If Your Knee Hurts and the MRI Was Normal

Knee pain frustrates patients and clinicians equally because the knee is the middle joint between the hip and the ankle — and it ends up doing the work neither of those joints is doing properly. You can have a perfectly healthy knee that hurts terribly because the hip above it isn’t moving right, or the ankle below it has lost mobility, or the lumbar spine is creating a leg-length asymmetry.

That’s why so many patients with chronic knee pain go through cortisone, physical therapy, and even arthroscopic surgery without lasting resolution. The knee is the symptom. The cause is somewhere else.

Our Meridian clinic’s approach to knee pain starts with finding where the actual dysfunction is happening. Sometimes that’s the knee itself. More often, it isn’t.

What to Do Right Now

• Ice for 15-20 minutes if the pain is acute or there’s swelling. Heat for chronic stiffness without swelling.
• Avoid deep squats and stairs as much as possible until evaluated.
• Skip the knee brace unless prescribed. Long-term bracing weakens the supporting muscles.
• If you can’t bear weight, the knee is visibly swollen, locked, or you heard a pop with the injury — get it imaged at urgent care.
• Don’t push through sharp pain. Working out around acute knee pain is how minor problems become surgical ones.

Common Causes of Knee Pain

Patellofemoral Pain Syndrome (Runner's Knee)

Pain around or behind the kneecap, worse with stairs, squats, and prolonged sitting. The kneecap isn’t tracking properly in its groove, often because of weak hip stabilizers or tight quadriceps. Common in runners, cyclists, and women due to hip biomechanics. Highly treatable with targeted strengthening and addressing the upstream causes.

IT Band Syndrome

Sharp pain on the outer side of the knee, especially during running or downhill walking. The IT band — the thick band of tissue running down the outside of your thigh — gets tight and irritates where it crosses the knee. Common in runners. Treatment requires addressing the hip muscle imbalance that caused the IT band tightness in the first place — stretching and rolling the IT band itself rarely fixes the underlying issue.

Patellar Tendonitis (Jumper's Knee)

Pain just below the kneecap, particularly with jumping, squatting, or going down stairs. The patellar tendon is chronically inflamed. Common in basketball, volleyball, and running. Responds well to shockwave therapy combined with proper loading exercises.

Meniscus Injuries

Sharp pain often with a specific twisting injury, sometimes with locking or catching. The meniscus is the cartilage cushion in the knee. Small tears often heal with conservative care. Larger tears, displaced flaps, or tears in older patients with arthritis sometimes need surgery — but research increasingly shows that arthroscopic meniscus surgery for degenerative tears doesn’t produce better outcomes than conservative care for most patients.

Knee Osteoarthritis

Chronic, dull pain with stiffness, especially in the morning or after sitting. Worse with weight-bearing activity. X-rays show joint space narrowing and bone spurs. Real arthritis, but most arthritis pain has a significant component of biomechanical dysfunction layered on top — and addressing that biomechanical component often produces dramatic symptom improvement even though the arthritis itself doesn’t change.

Referred Pain From the Hip or Lumbar Spine

Sometimes the knee hurts because the hip or lower back is creating compensatory loading patterns that overload the knee. Treating the knee directly produces little change. Treating the actual driver — usually upstream — resolves the knee symptoms within a few visits. We see this pattern frequently.

Why Hip and Ankle Function Matter for Knee Pain

The knee is a hinge joint with very limited range of motion compared to the hip and ankle. When the hip doesn’t rotate properly or the ankle doesn’t dorsiflex enough, the knee compensates by twisting or shifting in ways it isn’t designed to. Over time this produces real damage to the knee — irritated tendons, displaced kneecap tracking, accelerated cartilage wear.

This is why a patient can have a perfectly intact knee on MRI and still have severe knee pain. The knee structure is fine. The way it’s being loaded by adjacent joints is destroying it.

Our exam looks at hip rotation, ankle dorsiflexion, foot mechanics, and lumbar function on every knee patient. Often the knee is the symptom of dysfunction one or two joints away.

