The Patterson grading system is a method used to evaluate the severity of knee osteoarthritis based on radiographic findings. It categorizes the condition into four grades (I to IV), with Grade I representing minimal changes and Grade IV indicating severe joint damage, including bone deformities and significant cartilage loss. This system helps clinicians assess the progression of the disease and informs treatment decisions. It is widely used in both clinical practice and research settings.
