Abstract
The paper presents our results with polymethylmethacrylate cement augmentation osteosynthesis around the knee joint and to discuss the advantages and complications encountered. We presented the benefits and limitations of cement augmented fixation constructs around the knee because of the lack of such studies that focus on this particular anatomical location. We consider that the cases described can contribute to a greater understanding when searching for solutions targeted on the knee defects. In conclusion, we find polymethylmethacrylate cement augmentation of implants to provide excellent fixation around the knee both for tumoral resections as well as for managing complex trauma cases.
