The Part of Knee Replacement Nobody Prepares You For

Knee replacement is one of the more successful operations in modern medicine, and the numbers support that reputation.

Around 500,000 total knee replacements are performed in the United States every year, and roughly 90% of patients report reduced pain and improved quality of life afterward.

If your main problem is pain, this operation generally delivers.

But there’s a second set of numbers that almost nobody is shown before surgery, and it explains a frustration we hear regularly from people a year out.

Here it is, along with what to do about it.

Stairs, Sitting, and the Ache at the Front of Your Knee

There’s a specific knee complaint that shows up constantly, and it has a pattern so recognizable that you can often spot it from the description alone.

It hurts going down stairs more than going up.

It aches after you’ve been sitting for a while — in the car, at a desk, through a movie — and you find yourself straightening your leg out or shifting position to relieve it.

It bothers you squatting, kneeling, or getting up from a low chair.

And it’s at the front of the knee, around or underneath the kneecap, rather than off to one side.

If that’s you, you likely have what’s called patellofemoral pain — and there are two things worth knowing about it. It’s extremely common. And the most effective treatment often isn’t aimed at your knee at all.
