Abstract: Purpose: To examine operative hip abductor strength, range of motion (ROM) and non-operative toe clearance and the associations between these variables in subjects three to fifteen months post total hip arthroplasty (THA). Secondarily, to provide a comprehensive perspective of the characteristics of this cohort. Methods: Our pilot study used cross-sectional, quantitative analysis to evaluate operative hip ROM, operative hip abductor and extensor strength, and toe clearance when walking in twelve subjects (n=12) three to fifteen months post- primary THA. Medical charts were reviewed retrospectively to help describe the physical characteristics of this population. Results: ROM and strength had a weak and non-significant correlation with toe clearance. With the removal of outliers that had clinically important pelvic obliquity, hip ROM continued to have a weak correlation to toe clearance of the non-operative side. However, peak hip abductor and extensor strength s correlation to toe clearance of the non-operative side was strengthened and displayed a trend towards a negative correlation. Conclusions: There is a trend towards a negative correlation between operative hip abductor and extensor strength and non-operative toe clearance post-THA. These results yield sufficient strength to warrant further investigation with a larger sample size and added complexity.
