Study Summary

Total knee replacement surgery (TKA) is a treatment for advanced tibial-femoral osteoarthritis. This intervention is justified in case of significant discomfort and failure of medical treatment. It aims to replace the native internal and external femoro-tibial joints with a joint between a femoral implant and a tibial implant.

Implants can be cemented or cementless. The longevity of these implants depends among other things on the quality of the bone fixation of the implants. It is therefore essential that this fixation be evaluated. The advantages of an uncemented TKA are the preservation of bone stock, the absence of wear by cement debris and prolonged fixation thanks to osseointegration. These characteristics are all the more interesting in a young population.

Numerous studies have been carried out on the survival of TKA with and without cement. The results found are not unanimous and mainly concern the survival of the implants and the presence of radiological signs of loosening. In addition, no study has evaluated the results of TKA with or without cement implanted using robotic assistance. The precision provided by the robotic system could improve the results of these uncemented implants.

Very few studies are interested in the functional results according to the cementation or not of TKA. And most of these studies do not have a high level of methodological evidence.

We would like to prospectively evaluate the functional results, survival, as well as the rate of radiological border after TKA with or without cement posed with robotic assistance, in the short and medium term.
