The aim of this study was to measure the immediate pull-out strengths by increasing the number of suture loops and to compare the immediate pull-out strengths of three different suturing techniques. In one group, the number of suture loops increased from 2 to 9 and the suturing technique of multiple loops through the proximal ligament stumps was used. The other group, the three different techniques were transverse, vertical, and criss-cross suture. The ultimate strength for the 2 loops was 16.62 (±6.7)N, for the 3 loops was 34.45 (±12.5)N, for the 4 loops was 54.80 (±17.7)N, for the 5 loops was 74.30 (±21.4)N, for the 6 loops was 102.49 (±13.5)N, for the 7 loops was 105.05 (±24.8)N, for the 8 loops was 129.50 (±76.1)N, for the 9 loops was 229.50 (±48.7)N. The transverse suture had a mean ultimate strength of 47.38 (±14.8)N, where-as the vertical suture failed at 76.94 (±26.4)N and the criss-cross suture at 101.82 (±25.7)N. Consequently, their strength can be improved by increasing the number of loops and we suggest that the criss-cross suture technique is reliable method for clinical use, because of high failure strength and wider apposition area of bone to ligament.
