Baseline radiographs may be obtained portably in the recovery room but are limited due to portable technique and difficulty positioning the post-operative patient. Because visualization of the knee replacement in surgery is so complete and intraoperative complications are rare, some surgeons forgo portable studies. Instead they advocate initial one-month post-operative studies as more cost effective.7 These studies can be obtained in the radiology department with optimal patient positioning and exposure techniques, and therefore serve as the best baseline study.
Radiographs are evaluated for:
- Alignment and positioning of components
- Intraoperative fractures
- Cement technique
