Changes in Magnetic Resonance Imaging Signal Intensity of Transplanted Meniscus Allografts Are Not Associated With Clinical Outcomes

Magnetic Resonance Imaging of the Postoperative Meniscus

“…However, these findings are not related to clinical outcome. 136,137 Regarding extrusion, a meniscus that extrudes early remains extruded and does not progressively worsen, whereas one that does not extrude early is unlikely to extrude within the first postoperative year. 138 Complications occur at an average rate of 21% per trial.…”

Meniscal Allograft Transplantation

“…Considering all 55 articles included in the review, none of the studies could be classified as level 1, according to the system described by Wright et al 94 Two studies could be classified as level 2 2,3 and 7 as level 3, 13,36,44,46,48,87,93 leaving 46 level 4 articles. # The Coleman methodology score 15 was also calculated for all the studies included in this review, with an average total score of 49.73 6 12.41 (range, .…”

“…The graft should be secured to the capsule through a meniscal repair technique if it is accepted that peripheral fixation is a prerequisite for healing and vascularization of the graft. Twelve 40 Lee et al 44 Lee et al 46 Kim et al 38 Lee et al 48 Lee et al 47 Kim…”

Quantitative MRI T2 Relaxation Time Evaluation of Knee Cartilage

“…Magnetic resonance imaging (MRI), as a valuable noninvasive tool, is usually applied in analyzing and evaluating meniscus and articular cartilage. 7,10,12,14,23 Recently, advanced MRI techniques (T2 relaxation time values) have shown a unique ability to quantitatively provide information regarding cartilage quality. 15,16,24,25,28 The MRI T2 relaxation time values provide a continuous variable of tissue properties, and they can not only distinguish between subjects with and without a meniscal tear but also distinguish between subjects with intrasubstance meniscal degeneration and those with a meniscal tear.…”
