Introduction: The aim of study was to analyze the influence of bilateral anterior cruciate ligament reconstructions on life quality of patients and their return to sports activities.
Material and methods: Thirty-two operated patients took part in this survey during the period of ten years. There were 5 women and 27 men, their average age being 30.46 years (19-55). The participants answered a modified Knee Injury and Osteoarthritis Outcome Score questionnaire set and gave data about preoperative and postoperative periods.
Results: The participants' age and parameters of Lysholm scale did not correlate significantly with the subjective level of physical activity after the second knee surgery. After the first anterior cruciate ligament reconstruction, 4 participants (12.5%) did not return to trainings, while 28 did (87.5%); 8 patients (25%) did not return to competitions and 24 of them (75%) achieved the competition level of sports activities. After the anterior cruciate ligament reconstruction of contralatera knee, 6 (18.8%) did not return to trainings, while 26 (81.3%) did; 15 patients (46.9%) did not return to competitions, while 17 (53.1% continued to compete without restrictions. The average values of questionnaire scores were between 95.1-98.2 points. Discussion and
Conclusion: Resuming the same or higher level of sports activitie., after the first reconstruction is one of the preconditions for the same injury of another knee. An athlete looses more than two and a half years of competitions on average. Operations of additional meniscu ruptures do not play a crucial role in restitution of sports activities Although we achieved good operative results, only every seconc athlete with bilateral injury has returned to sports activities withou restrictions after the bilateral anterior cruciate reconstructions.
