Knee pain.
The knee is usually the joint that complains, not the joint that is wrong. Find what the hip and ankle stopped doing, and the knee stops paying for it.
The knee is stuck in the middle of someone else's problem.
The knee is a simple hinge trapped between two joints that rotate. The hip above it and the ankle below it are built to turn; the knee is not. When the hip loses rotation or the ankle loses the ability to bend forward over the foot, that motion does not disappear — it gets taken up by the knee, which is poorly designed to absorb it. Repeat that for a few thousand steps a day and something in the knee starts to complain.
That is why so much knee pain arrives without an injury. There was no moment. There was a gradual accumulation of the knee doing a job it was never meant to do, until a tendon, the cartilage under the kneecap, or the joint lining reached its limit.
The common presentations we see are patellofemoral pain around and under the kneecap, patellar and quadriceps tendinopathy at the front, iliotibial band irritation on the outside, pes anserine irritation on the inner shin, and degenerative change in the joint itself. They feel different, they respond to different work, and telling them apart is what the examination is for.
At our Jacksonville and Orange Park offices we assess the knee as part of a chain — hip rotation, glute strength, ankle mobility, and how you actually load the leg when you squat, step, and walk. Treating the sore spot without changing what is overloading it is why knee pain so often comes back.
Does this sound familiar?
Treat the driver, not just the sore spot.
Why the hip and ankle decide what your knee feels
Watch someone with knee pain do a single-leg squat and the story usually tells itself. The knee drifts inward toward the midline while the pelvis drops on the opposite side. That is not a knee fault — it is the hip failing to control rotation, and the knee is simply where the resulting stress lands.
The same applies below. If the ankle cannot bend forward far enough — a common consequence of old sprains that were never properly rehabilitated — the body finds that range elsewhere. Often that means the knee travels in ways it should not, or the foot rolls in to buy the motion, which rotates the shin and torques the knee from below.
This is why isolated knee treatment so often disappoints. You can settle the irritated tissue down, but if the mechanics that overloaded it are unchanged, the clock simply restarts.
Telling the common knee problems apart
Pain around and behind the kneecap that worsens with stairs, squatting, and prolonged sitting points toward patellofemoral pain — a load-distribution problem at the kneecap rather than damage to it.
Pain in a specific spot just below the kneecap, worse with jumping and decelerating, points toward patellar tendinopathy. This one responds to shockwave and heavy slow loading, and it responds poorly to rest alone.
Pain on the outside of the knee that appears at a predictable distance into a run or walk suggests iliotibial band irritation, usually driven by hip control. Pain on the inner shin a few centimetres below the joint line suggests pes anserine irritation.
Deep, diffuse ache with morning stiffness that eases within half an hour, in an older knee with a history of hard use, points toward degenerative change. That does not mean nothing can be done — function and pain often improve substantially even when the joint surface does not.
What arthritis in the knee does and does not mean
An X-ray showing joint space narrowing is extremely common past middle age, and the degree of change on film corresponds poorly with how much pain someone has. Plenty of people have significant radiographic change and very little pain; plenty of others have modest change and considerable pain.
What that means practically is that a report is not a prognosis. Strength, load tolerance, and how well the surrounding joints share the work all influence how an arthritic knee feels and functions, and all three can be changed.
Where a joint is genuinely worn to the point that function is severely limited despite good conservative care, joint replacement is a legitimate and effective operation, and we will say so rather than keep you in treatment that is not moving the needle.
How we assess it
The evaluation looks at the knee and then deliberately looks away from it. We assess hip rotation and extension, glute strength and control, ankle dorsiflexion, and how the leg behaves under single-leg load. We palpate the specific structures to localise which tissue is actually irritated.
Imaging is ordered when the findings call for it — a locking or giving-way knee, a significant traumatic mechanism, or a case not responding as expected. It is not the default first step, because a degenerative finding on a scan will not tell us why this knee started hurting this year.
