Patella Femoral Syndrome
Discomfort at the front or inner knee area, which is aggravated by activity or by extended time sitting (such as at a desk chair or theater seat) with knees bent.
The main symptoms of patellofemoral pain syndrome are knee pain and chronic inflammation, especially when sitting with bent knees, running, squatting, jumping or using the stairs. The knee may be mildly swollen.
Occasional knee buckling/giving way may occur suddenly and unexpectedly due to lost quadriceps strength. Catching, popping, or grinding when walking or with knee movement is common. Pain tends to come on gradually and symptoms may increase over time.
Treatment is aimed to improve the alignment of the patella during contraction of the thigh muscle:
- Strengthening the inner quadriceps muscle
- Stretching and strengthening the quadriceps and hamstring muscle groups
- Bracing with patellar centering devices may be needed
- Icing, use of anti-inflammatory drugs and activity modification can help reduce irritation and pain
