Abstract:

BACKGROUND: Rectus femoris tendon is on important substitute of anterior cruciate ligament reconstruction.
OBJECTIVE: To compare the biomechanics of rectus femoris tendon and anterior cruciate ligament.
METHODS: The rectus femoris tendon and anterior cruciate ligament specimen were obtained within postmortem 9.0-10.0 hours by anatomy, and the specimens were wrapped by saline moistened paper towels immediately, then sealed and placed in a -20 ℃ refrigerator for storage. The specimens were removed from the refrigerator before experiment and each specimen was cut into two samples, 10 rectus femoris tendon specimens and 10 anterior cruciate ligament specimens in each group.
RESULTS AND CONCLUSION: The unit moludus of rectus femoris tendon was 63% of anterior cruciate ligament, the unit maximum load of rectus femoris tendon was 63% of anterior cruciate ligament. Rectus femoris tendon was suitable for anterior cruciate ligament substitute.
