Patellar position in weight-bearing radiographs compared with non-weight-bearing: significance for the detection of osteoarthritis.

CONCLUSION: In weight-bearing positions, the patella is positioned medially in the trochlear groove compared to supine non-weight-bearing positions. Therefore, this study suggests that the common occurrence of medial PF OA can generally not be detected on axial radiographs in supine non-weight-bearing positions and confirms the importance of imaging the PF joint in standing weight-bearing positions.
