Values are mean values with standard deviation in parenthesis. Comparison between the affected/operated and non-affected/non-operated side (Paired-Samples T-Tests); comparison between the affected/operated/non-affected/non-operated side and healthy controls (Independent-Samples T-Tests). HKS = Hip-Knee-Shaft-Angle; FO = Femoral Offset; NSA = Neck-Shaft-Angle; HKA = Hip-Knee-Angle
a significant difference between the affected and non-affected / operated and non-operated side
b significant difference between the preoperative and postoperative value
c significant difference to the healthy controls
