I had not realised that His Holiness Pope Francis does not genuflect at the consecration and gives a simple bow of reverence to Our Lord.
At 1 hour and 46 minutes, you can see His Holiness consecrating the bread and the wine so that they become the Body and Blood of Our Lord Jesus Christ.
I can only imagine that Pope Francis has a leg or knee condition that inhibits his movement and that kneeling or genuflecting towards the Most Holy Sacrament of the Altar is a problem for him.
Above is footage of Holy Mass celebrated by Blessed Pope John Paul II in 1998.
Blessed Pope John Paul II genuflects for the consecration at 3 minutes and 35 seconds.
Below is also footage of Pope Benedict XVI celebrating Holy Mass, who genuflects for the consecration at 4 minutes and 45 seconds.
Here below is Archbishop Vincent Nichols, genuflecting at the consecration, during His Grace's celebration of Holy Mass at Westminster Cathedral at 1 hour and 4 minutes.
Pray that whatever knee problems the Holy Father is currently experiencing may be healed by the tenderness of Our Blessed Lord.
