Cemented hip stem fixation is advisable for older patients and associated with a low revision risk;
Cemented hemiarthroplasty in femoral neck fractures results in low risk for periprosthetic fractures (PPF) and is cost-effective;
Good long-term survivorship for cementless THA in young patients;
Cemented TKAs show better survival rates compared to cementless TKAs.

Summary

Data extracted from arthroplasty registers (Europe, US, Australia) indicate better survival rate in the short and long term when using cemented implants in Total Hip Arthroplasty (THA) & Total Knee arthroplasty (TKA).

Registers

Germany, The Netherlands, Sweden, Norway, UK, USA, Australia

Relevant questions

Survival rate: cemented or cementless?
Mortality: does cementation affect mortality?
Post-op infection: is AB-loaded cement worth it?

Study results

Survival rate

Cemented TKA better than cementless TKA.
Cemented hip stem advisable for older patients (better survival rate than cementless stems).
Cemented Hip Hemiarthroplasty (HA) leads to a lower risk of periprosthetic fractures.

Mortality

No increased mortality with cemented HA.

AB bone cement

Key points

Cementation is a good choice in TKA, HA and THA (old patients)
Bone cement implantation syndrome (BCIS) is a problem which can be controlled
Post-op infection is reduced using AB-loaded bone cement
