Effects of Leg Length, Sex, Laterality, and the Intermediate Femoral Cutaneous Nerve on Infrapatellar Innervation.

Background: An iatrogenic injury to the infrapatellar branch of the saphenous nerve (IPBSN) is a common precipitant of postoperative knee pain and hypoesthesia.

Purpose: To locate potential safe zones for incision by observing the patterns and pathway of the IPBSN while examining the relationship of its location to sex, laterality, and leg length.

Study Design: Descriptive laboratory study.

Spatio-temporal focal spot characterization and modeling of the NIF ARC kilojoule picosecond laser.

The advanced radiographic capability (ARC) laser system, part of the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, is a short-pulse laser capability integrated into the NIF. The ARC is designed to provide adjustable pulse lengths of ∼1-38 in four independent beamlets, each with energies up to 1 kJ (depending on pulse duration). A detailed model of the ARC lasers has been developed that predicts the time- and space-resolved focal spots on target for each shot.

Mapping the genicular arteries to provide a caution zone during knee surgery.

Introduction: Reports from the current literature show a lack of detail with depictions of the genicular arteries (GA). The intricate anatomy and infrequency of operating in the posterior knee may lead to surgeons being unfamiliar with the anatomy. The goal of this cadaveric study was to quantitatively map the arteries and create a caution zone that can be utilized when preparing and performing surgical procedures involving the knee.
