Ligament Reconstruction

Summary

Anterior cruciate ligament (ACL) is an important stabilizer of knee during daily activity and exercise. The ruptured ACL need to be reconstructed by a new tendon graft which passed the bone tunnel and joint during operation. How to enhance the tendon graft to bone tunnel healing is critical important to prevent recurrent ligament laxity, avoid secondary osteoarthritis, and achieve early return to sports and work. Platelet Rich Plasma (PRP)，harvest from peripheral blood, is rich in multiple growth factors(i.e. VEGF, PDGD, TGFB, IGF, EGF) which help the injured tissue regeneration. Bone marrow stem cell has been demonstrated to enhance the injured tissue repair both in vitro and in vivo study. However, there is no prospective study in comparing the PRP and BMC to enhance interfacial healing between graft and bone tunnel in ACL reconstruction. Investigators hypothesize that the combination of PRP and BMC has synergetic effect in interfacial healing in ACL reconstruction. Aim of this study： To investigate the result of clinical functional scoring, MRI, and biomechanical study between PRP augmentation, PRP+BMC augmentation and traditional ACL reconstruction.
