Muscular strength and function after total hip arthroplasty performed with three different surgical approaches: one-year follow-up study

Patients operated via the DLA had reduced muscular strength, HOOS-PS scores and higher pain scores than those who underwent PA and AA type surgery. The non-operated leg was significantly stronger than the operated leg in all groups 6 months postoperatively and this persisted up to 12 months postoperatively for the DLA and AA groups. Clinical Trial Protocol number: ClinicalTrials.gov (NCT01506024).
