The Effect of Bone-void Filler on Anterior Knee Pain Following ACL Reconstruction

The Effect of Bone-void Filler on Anterior Knee Pain Following ACL Reconstruction With Bone-Patellar Tendon Bone Autograft

One of the common complaints after ACLR with BPTB autograft anterior knee pain. It is thought that this may be due to harvesting the patellar tendon for graft use. Specifically, this may be due to the bone defect that is left after graft harvesting. There is currently no consensus on a gold standard for treating the bone defect with surgeons using multiple commercially available bone void fillers as well as autologous bone graft in standard practice.

The purpose of the proposed study is to evaluate the effect bone-void filler on anterior knee pain following ACL reconstruction BPTB autograft.
