Summary
For assessing knee osteoarthritis, the Rosenberg view is sufficient. Adding the 20/10 view provides no significant difference in joint space measurements for weight-bearing knee radiographs.
Area of Science:
- Orthopedic imaging
- Radiology
- Osteoarthritis research
Background:
- Weight-bearing radiographs are standard for early knee osteoarthritis assessment.
- Full extension weight-bearing views are common, but other methods exist for evaluating knee joint space.
Purpose of the Study:
- To compare the effectiveness of Rosenberg and 20/10 views in measuring knee joint space.
- To determine if the 20/10 view offers additional diagnostic value when Rosenberg views are already obtained.
Main Methods:
- Eighty consecutive patients with knee pain underwent standing Rosenberg and standing 20/10 views.
- Knee joint space was measured for both right and left knees for each patient.
Main Results:
- No statistically significant difference was found between the 20/10 and Rosenberg views for either the left or right knee measurements.
- The study found no indication that the 20/10 view provides additional information beyond the Rosenberg view.
Conclusions:
- The Rosenberg view is adequate for routine radiographic evaluation of osteoarthritic knees.
- Routine inclusion of 20/10 views alongside Rosenberg views is not indicated for assessing knee osteoarthritis.
