Patellofemoral pain syndrome (PFPS), commonly called runner’s knee, can frustrate active patients and challenge clinicians. The pain often appears around or behind the kneecap during running, squatting, stair climbing, jumping, or prolonged sitting.
For your clinic, PFPS presents an opportunity to deliver a more complete care plan: one that combines movement assessment, progressive rehabilitation, chiropractic care, and carefully selected high-intensity shockwave therapy.
JointWave™ should complement: not replace: exercise-based rehabilitation, load management, clinical examination, or referral when indicated. Current guidelines identify combined hip- and knee-targeted strengthening as the foundation of PFPS care. Shockwave therapy may serve as an adjunct for selected patients, particularly when symptoms persist despite appropriate conservative management.
Better Assessment. Better Loading. Better Outcomes.
Before treating anterior knee pain, confirm that PFPS represents the most likely clinical diagnosis.
PFPS commonly presents with:
- Peripatellar or retropatellar pain
- Pain during stairs, running, squatting, lunging, or jumping
- Symptoms after sitting with the knee bent
- Tenderness around the patellar margins or retinacular tissues
- Reduced tolerance for loaded knee flexion
- Contributing deficits in hip strength, lower-limb control, ankle mobility, or running mechanics
Your examination should also screen for conditions that require a different treatment strategy, including patellar tendinopathy, meniscal injury, ligament injury, osteoarthritis, bursitis, referred pain, stress fracture, or inflammatory disease.
Refer or co-manage when the patient presents with significant swelling, locking, instability, acute trauma, unexplained night pain, systemic symptoms, suspected fracture, or symptoms that do not fit a mechanical presentation.
The Mechanism: Modulate Pain. Stimulate Repair. Improve Movement.
High-intensity shockwave therapy delivers acoustic energy into targeted soft tissue. That mechanical stimulus can influence local pain sensitivity, tissue loading tolerance, and biological signaling.
Potential mechanisms include:
- ✅ Neuromodulation: Acoustic stimulation may temporarily reduce pain sensitivity and improve tolerance for movement.
- ✅ Mechanotransduction: Mechanical energy can stimulate cellular responses involved in tissue remodeling.
- ✅ Circulatory support: Shockwave therapy may promote local vascular responses and improve the tissue environment.
- ✅ Rehabilitation access: By helping selected patients tolerate exercise, treatment may create a better window for progressive strengthening.
PFPS does not always represent a discrete tissue lesion that shockwave therapy can “repair.” It often reflects a multifactorial interaction between load, strength, movement coordination, training volume, and pain sensitivity.
That distinction matters. Use JointWave to support a broader plan, not as a stand-alone solution or a promise of instant regeneration.
The PFPS-specific evidence remains limited. One small randomized trial compared exercise, shockwave therapy, and a combination of both. All groups improved, but the study did not demonstrate a clear advantage for shockwave therapy over exercise at follow-up. Therefore, the most defensible clinical position is to use JointWave as an adjunct for appropriate patients while maintaining exercise and education as the primary treatment.
The 2019 patellofemoral pain clinical practice guideline supports combined hip- and knee-targeted exercise, individualized progression, and patient education about managing patellofemoral load.
The Right Patient. The Right Time. The Right Plan.
JointWave may fit patients who meet most of the following criteria:
- ✅ Symptoms have persisted for several weeks despite reasonable self-management.
- ✅ Clinical findings remain consistent with PFPS after differential screening.
- ✅ The patient understands that exercise and load management remain essential.
- ✅ The patient can attend a short series of in-office treatments.
- ✅ The patient demonstrates a clear functional goal, such as returning to running, stairs, or recreational sport.
- ✅ The patient has no device-specific contraindication or reason for medical referral.
Avoid presenting shockwave therapy as a shortcut around rehabilitation. Instead, explain that it may help reduce symptoms and improve treatment tolerance while the patient rebuilds capacity.
Before treatment, screen according to the JointWave training materials, device instructions for use, local regulations, and your professional scope. Consider relevant factors such as bleeding risk, anticoagulant use, sensory impairment, infection, open wounds, malignancy in the treatment area, pregnancy-related precautions, skeletal maturity, and recent procedures.
