Both were tested with and without an additional ST for 4 groups (n = 8 per group). Each construct underwent biomechanical testing involving 3000 loading cycles in 3 stages. After position-controlled cycles simulating full range of motion, force-controlled loading from 10 to 250 N and then from 10 to 500 N were performed before pull-to-failure testing. Elongation, stiffness, and ultimate strength were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The highest ultimate load (1505 \u00b1 87 N), a small total elongation (2.60 \u00b1 0.97 mm), and stiffness closest to the native human ligament (156.3 \u00b1 16.1 compared with 198.9 \u00b1 33.5 N\/mm; P = .192) was seen in the all-inside technique using ST. Intragroup comparison revealed that reinforcement with ST produced a smaller total elongation for the screw fixation (Screw-ALD, 6.06 \u00b1 3.60 vs Screw-ALD ST, 2.50 \u00b1 1.28 mm; P = .018) and all-inside techniques (ALD-ALD, 4.77 \u00b1 1.43 vs ALD-ALD ST, 2.60 \u00b1 0.97 mm; P = .077), albeit the latter was not significantly different. Elongation for constructs without ST increased more rapidly at higher loads compared with elongation for ST constructs. The ultimate strength was significantly increased only for constructs using the all-inside technique using ST (ALD-ALD, 1167 \u00b1 125 vs ALD-ALD ST, 1505 \u00b1 87 N; P = .010).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Adding an independent ST to PCL reconstruction led to improvement in the studied metrics by reducing the total elongation and increasing the ultimate strength, independent of the technique used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance:<\/jats:title>\n                    <jats:p>PCL reconstruction using additional ST reinforcement was biomechanically favorable in this study.
