Comparison of the clinical outcomes of transtibial pull-out repair for medial meniscus posterior root tear: Two simple stitches versus modified Mason-Allen suture

Abstract

using the FasT-Fix all-inside suture device combined with Ultrabraid for stronger repair (FasT-Fix 36 modified Mason-Allen technique, F-MMA) [4]. Furumatsu et al. reported that F-MMA suture 37 configuration obtained better meniscal healing and superior clinical outcomes than single FasT-Fix 38 repairs in patients with MMPRTs [5].Recently, a new simple fixation technique using two simple stitches (TSS) under an expected initial tension was reported [6]. Other studies on transtibial pullout repair using TSS report that it is one of the major repair techniques of MMPRT treatment [7,8]. The biomechanical study revealed the superiority of F-MMA in the ultimate failure load compared to TSS suture configuration using porcine 43 models [4,9]. On the other hand, favourable clinical outcomes and high clinical survival rate were 44 reported using TSS technique [8, 10]． 45In the past, there have been no studies to compare the clinical efficacy between F-MMA and TSS 46 technique in the pullout repair of MMPRT. It was hypothesized that the clinical outcomes of TSS were comparable to those of the F-MMA suture configuration. This study aimed to compare the clinical

The efficacy of meniscus posterior root tears repair: A systematic review and meta-analysis

“…Functional improvement with repair was significantly greater in the most studies comparing it with other treatment of MMPRTs, but there were differences between the different repair techniques. 10,22,29 Moreover, changes in meniscus extrusion affect the clinic outcomes after MMPRTs repair, three studies reported their findings 12,17,19 and the results were similar. Chung et al 12 reported that patients with decreased meniscus extrusion had better surgical outcomes in terms of clinical scores and radiographic findings, indicating the importance of reducing meniscus extrusion.…”

“…A flow chart regarding the screening of the articles is shown in Figure 1; 22 studies were selected for fulltext review, all of which satisfied our inclusion and exclusion criteria; 4 studies included partial meniscectomy groups, 2 studies included conservative groups, all studies included repair groups. In the 22 studies, 14 were Level III evidence, 5,[9][10][11][12][13][17][18][19][20]22,[27][28][29] 8 were Level IV evidence. [6][7][8]21,24,[30][31][32] Among the Level III evidence comparative studies, three compared partial meniscectomy with pull-out suture repair 9,13,27 and one compared conservative treatment with pull-out suture repair, 28 one compared meniscectomy, repair and conservative treatment.…”

“…Of these, 786 patients (793 cases) undergone MMPRTs repair surgery in all of the studies. 5 –13,17 –22,24,27 –32 The remaining 133 patients (133 cases) were treated with non-operative methods 11,28 or partial meniscectomy. 5,11,13,27…”

“…IKDC scores. A total of 13 studies or subgroups 5,9,10,12,13,[19][20][21][22]24,27,29,30 including 541 patients were used to evaluate the IKDC improvement. The pooled improvement in IKDC scores was 31.73 with [29.79, 33.66] as the 95% confidence interval (CI), measured in SD units of the difference scores (P < 0.001).…”
