Comparable Results With Porous Metal Augments in Combination With Either Cemented or Uncemented Cups in Revision Hip Arthroplasty: An Analysis of One Hundred Forty-Seven Revisions at a Mean of Five Years

Comparison of the Primary Stability of Porous Tantalum and Titanium Acetabular Revision Constructs

“…Aseptic loosening has been reported to be the major reason for THA revision [2,18], and the frequently associated osteolytic defects that result from particulate debris and component wear can present a significant surgical challenge [2,19,20]. Revision THA consequently has a greater incidence of failure than primary THA because of the compromised soft tissue, bone loss and increased complexity of the procedure.…”

“…In RTHA in particular, tantalum components have been reported to have excellent results in complex cases, even with large bone deficiencies [21,37,38]. The ancillary use of porous tantalum augments as buttresses in cases of insufficient acetabular rim support has also been reported to have superior results [2,39,40]. Konan et al reported a 96% survivorship of the TM acetabular component and good functional outcome at a mean 11 year follow up in patients with Paprosky 11 and 111 defects [41].…”

“…One study evaluating 146 Pinnacle Gription cups, 1 of which was used in combination with an augment, showed good short-term results after RTHA [42]. In addition, studies with Gription augments used with various other cup types have shown good functional results [2]. However, there have been recent reports of studies that used other titanium components of different composition and manufacture, such as Trabecular Titanium and Tritanium ® [43].…”

“…Total hip arthroplasty (THA) is a highly successful surgical intervention that is being performed with increasing frequency in cases of advanced osteoarthritis, and in patients of decreasing age [1]. The increased incidence of primary THA is accompanied by a corresponding increase in revision THA with the associated concerns of diminished bone quality, bone loss and compromised soft tissue [2]. Earlier interventions that addressed these concerns included the use of large structural allografts that had mixed results with loosening and migration rates of up to 70% [3].…”

The direct anterior approach for acetabular augmentation in primary total hip arthroplasty

“…Most of the research has focused on tracebular metal [26] with Whitehouse et al [27] reporting a 92% survivorship after 10 years of trabecular metal augments. Mahmous et al [28] , using both trabecular metal and GRIPTION, found that metal augments are compatible with both cemented polyethylene cups and uncemented metal acetabular cups with survivorship over 95% for each. However, there was no comparison between the 2 augments in this study and, unfortunately, there is no peer-reviewed research thus far on GRIPTION [25] , despite that multiple implant manufacturers have now developed augments with similar shape and purpose.…”
