Brief Summary
The goal of this pilot randomized clinical trial is to look into the efficacy of concentrated bone marrow aspirate (cBMA) in improving post traumatic osteoarthritis (PTOA) symptoms in patients undergoing revision anterior cruciate ligament reconstruction surgery. The main questions it aims to answer are whether clinical outcomes, such as pain, are improved in patients who get cBMA with surgery, if there is a change in circulating markers of inflammation and what part of the cellular and molecular composition of cBMA may explain its effects.

Outcome Measures
Primary Outcomes (1)
Change from baseline in patient reported knee pain
The primary outcome measured for this study will be postoperative knee pain. This will be achieved using the Knee Injury and Osteoarthritis Outcome Score (KOOS) standardized questionnaire, which will be electronically delivered to participants at baseline and at 6-weeks, 6-months, 12-months and 24-months postoperatively. This questionnaire measures 42 items in a Likert scale for 5 different dimensions: pain, other symptoms, activities of daily living, function in sports and recreation and knee-related quality of life. The questionnaire is scored as a percentage from 0 to 100, with 0 representing extreme knee problems and 100 indicating no knee related symptoms, and therefore better outcomes.
Baseline, 6 weeks, 6 months, 12 months and 24 months post-operative
Secondary Outcomes (4)
Expression of local inflammatory biomarkers
Baseline and 6 weeks post-operative
Concentration of circulating inflammatory biomarkers
Baseline, 6 weeks and 12 months post-operative
Change from baseline in cartilage morphology
Baseline, 12 months post-operative
Change from baseline in articular cartilage relative proteoglycan content and collagen fibril organization
Baseline, 12 months postoperative
Study Arms (2)
Investigational Arm
EXPERIMENTALPatients undergoing revision anterior cruciate ligament reconstruction surgery will get an intraoperative injection of concentrated bone marrow aspirate (cBMA).
Control Arm
SHAM COMPARATORPatients undergoing revision anterior cruciate ligament reconstruction surgery will get a sham incision in lieu of bone marrow harvesting.
Interventions
Intraoperatively, bone marrow will be harvested from the iliac crest with a commercial kit, it will then be prepared via centrifugation and an injection of the resulting concentrated product (cBMA) will be administered in the operative knee. cBMA is an autologous biologic product.
A 2 mm sham incision will be made in the anatomical site where bone marrow would be harvested.
This is the standard-of-care surgical procedure.
Eligibility Criteria
You may qualify if:
- Males and Females
- Age 18 to 55
- Previous unilateral ACLR (Anterior Cruciate Ligament Reconstruction) within the last 5 years, and identified as having experienced failure of the primary ACLR
- Scheduled to have a revision ACLR surgery, with any graft type (including patellar tendon, hamstring, quad or allograft)
- Able to complete all study procedures and participate in a standardized physical therapy program
You may not qualify if:
- History of inflammatory arthritis or joint sepsis
- Prior or concurrent total or sub-total meniscectomy
- Prior or present avascular necrosis of the index knee
- Oral or intra-articular corticosteroid injection within 3 months
- Hyaluronic acid or PRP (Platelet-Rich Plasma) injection within 6 months
- Use of duloxetine, doxycycline, indomethacin, glucosamine and/or chondroitin (ongoing or within 2 months)
- Any clinical or laboratory abnormality greater than grade 3 CTCAE, which in the view of the investigator, will compromise the participant's safety.
- Planned arthroplasty in the index knee
