The Contributions of the Multidisciplinary Management of Prosthesis Knee Infections in a Reference Center: A Retrospective Study About 52 Cases.Skin Coverage in a Reference Center: A Retrospective Study About 52 Cases

Study Overview
=================
Brief Summary
-----------------
Acute and chronic infection of knee joint prosthesis can have several outcomes, the most feared of which is trans-femoral amputation. In order to save the limb while maintaining function, the management of these infections involves several specialists. Orthopedic surgeons are on the front line for carrying out bacteriological samples as well as for changing the material when necessary. The infectiologists coordinate this care by supervising each of the interventions by an antibiotic therapy adapted to the germs and by ensuring the occurrence of adverse events related to the treatment. Plastic surgeons intervene when the skin cover of the knee is deemed to be precarious or when there is an identified loss of substance that could affect the prognosis of the prosthesis. The main objective of our study is to evaluate the success rate of skin coverage and functional recovery for patients cured of their infection. The secondary objective is the identification of risk factors for skin coverage in this population.
