Abstract
The error in measurement of JSW caused by variation in IMD in serial radiographs of normal knees can be as large, or larger, than the mean rate of 12-month joint space narrowing (JSN) in OA knees. MTP alignment and replication of alignment in serial knee films are required for accurate determination of JSN in OA knee.

In normal knees, joint space width (JSW) is correlated with the intermargin distance (IMD), a measure of medial tibial plateau alignment. Variations in IMD explain variability in JSW in serial radiographs
