Meniscus Tear
Conditions
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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Tegner activity score | 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. |
