The optimal meniscal suture interval spacing for repairing longitudinal meniscal tears is poorly understood.

All lesions were repaired using two 2-0 braided sutures with the vertical mattress inside-out technique. Five suture spacings (3, 5, 7, 9, and 11 mm) with 10 samples each were tested. Each sample underwent 1000 loading cycles between 5 and 20 N (combined load) at a 75-mm\/min crosshead speed and subsequent load-to-failure testing. The tear opening gap between the 2 meniscal sutures was measured using the Digital Image Correlation system with 2 high-speed cameras after 10, 100, 500, and 1000 cycles. Gap formation, cyclic stiffness, and failure modes were measured.
