Functional results in periacetabular osteotomy: is it possible to obtain a normal gait after the surgery?

Abstract

Introduction

Gait analysis is one of the poorly understood dimensions of the functional results obtained after periacetabular osteotomy (PAO) due to dysplasia of the hip.

Materials and methods

Spatiotemporal parameters as well as coronal and sagittal plane kinematics and moments were compared among three demographically similar groups of subjects: (i) 23 patients with excellent results according to the Harris Hip Score (HHS) (mean 6.6 years of follow-up); (ii) 12 patients with good and fair results according to the HHS (mean 9.3 years of follow-up); and (iii) 35 asymptomatic controls.

Results

50% of the analysed sagittal plane kinematic parameters were significantly better (p<0.05) in the control group not only for the hip joint but also for the ipsilateral knee and ipsilateral ankle. A vast majority of the other evaluated gait parameters resulted similar among the groups (p>0.05).

Conclusions

In our experience, most of the gait parameters after PAO are close to those observed in control subjects; however, the obtained pattern cannot be classified as a completely normal gait. The excellence in terms of functional results seems not to be determined by the achievement of this theoretical goal.
