Introduction: In 1979, in his first book dealing with low-friction arthroplasty (LFA), Charnley highlighted the use of a cement restrictor. Breusch and Malchau described in 2005 the “second-generation cementing technique.”
The main objective of this study was to report on the clinical survival of 100 cases of Charnley femoral component implanted in 2007 and 2008 using a permeable and resorbable cement restrictor and a low-viscosity antibiotic-loaded cement.
The secondary objectives were to analyze the complications and side effects and the accuracy of the device positioning.
Material and methods: This was a monocentric retrospective review of a prospectively compiled database.
Diaphyseal restrictor was biodegradable and permeable to gas, blood, and fluids to avoid intramedullary over pression during cementation. The cement was a low-viscosity antibiotic-loaded cement.
Among 3555 patients, we selected the first continuous 100 cases of patients where we implanted the device.
Survival probability was computed according to Kaplan–Meier method.
Results: Mean follow-up was 6.55 ± 2.6 (range 1–11).
Considering femoral component revision as the endpoint, survival rate was 100%.
No patients died intraoperatively, none in the first month and the first year after surgery.
No early periprosthetic fractures have been reported.
Discussion: As described initially by Charnley, the use of a cement restrictor was highly recommended through the different generations of cementing techniques.
Hypotensive episodes and cardiac arrest have been reported during cement insertion.
In our series, we did not deplore any adverse effect related to the cementation.
Conclusion: Our study demonstrates a 100% survival rate of a cemented femoral component without adverse effects when using routinely a resorbable and permeable cement restrictor and a low-viscosity cement. Bone cement is still a fantastic ally for the surgeon and the patients.
