Outcome measures
Primary outcome
Comparing the initial and long-term survival of the cemented and uncemented ABG prosthesis.
The primary endpoint will be defined as revision of the ABG THA for any kind. Revision for prosthesis
related reasons (RPR) will be defined as revision for mechanical aseptic loosening, wear of the implant, breakage or instability due to implant failure that required surgical arthroplasty of femoral or acetabulum components.
Secondary outcome
Comparing the initial and long-term clinical results of the cemented and uncemented ABG prosthesis.
o Standard clinical parameters (Physical examination(2.4) and Questionnaires (2.5)) will be evaluated and compared between both groups.
Background summary
Total hip arthroplasty (THA) is often the end-stage treatment for severe osteoarthritis. Ageing and obesity are triggering factors for a higher number of patients with osteoarthritis. Osteoarthritis and overall joint pain is most located in the knees and hips. With the
obesity and ageing in mind the incidence of a THA operation will be increasing, also in younger patients. Because of the younger aged patients who receive a THA the survival of the femoral component and articulations must be sufficient to give al long lasting quality of life and a minimal chance of revision of
the THA. There are two major ways to implant a THA, uncemented and cemented. The use of
uncemented THA is increasing over de last years, but there is till so far no superior method. The Anatomic Benoist Girard (ABG) THA is made of a titanium alloy and has an anatomical femoral shape with only proximal fixation, the femoral component can be coated with hydroxyapatite for uncemented
fixation. In comparison to other femoral stems the ABG femoral stem has got a higher ‘shoulder’ for good contact and fixation on to the cancellous metaphyseal bone
and a smaller diaphyseal region to avoid diaphyseal fixation. Due to this specific geometry the physiological load transfer in both the acetabulum and femur is simulated. Fixation of the femoral and acetabular component can be uncemented
and cemented dependent on the surgeons experience or the intensity of the use of the THA. There is no difference in geometry
of the uncemented and cemented femoral components. The ABG THA has been widely used from 1989 in Europe and is also investigated in several studies. The study of Nourissat et al. showed a survival with revision as endpoint of 97.6%.
Nevertheless this was a study with a minimum 8-year follows up and had only investigated uncemented ABG THA. There are no studies comparing the long time follow up and survival, 10-years or more, of the
uncemented and cemented ABG THA. This clinical study is a benefit for patients who receive an ABG THA, if the survival rate turns out to be good for both uncemented and the cemented ABG THA in comparison with other prostheses, it would justify further use of both types of the ABG THA.
Study objective
We hypothesize that there is no difference between the survival and follow of the uncemented and cemented ABG THA.
