Results of Meniscus Allograft Transplantation Using Bone Fixation

Abstract

Meniscus allograft transplantation using bone fixation resulted in significant symptomatic and functional improvements. Magnetic resonance imaging or second-look arthroscopy was necessary to assess allograft status even after favorable clinical outcome. Meniscus allograft transplantation with bone fixation is considered effective for symptomatic, totally meniscectomized knees.

Current status of second-look arthroscopy after meniscal allograft transplantation: review of the literature

“…For this review, 15 studies [4,6,[9][10][11][12][13][14][15][16][17][18][19][20][21] reported their observations from second-look arthroscopies (Tables 1, 2). However, there was no mention of clear recommendations regarding ''when second-look arthroscopy should be performed'' and ''why second-look arthroscopy should be performed.''…”

“…In such instances, MAT is regarded as a promising approach [1,4] for the reconstruction of meniscal biomechanical properties in knees with meniscal deficits and is aided by advanced arthroscopic equipment, instruments, and techniques [25,26]. As the benefits of MAT, including pain relief and functional improvement, have been demonstrated, many methods have been performed to evaluate the clinical outcomes of MAT.…”

“…Since then, numerous reports on MAT have been published. Most of the reported results have demonstrated a significant improvement in function and pain relief after MAT [2][3][4]. However, there have been limitations in evaluating the status of MAT, such as meniscal extrusion and shrinkage.…”

“…So far, with respect to evaluation methods, in most studies, the MAT evaluation only involved clinical parameters [5,6] such as the Lysholm score, International Knee Documentation Committee score, and visual analog scale. However, few studies have used objective methods to evaluate, such as MRI or second-look arthroscopy [4,7,8].…”

Meniscus repair and regeneration: review on current methods and research potential

“…Actually, a number of orthopaedic surgeons have reported clinical and radiological mid-term results (Kim et al, 2012;Lee and Caborn, 2012). However, fixation of the allograft, whether soft-tissue or bone plug associated, remains a significant source of failure (Hommen et al, 2007).…”
