About this trial
Residual limping after total hip arthroplasty is empirically associated with the use of lateral approach but has been reported in litterature even with the use of posterior approach. The purpose of this clinical trial is to compare the risk of residual limping one year after total hip arthropasty between lateral and posterior approach.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Primary unilateral osteoarthritis of the hip scheduled for total hip arthroplasty.
Ability to understand and write swedish.
Disqualifiers
Impaired funktion of the contralateral hip or knees causing limping.
Neuromuscular diseases

Postoperative discrepancy in femoral offset exceeding 25% of the femoral offset of the contralateral hip.
Trial design
Design model
Parallel
Treatments tested in this trial
Lateral approach
Procedure/SurgeryTotal hip arthroplasty performed through a lateral surgical approach (Gammer)
Posterior approach
Procedure/SurgeryTotal hip arthroplasty performed through a posterior surgical approach (Moore)
Treatment groups
580 Participants
are divided into 2 treatment groupsGroup A: Lateral approachActive comparator 1 intervention
Group B: Posterior approachActive comparator 1 intervention
Trial outcomes
Primary outcomes
1
Trendelenburg sign as binary variable (positive/negative)
Trendelenburg sign negative if the pelvis remains horisontal while standing only on the operated leg with both arms in anatomical postion. If the pelvismcannot be kept horisontal and tilts towards the kontralateral hip the Trendelenburgs sign is regarded as positive.
