Patellofemoral pain syndrome is pain at the front of the knee, around or behind the kneecap, where it glides in a groove on the thighbone. It usually comes from a combination of overload and how the kneecap tracks, rather than a single injury.
It is probably the most common knee complaint transcending young and old, active or sedentary. The encouraging part is that it is largely a mechanical and strength problem, which is why a well-designed rehabilitation program is so effective, and rarely requires surgery.
Symptoms
Typical complaints include:
- Aching around or behind the kneecap
- Pain with stairs, squatting, kneeling, or running
- Pain after sitting with the knee bent for a while, the 'theater sign'
- Occasional grinding or a sense of the kneecap catching
How it is diagnosed
Patellofemoral pain is largely a clinical diagnosis based on the pattern of pain and an exam of kneecap tracking, hip and thigh strength, and flexibility. Imaging is used mainly to rule out other problems when the picture is unclear or recovery stalls.
Patellofemoral pain is usually treated without surgery. Dr. Lee focuses on the root causes, the strength and timing of the hip and thigh muscles, flexibility, footwear, and training load, through a structured therapy program. Seated hip flexor raises with ankle weights are particularly helpful.
Activity modification, taping or bracing, and addressing training errors round out the plan. Avoidance of activities or exercises that require deep knee flexion angles such as deep squats, lunges, or leg presses. Surgery is rarely needed and is reserved for specific structural problems with the kneecap, not for typical patellofemoral pain.
Non-surgical treatment
The foundation of treatment is rehabilitation:
- Hip and thigh strengthening with physical therapy, the single most effective measure, especially hip flexors and quads.
- Avoiding deep squats, lunges, leg presses, knee extensions or kneeling.
- Flexibility work, stretching the quads, hamstrings and Iliotibial band, and, for some, taping or a brace
- Footwear and running-form adjustments where relevant
Recovery timeline
Recovery is steady with a consistent program:
- Weeks 0 to 6Structured strengthening and activity modification. Expect gradual improvement.
- Weeks 6 to 12Progressive loading and a graded return to running and sport.
- OngoingMaintenance strengthening to keep symptoms from returning.
What patients commonly misunderstand
What patients are often surprised by:
- Rest alone rarely fixes it. Because patellofemoral pain is largely a strength and mechanics problem, resting helps short term but the pain returns with activity unless the underlying strength is addressed.
- It is rarely a surgical problem. Typical patellofemoral pain responds to rehabilitation. Surgery is reserved for specific structural issues, not for the common form of this condition.
