Finally the most widely used score to evaluate
impact on the quality of life is the
SF-36
, and
particularly its short version, the
SF-12
[18].
This self-administered questionnaire is used in
all medical specialties. In joint disease it is
generally used in combination with a specific
questionnaire.
It consists of two sub-scores: a “physical”
score and a “mental” score. Calculation of the
score is complex, however, it may be
performed on-line.
New KSS
Patient evaluation is difficult due to diversity of
age, lifestyle, sports participation and psycho
social context. Previous scores are now mostly
obsolete, and it is often necessary to combine
several scores, complicating the task of the
surgeon.
For this reason, the Knee Society committee
revised the KSS in 2012 [19-21]. This score
remains the most widely used in the evaluation
of patients with knee osteoarthritis. A new
section called the “subjective component” was
added. The knee score is now called the
“objective” component. The new component is
a self-administered questionnaire, which
provides the reliability of patient reported
outcomes. It evaluates two new areas:
expectations and patient satisfaction. Function
is evaluated not only in activities of daily living,
but also in sports and recreational activities.
