Comparative study on functional rehabilitation after artroscopic anterior cruciate ligament reconstruction - classical versus modern

The study assesses and compares the results obtained after applying a classical rehabilitation program and a modern rehabilitation program based on the integration of isokinetic systems to patients recovering from arthroscopic anterior cruciate ligament (ACL) reconstruction. The research involved 30 participants who were divided into two groups: one group followed a traditional rehabilitation program using proprioceptive exercises to restore range of motion (ROM) and muscle strength, and the other integrated isokinetic dynamometry (Biodex System 4 PRO) for personalized knee rehabilitation. The results showed that the group benefiting from the modern rehabilitation program achieved significantly greater improvements in muscle strength, joint stability and neuromuscular coordination, especially in terms of quadriceps peak torque and flexor-extensor muscle balance. Statistical analysis confirmed that the modern rehabilitation program provided faster and more consistent progress, demonstrating higher functional scores and reduced variability compared to the classical approach. However, the traditional program proved to be more effective in restoring relative hamstring strength. These findings highlight the advantages of isokinetic-based rehabilitation for the optimization of post-ACL recovery and support the need for individualized rehabilitation protocols. The study suggests that computerized dynamometry should be integrated into ACL rehabilitation programs to improve functional outcomes and reduce the risk of re-injury. Further research should explore their long-term benefits and impact on readiness for return to sports activity.
