後方半月板根部修復のための視覚化改善技術

Meniscal roots are critical components of the menisci that ensure joint congruity and allow the meniscus to serve its biomechanical function of converting axial loads into hoop stresses. Repairing the meniscal root is critical to prevent accelerated knee joint damage and progression to osteoarthritis, but access to the posterior roots, in particular, can be challenging. Regardless of the technique utilized, adequate visualization and access to the posterior roots is critical to perform an appropriate repair. While percutaneous release of the medial collateral ligament has been demonstrated in previous technical notes and has been shown not to negatively affect outcomes for patients, other methods for improving access and visualization to the posterior knee, such as performing a reverse notchplasty, or a resection of the medial tibial spine are also useful techniques. In this technical note, we present the senior author's combined techniques for improving visualization of the posterior meniscal root when performing a medial meniscus posterior root repair.
