Abstract

Pain following total hip arthroplasty (THA) and surface arthroplasty (SRA) remains a significant source of patient dissatisfaction. Two hundred twenty-four SRA and 196 THA patients completed a pain drawing questionnaire and postoperative radiographic measurements of component positioning were performed. In the SRA cohort, 11 of 21 patients (52%) with acetabular uncoverage of ≥5. mm versus 43 of 147 (29%) with acetabular uncoverage of ≤4.9. mm reported groin pain (P=03). In the THA cohort, an increased distal-third canal fill ratio and a lower canal calcar ratio trended towards a higher incidence of thigh pain (P=10 and .06), while a decreased mid-third canal fill ratio was associated with increased severity of thigh pain (P=04). This study identifies associations between radiographic findings and pain following THA and SRA.
