Bone spurs in the knee are small, smooth growths of extra bone that form along the edges of the joint when cartilage wears down. They are not tumors, they are not cancer, and they are not something you did wrong. They are the body’s repair response to a joint that has been carrying stress for years. Most people find out they have bone spurs the same way: an X-ray taken for knee pain comes back with the word “osteophytes” on it, and suddenly a normal part of aging sounds alarming.
Here is the part that usually gets left out. The spur itself is often not what hurts. The pain almost always traces back to the osteoarthritis underneath it, or to a tendon or soft tissue that has become irritated nearby. That distinction matters, because it changes what actually helps. At Regenerative Joint Clinics in Riverdale, GA, we treat the joint, not the picture on the X-ray, and we do it without surgery.
This guide covers what bone spurs are, the seven signs patients notice most often, how we confirm them in our clinic, and which non-surgical options can settle the knee down. If you want the wider picture first, our overview of knee pain treatment options in Riverdale, GA is the place to start.
What are bone spurs in the knee?
Bone spurs, known medically as osteophytes, are bony projections that develop at the margins of a joint. In the knee they typically form where the thigh bone meets the shin bone, along the edges of the kneecap, or around the joint line you can feel on the inside of your knee.
They grow slowly. A joint that has lost cartilage becomes less stable and less evenly loaded, and bone responds to that uneven loading by laying down more bone at the rim. In a sense, bone spurs are the joint trying to spread the load over a wider surface and stabilize itself. It is a reasonable idea that the body executes imperfectly, because the extra bone can crowd the space the joint needs to move freely.
Bone spurs are extremely common with age, and plenty of people have them with no symptoms at all. Finding them on an image does not automatically mean you need a procedure. It means the joint has a history, and that history is worth understanding.
What causes bone spurs to form in the knee?
The single most common driver is osteoarthritis. As the smooth cartilage lining thins, the bones underneath take on more direct load, and new bone forms at the edges in response. This is why bone spurs and arthritis are so often found together, and why the stages of knee osteoarthritis track closely with how prominent the spurs look on an X-ray.
Other contributors we see regularly in patients across the south Atlanta area include:
- Age. Decades of load add up, and cartilage does not regenerate the way skin does.
- Old injuries. A meniscus tear, a ligament injury, or a fracture that changed how the knee tracks can accelerate wear in one compartment.
- Repetitive high-impact activity. Years of running, court sports, or heavy manual work concentrate stress through the same surfaces.
- Extra body weight. Every pound of body weight multiplies through the knee during walking and stair climbing.
- Joint alignment. Bow-legged or knock-kneed alignment loads one side of the joint harder than the other, and that side wears first.
None of those causes require surgery to address. Most of them respond to a plan that reduces load on the worn compartment and calms the inflammation that comes with it.
Do bone spurs actually cause knee pain?
Usually not directly. This is the most useful thing a patient can learn about bone spurs, so it is worth being plain about it.
Pain in an arthritic knee comes mostly from the loss of cartilage, the inflammation of the joint lining, and the irritation of soft tissues that are working harder to stabilize a joint that has become less smooth. The spur is a marker of that process rather than the source of it. Two people can have identical looking bone spurs on X-ray, and one of them can be walking three miles a day comfortably while the other cannot manage a flight of stairs.
There are exceptions. A spur positioned at the front of the knee can physically limit how far the joint straightens or bends, and one sitting near a nerve or tendon can create local irritation. But in most knees, chasing the spur is chasing the wrong target. Treating the arthritis is what changes how the knee feels.
What are the signs of bone spurs in the knee?
Patients rarely walk in saying “I think I have bone spurs.” They describe symptoms, and the imaging fills in the rest. These are the seven signs we hear most often:
- Deep, aching pain that worsens with activity. Stairs, hills, and getting out of a chair are the usual triggers.
- Morning stiffness that eases after moving. Typically fifteen to thirty minutes of stiffness, not hours.
- Grinding, clicking, or a grating sensation. Many patients describe feeling their kneecap grind. That sensation has its own name, and our guide to knee crepitus and what causes it explains when it matters and when it does not.
- Loss of full range of motion. The knee will not straighten completely or will not bend as far as the other side.
- A visible or palpable bump along the joint line. Firm, fixed, and tender when pressed.
- Swelling that comes and goes. The joint puffs up after a long day and settles overnight.
- Catching or a sense of the knee hesitating. A brief hitch during a step, distinct from the knee genuinely buckling.
If several of those sound familiar and the pain has lasted more than six weeks, it is worth having the joint imaged properly rather than guessing.
How are bone spurs in the knee diagnosed?
Bone spurs are a bone finding, so plain X-ray is the primary tool. This is where our process differs from a referral chain that sends you to three buildings before anyone explains the result.
Regenerative Joint Clinics performs digital X-ray and fluoroscopy in our Riverdale office, using the same C-arm fluoroscopy system we use to guide injections. That means the imaging that identifies your bone spurs and the imaging that guides your treatment come from the same equipment, in the same visit, read by the clinician who will build your plan.
