Radiological study of alignment after total knee replacement. Short radiographs or long radiographs?

D V Patel et al. Int Orthop. 1991.

Abstract

The axial alignment on short and long radiographs was measured in 50 knees in 34 patients who had undergone posteriorly stabilised (Insall-Burstein) condylar knee arthroplasty. A mean difference of 1.6 degrees was found when the tibiofemoral angles were compared on short and long radiographs. Short radiographs are probably adequate for routine assessment of knee replacements in a busy out-patient clinic, but for accurate scientific studies the long radiographs are preferable.
