Fulkerson and Shea reported a grading scheme for classifying patellofemoral malalignment in patients with chronic patellofemoral pain. The authors are from the University of Connecticut.
Parameters:
(1) patellofemoral malalignment
(2) articular lesion
|
Patellofemoral Malalignment |
Articular Lesion |
Type |
|
subluxation only |
no articular lesions |
IA |
|
|
minimum chondromalacia |
IB |
|
|
osteroarthrosis with or without a history of dislocation |
IC |
|
subluxation and tilt |
no articular lesion |
IIA |
|
|
minimum chondromalacia |
IIB |
|
|
osteoarthrosis |
IIC |
|

no articular lesions |
IIIA |
|
|
minimum chondromalacia |
IIIB |
|
|

IIIC |
|
none |
no articular lesions |

|
|

where:
• Minimum chrondromalacia corresponds to Grade 1 or 2 articular damage (see arthroscopic grading scheme for degeneration of articular cartilage).
• Osteoarthrosis corresponds to Grade 3 or 4 (large areas of fibrillation or exposed bone.
