Fig. 5.

The modified Mason-Allen stitch was used for repair of the medial meniscus root tear of the right knee. (A) Two simple vertical stitches were placed 3-5 mm medial to the torn margin. (B) A horizontal loop was made by using the shuttle relay method of tying the superior ends of the vertical sutures and pulling out the inferior ends of the vertical sutures. (C) A simple vertical stitch was placed across the center of the horizontal loop, and then a cruciate-shaped stitch, so called modified Mason-Allen stitch, was made. (D) The illustration shows the ends of the strands are tied to a Henson button with adequate tension to allow physiological excursion instead of rigid fixation.
