Planning
Weight-bearing radiography
Evaluation
The Kellgren-Lawrence scale has been recommended:[1]
| Grade | Description |
|---|---|
| 0 | No radiographic features of osteoarthritis |
| 1 | Osteophyte formation and possible joint space narrowing. The normal distances between the bones in the ankle are as follows:[2]
|
| 2 | Definite osteophyte formation with possible joint space narrowing |
| 3 | Multiple osteophytes, definite joint space narrowing, sclerosis and possible bony deformity |
| 4 | Large osteophytes, marked joint space narrowing, severe sclerosis and definite bony deformity |
Varus or valgus
Varus or valgus deformity can be measured with the frontal tibiotalar surface angle (TTS), formed by the mid-longitudinal tibial axis (such as through a line bisecting the tibia at 8 and 13 cm above the tibial plafond) and the talar surface.[3]
