There is a certain technique of foot strike that runners use for distance running, and that's known as midfoot striking.
Your issue, commonly known as runner's knee, seems to be likely from the biomechanical issue discussed in this article. In essence, if your footfalls are striking hard on the heel, then the entire shock of the impact is traveling directly up your shin to the first flexible part that can dissipate that energy: your knee.
This video explains the difference between three running styles. Beginners tend to gravitate toward heel-striking, because that's what we're used to, from the time we're children.
By striking at the midfoot instead, the shock is distributed more evenly and dissipated before it gets to your knee. But posture alone won't always be the solution. Sometimes, we do have to rely on proper equipment, and that means the right shoes for the job.
Some advocate barefoot or minimal-shoe running because it more closely mimics our ancestral method of running. I am personally not a barefoot/minimal runner for various reasons, so I wear a particular style of shoe that fits my running style. This is just an illustration that running shoes and styles are individualized preferences, but that finding the right shoes for your style can make a world of difference.
When I was running with the wrong shoes, I could barely get a mile and a half before one of my knees would start throbbing in excruciating pain. I felt disheartened because I was training for my first half-marathon. I visited a running store and got fitted for the proper shoes and miraculously, I was better. My knees didn't hurt, and while I had to skip that half-marathon, I did manage to complete one that followed later in the year.
The problem was that I was wearing shoes that were too lightweight and also fitted exactly to my regular size, rather than a size and a half larger to allow for room for the toes to move.
I would not recommend running on your toes, but for indoor sports that require a lot of twists, turns, starts, and stops, making the primary point of impact the ball of your foot may provide more performance gains. There will be more flexibility and quickness, less energy wasted in starting and stopping as with heel-strike styles, less wear and tear on your joints by allowing your feet to absorb the impact rather than your knees, and most definitely quieter!
While the form recommendations in the links I provided focus more on distance running, the mechanics and theories can be translated fairly easily to your situation.
