Total Knee Replacement (TKR) is one of the most commonly performed orthopaedic surgery(1). Immediate postoperative portable radiographs are performed after primary TKR in order to identify any potential complications and technical flaws. It also serves as a reference for comparison with subsequent radiographs. The aim of this study was to evaluate the clinical and economical value of these radiographs in TKR. It compares the quality of the portable radiograph, taken immediately post-operation, with in-suite radiographs taken 5-7 weeks post-operation


In this retrospective study, a consecutive series of 389 TKR patients from January-2011 to March-2015 were reviewed. Radiological evaluation consisted of assessing the beam angle and the exposure on the images. Implant positioning was also compared by measuring the anatomical axis to look for component alignment discrepancies.


The quality of the portable recovery room radiograph was overall inferior to the radiology suite radiograph regarding both beam angle and exposure. Component alignment discrepancies were also identified in the angle measurements between both types of radiographs.


Therefore, our study demonstrated that there is no clinical or financial value obtained from postoperative portable radiograph. Furthermore, Immediate recovery room radiographs should be avoided from being performed routinely and may only be used in cases where the surgeon is utilizing a new implant or technique. No external funding was provided for this study from any source.
