Clinical Trial Summary

It is estimated that 48 out of 10,000 people, in the United States, will tear their anterior cruciate ligament (ACL) annually and undergo ACL reconstruction (ACLR). Surgeons have several graft options, surgical techniques, and fixation methods to consider when planning how to reconstruct a patient's ACL. Graft options vary greatly and include allografts and autografts with good evidence that are good choices. Further, autografts include several different specific grafts including; bone-patellar tendon-bone (BPTB), hamstring tendons, and quadriceps tendon. There is no clear consensus on which graft type is superior, as each graft has associated positives and negatives. Historically, autologous BPTB grafts have been the preferred choice of surgeons given its ability to restore rotational stability for the knee, the robust healing with direct bone-to-bone contact at both ends of the graft, and low failure rates. However, there are drawbacks to ACLR using a BPTB graft. Complications following BPTB graft harvesting include patella fractures, patellar tendon ruptures, increased risk of patellofemoral osteoarthritis, lack of terminal extension, and donor-site morbidity. The majority of these complications are associated with low-risk rates, except for donor-site morbidity which may be prevalent in 37-51% of BPTB graft patients. Donor-site pain can manifest as anterior knee, patellofemoral pain, loss of sensory input, or discomfort with kneeling and can negatively influence subjective as well as objective measures of knee function. Filling bony defects with bone graft is a procedure that is commonly conducted within orthopedics. However, its use in treating the bony defects caused during BPTB graft harvesting is less common as patella and tibial harvest sites are routinely left unfilled. Significant methodological differences in treatment interventions for the patella harvest site, the tibial harvest site, or both and conflicting results have made it difficult to determine if these treatments have clinical utility. To the best of the investigators' knowledge, there has been no investigation looking at the incidence of donor site morbidity treated with autologous bone grafting of the harvest sites. Therefore, the purpose of this study is to determine if filling the harvest site defect is associated with a lower rate of donor site morbidity and better patient reported functional outcomes compared to patients whose harvest site remains unfilled. The purpose of this study is to compare the rate of donor site morbidity between patients who have their harvest sites bone grafted with autologous bone (BG) and those whose harvest sites remain unfilled (nBG).

Primary	Visual Analog Scale	The Visual Analog Scale (VAS) is a 10-cm line that allows subjects to visually report their pain between "no pain" (0 cm) on the left and "constant pain" (10 cm) on the right. Patients will be asked to complete the VAS with the prompt, "Please indicate the amount of pain you are feeling right now in the front of your knee." It is considered a worse outcome the closer the patient marks to the "constant pain" on the right of the scale.	pre-op

Secondary	PROMIS-10	The Patient-Reported Outcomes Measurement Information System-10 (PROMIS-10) will be used to assess global quality of health. The PROMIS Global-10 is a 10-item patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. The results of the questions are used to calculate two summary scores: a Global Physical Health Score and a Global Mental Health score. These scores are then standardized to the general population, using the "T-Score". The average "T-Score" for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient.	pre-op

Secondary	Knee Injury and Osteoarthritis Outcome Score for Patellofemoral Pain (KOOS-PF)	The Knee Injury and Osteoarthritis Outcome Score for Patellofemoral Pain (KOOS-PF) will be used to assess functional limitations due to patellofemoral joint pain. This will be necessary to evaluate as the BPBT graft is harvested from the patellar and may affect the function of the patellofemoral joint. KOOS-PF is an 11 item patient reported outcome, with each item rated as Never/none = 0, Monthly/mild = 1, Weekly/moderate = 2, Daily/severe = 3, Always/extreme = 4. The mean score is calculated for the 11 items, and divided by the maximum possible score for each item (i.e. 4). Traditionally in orthopedics, 100 indicates no problems and 0 indicates extreme problems. The normalized score is transformed to meet this standard.	pre-op
