Abstract

Introduction: The principal aim of our study is to investigate risk factors for lateral trochanteric

pain (LTP) after direct anterior approach (DAA) primary total hip arthroplasty (THA).

Methods: A retrospective case control study was developed from 542 patients who underwent

primary THA over a 9-year period to form two patient cohorts. Two hundred and seventy-one

patients diagnosed with LTP were matched with 271 controls. Chart review revealed patient

demographics, surgical approach, and femoral components utilized. Change in limb length and

offset were assessed through preoperative and postoperative radiographic measurements.

Results: There was a higher proportion of current or former smokers in the LTP group (34.5%

vs 21.74%, p=0.003). There was no significant difference in use of high offset stems vs. standard

offset stems between groups (15.9% vs. 18.5%, p=0.494). However, the LTP group had

significantly higher increase in both femoral offset (+3.55mm vs +1.79mm, p<0.001) and total

offset (+0.16mm vs -1.16mm, p=0.031) in comparison to controls.

Conclusion: An increase in total offset, femoral offset, and smoking history are factors associated with LTP after DAA primary THA.
