We assessed differences in the incidence and appearance of the radiological signs of loosening of the cup for various types of design. This was an observational study based on hip registry data of 15,340 patients with 17,951 total hip arthroplasties collected over a period of 33 years in 49 hospitals in Central Europe. The threaded and the press-fit titanium cups showed significantly less aseptic loosening than the other systems. The direction of migration and the frequency of the radiological…

[Long-term results of the CLS acetabular cup in primary total hip replacement].
TLDR
The CLS acetabular cup shows good results at 16-year follow-up period and can be explained by insufficient bone support or bone resorption in the proximallateral part of the acetabulum in patients with developmental hip dysplasia, by low bone quality due to severe osteoporosis or by insufficient primary stability of the cup.
Mid-term Results of Hydroxyapatite-Coated Threaded Cup Implanted without Supplementary Supporting Screws
TLDR
The results suggest that second generation hydroxyapatite-coated threaded acetabular cups can be successfully implanted (and achieve excellent results) without the use of any supplementary supporting screws.
THA Using Metal-on-Metal Articulation in Active Patients Younger Than 50 Years
TLDR
Metasul bearings with cementless acetabular components remain promising in this high-risk younger patient population, however, additional followup strategies are recommended to determine any possible long-term deleterious effects associated with the dissemination of metallic ions.
Radiographic evaluation of a monoblock acetabular component: a multicenter study with 2- to 5-year results.
Revision hip surgery using the CLS expansion shell.
TLDR
The CLS expansion shell offers a viable alternative for revision hip surgery with lower bone quality, insufficient bone at the bottom and cavitary defects of the acetabulum.
Revision Hip Surgery Using the Cls Expansion Shell
TLDR
The CLS expansion shell offers a viable alternative for revision hip surgery with lower bone quality, insufficient bone at the bottom and cavitary defects of the acetabulum.
Primary total hip arthroplasty with a flattened press-fit acetabular component in osteoarthritis and inflammatory arthritis: a prospective study on 416 hips with 6–10 years follow-up
TLDR
This study shows that the flattened press-fit acetabular component creates adequate initial mechanical stability to allow osseous integration and that the cup can be safely used in both OA and IA patients.
Poor results of the cementless total hip arthroplasty with a nonporous coated acetabular component: AcSys Shearer Cup
TLDR
The intermediate radiological results with the AcSys Shearer Cup were unsatisfactory because of the high loosening rate, although the revision rate was low.
Eight- to ten-year clinical and radiographic outcome of a porous tantalum monoblock acetabular component.
Cementless Total Hip Arthroplasty With Metasul Bearings Provides Good Results in Active Young Patients: A Concise Followup
TLDR
The current survey at 13-year median followup has not yet indicated any long-term deleterious effects related to dissemination of metallic ions, and two senior authors continue to use 28- or 32-mm Metasul™ bearings with cementless THA components in young and active patient populations.

TLDR
Whereas improved cementing techniques have produced a marked reduction in the rate of femoral component loosening, the incidence of acetabular loosening has been only slightly influenced by such improvements, the future will show whether new technologies are able to solve the problems encountered with metal-to-metal combinations.
Acetabular reconstruction in developmental dysplasia of the hip: results of the acetabular reinforcement ring with hook.
Radiological demarcation of cemented sockets in total hip replacement.
TLDR
The fact that nearly 30 per cent of cases showed no demarcation even after 10 years supports the idea that there is no fundamental defect in the principle of employing cement in the acetabulum.
Poor results of the Freeman uncemented metal-backed acetabular component. Five-to-nine-year results.
TLDR
The Freeman acetabular component demonstrated a characteristic pattern of loosening on radiographs, and more than one-third of the remaining surviving cups showed loosening radiologically.
Loosening of the cup after low-friction arthroplasty in patients with acetabular protrusion. The importance of the position of the cup.
TLDR
Better results were obtained in moderate and severe protrusions reconstructed with bone grafting than in hips with mild protrusion which were not grafted, and the bone structure appeared normal after one year.
Fixation of the acetabular component: the case for cement.
TLDR
It seems that cemented total hip replacement is most suitable and perhaps is the right kind of operation for treating osteoarthritis of the hip for patients who are 60 years of age and older because the procedure is reproducible, the quality of arthroplasty is excellent, and it is durable, lasting as many as 15 years in 90% to 95% of the cases.

TLDR
Boneloc cement was associated with poor fixation due to inferior mechanical properties and the PLLA screws did not provide sufficient stability, and HA/TCP coating improved the fixation and the interface of porous cups.

TLDR
To find a favorable definition of loosening and to investigate the etiology of mechanical loosening of the cemented hip prosthesis, diagnostic criteria of contrast and radionuclide arthrography, bone scintigraphy, and roentgen stereophotogrammetric analysis (RSA) were evaluated.
Polyethylene wear from femoral bipolar neck-cup impingement as a cause of femoral prosthetic loosening
TLDR
This report clearly illustrates how impingement of a bipolar cup on the femoral neck can be a major source of polyethylene wear debris which induces femoral osteolysis and subsequent stem loosening.
More failures of uncemented acetabular screw-rings than of cemented polyethylene cups in total hip arthroplasties
Abstract The results of 498 total hip arthroplasties were prospectively studied. In 329 patients a cemented acetabular polyethylene cup was inserted. In 169 patients a threaded socket without cement…
