[Measuring the cartilage thickness in the patellar gliding articulation with ultrasound--method and value].
An ultrasonographic method for standardized measurement of cartilage thickness in the patellar gilding articulation is presented. A total of 778 kneejoints was investigated. The measurements from 438 healthy kneejoints were analysed with regard to their correlation with sex, age, height and weight, and norm values wer calculated. These were compared with the measurements from 130 kneejoints with "retropatellar pain syndrome". It could be demonstrated that the cartilaginous covering of the patellar facies in "retropatellar pain syndrome" is significantly thinner on the whole (but in particular at the medial facet) than in the healthy kneejoint; after intra-articular chondroprotective treatment, this difference could no longer be demonstrated in 71 kneejoints which were followed up sonographically. The precision and the reliability of the measurement could be verified statistically, so that it is feasible to make a contribution not only to noninvasive diagnosis of retropatellar symptoms, but possible also to better appraisal of the efficiency of therapy measures.
