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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

15 years to 45 years (Child, Adult)

Accepts Healthy Volunteers

No

  • Tearing affecting: only 2/3 central (= avascular zone) over more than 1 cm OR extending from the peripheral third (= vascularized area) within the avascular zone over more than 1 cm. In this case, preservation of the peripheral third over a width of at least 4 mm from the capsule;
  • Single or multiple tears.

Exclusion Criteria:

  • Meniscal tears that can not be sutured, reduced / approximated
  • Tear creating a meniscal root avulsion
  • Partial meniscal tears

  • Mechanical axis (varus / valgus) ≥ 2 °
  • Untreated ligament deficiency
  • Osteotomy and / or concomitant ligament reconstruction, with the exception of ACL reconstruction.
  • Compromised general health condition (score ASA score> 2)
  • BMI ≥30
  • Active smoking, drug use
  • Allergy to porcine collagen

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
