Knee Extension Syndrome
Your knee pain is located superior to the patella in the quadriceps or quadriceps tendon. Medial diagnoses might include quadriceps strain or quadriceps tendonitis. These symptoms are usually aggravated with high impact activities, such as jumping and running.
The Sports Physiotherapist talks about an article indicating risk factors for developing patellofemoral pain syndrome and I believe this diagnosis would be one of the diagnoses that falls under patellofemoral pain syndrome. The risk factors are:
- Decreased knee extension strength
- Decreased quadriceps and gastrocnemius flexibility (this is the most important risk factor related to this specific diagnosis)
- Increased navicular drop (your foot becomes a flat foot in standing, but isn’t when sitting)
- Increased knee valgus during landing
- Decreased vertical jump performance

- Improve the flexibility of the quadriceps without aggravating the pain.
- Improve gluteal and hamstring activation and strength.
