If your knees ache on stairs, swell after a walk, or make you think twice about kneeling in the garden, you're in familiar company. Knee pain is one of the most common reasons people walk through our doors. On Episode 6 of our Pain 2 Power radio show, Dr. Dave Kashuba sat down with Dr. Richard Weiner, M.D., an orthopedic surgeon he has worked alongside since 1990, to talk about what actually helps a painful knee, and why the operating room is the last stop rather than the first.
This is the long version of that conversation, written down for anyone who has been told their knee is "getting there" and wants to know what to do in the meantime.

What's usually behind knee pain
Three culprits come up again and again. The most common is osteoarthritis, a gradual wearing of the joint that Dr. Kashuba notes he sometimes sees in patients as young as their mid-thirties, while some ninety-year-olds have none at all. The other two are ligament injuries (a ligament connects bone to bone) and tendon problems such as tendonitis (a tendon connects muscle to bone).
Which one you're dealing with changes the plan completely, which is why both doctors kept returning to the same theme: a careful evaluation comes first. As Dr. Weiner put it, "you don't treat an X-ray, you treat the patient."
Why the X-ray line matters
Plenty of people come in clutching an imaging report that sounds alarming. "Bone on bone." "Severe degenerative change." Yet you might walk the Juno Beach pier without much trouble and only feel it on the stairs at home. Someone else can have a report that sounds mild and barely get out of a car. The picture and the person don't always match, and Dr. Weiner's point was that you treat the one in front of you. That means asking what hurts, when, and what it stops you doing, then watching you move.
His test for when to get help is a good one because it has nothing to do with a pain score. You seek help, he said, "when your symptoms interfere with ADLs, which means activities of daily living." Can you carry the groceries in from the car? Get up off a low couch? Make it around the course? Those answers tell us more than a number from one to ten.
Knee arthritis treatment before surgery: the surgeon's own ladder
Dr. Weiner spent most of a radio hour on how to keep people out of his operating room. "Surgery is the last resort," Dr. Weiner said. "The first thing is conservative treatment." He described the ladder he climbs with his own patients, one rung at a time, and noted that the vast majority of the knee patients he treats never need an operation at all.
Rung one: stop aggravating it
The first step is the least glamorous. Figure out what flares the knee and do less of it, or do it differently. That might mean shorter walks on softer ground for a while, swapping deep squats in the garden for a kneeling pad and a stool, or giving the third pickleball game of the morning a rest. You keep doing the things you love, with the pressure taken off long enough for the next rung to work.
Rung two: therapy
Then therapy, and he was blunt about why it sits so high: "physical therapy is key because you need to have strong muscles to stabilize the knee to have fewer symptoms." The knee is a hinge between two long bones. When the muscles around it are weak, the joint surfaces absorb what the muscles should have. Build those muscles back and the joint has less work to do.
Rung three: medication, an injection, or a brace
Next come medication or a targeted injection, and bracing. People often ask us whether they should get a knee injection or do physical therapy, as if it were one or the other. On Dr. Weiner's ladder, therapy comes first and an injection is a tool for later, when it's needed. Between pills and an injection for a single sore joint, he leans toward the injection, on the logic that you put the oil where it squeaks rather than exposing the whole body. Whether any of that is right for you is a conversation for your physician.
Surgery only enters the picture when all of that has been tried. If you're at that point, our post on partial vs total knee replacement covers the question most people forget to ask.
What extra pounds do to a knee
Citing studies, Dr. Weiner explained that each extra pound of body weight adds roughly five pounds of stress to the knee during activities like squatting and stair climbing. So losing ten pounds can take about fifty pounds of stress off each knee.
He listed excess weight among the main risk factors for knee arthritis, alongside genetics and past injuries. You can't change your parents, and you can't un-tear the meniscus you tore playing softball in 1987. Weight is the one on that list you have a hand on.
Those are encouraging numbers. Small changes buy your knees relief, and they stack with everything else in this post. A little less load plus a little more strength is a better deal for the joint than either one alone.
