Pain, quality of life, and functional outcomes of total hip arthroplasty in female patients with crowe type III-IV developmental dysplasia of hip: retrospective cohort study.

INTRODUCTION

The aim of this study was to investigate physical and psychosocial recovery including pain and quality of life measures, as well as lower limb functional out-comes in patients with Crowe type III-IV developmental dysplasia of the hip (DDH) who underwent total hip arthroplasty (THA) with subtrochanteric shortening osteotomy.

MATERIALS AND

METHODS

This study was conducted with a total of 45 female patients aged 32-65 with Crowe type III-IV DDH. Pre-op 30-second chair-stand Test (30-s CST), 6-minute walk test (6MWT) and Visual Analogue Scale (VAS) were assessed clinically, whereas Harris Hip Score (HHS), EuroQol 5-Dimension 5-Level (EQ-5D-5 L) scale, Forgotten Joint Score-12 (FJS-12), Hip disability and Osteoarthritis Outcome Score (HOOS), and SF-36 Quality of Life Scale (SF-36) scores were measured and recorded based on patient self reports. At least two years after the surgery, the same measurements were repeated in the patients.

RESULTS

At the mid-term follow-up, a significant increase was observed in the 30-s CST and 6MWT distance compared with the pre-op period (p < 0.01). Furthermore, statistically significant differences were observed in the VAS, HHS, EQ-5D-5 L, FJS-12, HOOS and SF-36 scores (p < 0.01).

CONCLUSIONS

An evaluation after THA with subtrochanteric shortening osteotomy in female patients revealed a significant improvement in functional performance and clinical scores. Also, it is an effective factor in improving joint function and quality of life in cases of severe DDH. Prospective studies are needed to understand the potential long-term effects of the procedure.
