Patellofemoral Pain Syndrome (Runner’s Knee)

What is Runner’s Knee?

Patellofemoral pain syndrome (PFPS), or runner’s knee, is pain around the kneecap (patella) caused by improper tracking of the patella in its groove. It’s common in runners, cyclists, and athletes with repetitive knee loading.

Common Symptoms

• Pain around or behind the kneecap

• Pain with running, squatting, or stair use

• Grinding or popping under the kneecap

• Stiffness after sitting

Physical Therapist Diagnosis

A PT assesses patellar movement,, hip and quad strength, and movement patterns during squats and functional tasks.

Why it Happens

PFPS often results from imbalances in hip and quad strength, poor mechanics, or overtraining.

Why it Doesn’t Always Heal on Its Own

Without correcting mechanics, pain tends to recur with activity.

Ideal Physical Therapy Treatment

Treatment focuses on improving strength, alignment, and mechanics. Dry needling may reduce muscle imbalances by relaxing tight quads or hip muscles.

Key strategies include:

• Manual therapy for patellar and hip mobility

• Dry needling to address quadriceps tightness

• Strengthening of glutes, quads, and core

• Movement retraining for running, squats, and sport

• Taping or bracing as a temporary aid

Expected Outcomes

Most athletes recover within a few weeks and see significantly faster recovery time with a combination of manual therapy, movement retraining, and exercises. Addressing mechanics and movement patterns, along with proper strengthening, prevents recurrence.
