Bridge-Enhanced ACL Repair (BEAR) in Meniscus Repair
What this study is about
The bridge-enhanced ACL repair (BEAR) implant is a collagen-based scaffold loaded with whole blood. It is designed to promote healing in the setting of intraarticular knee pathology. This study would compare clinical outcomes and synovial fluid cytokine profiles in patients who undergo isolated meniscal repair with or without the BEAR implant.

The bridge-enhanced ACL repair (BEAR) implant is a collagen-based scaffold loaded with whole blood. It is designed to promote healing in the setting of intraarticular knee pathology. This study would compare clinical outcomes and synovial fluid cytokine profiles in patients who undergo isolated meniscal repair with or without the BEAR implant.
Interventions
PROCEDURE
Meniscal Repair Procedure
All meniscal repairs will be performed by the surgeons who are listed as investigators for the study. Meniscal repair consists of arthroscopic suturing of torn fragments. This takes approximately 20 minutes. In the interventional group, the BEAR implant will be inserted through preexistent arthroscopic portals after repair is complete. This will take an additional 2 minutes.
DEVICE
BEAR Implant
The BEAR Implant (22 mm in diameter and 45mm in length) is cylindrical in shape and comprised of collagen and extracellular matrix derived from bovine connective tissue, which has been cleaned, disinfected and processed by a proprietary manufacturing method. The implant has been terminally sterilized by electron-beam inadiation and is intended to be used with up to 10 ml of autologous blood drawn during the surgical implantation procedure. The BEAR Implant is resorbed within 8 weeks and replaced with a fibrovascular repair tissue.
Primary outcome measures
Change in International Knee Documentation Committee (IKDC) Subjective Knee Form Score
Time frame: Baseline, 1 Year Post-Procedure
10-item assessment of knee-related symptoms at the present moment and over the previous 4 weeks. Each item is rated according to presence of symptoms. The raw score is the sum of responses and is rescaled to a total score ranging from 0 points (lowest level of function or highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms).
Change in Lysholm Scale Score
Time frame: Baseline, 1 Year Post-Procedure
8-item assessment of knee-related activity and problems at the present moment. Each item is rated on a Likert-type scale. The total score is the sum of responses and ranges from 0 to 100, with higher scores indicating greater level of function/lower level of symptoms.
Change in Visual Analogue Scale (VAS) Score
Time frame: Baseline, 1 Year Post-Procedure
One-item assessment of pain on the current day. Pain is rated on a scale from 0 (no pain) to 10 (worst possible, unbearable, excruciating pain); the total score is the numerical rating.
Incidence of Repair Failure
Time frame: Up to 1 Year Post-Procedure
Instances of failure of the meniscal repair.

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.
