Ceramic-on-Ceramic Total Hip Arthroplasty and Squeaking: Influence of Component Design

This study is ongoing, but not recruiting participants.

The investigators want to examine if specific acetabular liner designs can be a contributing factor to audible squeaking associated with CoC bearings. The aim of the present study is to compare two different designed and well documented acetabular component systems with reference to squeaking and other noises from the hip.

Condition Intervention
Hip Arthrosis Device: THA with ABG II / Trident Device: THA with CLS / Trilogy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Participant)
Primary Purpose: Treatment
Official Title: Ceramic-on-Ceramic Total Hip Arthroplasty and Squeaking: A Prospective, Blinded, Randomized Clinical Trial of Influence of Component Design

Further study details as provided by Claus Varnum, Vejle Hospital:

Study Start Date: September 2011
Estimated Study Completion Date: November 2017
Estimated Primary Completion Date: November 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: ABG II / Trident Device: THA with ABG II / Trident
Surgery with total hip arthroplasty in the form of ABG II / Trident
Active Comparator: CLS / Trilogy Device: THA with CLS / Trilogy
Surgery with total hip arthroplasty in the form of CLS / Trilogy


Ages Eligible for Study:   18 Years to 64 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • All patients scheduled for uncemented THA under the age of 65 years.

Exclusion Criteria:

  • Patients with the following diagnoses of the hip: Recent femoral fracture, sequelae from older femoral fracture, acetabular fracture, and traumatic dislocation of the hip.
  • Patients without ability to give informed consent and/or willingness to participate in the follow-up protocol.
  • Severely impaired level of function due to other physical deficiencies than the hip.
  • Mental disability that could impair a patient's decision-making capability of giving informed consent and not enabling valid data collection.
  • Earlier primary THA or revision THA in the contralateral hip.
  • Pathology requiring another prosthesis concept than the below mentioned.
  • Body mass index greater than 35.
