Monoblock cups in cementless total hip arthroplasty (THA) do not show improved outcomes. This review found similar polyethylene wear, migration, osteolysis, and loosening rates compared to modular components.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Engineering
  • Arthroplasty Research

Background:

  • Monoblock acetabular components in cementless total hip arthroplasty (THA) are theorized to reduce osteolysis and polyethylene wear.
  • Evidence supporting these mechanical advantages is limited.

Purpose of the Study:

  • To systematically review controlled trials comparing monoblock and modular uncemented acetabular components in primary THA.
  • To evaluate differences in polyethylene wear rate, cup migration, acetabular osteolysis, and aseptic loosening.

Main Methods:

  • Systematic search of Medline, Embase, and Cochrane databases for controlled trials.
  • Inclusion of studies meeting "best evidence" criteria (Cochrane checklist ≥50% or Newcastle-Ottawa ≥75%).
  • Analysis of seven high-quality publications.

Main Results:

  • No significant differences were found in polyethylene wear rate, cup migration, or aseptic loosening between monoblock and modular components.
  • No convincing evidence supports reduced acetabular osteolysis with monoblock cups.

Conclusions:

  • The hypothesized benefits of monoblock cups regarding wear and failure rates are not supported by this best-evidence systematic review.
  • Polyethylene wear, cup failure, and acetabular osteolysis rates were similar between monoblock and modular implants.
  • Implant selection for cementless THA should consider factors beyond the monoblock versus modular design.
