Background: Posterior medial meniscus root (PMMR) tears have a serious effect on knee joint biomechanics. Currently used techniques for refixation of the PMMR include the transtibial pull-out repair (TP) and suture anchor repair (SA). These techniques have not been compared biomechanically.
View Article and Find Full Text PDFBackground: A tear of the posterior medial meniscus root (PMMR) is increasingly recognized as a serious knee joint injury. Several suture techniques for arthroscopic transtibial pull-out repair have been described; however, only limited data about the biomechanical properties of these techniques are currently available.
Hypothesis: There are significant differences between the tested suture techniques, with more complex suture configurations providing superior biomechanical properties.
Purpose: To evaluate the biomechanical properties of four different suture materials for arthroscopic transtibial pull-out repair of posterior meniscus root tears, with special focus on the meniscus-suture interface.
Methods: Forty fresh-frozen lateral porcine menisci were used. The posterior meniscus root was sutured in a standardized fashion with a simple stitch using four different suture materials: group A, No.
