The Effects of Noninvasive Traction on SSEPs During Ankle Arthroscopy.

Background: The purpose of this study was to evaluate the effects of noninvasive ankle distraction on intraoperative somatosensory evoked potentials (SSEPs) and peripheral nerve sensibility of the foot during ankle arthroscopy.

Methods: Twenty patients undergoing ankle arthroscopy were prospectively evaluated using noninvasive ankle traction. All had preoperative clinical examination with baseline neurologic evaluation and static 2-point discrimination (2PD) test.

Allograft swelling after preparation during ACL reconstruction: do we need to upsize tunnels?

The purpose of this study was to determine whether the pull-through force of soft-tissue allografts increases over time after being hydrated with saline-soaked sponges. Eighteen aseptic soft-tissue, fresh-frozen anterior tibialis allograft specimens were thawed and sized using standard sizing guides. After sizing, initial pull-through force was measured using an Instron Model 5865 machine.
