Summary
This will be a prospective study for patients undergoing ACL reconstruction using bone-patella-tendon-bone graft, hamstring graft or achilles allograft. Each group will have ACL reconstruction with fixation using bioabsorbable interference screws on the femoral and tibial side. Patients will be evaluated on the day of surgery, 6, 12, 24, 52 and 104 weeks post-operatively. Evaluations will include pre-operative regional and standard bone mineral density measurements, post-operative MRI evaluation of tunnel dimensions and bone-tendon interface, radiographic evaluation of tunnel dimensions and routine clinical follow-up. Twenty patients will be enrolled in each group.
Inclusion/Exclusion Criteria
Inclusion Criteria
Individuals within the age of 18 to 55 who are diagnosed with anterior cruciate insufficiency and have decided to undergo ACL reconstruction using autogenous graft will be included in the study.
Exclusion Criteria
Individuals that have previous knee surgeries, multi-ligament injuries, systemic ligament disorders such as Ehlos Danlos syndrome or connective tissue disorders will be excluded from the study. Individuals who are pregnant or expect to be pregnant during the course of the study or who are especially concerned with X-ray exposure should also be excluded.
