Patellofemoral Syndrome (Runner's Knee)

Patellofemoral syndrome, often called runner’s knee, is a condition where the kneecap (patella) does not track properly over the femur. This misalignment causes pain in the front of the knee, especially during activities like climbing stairs, squatting, or sitting for long periods. It’s one of the most common causes of knee pain in both athletes and non-athletes, and it often develops from overuse, poor alignment, weak hip or thigh muscles, or trauma.
Diagnosis of Patellofemoral Syndrome
Diagnosis of patellofemoral syndrome usually includes:
-
Medical history review (activity level, type of sports, onset of pain).
-
Physical exam checking kneecap tracking, tenderness, and muscle imbalances.
-
Movement assessments like squatting or step-down tests to reproduce symptoms.
-
Imaging (X-ray or MRI) may be used to rule out arthritis, cartilage damage, or fractures.
Treatment for Patellofemoral Syndrome
Physical therapy is the most effective treatment for patellofemoral syndrome, focusing on realignment and strengthening. A treatment plan may include:
-
Manual therapy to improve kneecap tracking and relieve stiffness
-
Strengthening exercises for the quadriceps, hips, and glutes to support proper alignment
-
Stretching routines for tight muscles (hamstrings, IT band, and calves)
-
Taping or bracing to help guide kneecap movement during activity
-
Pain management with ice, heat, or electrical stimulation
-
Education on footwear, training modifications, and proper movement mechanics
Symptoms of Patellofeormal Syndrome
Common signs of patellofemoral syndrome include:
-
Dull, aching pain in the front of the knee (behind or around the kneecap)
-
Pain that worsens with running, squatting, climbing stairs, or prolonged sitting (“theater sign”)
-
Cracking, grinding, or popping sounds during knee movement
-
Knee stiffness after activity or rest
-
Occasional swelling or tenderness around the kneecap
Prevention of Patellofemoral Syndrome
To prevent runner’s knee or reduce recurrence:
-
Strengthen hip, glute, and quadriceps muscles regularly
-
Stretch the IT band, hamstrings, and calves to maintain flexibility
-
Use proper footwear that supports alignment
-
Avoid sudden increases in running mileage or intensity
-
Practice correct squat and lunge form during workouts
-
Address early knee pain instead of pushing through it
