Clinical Trial Summary

A prospective study, with outcomes including re-rupture rate and return to sport will be collected following ACL reconstruction. In keeping with the surgeon's standard practice, patients 24 years and under that are skeletally mature, will receive a quad tendon autograft; patients 25 years of age and over will receive an allograft All-Inside ACL reconstruction. These two cohorts will then be randomized into two groups, one with bone marrow/DBM and InternalBrace augmentation, and one without. The study procedures will involve use of x-rays, MRI, CT scan, and surveys at varying time points to assess radiographic, imaging and clinical outcomes.

Description:

Graft re-rupture is one of the major complications and causes of reoperation after anterior cruciate ligament (ACL) reconstruction. This is more common in younger athletes. Based on the recent literature the rate of graft re-rupture is about 6-11%. Even with newer techniques and different types of grafts the re-rupture rates and return to play have not improved significantly. Athletes younger than 25 years old have been found to have a 23% risk of secondary ACL injury either on the contralateral or ipsilateral side after an ACL reconstruction. Therefore, there is a direct need to improve the outcomes of ACL reconstruction especially in younger athletes. This could be accomplished with earlier biologic incorporation of the graft and further protecting the graft during the early postoperative period. Quad tendon all-inside reconstruction is a reproducible technique for younger athletes receiving surgery. For patients over the age of 22, allograft is commonly used. Recently autogenous bone marrow aspirate has shown superior radiographic incorporation when used for osteochondral allograft transplantation in the knee. The bone marrow aspirate has also shown the presence of similar mesenchymal stem cell concentrations when harvested from the proximal tibia compared to when harvested from the iliac crest; providing a useful and safe alternative during knee surgery. This bone marrow aspirate can be combined with demineralized bone matrix (DBM) as a medium for incorporation into a femoral and tibial tunnel during reconstruction of an ACL. Recently, as an augment to the procedure, an ultrahigh-molecular-weight polyethylene/polyester suture tape was used as an InternalBrace for an ACL allograft reconstruction and found to be safe and effective. The hypothesis of this study is that the combination of the InternalBrace and biologic addition of autogenous bone marrow aspirate may provide improved functional outcomes, and reduced failure rates after ACL reconstruction.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in X rays	AP and lateral radiographs of all patients included in the study will be obtained and assessed for changes over the study duration at specified time periods	6 months, 1 year, and 2 years
Primary	Changes in International Knee Documentation score	Measures 3 categories: symptoms, sports activity, and knee function with a sum total 0-100 with 100 score having highest functional state and 0 low functioning.	Pre-Op, 2 weeks, 6 weeks, 12 weeks, 6 months, 1 and 2 years post-operatively
Primary	Changes in Visual analog pain scale	High score 10 means high pain, low score 1 means low pain	Pre-Op, 2 weeks, 6 weeks, 12 weeks, 6 months, 1 and 2 years post-operatively
Primary	Change in Knee Injury and Osteoarthritis Outcome (KOOS) Scores	five patient-relevant dimensions are scored separately: Pain (nine items); Symptoms (seven items); ADL Function (17 items); Sport and Recreation Function (five items); Quality of Life (four items). A Likert scale is used and all items have five possible answer options scored from 0 (No problems) to 4 (Extreme problems) and each of the five scores is calculated as the sum of the items included. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems	6 months, 1 and 2 years post-operatively
Primary	Change in THE VETERANS RAND 12 ITEM HEALTH SURVEY	patient-reported global health measure that is used to assess a patient's overall perspective of their health. seven different health domains: general health perceptions, physical functioning, role limitations due to physical and emotional problems, bodily pain, energy/fatigue levels, social functioning and mental health. Answers are summarized into two scores, a Physical Component Score (PCS) and a Mental Component Score (MCS) which then provides an important contrast between the respondents physical and psychological health status. results of the VR-12 are summarized as two scores - a Mental Component Score (MCS) and a Physical Component Score (PCS). The scores may be reported as Z-scores (difference compared to the population average, measured in standard deviations). The United States population average PCS and MCS are both 50 points.	6 months, 1 and 2 years post-operatively
Primary	Change in LYSHOLM KNEE QUESTIONNAIRE	patient-reported instrument that consists of subscales for pain, instability, locking, swelling, limp, stair climbing, squatting, and the need for support. Scores range from 0 (worse disability) to 100 (less disability).	6 months, 1 and 2 years post-operatively
Primary	Change in MARX ACTIVITY SCALE FORM	MARX focuses on four activity points: running, deceleration, cutting (changing directions while running), and pivoting. Patients are asked to indicate approximately how many times in the past 12 months they performed each of these activities while at their healthiest and most active state. The four knee functions are rated on a 5-point scale of frequency and scores are added up to a maximum of 16 points with a higher score indicating more frequent participation.	6 months, 1 and 2 years post-operatively
Primary	Return to play	We will assess the time it takes from date of ACl reconstruction until the patient returs to sporting activiy	Until study completion, average of 1 year
Primary	graft re-rupture rate	We will assess patients for incidence of graft rerupture rate during rehab or after return to play	Until study completion, average of 1 year
Primary	MRI	MIR scans will be performed first 6 patients in each group will receive MRIs of the knee to visualize graft maturation.	12 weeks post op
Primary	CT scan of operative knee	At six (6) months, the first 6 patients in each group will receive CT scans of the knee to assess tunnel widening	6 months post op
