Patellofemoral Pain

 

Patellofemoral Pain Syndrome Treatment in Princeton & Lawrenceville, NJ

Patellofemoral pain syndrome (PFPS), often called “runner’s knee,” is one of the most common causes of knee pain in active people. It typically presents as pain in the front of the knee or under the kneecap.

The pain is often worse with stairs, squatting, running, or sitting for long periods.

The good news: most cases improve with structured rehabilitation and smart load management.

At Princeton Sports and Family Medicine, P.C., we help runners, youth athletes, and active adults in Princeton, Lawrenceville, West Windsor, Plainsboro, Hopewell, Pennington, and Robbinsville address the root cause of anterior knee pain — not just the symptoms.

• Patellofemoral pain causes pain in the front of the knee.
• It is common in runners and jumping athletes.

Who This Affects + Why It Happens

Patellofemoral pain syndrome commonly affects:

• Runners
• Female athletes
• Soccer and basketball players
• Teen athletes during growth spurts
• Adults increasing activity volume

Why It Happens

The kneecap (patella) tracks within a groove at the end of the femur. When mechanics are off, the joint experiences increased stress.

Common contributors:

• Weak hip abductors
• Poor quad control
• Rapid increase in mileage
• Downhill running
• Poor landing mechanics
• Limited ankle mobility

This condition is typically an overuse problem, not a structural tear.

Risk Factors

• Female sex
• Prior knee pain
• High training load
• Muscle imbalance
• Poor footwear
• Growth-related changes in adolescents

Symptoms: What’s Normal vs. Not

Typical Symptoms

• Dull ache under or around the kneecap
• Pain with stairs (especially going down)
• Pain with squatting
• Pain after sitting with knees bent (“movie sign”)
• Mild swelling
• Crepitus (grinding sensation)

Seek Urgent Care Now If:

• Sudden major swelling
• Inability to bear weight
• True locking
• Severe instability
• Fever with joint swelling

PFPS usually does not cause dramatic swelling or instability.

Diagnosis

Diagnosis is primarily clinical.

What We Assess

• Pain location
• Squat mechanics
• Step-down control
• Hip strength
• Ankle mobility
• Running or jumping mechanics
• Training history

Imaging

Imaging is often not necessary.

X-rays may be considered if symptoms persist or if other diagnoses are suspected.

MRI is typically not required unless symptoms are atypical.

What to Expect at Your Visit

• Clear explanation of pain source
• Movement assessment
• Training load discussion
• Rehab plan focused on strength and control
• Activity modification guidance

Treatment Options

Most cases improve without surgery.

Self-Care Basics

• Reduce aggravating activities temporarily
• Avoid deep painful squats early
• Ice after activity if irritated
• Gradual return to running

Rehab / Physical Therapy Focus

• Glute strengthening
• Hip abductor strengthening
• Quad control
• Step-down training
• Single-leg stability
• Core strength
• Running form modifications when appropriate
• Load management education

Strength is more important than passive treatments.

Medications

• Short-term NSAIDs may reduce inflammation
• Acetaminophen for pain relief
• Discuss medication risks with your clinician

Taping or Bracing

Temporary taping or bracing may reduce symptoms during rehab progression.

Injections / Surgery

Rarely indicated for classic patellofemoral pain syndrome.

Return to Sport / Activity Guidance

Return is gradual and criteria-based.

Early Phase

• Reduce mileage
• Cross-train (cycling, swimming)
• Strength foundation

Mid Phase

• Gradual run progression
• Controlled plyometrics
• Single-leg loading

Late Phase

• Full running volume
• Sport-specific drills
• Cutting and agility progression

Common Mistakes to Avoid

• Increasing mileage too quickly
• Ignoring hip weakness
• Running through worsening pain
• Skipping strength work
• Changing shoes and training volume simultaneously
• Comparing recovery to others

Prevention

• Strength train 2–3 times per week
• Increase mileage gradually
• Include hip-focused exercises
• Warm up properly
• Address ankle mobility
• Avoid sudden training spikes
• Use proper footwear

FAQs

Is patellofemoral pain the same as a meniscus tear?

No. PFPS is typically an overuse condition affecting the front of the knee, not a cartilage tear inside the joint.

When can I run again?

You can usually resume running once pain is controlled and strength improves. A graded plan reduces recurrence.

Do I need imaging?

Most cases do not require imaging. Diagnosis is typically clinical.

Should I stop exercising?

No. Relative modification is usually better than complete rest.

Is this common in teen athletes in Princeton?

Yes. Growth spurts and high sports volume increase risk.

Can poor hip strength cause knee pain?

Yes. Weak hip muscles increase stress on the kneecap.

How long does recovery take?

Many cases improve within several weeks to a few months with consistent rehab.

Can this become chronic?

Yes, if strength deficits and load errors are not addressed.
