Patellofemoral Pain Syndrome
Often called “runner’s knee,” patellofemoral pain syndrome causes pain around and behind the kneecap. Learn about causes and effective treatment strategies.
What is Patellofemoral Pain Syndrome?
Patellofemoral pain syndrome (PFPS) is a broad term describing pain at the front of the knee and around the kneecap (patella). It’s one of the most common causes of knee pain, particularly in athletes, teenagers, and young adults.
The pain typically results from problems with how the kneecap moves within its groove on the thighbone (femur). When the kneecap doesn’t track properly, it can cause irritation and pain. The good news is that PFPS usually responds well to conservative treatment.
Common Causes
Overuse
Repetitive stress from running, jumping, or other activities
Muscle Imbalances
Weak quadriceps or hip muscles affecting kneecap tracking
Biomechanical Issues
Flat feet, leg alignment problems, or tight muscles
Trauma
Direct injury to the kneecap from a fall or blow
Symptoms
- Dull, aching pain in the front of the knee
- Pain worsens when climbing stairs or squatting
- Pain after sitting with bent knees for long periods
- Grinding or popping sensation in the knee
- Pain during or after exercise
- Tenderness around or behind the kneecap
“Movie Theater Sign”
A classic symptom of PFPS is pain that develops when sitting with bent knees for extended periods—like during a movie. This is sometimes called the “movie theater sign” or “theater sign.”
If you find yourself needing to straighten your legs to relieve knee pain after sitting, it may indicate PFPS.
Treatment Options
PFPS typically responds well to conservative treatment focusing on strengthening and improving biomechanics.
Rest & Activity Modification
Avoiding activities that aggravate symptoms
Physical Therapy
Strengthening and stretching exercises for proper alignment
Patellar Taping/Bracing
Supports to improve kneecap tracking
Orthotics
Shoe inserts to address foot and leg alignment issues
NSAIDs
Anti-inflammatory medications for pain relief
Focus on Strengthening
The cornerstone of PFPS treatment is a targeted exercise program. Strengthening the quadriceps (especially the inner portion), hip muscles, and core can significantly improve kneecap tracking and reduce pain.
