Medial Meniscus Posterior Root Tear: A Comprehensive Review
Damage to the medial meniscus root, for example by a complete radial tear, destroys the ability of the knee to withstand hoop strain, resulting in contact pressure increases and kinematic alterations. For these reasons, several techniques have been developed to repair the medial meniscus posterior root tear (MMPRT), many of which have shown complete healing of the repaired MMPRT. However, effor...
متن کاملMeniscal Extrusion Progresses Shortly after the Medial Meniscus Posterior Root Tear
Purpose Medial meniscus posterior root tears (MMPRT) induce medial meniscus extrusion (MME). However, the time-dependent extent of MME in patients suffering from the MMPRT remains unclear. This study evaluated the extent of MME after painful popping events that occurred at the onset of the MMPRT. Materials and Methods Thirty-five patients who had an episode of posteromedial painful popping we...
متن کاملEffect of Posterior Horn Medial Meniscus Root Tear on In Vivo Knee Kinematics
BACKGROUND Medial meniscus root tear (MMRT) is a recently recognized yet frequently missed meniscal tear pattern that biomechanically creates an environment approaching meniscal deficiency. HYPOTHESIS/PURPOSE The purpose of this study was to assess the effect of MMRT on tibiofemoral kinematics and arthrokinematics during daily activities by comparing the injured knees of subjects with isolate...
متن کاملBiomechanical consequences of a tear of the posterior root of the medial meniscus. Surgical technique.
BACKGROUND Tears of the posterior root of the medial meniscus are becoming increasingly recognized. They can cause rapidly progressive arthritis, yet their biomechanical effects are not understood. The goal of this study was to determine the effects of posterior root tears of the medial meniscus and their repairs on tibiofemoral joint contact pressure and kinematics. METHODS Nine fresh-frozen...
متن کاملArthroscopic Direct Repair for a Complete Radial Tear of the Posterior Root of the Medial Meniscus
We report here on a new arthroscopic direct repair technique for a radial tear of the posterior root of the medial meniscus (PRMM) using a posterior trans-septal portal. Radial tears of the PRMM are commonly observed in the elderly population of Korea and Japan, and the life style of these people requires squatting and kneeling down in daily life. A radial tear of the PRMM results in the loss o...
