Outcomes of Meniscus Root Repair Using a Transtibial Pullout Technique

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03037242
Recruitment Status : Active, not recruiting

Brief Summary:
The results of this study will optimize the care for patients with a meniscus root tear. Surgeons will be able to determine if MRR (meniscus root repair) with transtibial pullout technique is an effective treatment and will identify potential risk factors for poor clinical outcomes. In addition, investigators will determine if MRR is successful in delaying the radiographic progression of arthritis in the involved compartment.

Condition or disease Intervention/treatment Phase
Meniscus Tear Procedure: Transtibial pullout technique Not Applicable

Detailed Description:

The loss of attachment at the root of the meniscus impairs the ability to maintain hoop strain when the tibiofemoral joint is loaded. This loss of hoop strain is responsible for the increased pressure on the articular cartilage.

This new awareness has prompted surgeons to consider surgical repair for treatment of meniscal root avulsions. Despite this recent focus on results of surgical repair, prospective studies are lacking, and the optimal surgical indications and technique have not been optimized.

Arm Intervention/treatment
Transtibial pullout technique
Evaluation of the clinical and radiographic outcomes for patients undergoing a meniscus root repair (MRR) using a transtibial pullout technique.
Procedure: Transtibial pullout technique
Evaluating radographs

Primary Outcome Measures :
  1. Change in Tegner activity score [ Time Frame: baseline, 2 years ]

    Tegner activity level scale is a graduated list of activities of daily living, recreation, and competitive sports. The patient is asked to select the level of participation that best describes their current level of activity and that before injury. The score varies from 0-10.

    A score of 0 represents sick leave or disability pension because of knee problems, whereas a score of 10 corresponds to participation in national and international elite competitive sports >6 score can only be achieved if the person participates in recreational or competitive sport.
