View original scientific description
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.
Interventions
BIOLOGICAL
Concentrated Bone Marrow Aspirate Injection
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.
PROCEDURE
Sham Incision
A 2 mm sham incision will be made in the anatomical site where bone marrow would be harvested.
PROCEDURE
Revision Anterior Cruciate Ligament Reconstruction
This is the standard-of-care surgical procedure.
Primary outcome measures
Change from baseline in patient reported knee pain
Time frame: Baseline, 6 weeks, 6 months, 12 months and 24 months post-operative
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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
