Posterior meniscal root repair: a biomechanical comparison between human and porcine menisci
2019
The aim of the present study was to compare the biomechanical characteristics of posterior meniscal root repair of porcine and human menisci. Methods. In vitro biomechanical testing was performed using 12 porcine menisci and 12 human menisci. All menisci were sectioned at the midpoint of their circumference and mounted on an electro-mechanic testing machine. The posterior root was sutured with three single stitches using a no. 2 non-absorbable suture. All specimens were subjected to cyclic axial loading followed by load-to-failure testing. Displacements were recorded at the conclusion of cycles 1, 100, 500 and 1000. Further, load-displacement curves of each specimen were recorded and analyz…
Valore del segno del doppio legamento crociato posteriore nell'imaging con RM del ginocchio
2008
Questo studio è stato condotto in maniera retrospettiva su 2436 esami di risonanza magnetica (RM) di ginocchio eseguiti nel periodo compreso tra Gennaio 2006 e Ottobre 2007. Gli esami sono stati analizzati usando come unico criterio diagnostico per la definizione del segno del doppio legamento crociato posteriore (LCP) la visualizzazione diretta di un frammento in gola intercondiloidea parallelo ed inferiore al LCP. Tale segno è stato riscontrato in 56 casi, di cui 50 successivamente sottoposti ad artroscopia che ha confermato la diagnosi in tutti i casi. Tale segno è risultato pertanto altamente sensibile e specifico nella diagnosi di rotture meniscali a manico di secchio This study was ca…
Three single loops enhance the biomechanical behavior of the transtibial pull-out technique for posterior meniscal root repair
2017
Purpose: To investigate the effect of applying an additional suture to enhance the biomechanical behavior of the suture–meniscus construct used during the transtibial pull- out repair technique. Methods: A total of 20 fresh-frozen porcine tibiae with intact medial menisci were used. In one half of all speci- mens (N = 10), two non-absorbable sutures were passed directly over the meniscal root from the tibia side of the meniscus to the femoral side (2SS). In other ten specimens, three sutures were passed over the meniscal root (3SS). All specimens were subjected to cyclic loading followed by load-to-failure testing. Displacement of the construct was recorded at 100, 500, and 1000 cycles. Fur…
