Exercises

Back or sitting position: push through the hollow of the knee of the stretched leg so that the M. Quadriceps tenses up (raising the stretched leg in the pushed through position) Squat (variations): stay in the bent position or simply sit on the wall, wide or narrow straddle or even lateral squat) Lunges For all exercises, as in general strength training, a proper execution, d. i.e. never push the knees out over the tips of the feet, push the buttocks out backwards in a knee bend and the upper body remains straight and the abdominal and back tension is maintained. You can find more exercises under: Exercises for the knee joint, knee school, exercises for a rupture of the inner and outer ligaments

Back or sitting position: Press down the hollow of the knee of the stretched leg so that the M. Quadriceps is tensed (raise stretched leg in pressed position)
Knee bend (variations): stay in the bent position or just wall sitting, width or narrow slide or even lateral knee bend)
Failure steps

Knee bend Lungee steps Bridging (supine position, feet upright, lift pelvis) Variation: alternately lift legs, push pelvis up and down, write numbers with stretched leg Prone position or 4-foot-stand: lift leg bent or stretched upwards. Exercises on the machines in the gym: leg press leg stretcher More exercises can be found under: Physiotherapy on the machines

Prone position or 4-foot-stand: Lift leg bent or stretched upwards.

Leg press
Leg Extensions

Bridging: Press the ball between the knees and then the legs together.
Lateral position: Lay the upper leg forward and press it into the floor.

Bridging (see above) with Theraband around the knees → Pressure outwards Side position: Lift leg upwards (several Wdh and passes) Wide knee bend For the muscles of the adductors and abductors, the exercises for the ischiocrural muscles and those for the M. Quadriceps are just as good, but can be intensified even further by the above-mentioned exercises.

Lateral position: lift leg upwards (several Wdh and passes)
Wide knee bend

Coordination training involves more specific control of the stabilizing muscles than strength training via proprioception. The exercises should be started in a simple execution and then increased in difficulty. They should also be done in relation to the patient’s ability to work under pressure.

exercises: Increase of the exercises after a few weeks: Lunges and knee bends on the uneven surface. Jumps from right to left with holding the leg axis. Jump on one leg on uneven ground.

Sprinting on large mat with sudden stop.

Move with the other leg in all directions (“8th writing”)
The therapist gives resistance stimuli to the pelvis, knee or foot and throws a ball to the patient so that the concentration is no longer on the knee.
Running on an Airex mat, trampoline, wobble board
At first normal walking to get used to the underground. Then the patient should stop walking on command and hold position. The next time the exercise increases, the patient should change to faster walking and then stop.

Lunges and knee bends on the uneven surface.
Jumps from right to left with holding the leg axis.
Jump on one leg on uneven ground.
Sprinting on a large mat with sudden stops.
Jumps on the mat or one-legged stand.

Practice legstand (important: keep knees slightly bent)
