Not Applicable

Conditions
Meniscus Lesion
Interventions
Procedure: suturing meniscal
Procedure: suturing meniscal augmented
Registration Number
NCT03968029

Brief Summary

This study will compare meniscal healing of non-vascularised area augmented or not by bone marrow injected under a protective collagen membrane (meniscal wrapping)

Detailed Description

Historically, meniscus was considered as none essential for knee joint, and its removal by meniscectomy was the first-line treatment. Many studies have shown a negative progress towards osteoarthritis after meniscus ablation. This approach has gradually changed to preserve this meniscal capital, making way for new treatments as sutures. However the vascular organization of the meniscus is crucial for its cure. The healing potential of lesions in the meniscus non-vascularised aera is considered insufficient, and are often treated by a partial meniscectomy, resulting in a high risk of osteoarthritis. It appears therefore necessary to develop new strategies, as meniscal wrapping, to preserve meniscus presenting this type of damage.

  • Cartilage damage in the compartment> grade 2 (ICRS classification)
  • Mechanical axis (varus / valgus) ≥ 2 °
  • Untreated ligament deficiency
  • Osteotomy and / or concomitant ligament reconstruction, with the exception of ACL reconstruction.
