Bridge-Enhanced Anterior Cruciate Ligament Repair Using Adjustable-Loop Cortical Suspensory Femoral Fixation.

Presented here is a modified technique for bridge-enhanced anterior cruciate ligament repair using adjustable-loop cortical suspensory femoral fixation. Advantages include the elimination of the need for a larger femoral-side incision and elimination of the risk of knot slippage while securing fixation of the anterior cruciate ligament repair suture.

Uncertainty Estimation for the Brillouin Frequency Shift Measurement Using a Scanning Tandem Fabry-Pérot Interferometer.

The expanded uncertainty of the measured Brillouin scattering shift frequencies is essential in assessing the measurements of parameters of various materials. We describe the general operation principles of a Brillouin light scattering (BLS) spectrometer with a high-power laser and a scanning tandem Fabry-Pérot interferometer (TFPI) for material characterization. Various uncertainty components have been analyzed for the BLS spectrometer following the Guide to the Expression of Uncertainty in Measurement (GUM).

Arthroscopic Medial Meniscus Posterior Root Repair with Centralization Using Knotless Suture Anchors.

Medial meniscus posterior root tears can lead to rapid progression of knee arthritis because of loss of the stress distribution function of the meniscus. Medial meniscus root repair can restore stress distribution and improve clinical outcome. In cases of medial meniscus root tears with meniscal extrusion, centralization may help reduce extrusion and protect the root repair.
