A Cadaveric Biomechanical Comparison of A Triple Versus Quintuple Hemi-Section Achilles Tendon Lengthening

Video Transcription

Video Summary

In this video, Shuyuan Li presents a cadaveric biomechanical comparison of triple versus quintuple hemisection Achilles tendon lengthening. The triple hemisection technique, commonly used for Achilles tendon lengthening, has limited capacity compared to the open lengthening technique. The senior author developed a quintuple hemisection technique, which demonstrated to be reliable. The study evaluated the efficacy and safety of the quintuple technique compared to the triple technique using ten matched pairs of above-knee specimens. Results showed that the quintuple technique achieved more lengthening, higher maximum dorsiflexion angle, and required less load compared to the triple technique. The quintuple technique is considered safe and advantageous over the triple technique. No ruptures were observed in the quintuple group.
