1. Risk kinds of sport:

Often with sportsmen with jump stress and kinds of strengthening sport (e.g. far high jump, Volleyball, basketball, Gewichtheben, ballet, tennis)

2. Anatomy:

The tendon of the kneecap (Ligamentum patellae) begins at the lower point of the kneecap and runs from there from further to the lower leg. It represents thus the stringy extension of the front thigh musculature.

3. Function:

The patella tendon serves the power transmission of the front thigh musculature on the lower leg with aspect ratio and diffraction of the knee.

4. Injury mechanism:

- it comes to inflammations and fiber tears of the patella tendon due to degenerative overstressing in the course of long lasting sporty jump stress

5. Symptoms:

- Pain within the range of the tendon during stress (for example knee bends with weights) or with jumps
- Pressure pain within the range of the tendon beginning at the lower Patellarand

6. First measures:

- Reduction of the sporty load (jumps)
- in the acute phase cooling the range concerned

7. Diagnostics:

- orthopedic investigation
- Ultrasonic

8. Therapy:

a) Conservative therapy
- anti-inflammatory medicines
- Injections (no Kortison, because thereby the tear danger is increased)
- train on soft underground
- ESWT (extrakorporale shock wave therapy)
- Ultrasonic
b) Operational therapy
- Distance of the ignited piece of tendon

9. Physiotherapy / rehablitation:

- Electrical therapy
- Transverse frictions
- Cooling/heat applications depending upon phase
- Stretch of the front thigh
- stabilisation exercises for the leg axis
- Ttraining the musculature of the thigh back
- Ttape dressingsduring load
- Training therapy (bend-inherit-toned)

10. Prevention:

- Reduction of the load on hard underground
- Stretch exercises strengthen (thigh front)
- Thermic protection at the knee carry (bandage)
