All credit to Flapjack. If you are on MW too, thank you.
Fixed it and ended up nicking myself in the process. Lol! The front panel is glued which I had to force it off. The housing of the thigh is secured by 2 screws. Open that up, rotated the leg and placed everything back together again.
Edit: Just to add. The thigh pieces are held together by yellow rectangular piece at the top. So 4 pieces in total including the front panel. You can carefully slide down the inner thigh piece so you don't have to pry the yellow rectangular piece off when dissasembling it.
