Recovery of the patient's confidence in his knee. Muscular work the quadriceps and hamstring co-contraction can be accentuated and intensified reasonable taking into account the phenomena of "ligamentisation". Proprioceptive activities become priority and gestures rehabilitation and endurance activities (walking, cycling, step, swimming in front and back crawl).
At period end, proprioception becomes dynamic bi and uni-podal with facilitating material.
- Development of neuromuscular control and proprioception (unstable platform, swing, trampoline ...)
- Cardiovascular exercise training (cycling, steps ...) start jogging on the flat and soft ground at end of period
- Dynamic activities in full power.
Phase 4 = REATHLETISATION: 4 th to 6 th month
objectives
From the 4th and 5th month, the tendon recovers its strength, the most important activities can be undertaken, both in power and endurance. Jogging is added to the disaster recovery program, the base remains, swimming, biking, muscular rehabilitation and work endurance, power and dynamic proprioceptive activities.
Means
- Athlétisation different muscle groups: press, weight bench ...
- Isokinetic work
- Dynamic work with jumps and direction changes smoothly
- Continuation with acceleration jogging, swimming like crawl with fins, bike ...
- Progressive physical rehabilitation activities
possible incidents
- Gene of the patella during flexion of the knee
- Inflammatory knee
- Patellar tendinopathy
Contraindication
- Physical and sports activities, and contact with pivot
Phase 5 = RESUMPTION OF SPORT: beyond the 6th month
objectives
Beyond the 6th postoperative month, the goal is to guide rehabilitation to sport specific practice. There is work to gradually bring the knee in a situation close to the sporting gesture. The duration of this step depends on the type of sport. For sports like football, rugby, judo, handball, dance, etc ... called sports hub, the resumption of training is between the 7th and 8th month. The resumption of the competition is between 9 and 12 months. In the 7th month, we can advise you to make a comparative isokinetic muscle balance knees to define muscle functional capacity to guide the sports preparation.
Means
- Comparative isokinetic test
- Intense muscle building
- Re-learn sport-specific gestures
- Adapted and progressive resumption of training sport practiced
- Specific sporting balance sheets.
possible incidents
- Muscle-tendon pathology sport.
Contraindication
- Anticipation of the resumption of the competition.
CONCLUSION
The ligament is a procedure performed in order to restore a knee suitable for sports. The objective will be fulfilled provided you follow the post operative rehabilitation. It is important to consider the possible different ligament neo the healing stages to preserve it.
The proposed protocol is the result of expert consensus and recommended by the National Health Authority (HAS). It is therefore indicative. It must be adapted to each type of knee, patient and performed surgery.