How We Diagnose Knee Pain

• Knee-specific orthopedic tests — McMurray’s, Apley’s, Lachman’s, valgus/varus stress tests, patellar grind
• Hip and ankle assessment — range of motion, strength, mechanics
• Lumbar spine evaluation — Gonstead motion palpation, neurological screening
• Functional movement assessment — squat, single-leg stance, gait analysis
• Imaging when warranted — standing X-rays of the knee, sometimes hip and lumbar spine
• DMX for complex cases where motion-dependent dysfunction is suspected

Treatment Plan

• Adjustments to the hip, ankle, or lumbar spine if the cause is upstream
• Soft tissue work on tight quadriceps, IT band, calves, or hamstrings
• Specific corrective exercises — typically hip strengthening for runner’s knee and IT band syndrome
• Shockwave therapy for patellar tendonitis and chronic tendon issues
• Joint mobilization for stiff knee or arthritis cases
• Activity modification during the corrective phase
• Referral for orthopedic consultation when surgical intervention is genuinely warranted

Most knee patients feel meaningful change within 4-6 visits. Full resolution typically takes 8-12 visits depending on cause and chronicity.

Frequently Asked Questions

My knee MRI showed a meniscus tear. Do I need surgery?

Often no, despite what you may have been told. Recent research has shown that arthroscopic meniscus surgery for degenerative tears (the most common kind in patients over 35) doesn’t produce better long-term outcomes than conservative care. Surgery makes sense for younger patients with traumatic tears, locking knees, or specific tear patterns that won’t heal. For most middle-aged patients with degenerative meniscus tears found on MRI, conservative care with proper biomechanical correction often resolves symptoms — and many of these tears were probably present long before the pain started anyway. Get a thorough conservative care trial before scheduling surgery.

My doctor said I have arthritis. Is there anything you can do?

Yes, and we tell patients this regularly: even with documented knee arthritis, most pain comes from the surrounding biomechanical dysfunction — not the arthritis itself. Improve hip strength, address ankle mobility, fix lumbar dysfunction, and most arthritis patients see substantial pain reduction even though their X-ray doesn’t change. Severe end-stage arthritis with bone-on-bone contact eventually does need replacement, but most patients diagnosed with knee arthritis can extend years of comfortable function with proper conservative care. Don’t accept that nothing can be done.

Why does my knee hurt when I run but feel fine the rest of the day?

Activity-specific knee pain almost always points to biomechanical dysfunction — the structure is fine, but the way you’re loading it during that activity is the problem. Common culprits: weak hip stabilizers (especially gluteus medius), poor ankle dorsiflexion, excessive pronation, IT band tightness from hip imbalance. We watch you move and identify which factor is driving your specific pattern. Once we fix the upstream issue, you can typically return to running without the knee pain returning.

My kneecap hurts. Is it the cartilage?

Possibly, but more often it’s a tracking problem rather than a structural cartilage issue. Patellofemoral pain syndrome — the most common cause of front-of-knee pain — happens when the kneecap doesn’t glide properly in its groove. The cartilage is usually fine; the alignment is off. Causes include weak hip muscles, tight quadriceps, foot mechanics, and certain postural patterns. Real cartilage damage (chondromalacia patellae) does happen but is overdiagnosed. We test specifically for both.

How fast will my knee feel better?

Most patients feel meaningful improvement within 4-6 visits. Patellofemoral pain syndrome often resolves quickly — 6-8 visits is typical. IT band syndrome similar timeline. Patellar tendonitis often takes 8-12 visits because chronic tendon tissue heals slowly. Arthritis cases improve but typically require ongoing maintenance care rather than complete resolution. We give you a realistic timeline after the exam, not a vague “could take a while.”

Is my knee pain related to my back pain?

Frequently yes. Lumbar spine dysfunction can create compensation patterns that overload one knee — leg length differences from pelvic dysfunction, altered gait from low back pain, weakness in specific muscles from nerve irritation. Patients are often surprised when their knee pain resolves after we treat their lumbar spine. We always evaluate both areas on chronic knee patients because the connection is so common.

Can I keep running while we're treating this?

Depends on the pain level and the cause. For mild-to-moderate runner’s knee or IT band syndrome, often yes — sometimes with reduced mileage or modified activity. For acute injuries, recent flare-ups, or severe pain, we recommend rest from the aggravating activity until we get on top of the inflammation. The general rule: if you can run without making it worse and the pain doesn’t last beyond the run, you can probably continue at reduced volume. If running flares it up significantly or the pain lingers, take time off. We give specific guidance based on what we find.

Will my insurance cover this?

Most major insurance plans cover chiropractic care for diagnosed knee conditions and related musculoskeletal issues. We accept Blue Cross Idaho, Regence, Pacific Source, Aetna, Cigna, United Healthcare, Medicare. Shockwave therapy specifically may be out-of-pocket as it’s still classified as elective by many insurers despite strong research support. We verify benefits before your first visit and tell you exactly what your costs will be.
