PURPOSE OF THE STUDY:
Increased tibial slope facilitates anterior translation of tibia relative to the femur, thereby increasing the load on both the native and replaced anterior cruciate ligament. This study aims to retrospectively review the posterior tibial slope in a cohort of our patients after the ACL reconstruction and revision ACL reconstruction. Based on the results obtained by measurements, we aimed to confirm or disprove the claim that the increased posterior tibial slope is one of the risk factors of the ACL reconstruction failure. Another aim of the study was to assess whether there are any correlations between the posterior tibial slope and basic somatic parameters (height, weight, BMI) or the patient s age.

MATERIAL AND METHODS:
The posterior tibial slope was measured retrospectively on lateral X-rays of 375 patients. There were 83 revision reconstructions and 292 primary reconstructions performed. The patient s age at the time of injury, height and weight were recorded and the BMI was calculated. The findings were then statistically analysed.

RESULTS:
The mean posterior tibial slope in 292 primary reconstructions was 8.6 degrees, whereas the mean posterior tibial slope in 83 revision reconstructions was 12.3 degrees. The difference between the studied groups was statistically (p
