“…techniques used for meniscal root repairs. 10,11,25 LaPrade et al 24 evaluated the twoesimple suture technique, modified Mason-Allen technique, and 1 and 2 doublelocking loop techniques for meniscal root repair. They found that resistance to failure for all 4 techniques was well above the threshold for the normal rehabilitation forces placed on a root repair.…”

The meniscal root attachments are critical for meniscal function by securing the menisci in place and allowing optimal shock absorption in the knee. Successful meniscal root repair has been shown to restore the knee's tibiofemoral contact pressure to the same state as an intact meniscus. Although there have been multiple different repair techniques described, there is no report in the literature regarding the use of 2 simple cinch-loop sutures for a meniscal root repair. This article presents an arthroscopic lateral meniscal root repair technique involving the use of 2 simple cinch-loop configuration sutures and tibial suture anchor fixation.

“…Regarding the suture configuration, suture techniques with a locking mechanism have better biomechanical properties than those without it. 18,19 Several suture techniques with a locking mechanism have been introduced and evaluated biomechanically. We have used the modified Mason-Allen repair for MMPRTs since 2011 because it showed good biomechanical properties for rotator cuff tears of the shoulder, which are pathologically similar to MMPRTs.…”

The repair of the meniscal root in medial meniscal posterior root tears is receiving increasing interest as more and more research highlights the positive effects of this procedure on the biomechanical restoration of the meniscus. As a testament to the findings of these studies, an international consensus statement recently acknowledged, with several supporting findings from both biomechanical and clinical studies, the effectiveness of meniscal root repairs. Various root repair techniques have been developed with the overarching goal of restoring the structure and function of the meniscus. Yet several challenges such as obtaining robust and long-term healing of degenerative tissue and minimizing meniscal extrusion remain to be overcome.

“…2 Transosseous meniscal root repair can restore the load-bearing function of the menisci 14 ; however, the strength of a medial meniscal posterior root repair is weaker than the native root attachment at the time of surgery. 11,17,24 Theoretically, repairs with better construct strength are less likely to fail. Weightbearing during postoperative rehabilitation results in compressive forces that act to extrude the meniscus and cause displacement in the repair construct.…”

Background: A 2 mm–wide ultrahigh-molecular-weight polyethylene (UHMWPE) tape improves the contact pressure at root repair sites compared with high-strength suture and provides a stronger repair construct. UHMWPE tape is commonly used in rotator cuff repair, and fixation is often achieved with knotless suture anchors. The optimal method for tape fixation for meniscal root repair has not been established. Hypothesis: The use of suture anchors for the tibial fixation of 2-mm UHMWPE tape transosseous root repairs will lead to better biomechanical performance compared with other fixation methods. Methods: The medial meniscal posterior root attachment in 25 porcine knees was divided, and a standardized transtibial root repair was performed using 2-mm UHMWPE tape. The testing was performed by cyclic loading followed by load to failure. Tibial fixation was randomized to 5 tibial fixation types: (1) cortical fixation button, (2) pound-in suture anchor with screw-down interference suture locking, (3) tap-in suture anchor with inner locking plug, (4) postscrew, and (5) postscrew and washer. Results: There was no difference in displacement during cyclic loading between tibial fixation groups except for a highly significant difference in the maximum load at failure. Repairs in both suture anchor fixation groups all failed by tape slippage at relatively low loads (median, 145 and 116 N, respectively). Repairs tied over a cortical button, postscrew, or screw and washer failed by tape breakage at loads of 431, 405, and 528 N. Conclusion: For meniscal root repairs with 2-mm UHMWPE tape, use of suture anchors offers weaker fixation compared with tying over a button or postscrew/washer. While suture anchor fixation may be adequate for nonweightbearing postoperative protocols, it may not allow for more accelerated weightbearing.
