Inclusion criteria
* Ages 18-50 * Patients who underwent primary ACL reconstruction performed by one of the study investigators at least 5 years ago * Isolated ACL tear * Type of graft used was bone-patellar tendon-bone autograft * Type of screw used to attach graft to the tibia and/or femur was a BioComposite interference screws (Arthrex, Inc.) * No degenerative joint disease on preoperative X-rays (\> 50% joint space loss, presence of osteophytes)
Exclusion criteria
* Revision ACL reconstructions * Types of grafts other than bone-patellar tendon-bone autograft were used * ACL tear with concomitant pathology * Degenerative joint disease on preoperative X-ray (\> 50% joint space loss, presence of osteophytes) * Metal or other types of bioabsorbable screws other than BioComposite interference screws (Arthrex, Inc.) were used * ACL reconstruction performed less than 5 years ago * Pregnancy * Greater than Grade 2 laxity of other ligaments * No additional fixation
