The Short Answer
Pain specifically when going down stairs is the hallmark sign of Patellar Tracking Disorder caused by tight quadriceps. When your quad muscles are glued down with adhesions, they cannot lengthen properly to lower your leg. Instead, they pull your kneecap (patella) aggressively into the groove of your thigh bone, grinding the cartilage. Releasing the quad adhesions stops the grinding instantly.
You can walk on flat ground just fine. You can even walk up stairs without much trouble.
But the moment you have to walk down a flight of stairs, or hike down a hill, your knees scream.
Many patients are told by their doctors, "Well, you're getting older, it's probably just arthritis. Try to avoid stairs."
This is terrible advice. While arthritis exists, pain that is specific to descending is almost always a soft tissue problem, not a bone problem. And soft tissue problems can be fixed.
The Mechanics of "Down"
Why is going down harder than going up?
When you walk down stairs, your quadriceps muscles (the big muscles on the front of your thigh) have to perform an eccentric contraction. This means they have to lengthen while under load to lower your body weight gently to the next step.
Think of your quads like a brake cable. To lower a car down a hill, you need to let the cable out smoothly.
But if your quads are full of adhesions (scar tissue), they can't lengthen smoothly. They are stuck.
The Grinding Kneecap
Your kneecap (patella) floats inside the tendon of your quadriceps muscle. It acts like a pulley.
When your quads are healthy and flexible, the kneecap glides smoothly in its groove.
When your quads are tight and adhered, they pull the kneecap backward, jamming it into the thigh bone (femur).
Now, add the pressure of going down stairs. You are putting 3-4 times your body weight on that leg, while simultaneously jamming the kneecap into the bone.
Grind. Grind. Grind.
That sharp pain isn't your bones falling apart; it's your kneecap being strangled by your own muscles.
Save Your Cartilage
If you ignore this, that grinding will eventually wear away the cartilage on the back of your kneecap. That is arthritis (Chondromalacia Patella). Once the cartilage is gone, it's gone.
But right now? If it's just pain, you likely still have cartilage left. You just need to stop the grinding.

The Fix: Lengthen the Quads
Foam rolling helps a little, but it can't break deep scar tissue.
At Snake River Acupuncture, we use the Adhesion Release Method (ARM) to target the four muscles of the quadriceps.
We find the specific fibers that are glued together and physically separate them. This restores the "brake cable's" ability to lengthen.
Once the quads can lengthen properly:
- The pressure on the kneecap releases.
- The tracking improves (it stops grinding).
- You can walk down stairs without a second thought.
