Researchers are evaluating the safety and effectiveness of AM3101 in helping meniscal repair and reducing complications related to failed meniscal repairs. This is a prospective, randomized, controlled, double-blinded clinical trial conducted across multiple centers. The study compares AM3101 with a saline placebo in patients aged 18 to 40 who have meniscus tears, with or without ACL injuries. Participants receive an injection of either AM3101 or a saline solution following meniscal repair surgery. The study groups include one treated with the AM3101 injection and the other with the saline placebo. The primary goal is to assess meniscal healing by MRI at 12 months post-injection and to monitor the safety by tracking adverse events compared to the placebo group. During the study, participants will undergo MRI scans at 12 months to evaluate meniscal tissue integrity. Researchers will also assess adverse events and compare functional outcomes between groups. Participants must comply with study procedures and visit schedules, which include safety monitoring and follow-up visits over the course of one year. The overall participation duration is at least 12 months.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | Meniscal Repair + AM3101 | Meniscal Repair + Saline Placebo |
|---|---|---|
| What it is | Meniscal repair surgery with injection of AM3101, an investigational drug product intended to promote healing, given during the repair procedure. | Meniscal repair surgery with injection of saline placebo (0.9% sodium chloride), given during the repair procedure. |
| Primary use | To evaluate if adding AM3101 to meniscal repair improves tissue healing compared to standard repair. | Serves as the control group for comparison, with standard meniscal repair and placebo injection. |
| How it is given/performed | AM3101 is injected directly at the time of surgical meniscus repair. | Saline placebo (0.9% sodium chloride) is injected during the surgical meniscal repair in the same manner as AM3101. |
| Evidence status | Ongoing clinical investigation; published results for AM3101 in meniscal repair are not yet established. | Meniscal repair is supported by published evidence as an effective method for suitable meniscal tears. Saline acts only as trial placebo and does not influence healing. |
| Important limitations | Long-term safety and benefit of AM3101 in humans has not been determined. The trial excludes patients with certain comorbidities, prior knee surgeries, or who cannot comply with follow-up. | Repair success depends on tear pattern, patient factors, and rehabilitation. Systematic reviews note risk of incomplete healing or re-tear; strict trial eligibility may not reflect all practice cases. |
