Meniscal Root Tears: Evaluation Using an Ultrahigh MRI

Knee Injuries Clinical Trial

Official title: Meniscal Root Tears: Evaluating Meniscal Extrusion After Root Repair With and Without Transtibial Peripheral Stabilization Sutures Using Ultrahigh Magnetic Fields: A Randomized Controlled Trial

Status Recruiting

Clinical Trial Summary

Meniscal root tears have been recently recognized to be one of the most common causes for the progression of arthritis in relatively young patients. The purpose of the study will be to assess if the addition of a transtibial peripheral stabilization suture helps to decrease both meniscal extrusion and if it helps to decrease the progression of osteoarthritis of the medial compartment of the knee in the early timeframe postoperatively.

Clinical Trial Description

Studies have reported that the most common reason why patients require total knee arthroplasty before the age of 60 is a neglected or meniscectomized medial meniscus root tear. Overall, it has been noted that meniscal root repairs are cost effective and that the outcomes of meniscus root repairs are demonstrating patients have a significant improvement of their preoperative symptoms up to several years after surgery. Because most centers have only been preforming meniscus root repairs over the last five to ten years, we are now starting to recognize why some of the repairs do not function as well as others. The number one reason appears to be due to a postoperative meniscus extrusion. Meniscus extrusion has been seen in up to 50% of postoperative patients, and biomechanical studies have demonstrated that the cushioning effect of the medial meniscus does not function as well when there is a meniscus extrusion present. New biomechanical studies have demonstrated that the addition of a peripheral stabilization suture at the far posteromedial aspect of the medial tibial plateau helps to hold the meniscus better in the joint and that it also results in a significant decrease in load on the medial compartment. However, clinical studies are lacking to date as to whether a peripheral stabilization suture may or may not improve the protected function of the medial meniscus, decreased extrusion, and potentially lead to a less amount of progression of osteoarthritis in the medial compartment of the knee.

Therefore, this study strives to both assess the ability of a meniscus root repair to slow down the progression of arthritis of the medial compartment of patients with a 7-Tesla MRI scanner and also to concurrently assess the ability of the usage of a transtibial peripheral stabilization suture to decrease or eliminate meniscal extrusion. The importance of this study is that if the peripheral stabilization suture is noted to both decrease the progression of arthritis and also to decrease the meniscus extrusion, it will be a significant step forward in the treatment of these complex meniscal tears. ;
