Knee Scoring Scale II of Kettelkamp and Thompson

Kettelkamp and Thompson developed scales for evaluating patients after knee surgery. The authors are from the Universities of Indiana and Arkansas.

Parameters (same as in Scale I, most with different weights):

(1) pain with activity

(2) handling stairs

(3) synovial thickening

(4) flexion contracture

(5) anterior drawer

(6) lateral collateral ligament stability

(7) pain on rotation

Parameters (other):

(8) activity level

(9) walking on rough ground

(10) distance walked

(11) posterior drawer

total score =

= SUM(points for all 11 parameters)

Interpretation:

• minimum score: 0

• maximum score: 97

• The higher the score, the greater the functional level.
