Patient Guide
Why does my knee hurt going down stairs?
Descending stairs loads the front of the knee hardest, which points toward the kneecap joint, the patellar tendon, or early arthritis.
The Short Answer
What This Pattern Usually Means
Going downstairs asks the quadriceps to control your body weight while the kneecap is pressed into the joint. Pain in that specific moment usually implicates the patellofemoral joint, the patellar tendon, or cartilage wear behind the kneecap.
Pain on the outside of the knee going downhill or downstairs, especially in runners and cyclists, is more often IT band related. Pain deep and diffuse with swelling after the fact leans toward arthritis or a meniscal problem.
Quadriceps strength is almost always part of the answer. A weak quad means the joint absorbs load the muscle should be taking, which is why strengthening changes symptoms even when the structure has not changed.

Don't Wait
When To Be Seen Sooner
- The knee locks and will not fully straighten
- Significant swelling within hours of an injury
- A sense the knee gives way under you
- Pain that has stopped you walking normally

How We'd Approach It
One Physician, One Plan
- A hands-on exam that loads each candidate structure separately
- Independent review of your existing films, not just the report
- In-room ultrasound while you move, so tissue behavior is seen live
- A diagnostic guided block when more than one structure could be responsible
- Treatment matched to the confirmed source, not a set protocol
- A written loading program so relief becomes capacity
FAQs
Questions Patients Ask
Is it arthritis if I am under fifty?
Possibly, but front-of-knee tendon and kneecap problems are far more common in that group and respond well.
Should I stop hiking?
Usually the volume and terrain get modified rather than stopped. Full rest tends to make the muscle problem worse.
