Posterior cruciate ligament reconstruction with independent internal brace reinforcement: surgical technique and clinical outcomes with a minimum two year follow-up.

Purpose: We developed an augmentation technique for PCL reconstruction with independent internal brace reinforcement and evaluated the functional outcome after PCL reconstruction employing autologous hamstrings augmented with an internal brace system for patients with isolated or combined grade 3 posterior instability who were treated with this technique.

Methods: From January 2016 to January 2018, patients with isolated or combined grade 3 PCL tears who underwent single-bundle PCL reconstruction using autologous hamstrings augmented with independent internal braces were studied. The function of the operated knee was evaluated according to the International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner activity score.

An LC-MS/MS method for determination of novel fungicide pyraoxystrobin in rat plasma and tissues: Toxicokinetics and tissue distribution study.

A simple, specific and reproducible liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the determination of pyraoxystrobin in rat plasma and tissues. Chromatographic separation was achieved on a Zorbax Extend-C18 column (50×2.1mm I.
