Meniscus Repair Techniques

Abstract

The menisci play a vital role in maintaining knee function and protecting the chondral surfaces. Acute and chronic tears are common injuries among both young athletes and older patients with early degenerative changes. The progression of physiological derangement and chondral injury after meniscus injury and meniscectomy have prompted interest in expanding meniscus repair techniques. Recent literature encourages an attempt at repair in tear patterns previously declared irreparable if the tissue quality allows. The orthopedic surgeon should understand the multitude of techniques available to them and be prepared to combine techniques to optimize the quality of their repair construct. While biological augmentation may show some promising early results, the quality of the current data precludes strong recommendations in their favor.

Effects of two suture methods under arthroscopy on isolated occult medial meniscocapsular separation

“…It might also be closely connected with the medial meniscus and the articular capsule, medial collateral ligament, posterior oblique ligament, and semimembranous muscle, resulting in fixation of the meniscus by femoral tibial clamp during sudden knee torsion, and the medial occult separation caused by the force traction of the semimembranous muscle-posterior oblique ligament-articular capsule [17]. Another part of our current IOMMCS cases presented other joint injuries, which might be the combined result of knee joint injuries at different stages and parts [18,19].…”

A gel microparticle-based self-thickening strategy for 3D printing high-modulus hydrogels skeleton cushioned with PNAGA hydrogel mimicking anisotropic mechanics of meniscus

“…Meniscus injury is the most common orthopedic disease [ 1 ]. Clinically, the total meniscectomy remains the preferred treatment for larger-sized and irreparable meniscal injuries; however, this can inevitably lead to disordered knee joint stability, articular cartilage wear, and even the progression of osteoarthritis (OA) [ 2 ]. To address this problem, meniscus substitutes have been developed, but most of them are homogeneous in structures, which fail to mimic the anisotropic structure and mechanical properties of native tissue [ [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] ].…”
