Background/Aim. The tibial slope is one of the most frequently cited
anatomical causes of anterior cruciate ligament trauma. The aim of this study
was to determine the possibility of direct measuring of the tibial slope of
the knee without prior soft tissue dissection in cadavers. Methods.
Measurement was performed on the two groups of samples: osteological and
cadaveric. The osteological group consisted of 102 matured tibiae and
measurement was performed: indirectly by sagittal photographing of the tibia,
and directly by a set of parallel bars. The cadaveric group consisted of 50
cadaveric knees and measurement was performed directly by a set of parallel
bars. The difference and correlation between indirect and the direct
measurements were observed, which included also measuring of the difference
and correlation of the tibial slope on the medial and lateral condyles.
Results. A statistically significant difference between the direct and
indirect method of measuring (p < 0.01) of 1° was found for the tibial slope
on the medial condyle, which is of no practical importance. Direct
measurement of the osteological and cadaveric groups of samples did not show
a statistically significant difference regarding the values of the tibial
slope on the lateral condyle (p > 0.05). However, the slope on the medial
condyle, as well as indirect measurement showed a statistically significant
difference (p < 0.01). Conclusion. By the use of a set of parallel bars it is
possible to measure the tibial slope directly without removal of the soft
tissue. The results of indirect, photographic measurement did not
statistically differ from the results of direct measurement of the tibial
slope.
