Gail,
I have found good success with a 720 approach with a focus on the femoral nerve leading to saphenous n. I like to catch that distribution where it crosses the hip and throughout the quad.
For getting under the patella if you feel you need that you can certainly get in and around the fat pad. In the advanced course we show a joint space needling technique for the knee that you could probably adapt the angle to get around that area.
