Secure tendon-bone integration is crucial for successful anterior cruciate ligament (ACL) reconstruction. Previous studies have applied different types of biomaterial or biomaterial combined with bone-growth factors to enhance tendon-bone integration. However, which approach is better remains controversial. This comparison evaluation could help identify a suitable composite biomaterial for osteointegration of grafted tendon. ⋯ Our results indicate that RBX seems to be a very good choice for accelerating tendon-bone integration, and CPCB also has a large potential ability to be used. However, these two composites still need to be modified, and we postulate that a combination of them would be more favourable for tendon osteointegration after ACL reconstruction than either composite used alone.