Four simple exercises you can do at home
Dr. Kashuba walked listeners through a short routine that needs nothing more than a sturdy chair and a low step stool. They're the same four that open the knee section of our home exercise library. Move gently, stay within a comfortable range, and stop if anything sharpens the pain.
| Exercise | How to do it | Dose | Why it helps |
|---|---|---|---|
| Seated kick-outs | Sit at the front edge of a chair, slowly straighten one knee out in front of you, then lower it | 3 sets of 10 each side, building to 3 sets of 20 | Strengthens the quadriceps, including the muscle on the inside of the knee that tracks the kneecap |
| Standing knee curls | Hold the back of the chair, stand tall, bring one heel toward your seat as far as comfortable | 3 sets of 10, building to 20 | Works the hamstring through its range |
| Sit-to-stands with a pillow | Hold a light pillow out in front as you stand, and keep it reached forward as you sit back down | 3 sets of 10 | Makes you hinge at the hip, so the hip takes the load instead of the knee |
| Step-stool lean-ins | Hand on the chair, one foot on a low stool, rock your weight forward over that foot and back. No stepping up | Slow and controlled | Loads the knee through a small, safe range without impact |
A few notes from Dave that don't fit in a table. On the knee curls, do one leg at a time. His line on the show was that doing both at once is how you end up on the floor. On the sit-to-stands, the pillow is there for a reason. The joint that starts a movement takes the brunt of the load, and reaching forward makes the hips start it, which they handle far better than your knees do. On the lean-ins, resist the urge to turn it into a step-up. The point is a slow, controlled lean, repeated.
Round the routine out with regular walking, which both doctors recommended. And thinking has moved past strict rest: for a cranky knee, gentle movement plus elevation, ice, and light compression tends to serve you better than keeping it perfectly still.
What knee arthritis therapy looks like at our North Palm Beach clinic
A physical therapy plan for a painful knee is built around strengthening the muscles that support the joint, including the hip and ankle, which share the load, so the knee itself has less work to do. You can read the outline on our knee pain page.
The first hour
Your first visit runs about an hour, one-on-one with a therapist. We take your history, watch you walk and climb a step, and measure how far the knee bends and straightens and how strong the muscles around it are. Treatment usually starts that day, with hands-on work for joint mobility and the first pieces of a home exercise program. You leave knowing what we found and what the plan is.
Do you need a referral?
Usually not to get started. Florida's direct access law lets most people begin a physical therapy evaluation without a physician referral. Some insurance plans still want one for coverage, and Medicare needs a physician to certify your plan of care, so our front desk checks your benefits before your first visit and tells you what your plan requires. We see a lot of folks from up and down US-1, from Juno Beach to Lake Park, and there's a free lot right at the building.
From there the work progresses to strength for the quadriceps, hips and glutes, and functional practice for stairs, walking distance, and whatever you came in wanting back, whether that's eighteen holes or getting down to the grandkids' level on the floor. When you finish, the wellness gym down the hall is there if you want to keep training with people who know your history. It's a separate program that doesn't take insurance, so ask the front desk how it works.
When it's time to stop self-treating
Home exercise has limits, and knowing them protects you. Get evaluated if your knee pain isn't settling, if swelling or warmth develops, if the knee gives way or locks up, or if symptoms start interfering with your everyday activities: walking, standing, sleeping.
One situation shouldn't wait. A pop followed by sudden pain and a leg you can't stand on is a day for an orthopedic specialist or the hospital.
The pattern both doctors agreed on: the sooner a problem is looked at, the easier it usually is to address. Waiting until the knee has stopped you golfing for a season just means more ground to make back up.
If surgery does come up
Sometimes the ladder runs out. If it does, you'll be better off for having climbed it, because you walk into the operation stronger and you walk out with a head start on rehab.
Keep two things in mind before that appointment. First, a total knee isn't the only operation on the table. Dr. Weiner made a strong case on air that many people who get a total could have had a partial, and the post on partial vs total knee replacement lays out his reasoning. Second, if your problem turns out to be a small, contained area of damaged cartilage rather than a worn-out joint, there's a different path again, covered in our post on cartilage transplant knee recovery.
Either way, the quadriceps you build now are the quadriceps you'll have after the operation. Nothing you do on this page is wasted if surgery does come.
Start with an evaluation, not an operation
Most knee pain responds to conservative care, and finding out where you stand costs you a phone call. Our therapists evaluate your knee, tell you honestly whether therapy is likely to help, and coordinate with your physician or an orthopedic specialist when you need one. Call us at 561-624-4263, request an evaluation online, browse the physical therapy questions in our FAQ, or hear the full conversation on the Pain 2 Power podcast.
