Background
- Major cause of anterior knee pain (especially in women)
- Pain comes from contact of posterior surface of patella with the femur
- 3 major causes:
- 1. Focal trauma (least common)
- 2. Overuse
- 3. Abnormal patellar tracking (due to quadriceps weakness)
Clinical Features
- Gradual onset of unilateral, anterior knee pain, nonradiating
- Pain worsened by prolonged knee flexion ("moviegoer syndrome") and stair climbing
- Patellar grind test
- Press patella away from femoral condyles while pt contracts the quadriceps
- Sudden patellar pain and relaxation of the muscle is positive test
- Press patella away from femoral condyles while pt contracts the quadriceps
Treatment
- Conservative therapy (w/ emphasis on physical therapy and strengthening)
