NCT06308965

Brief Summary

During direct anterior approach (DAA) for total hip arthroplasty (THA), ligation of the lateral femoral circumflex artery and vessel is always conducted. However, this standardized procedure may jeopardize blood muscle perfusion and cause tenderness in the tensor fascia lata muscle. The investigators want to investigate whether blood vessel-sparing surgery is feasible, reproducible, and would alter outcomes following DAA THA. The surgical technique of the vessel-sparing procedure will be described and investigated in a prospective blinded RCT. The investigators hypothesize that the vessel-sparing technique is feasible in 60% of the patients. If these vessels were not sacrificed, the investigators expect the incidence of TFL tendinopathy to be lower.

Outcome Measures

Primary Outcomes (6)

  • a) Incidence of TFL tendinopathy

    Clinical examination to detect TFL tendinopathy

    one year follow-up

  • b-1) Patient-reported outcome 1: modified Harris Hip Score (HHS)

    modified Harris Hip Score (HHS) minimum (worse) score = 0 maximum (best) score = 44

    one year follow-up

  • b-2) Patient-reported outcome 2: Hip And Groin Outcome Score (HAGOS)

    Hip And Groin Outcome Score (HAGOS) minimum (worse) score = 0 maximum (best) score = 100

    one year follow-up

  • b-3) Patient-reported outcome 3: Forgotten Joint Score

    Forgotten Joint Score minimum (worse) score = 0 maximum (best) score = 100

    one year follow-up

  • b-4) Patient-reported outcome 4: Hip disability and Osteoarthritis Outcome Score (HOOS).

    Hip disability and Osteoarthritis Outcome Score (HOOS) minimum (worse) score = 0 maximum (best) score = 100

    one year follow-up

  • c) Component placement (x-rays)

    Using pelvic anteroposterior radiographs, with both legs internally rotated 15°: Acetabular version (Lewinnek method). Acetabular inclination Femoral alignment Under-sizing in case the femoral component is not touching cortical bone.

Masking Details
Participants will be blinded and randomized into two cohorts. The selection and randomization protocol is as follows: participants eligible for the study are requested to participate and informed by the study nurse. If the patient agreed to participate, informed consent is obtained, and the patient is included in the study. At that time, the study nurse uses a mobile randomization application (Random, Dublin, Ireland) to allocate them either to the 'standard' (sacrificing the vessels) or 'vessel sparing' DAA. Weighted randomization (1:2) is applied to compensate for a dropout of patients planned for vessel sparing surgery, but in whom the vessels were damaged unintendedly. In case a bilateral procedure will be performed, each side is randomized individually. Surgery will be performed by the surgeon. Data collection before and after surgery is collected by personal assistant who is unaware of group assignment.
