Degree of disability (GdB) in retropatellar arthrosis

Behind the abbreviation “GdB” is the term “degree of disability”. GdB is defined as a condition in which the mental, spiritual and physical abilities and functions of those affected are impaired to an extent that does not correspond to their age. By definition, a period of 6 months is decisive.

The GdB is anchored in paragraph 2 of the Social Security Code IX and is used to assess the extent to which an illness is considered a disability. The whole is based on a specific score system in which a gradation in 10 steps takes place. As soon as more than 20 points are reached, one can speak of a disability.

With regard to retropatellar arthrosis, the points are distributed after surgical treatment in the form of a prosthesis, depending on the movement restriction. Movement restriction refers to the ability to bend (flexion) or stretch (extension) the knee. If a partial prosthesis was inserted, only 10 points can be reached.

20 to 30 points are considered a guide value for a total prosthesis. However, it is also important whether only one or both sides are affected: On one side 0-10P. is counted for slight movement restrictions, 20P.

for moderate restrictions and 30P. for severe restrictions. For bilateral cases, 20P.

applies according to the severity level. 40P. and 50P.

If the movement restriction is missing despite proven cartilage damage, 10-30P. can be assigned for the unilateral variant and 20-40P. for the bilateral variant.
