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., conditionsModule conditions: Tensor Fasciae Latae Syndrome, conditions: Arthroplasty Complications, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: SINGLE_GROUP, interventionModelDescription: This is a monocentric prospective randomized blinded clinical trial during a period of minimal 3 years or until 150% of sample size is included (100 patients)., primaryPurpose: TREATMENT, maskingInfo masking: TRIPLE, maskingDescription: 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., whoMasked: PARTICIPANT, whoMasked: CARE_PROVIDER, whoMasked: INVESTIGATOR, enrollmentInfo count: 300, type: ESTIMATED, armsInterventionsModule interventions name: Vessel technique, outcomesModule primaryOutcomes measure: a) Incidence of TFL tendinopathy, primaryOutcomes measure: b-1) Patient-reported outcome 1: modified Harris Hip Score (HHS), primaryOutcomes measure: b-2) Patient-reported outcome 2: Hip And Groin Outcome Score (HAGOS), primaryOutcomes measure: b-3) Patient-reported outcome 3: Forgotten Joint Score, primaryOutcomes measure: b-4) Patient-reported outcome 4: Hip disability and Osteoarthritis Outcome Score (HOOS)., primaryOutcomes measure: c) Component placement (x-rays), secondaryOutcomes measure: Vessel sparing succesfull, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Ziekenhuis Oost-Limburg, city: Genk, state: Limburg, zip: 3600, country: Belgium, contacts name: Frans-Jozef Vandeputte, M.D., role: CONTACT, geoPoint lat: 50.965, lon: 5.50082, hasResults: False
