Knee Pain Physical Therapy in Louisville, KY
Clinical Approach Designed by Dr. Brandon Evans, PT, DPT | Kentucky Is a Direct-Access State | No Physician Referral Required
Get to the Real Cause of Your Knee Pain
Knee pain is one of the most common reasons adults over 45 come to see us, and it is also one of the most misunderstood. Osteoarthritis, a meniscus tear, patellofemoral pain, IT band syndrome, and bursitis can all cause pain in roughly the same location, but they respond to very different treatment approaches.
At ProActive Physical Therapy and Wellness, we start with a thorough evaluation to identify what is actually driving your knee pain, then build a plan around that specific cause, designed by Dr. Brandon Evans, PT, DPT. Most knee pain does not require injections or surgery to resolve, and getting a clear answer early is what keeps minor issues from becoming bigger ones.

What Causes Knee Pain?
The knee is a hinge joint that depends heavily on the muscles above and below it, at the hip and the foot and ankle, for stability and shock absorption. Because of that, knee pain often has a cause that is not actually located at the knee.
The most common direct causes are osteoarthritis, or wear and thinning of the joint cartilage, along with meniscus tears, ligament injuries such as an ACL or MCL sprain, patellofemoral pain from irritation under or around the kneecap, IT band syndrome, patellar tendinopathy, and bursitis. Because the treatment approach differs depending on which of these is actually happening, identifying the true source matters more than just knowing that your knee hurts.
How Your Hips Affect Your Knees
Weakness or poor control at the hip is one of the most consistently documented contributors to knee pain. When the hip abductor and external rotator muscles are weak, the thigh tends to drift inward during walking, stair climbing, and single-leg activities, increasing stress on the front and outer knee and altering load through the joint. This pattern has been linked to patellofemoral pain, IT band syndrome, and increased loading on the ACL during landing and pivoting movements. A 2009 systematic review found that individuals with patellofemoral pain consistently show measurable hip muscle weakness compared with pain-free individuals, and hip strengthening is now a standard, evidence-backed part of treating knee pain rather than an afterthought.
This is why a knee evaluation at ProActive always includes an assessment of hip strength and control, not just the knee itself. If hip pain or weakness is a distinct problem in its own right, our Hip Pain Physical Therapy page covers evaluation and treatment for that specifically. Foot and ankle mechanics matter too: flat feet, overarched feet, or worn and unsupportive footwear can change how load travels up through the leg into the knee. If that is part of your picture, our Foot Pain Physical Therapy page covers that connection in more depth.
When You Should See a Doctor Before Starting Physical Therapy
Most knee pain is safe to evaluate with physical therapy first. But a small number of cases need urgent medical attention. Seek immediate care if you cannot bear any weight on the leg after an injury, if the knee looks visibly deformed or is locked in one position after trauma, or if you have signs of a joint infection, such as fever, redness, warmth, and significant swelling in the joint. Sudden calf swelling, redness, or warmth, especially after a period of immobility or recent surgery, can be a sign of a blood clot and also needs prompt medical evaluation. If any of that applies to you, please go to an emergency room or see your physician first, then come talk to us.
Is It Actually Osteoarthritis, or Something Else?
"Arthritis" gets applied to almost any knee pain in adults over 45, and it also gets over-applied as a catch-all label when the true cause has not been pinned down. Two conditions in particular get confused with osteoarthritis: patellofemoral pain syndrome, where pain sits at the front of the knee around the kneecap and is usually a mechanical tracking or loading issue rather than joint wear, and a meniscus tear, which can cause deeper joint-line pain along with catching, locking, or a sense of the knee giving way. All three can coexist, particularly as the knee ages. A hands-on evaluation, including how your symptoms respond to specific movements and positions, is what actually distinguishes between them, not an X-ray alone or a generic stretching routine pulled from a video.
Does "Bone-on-Bone" Arthritis Actually Cause Knee Pain?
Many people with knee pain are told their X-rays show bone-on-bone arthritis. That description can sound alarming, and it can create the impression that two exposed bones are painfully grinding against each other every time the knee moves. Knee pain is more complex than what shows up on an X-ray.
The Awake Knee Study
A well-known 1998 study by orthopedic surgeon Dr. Scott Dye examined which structures inside the knee are actually capable of producing pain. Dr. Dye underwent arthroscopy on both of his own knees while awake, using local anesthetic only around the small skin incisions and none inside the joint itself. This allowed different internal knee structures to be touched individually with an arthroscopic probe while he described what he felt.
The articular cartilage covering the back of the kneecap produced essentially no sensation when touched. Structures such as the infrapatellar fat pad, also known as Hoffa's fat pad, along with the anterior synovium and the joint capsule, produced intense, clearly localized pain.
What This Means for Someone With Arthritis
This does not mean osteoarthritis cannot cause knee pain, and it does not mean every painful arthritic knee is actually a fat-pad problem. It was an experimental pain-mapping study involving one individual and two healthy, uninjured knees, not a clinical trial involving people with severe knee osteoarthritis, so the findings should not be used to claim that osteoarthritis is painless or that the fat pad is always the source of pain.
