Comparing Meniscus Repair With and Without the BEAR Implant in Adults Aged 18 to 75

What this Trial Is About

Researchers are studying the use of the bridge-enhanced ACL repair BEAR implant, a collagen-based scaffold loaded with the patients own blood, to support healing after meniscus tears in the knee. This trial compares clinical outcomes and inflammation markers in the knee joint fluid between patients undergoing meniscus repair with or without the BEAR implant. The goal is to understand how this implant affects recovery in patients with isolated meniscal injuries. The study involves two groups of adult patients with meniscus injuries needing isolated repair. One group will receive standard arthroscopic meniscus repair, which involves suturing the torn meniscus fragments. The other group will have this repair plus insertion of the BEAR implant during surgery. The implant, made from sterilized bovine collagen and extracellular matrix, is placed through arthroscopic portals and is absorbed within 8 weeks, being replaced by new repair tissue. Participants will be followed for up to one year after their procedure. Researchers will assess knee function and pain using the International Knee Documentation Committee IKDC Subjective Knee Form, Lysholm Scale, and Visual Analogue Scale VAS at baseline and one year. They will also monitor the rate of repair failure during this time. The study is randomized and single-blinded, ensuring careful comparison of outcomes between the two groups.
