Abstract
Introduction: Total meniscectomy can cause cartilage degeneration and osteoarthritis. The healing capacity of the meniscus is limited. Bioengineered meniscus can be a valid therapeutic option. Within the framework of the European Project MENISCUS, a pilot animal study was conducted to evaluate surgical technique, critical defect size, implant ingrowth and postoperative mobilization using a meniscus replacement device.
Materials and Method: Six sheep were operated on their right stifle joints. 3 sheep received a total meniscus replacement with a 3D biomaterial fixed with sutures. Additionally, controls without implant were operated. The sheep were sacrificed and evaluated clinically and histologically after 6 weeks.
Results: All implants showed excellent adhesion to the capsule and a good ingrowth at the periphery and the horns. Tissue formation was confirmed histologically.
Conclusions: Tissue ingrowth of the implant was demonstrated. The promising results concerning tissue formation and its meniscus like properties will have to be confirmed in future long-term studies.
