Clinical Data

The Menaflex™ collagen meniscus implant (formerly CMI^®) product has been the subject of numerous clinical studies¹, scientific presentations, and published papers.  The results of the clinical studies show the Menaflex scaffold supports growth of new tissue, reduces the likelihood of additional meniscus surgery, improves patient satisfaction and activity levels, and is safe.

The Menaflex procedure facilitates the growth of the patient’s own tissue.

• Meniscus does not regenerate on its own.
• The U.S. multicenter clinical trial reported a 97% tissue increase in chronic patients.
• Tissue growth was documented by re-look arthroscopy one year following the procedure.
• The new tissue has longevity based on feasibility study patients’ re-look procedure at more than 5 years.

The re-operation rate for chronic patients was nearly 3 times lower for Menaflex patients after four years.

Menaflex patients with chronic meniscus injuries reported higher satisfaction levels.

• Satisfaction was statistically correlated with pain, Lysholm, and Tegner activity scores.
• Patient satisfaction reflects each patient’s desired outcome.

Within the chronic group, Menaflex patients had a significant increase in return to activity.
The Menaflex procedure is safe.

• There were no unanticipated adverse events associated with the device.
• Re-look biopsies indicate no adverse histological effect.
• Immunologic studies indicate no significant immune response.