The Protocol: Assess. Treat. Progress.
The following framework gives your team a practical starting point. Use your JointWave clinical training and device-specific guidance to determine applicator selection, energy, pulse count, frequency, and treatment boundaries.
1. Establish a baseline
Record:
- Numeric pain rating at rest and during a provoking task
- Patient-Specific Functional Scale or another validated functional measure
- Kujala Anterior Knee Pain Scale when appropriate
- Squat, step-down, or single-leg loading tolerance
- Running volume and aggravating activities
- Hip, knee, ankle, and foot movement findings
Choose one or two repeatable functional tests. A measurable baseline gives your patient a clearer reason to continue care and gives your team a practical way to evaluate progress.
2. Explain the treatment target
For PFPS, focus on the symptomatic peripatellar and surrounding soft tissues identified during examination. Use coupling gel and maintain controlled contact. Avoid treating directly over the patella, open growth plates, neurovascular structures, or other areas restricted by the device instructions.
Begin within the patient’s tolerance. A strong but manageable sensation may occur. Sharp, intolerable, or escalating pain signals the need to adjust the application.
3. Deliver a short treatment series
Published PFPS research has used five radial shockwave sessions separated by approximately five days. Broader musculoskeletal protocols often use three to five sessions spaced about one week apart.
For your practice, a three- to five-session trial can provide a reasonable clinical framework. Reassess symptoms, functional tolerance, and response before adding further sessions. Do not use a fixed protocol for every patient.
4. Prescribe progressive exercise
Pair JointWave with a structured program that progresses according to irritability:
- Early phase: hip-dominant strengthening, isometrics, and low-irritability knee loading
- Middle phase: progressive quadriceps and posterolateral hip strengthening
- Functional phase: step-downs, squats, lunges, running drills, and sport-specific loading
- Return phase: gradual increases in running volume, speed, hills, and training frequency
Teach relative rest rather than complete rest. Temporarily reduce painful hills, downhill running, deep squats, and sudden increases in mileage. Then rebuild exposure as symptoms and function improve.
Adjust. Stimulate. Reinforce.
Chiropractic adjustments can complement a PFPS care plan when examination identifies relevant mobility or movement restrictions.
Your assessment may include:
- Lumbopelvic control
- Hip mobility and strength
- Tibiofemoral and patellofemoral movement
- Ankle dorsiflexion
- Foot and rearfoot mechanics
- Thoracic or lumbar contributions to running and lower-extremity control
Use adjustments and manual therapy to support mobility and comfort: not to replace active rehabilitation. The guideline-supported approach places exercise at the center, with manual care serving as a targeted adjunct.
A practical workflow may look like this:
- Assess and educate: Review symptoms, load, goals, and baseline measures.
- Adjust when indicated: Address relevant joint restrictions identified during examination.
- Apply JointWave: Treat selected symptomatic soft tissues using trained, device-specific parameters.
- Load progressively: Reinforce the session with hip, quadriceps, and functional exercises.
- Track response: Monitor pain, movement quality, and activity tolerance at each visit.
Some clinicians may prefer shockwave therapy before an adjustment when guarding limits comfortable movement. Others may apply it after the adjustment to support the soft-tissue component of care. Choose the sequence based on patient response and your clinical reasoning.
The Timeline: Set Expectations. Track Progress. Adjust.
Patients may notice temporary pain modulation after an early session, but that response does not equal tissue recovery. Biological remodeling and improved load tolerance take time.
A realistic discussion may include:
- After session one: The patient may experience short-term symptom change or treatment soreness.
- By weeks two to three: Movement tolerance may begin to improve when treatment combines with consistent exercise and load management.
- By weeks four to six: Reassess running, stairs, squatting, and other functional goals.
- At six to eight weeks: Determine whether the patient demonstrates meaningful improvement in pain and function.
Do not guarantee a specific result or timeline. PFPS has multiple contributing factors, and adherence, training load, sleep, stress, biomechanics, and coexisting conditions can influence recovery.
