About this study
Official title: Safety and Early Clinical Performance of High-Purity Type I Collagen Augmentation in Arthroscopic Meniscal Repair: A Prospective Feasibility Study
This prospective, single-arm feasibility study evaluates the safety, procedural feasibility, and early clinical outcomes of High-Purity Type I Collagen used as an adjunct in arthroscopic meniscal repair. The study aims to generate preliminary clinical, functional, and imaging data to inform the design of a future randomized controlled trial.
Read the detailed description
Meniscal preservation is critical for long-term knee joint health, yet healing failure remains a concern, particularly in avascular zones. High-Purity Type I Collagen serves as a bioactive scaffold promoting cellular migration and early tissue integration. This study assesses early safety signals, feasibility metrics, patient-reported outcomes, and MRI-based healing characteristics following collagen-augmented meniscal repair.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
High-Purity Type I CollagenDevice
Standard arthroscopic meniscal repair performed using established techniques (inside-out, outside-in, or all-inside). High-Purity Type I Collagen mesh is trimmed and applied over or within the repair site and secured using sutures or fibrin sealant, according to intra-operative requirements.
| Study group | Role | What they receive |
|---|---|---|
| High-Purity Type I Collagen-Augmented Meniscal Repair | Experimental | Participants undergo standard arthroscopic meniscal repair augmented with High-Purity Type I Collagen applied at the repair site. Receives: Device: High-Purity Type I Collagen |
What is being measured
The primary outcome is the main question the study is designed to answer.
Safety of High-Purity Type I Collagen Augmentation
Incidence of device-related adverse events, including infection, inflammatory reactions, synovitis, or need for re-operationfollowing collagen-augmented meniscal repair.
Measured: From surgery to 2 months post-operatively
Secondary outcomes (4)
Pain Reduction Using Visual Analog Scale (VAS)
Change in patient-reported knee pain measured using the Visual Analog Scale. Pain intensity was assessed using a 10-point Visual Analog Scale (VAS) ranging from 0 to 10, where 0 represents no pain and 10 represents the worst imaginable pain. Lower scores indicate less pain and better clinical status, while higher scores indicate greater pain severity and worse symptoms.
Measured: Baseline, 6 weeks, and 8 weeks
Functional Outcome Using IKDC Subjective Knee Score
Change in knee function assessed using the International Knee Documentation Committee (IKDC) subjective knee score, a patient-reported outcome measure assessing symptoms, knee function, and ability to perform daily and sports activities. Scores range from 0 to 100, where 0 represents the worst possible knee function and 100 represents normal knee function without limitations. Higher scores indicate better knee function, and an increase in score represents clinical improvement.
Measured: Baseline and 2 months
Functional Outcome Using Lysholm Knee Score
Knee stability and functional performance were evaluated using the Lysholm Knee Scoring Scale, a validated questionnaire assessing pain, instability, swelling, limp, locking, and stair climbing ability. The total score ranges from 0 to 100, where higher scores indicate better knee function and fewer symptoms. A score of 100 represents optimal knee function, while lower scores indicate increasing levels of impairment. Therefore, an increase in Lysholm score represents clinical improvement.
Measured: Baseline and 2 months
Early Meniscal Healing on MRI
MRI-based assessment of meniscal integrity, signal intensity at the repair site, and presence of fluid clefts or displacement. Participants with non-interpretable or unavailable MRI were categorized as 'Not assessable'.
Measured: 2 months post-operatively

Questions about this trial
What is this clinical trial studying?
A study testing High-Purity Type I Collagen in people with Meniscus Tear and Knee Meniscus Injury, run by Adichunchanagiri Institute of Medical Sciences, B G Nagara at 1 site in India.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 8 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety of High-Purity Type I Collagen Augmentation (time frame: From surgery to 2 months post-operatively). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07352410, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2026.
