Tibial slope significantly correlated with posterior tibial translation after PCL reconstruction

Recently published results showed flattening of the tibial slope in patients who underwent PCL reconstruction was associated with significantly higher remaining posterior tibial translation and a lower reduction of posterior tibial translation.
Using standardized stress radiographs, three blinded observers measured tibial slope and side-to-side difference of posterior tibial translation among 48 patients before and after PCL reconstruction, according to researchers.
Results showed a significant reduction in the mean side-to-side difference of posterior tibial translation at a mean follow-up of 103 months. Researchers noted a mean tibial slope of approximately 8° and 7.9° for operated knees and contralateral knees, respectively. Tibial slope had a statistically significant correlation with posterior tibial translation, as well as a significant correlation with the postoperative reduction of posterior tibial translation. Regarding tibial slope or the mean reduction of posterior tibial translation, researchers found no significant differences when they subgrouped findings according to number of operated ligaments. – by Casey Tingle
