Eguchi et al reported a fixed loop suspensory device as having greater statistically significant strength and lower total displacement/ stretching values by comparison to an adjustable loop device. Barrow et al similarly found that the ultimate load to failure of all 3 devices tested (fixed and adjustable loops) exceeded the forces likely to be experienced in a patient's knee during the early postoperative rehabilitation period. They also reported the adjustable loop devices lengthening to a clinically significant degree when subject to cyclic loading. However, they reported this lengthening significantly reduced for one adjustable loop device when the free suture ends were tied.
