See the alternate kinesiology taping for patellar tendinitis. Both will work but it depends on your problem and anatomy as to which one will work best for you.
The idea for this taping is to provide functional support for Runner's Knee also known as Jumper's Knee or Patella Tendinitis (aka Tendonitis). You do want to pull the tape in a way that you are lifting the knee cap up slightly. A "knee sling" so to speak.
This taping requires about 75%-100% tension in the middle. With Rock Tape you can get additional tension.
You want to lay down the anchor pieces without tension. This is so the tape does not peel off.
If you are using a roll of Rock Tape, Kinesio Tape, SpiderTech tape that is not pre cut, you'll want to round the edges slightly to increase durability and prevent it from coming off at the edges.
Make sure you bend your knee up for this application. It will be sort of wrinkly and not so beautiful when you stand up and that's the way it should look and be applied.
