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