What it does demonstrate is that the amount of cartilage loss visible on an X-ray does not identify the exact tissue producing a person's pain. Articular cartilage has very little sensory innervation. Pain associated with knee osteoarthritis is more likely to come from other pain-sensitive tissues in and around the joint, including:
- The infrapatellar fat pad
- The synovial lining
- The joint capsule
- The ligaments and tendons
- The muscles surrounding the knee
- The subchondral bone beneath the cartilage
The infrapatellar fat pad is now understood to be more than a passive cushion. Research indicates it interacts closely with the synovial lining and may contribute to inflammation and pain in some people with knee osteoarthritis.
An X-Ray Is Only Part of the Picture
Two people can have very similar knee X-rays and experience dramatically different symptoms. One may have advanced joint-space narrowing with relatively little discomfort, while another has significant pain despite milder imaging findings. This is why treatment decisions should not be based on terms like bone-on-bone, wear and tear, or degeneration alone. A thorough evaluation also considers where the pain is located, which movements aggravate it, knee strength and mobility, hip and ankle function, swelling and joint sensitivity, walking, stair, and squat mechanics, and your activity level, goals, and overall health.
What This Means for Treatment
An arthritic finding on an X-ray does not automatically mean the knee is damaged beyond help or that surgery is the only option. Because pain can be influenced by several sensitive structures, not simply cartilage loss, many people improve through an individualized program that addresses strength, mobility, load tolerance, movement mechanics, and confidence using the knee. The goal is not to pretend arthritis is absent. It is to determine how much of your pain and functional limitation can be improved, rather than assuming the X-ray alone determines the outcome.

Physical Therapy, Cortisone Injections, and Knee Replacement Surgery: What Is the Difference?
All three have a role depending on what is actually driving your knee pain. A cortisone injection can temporarily reduce inflammation and pain in the joint, which is sometimes useful, but it does not correct the underlying mechanical cause and its relief is often temporary. Knee replacement surgery has its place for advanced, severe osteoarthritis, but it is a major procedure that is not the right first step for most people with knee pain. Physical therapy identifies the specific source of your pain and builds a structured plan, manual therapy to improve joint mobility, paired with an individualized strengthening program for the hip, knee, and foot that addresses the mechanical issues actually keeping the joint irritated, so relief is more likely to hold and progression to more invasive treatment is less likely to be needed.
Physical therapy at ProActive includes:
- A hands-on evaluation to identify the actual source of your knee pain
- Manual therapy to improve joint mobility and reduce irritation
- A personalized strengthening plan for the hip, knee, and foot that corrects the underlying mechanical cause
- Guidance on footwear, activity modification, and daily habits that aggravate or relieve your symptoms
- Adjunct treatments such as shockwave therapy or dry needling for stubborn tendon or muscle-related pain, when appropriate
- Coordination with your physician when imaging or a specialist referral is genuinely needed
This is not:
- A generic exercise sheet unrelated to your specific cause
- A quick fix with no plan for what happens after
- A guarantee that surgery or injections will never be needed
- A substitute for emergency or physician care when red flags are present
Built on Evidence-Based Care, Not Guesswork
Our approach to knee pain follows the clinical practice guidelines published by the Academy of Orthopaedic Physical Therapy of the American Physical Therapy Association, which classify knee pain into distinct diagnostic categories, including patellofemoral pain and meniscal or articular cartilage lesions, and recommend structured exercise and manual therapy programs specific to each. Across knee conditions, including osteoarthritis, targeted strengthening of the hip and knee musculature is consistently supported as a first-line, conservative treatment, and a biomechanical review of the research confirms that abnormal hip mechanics are a documented contributor to patellofemoral pain, IT band syndrome, and ACL loading. We start with a thorough one-on-one evaluation to find your actual cause, then build a plan around it. Care is delivered by our licensed physical therapy team and progressed as your body responds, not from a generic protocol.

Common Conditions Behind Knee Pain We Treat
"Knee pain" describes the symptom. Here are the conditions most often behind it.
Knee Osteoarthritis
Symptoms: Gradual, ongoing knee stiffness and aching pain that is often worse first thing in the morning or after periods of rest, along with swelling and reduced range of motion that build over months or years.
Treatment: A progressive strengthening program for the hip and knee, manual therapy to maintain joint mobility, and activity modification guidance to reduce unnecessary strain while staying active.
Patellofemoral Pain Syndrome
Symptoms: Aching pain at the front of the knee, around or behind the kneecap, often worse with climbing stairs, squatting, or sitting for long periods with the knee bent.
Treatment: Hip and quadriceps strengthening to correct kneecap tracking, manual therapy, and gradual return to aggravating activities as mechanics improve.
Meniscus Tear
Symptoms: Pain along the inner or outer joint line, often with catching, locking, or a sense of the knee giving way, sometimes with swelling that develops over the following day.
Treatment: A structured strengthening and mobility program to reduce joint irritation and restore function, with coordination with your physician for imaging if the tear appears significant or mechanical symptoms do not improve.
