  1. This table shows a significant improvement of patients regarding EHL muscle strength testing in comparison to their preoperative data with significantly superior outcome among patients of group B compared to group A. there was a significantly higher frequency of patients who found improvement was good-to-excellent in group B versus group A regarding patients’ evaluation of improvement according to Odom’s criteria. Concerning patients’ satisfaction, there was a significant difference between patients of both groups in favor of group B
