The primary objective of the present study was to estimate the effectiveness of the new methods of physical rehabilitation for mountain ski athletes designed to optimize and accelerate restoration of their professional capabilities after arthroscopic plastic reconstruction of anterior cruciate ligament (ACL). This open controlled prospective study involved 26 alpine skiers aged from 18 to 25 who were recruited into the regular follow up program based at our Centre during the last 3 years. The athletes proved able to start balance training on the Biodex platform 4 weeks earlier than with the use of the conventional approach. These exercises were supplemented by the training of speed endurance on the Speed Courte tensor platform and Sky Teck ski simulators. Control studies were carried out on the 16th and 24th weeks of the rehabilitation period. Their results were compared with the results shown by the same athletes before injury. It was found that the early introduction of exercises designed to normalize proprioception into the rehabilitative treatment allowed the injured mountain ski athletes to restore the strength of femoral muscles and specific professional skills by the 4th month of the rehabilitation period. It is concluded that the combination of classical rehabilitative techniques with balance training, Speed Court training, and training on the alpine ski simulator makes it possible to begin special of alpine ski training on the snow 2 months earlier than with the use of conventkional methods.
