Dr. Chen’s surgical technique for medial meniscus root repair:
An arthroscopic procedure performed to repair a meniscus that has torn away from its posterior horn attachment on the tibia. Two small incisions are made on the front of the knee. An arthroscopic camera and instruments are used to identify the tear and ensure it is amenable to repair. A third, very small, incision is made just below the knee and a specialized drill bit and guide are used to drill a small hole to the posterior horn attachment site. The tip of the drill bit flips to the side and reverse drills a socket in the tibia from inside the knee. Sutures are passed through the meniscus root then shuttled through the tunnel. This brings the torn meniscus in contact with a fresh bone bed to promote healing. The sutures are appropriately tightened and are secured on the bone using a plastic button.

Common Questions about Meniscus Root Repair
What is a meniscus root?
Each meniscus has two roots - an anterior and posterior root. The posterior root is the more commonly injured root. The roots are the most important structure that anchors the meniscus to the knee.
When do I need a meniscus root repair?
A traumatic root tear in a well preserved knee should be repaired to prevent premature future arthritis. A degenerative root tear in a knee showing arthritis should not be repaired.
How is a meniscus root repaired?
Sutures are placed into the meniscus root tissue. A tunnel is drilled into the bone. The sutures are pulled through the tunnel and anchored to the tibia with plastic anchors.
What is the rehabilitation after a root repair?
After root repair the patient is non weight bearing on crutches for four weeks. This is followed by physical therapy to return to normal activity.
