During my 20s and 30s, when I had problems with the outer knee, usually situated at the lateral part of the knee, I find this asana beneficial.
One such asana that is good for the ITB band is the asana shown in the two pictures. Both are known as Trinkoasna (Triangle Pose). It will be a good idea to stretch like this for 20sec on each side, left and right hand side of the body.
Knees are to be straight. Where we are bending, the opposite side of the body is benefiting from the stretch. A guide can correct for good posture. One should stand laterally and not moving the body to the front or back.
Usually, we do many of the asanas and forget to do this asana., This is one asana which will be good for the lateral part of the knee.
Try it! Especially before and after the runs.
