Clinical and Instrumental Assessment of Meniscal ROOT Tears Treated Through Suture to the Posterior Cruciate Ligament

Condition(s) studied

Study summary

The menisci are crucial for knee stability and functionality. Composed of fibrocartilaginous structure, they have an anatomical and biomechanical arrangement that makes them essential for load transmission and the prevention of osteoarthritis. Meniscal root lesions, known as "ROOT tears," compromise their protective function on the cartilage, leading to increased contact pressures between the tibia and femur and, over time, the development of osteoarthritis. Early diagnosis of these lesions is difficult and often the first detection is incidental. The subsequent challenges are significant due to a lack of pre-operative planning. A possible solution is a surgical technique involving arthroscopic suture of the posterior meniscal root along with the posterior cruciate ligament. This procedure does not require pre-operative planning and is applicable even in cases of incidental diagnosis.

Eligibility

Primary outcome measure(s)

• RMN — 24 months after surgery
  The 3 Tesla MRI is the diagnostic test of choice used in common clinical practice to evaluate the healing of these lesions at 1 and 2 years of follow-up. The measured parameter is meniscal extrusion. The measurement is taken in millimeters at the coronal sections visualizing the medial collateral ligament, from the capsular margin of the body to the outer profile of the tibial plateau. The "ghost sign" and tibial plateau edema will also be looked for. The main limitation of MRI is related to the fact that it is performed non-weight-bearing, with the patient in a supine position.
