Summary

Injuries to the anterior cruciate ligament are common and are usually treated with reconstruction and subsequent rehabilitation. Many people succeed in return to sport (RTS), but not to the original level. Muscle strength factors can be assessed using isokinetic strength measurements, while the psychological readiness to return to sport can be assessed using the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) questionnaire. In this study, isokinetic strength testing and psychological testing with the ACL-RSI questionnaire 1 to 4 years after ACL reconstruction will be assessed. The study will be conducted at the Institute of Physical Medicine \& Rehabilitation at the Kepler University Hospital. The Biodex System Pro™, a medical device for measuring and training muscle strength, will be used for the isokinetic measurements. The research question is as follows: Is there a correlation between the results of the ACL RSI questionnaire and the results of isokinetic strength testing on the Biodex System 4 Pro™ in test subjects following ACL reconstruction?
