Claus Varnum, Vejle Hospital
ClinicalTrials.gov Identifier:
NCT01420900
First received: August 19, 2011
Last updated: June 18, 2014
Last verified: June 2014
  Purpose

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.

Accepts Healthy Volunteers:   No
Criteria

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.