ACL Tear or Sprain
Symptoms: Often a specific injury moment, sometimes with a popping sensation, followed by swelling within hours and a feeling of instability or the knee giving way, especially with pivoting or changing direction. In adults 45 and older this can also happen from a fall or an awkward twist, not just sports.
Treatment: Evaluation to determine severity and coordination with your physician for imaging when the injury looks significant. Many partial tears and some complete tears in less active individuals respond well to a structured strengthening and stability program without surgery; when surgery is appropriate, we provide both pre-surgical and post-surgical rehabilitation.
MCL Sprain
Symptoms: Pain and tenderness along the inner side of the knee, often following a direct blow to the outer knee or a twisting injury, sometimes with mild swelling and a sense of looseness when the knee is stressed sideways.
Treatment: Most MCL sprains heal well with a structured, progressive rehabilitation program addressing swelling, range of motion, and strength, without surgery. We coordinate with your physician if the sprain appears severe or is not improving as expected.
IT Band Syndrome
Symptoms: Sharp or burning pain on the outer side of the knee, typically brought on by repetitive activity like walking, cycling, or stairs, without significant swelling or locking.
Treatment: Hip strengthening to address the underlying mechanical driver, manual therapy, and activity modification while symptoms settle. Dry needling can also help release tension in tight or overactive muscles contributing to IT band irritation.
Patellar Tendinopathy
Symptoms: Pain directly at the tendon just below the kneecap, worse with jumping, squatting, or descending stairs, often with tenderness to direct pressure.
Treatment: A progressive, load-based strengthening program specific to tendon rehabilitation, paired with activity modification to allow the tendon to adapt. For tendinopathy that is slow to respond, we may also recommend shockwave therapy as an adjunct.
Bursitis
Symptoms: Localized swelling and tenderness over the front of the kneecap or the inner knee below the joint line, often related to kneeling, repetitive friction, or direct pressure.
Treatment: Activity and pressure modification, manual therapy, and a strengthening program to address any underlying mechanical contributors.

Frequently Asked Questions
What causes knee pain?
Knee pain can come from a range of causes, including osteoarthritis, a meniscus tear, patellofemoral pain, IT band syndrome, patellar tendinopathy, and bursitis. It describes a symptom, not a single diagnosis, and the right treatment depends on which of these is actually happening.
Is my knee pain arthritis or something else?
Not necessarily. Osteoarthritis is a common cause of knee pain in adults over 45, but patellofemoral pain and meniscus tears are frequently mistaken for it and require different treatment. An evaluation, not an X-ray alone, is what tells the difference.
Does a "bone-on-bone" X-ray mean I need knee replacement surgery?
Not necessarily. Cartilage itself has very little capacity to produce pain, so cartilage loss on an X-ray does not automatically explain how much pain you feel or mean surgery is your only option. A 1998 study of the knee's internal structures found that pain-sensitive tissues such as the fat pad, synovial lining, and joint capsule are much more likely sources of pain than cartilage itself. Two people can have similar X-rays and very different symptoms, which is why a thorough evaluation matters more than the X-ray label alone.
How long does knee pain take to improve?
It depends on the cause and how long symptoms have been present. Many people notice meaningful improvement within a few weeks of consistent, targeted care, though a complete plan is built around your evaluation, not a fixed timeline.
Can physical therapy help knee pain without surgery or injections?
For most cases, physical therapy is the recommended first-line, conservative treatment, before medication, injections, or surgery are considered. A structured program of manual therapy and targeted strengthening addresses the underlying mechanical cause rather than just masking the symptom.
Do I need an X-ray or MRI before starting physical therapy?
Not usually. Most knee pain can be evaluated and treated based on a hands-on clinical exam. Imaging is more useful when red flag symptoms are present or when conservative care has not helped after a reasonable trial. We will tell you directly if we think imaging is needed.
What if my knee locks, catches, or gives way?
Those are mechanical symptoms that can point toward a meniscus tear, an ACL tear, or another structural issue. They are worth a prompt evaluation, and we will coordinate with your physician for imaging if it looks warranted. See the red flag guidance above for signs that need immediate medical attention.
Can hip weakness actually cause knee pain?
Yes. Weak or poorly controlled hip muscles allow the thigh to drift inward during walking, stairs, and single-leg activity, which increases stress on the knee and is a documented contributor to patellofemoral pain, IT band syndrome, and ACL loading. That is why a knee evaluation at ProActive always includes an assessment of hip strength and control, not just the knee itself.
Do all ACL or MCL injuries need surgery?
No. Many MCL sprains and some ACL injuries, particularly in less active adults, heal well with a structured rehabilitation program and never need surgery. When surgery is the right call, we coordinate with your physician and provide both pre-surgical and post-surgical rehabilitation.
Do I need a doctor's referral to start physical therapy?
No. Kentucky is a direct-access state, which means you can start physical therapy for knee pain at ProActive Physical Therapy and Wellness without a physician's referral. Medicare and some insurance plans have their own separate requirements, so call or text us and we will walk you through what applies to your specific situation.
