MEDIAL PATELLA-FEMORAL LIGAMENT RECONSTRUCTION USING THE ANTERIOR HALF OF THE PERONEUS LONGUS TENDON AS A COMBINED PROCEDURE FOR RECURRENT PATELLAR INSTABILITY

Medial patella-femoral ligament reconstruction using the anterior half of the peroneus longus tendon as a combined procedure for recurrent patellar instability

Background: Medial patella-femoral ligament STATIONARY reconstruction (MPFLR) using hamstring tendon is the main procedure for recurrent patellar instability.The anterior half of the peroneus longus tendon (AHPLT) has been proven to be a useful alternate to the hamstring tendon in knee ligament reconstruction.The purpose of this study was to evalua

The correlation between serum 25-hydroxy-vitamin D levels and anti-SARS-CoV-2 S-RBD IgG and neutralizing antibody levels among cancer patients receiving COVID-19 vaccines

IntroductionDuring the coronavirus disease 2019 (COVID-19) pandemic, vitamin D has been established as an immune-modulator that reduces pro-inflammatory damage which effectively diminish the severity of COVID-19.Vitamin D also has a significant effect against influenza and dengue and increase the seroconversion following influenza vaccination.To da