Alongside the X-ray, our workup typically includes:
- Diagnostic musculoskeletal ultrasound. X-ray shows bone, but it does not show tendon, bursa, or joint fluid. Ultrasound fills that gap and often explains why a knee with modest bone spurs hurts more than the X-ray suggests it should.
- The WOMAC osteoarthritis index. A validated questionnaire that scores pain, stiffness, and daily function, so progress is measured against your own baseline rather than against a picture.
- A hands-on exam. Alignment, range of motion, joint line tenderness, and stability all inform which compartment is doing the suffering.
MRI is not usually needed to find bone spurs, though it becomes useful when a soft tissue injury is suspected alongside the arthritis. Our article on when a knee MRI is actually necessary covers where that line sits.
Can bone spurs be dissolved or removed without surgery?
No, and any product promising to dissolve bone spurs is not being honest with you. Bone spurs are bone. No injection, supplement, cream, or exercise removes them.
That sounds discouraging until you remember the point above: the spur is usually not the pain generator. You do not need the spur gone to feel substantially better. What you need is less load on the worn compartment, less inflammation in the joint, and better support for the structures around it. Surgical removal exists, but spurs commonly grow back, which is exactly why it sits at the end of the list rather than the beginning.
Our knee osteoarthritis program is built around that reality. Roughly 90 percent of patients in the program experience a 50 percent or greater improvement, and none of that depends on removing a single bone spur.
What non-surgical treatments help knee bone spurs and arthritis?
There is no single answer, which is why we build a Targeted Restoration Protocol for each knee rather than applying one product to everyone. The components we draw from include:
- Unloader bracing. A custom-fitted brace shifts load away from the worn compartment, which is the most direct mechanical answer to uneven wear. Our explanation of how an unloader knee brace works walks through the fitting process.
- Hyaluronic acid gel injections. FDA-approved viscosupplementation restores some of the joint’s natural lubrication and cushioning. We deliver these under fluoroscopic guidance, which matters more than usual in a joint whose anatomy has been reshaped by bone spurs. See the benefits of hyaluronic acid knee injections for what to expect.
- Corticosteroid injections. Fast, short-term relief when a knee is acutely inflamed and you need the flare settled before anything else can progress. Frequency is clinically limited, typically three to four per joint per year.
- PRP, or platelet-rich plasma. Your own concentrated platelets, used to support the joint environment when a longer-acting option is appropriate. Our comparison of cortisone versus PRP injections explains how we choose between them.
- Physical therapy by referral. Strengthening the quadriceps and hips changes how force travels through the knee. Your plan can include physical therapy, coordinated through referral, with a home program you continue between visits.
- Activity and load modification. Practical adjustments to how you climb, stand, carry, and exercise, so the joint gets a chance to calm down.
Most components of the program, including the diagnostics and the gel injections are covered by most major medical insurance plans and by Medicare. Bracing coverage depends on your plan and is confirmed before anything is ordered. PRP is the exception and is typically elective rather than covered, so we tell you that before anything is scheduled.
When should you see a knee specialist about bone spurs?
Book an evaluation if the pain has lasted more than six weeks, if stairs have become something you plan around, if the knee will not fully straighten, or if over-the-counter medication is the only thing keeping the day tolerable. Waiting rarely improves an arthritic joint, and earlier intervention gives a wider set of options.
It is also worth an appointment if you have already been told your knee is “bone on bone” and that replacement is the only path forward. That is frequently not true. Our page on non-surgical treatment for bone-on-bone knee pain covers what remains possible at that stage.
Frequently asked questions about knee bone spurs
Can bone spurs in the knee go away on their own?
No. Bone spurs are formed bone and they do not resorb or shrink on their own. Symptoms, however, can improve a great deal with treatment aimed at the underlying arthritis.
Why can I feel my knee grinding?
Grinding usually reflects roughened cartilage surfaces moving against each other, sometimes with bone spurs adding to the irregularity. Grinding without pain or swelling is common and often harmless. Grinding with pain, swelling, or catching should be evaluated.
Are bone spurs the same thing as a bone-on-bone knee?
No. “Bone on bone” describes cartilage loss severe enough that the bone surfaces contact each other. Bone spurs are extra bone at the joint edges. They frequently appear together, but they are different findings, and bone spurs can be present long before cartilage loss becomes severe.
Will I need surgery for bone spurs in my knee?
In most cases, no. Surgery is reserved for knees where a spur is mechanically blocking motion or where conservative care has genuinely been exhausted. Regenerative Joint Clinics is a non-surgical practice, and the great majority of knees we see improve without an operation.
How long does treatment take to work?
It depends on the components used. A corticosteroid injection can settle a flare within days. Hyaluronic acid and PRP work more gradually over several weeks. Bracing tends to help immediately during activity and continues to pay off as strength improves.
