Key result
Measurement of anterior-posterior shoulder translation using a knee laxity tester showed significantly larger AP-translation in patients with unilateral or multidirectional instability.
Why the study?
Does the use of a modified knee laxity tester reliably measure anterior-posterior translation in patients with shoulder instability compared to normal subjects?
Cross-Sectional

The Donjoy Knee Laxity Tester provides a reproducible method for quantifying anterior-posterior translation of the shoulder joint, distinguishing between stable and unstable shoulders.
May aid objective shoulder instability assessment; leaves open reliability for clinical decision-making without prospective validation.
We developed a simple method to measure the anterior-posterior (AP) translation of the shoulder joint: by positioning the Donjoy Knee Laxity Tester horizontally over the shoulder girdle, the AP translation was measured after applying a standardized sagittal force. Measurement of AP-translation during two tests on the same shoulder was reproducible with an intraclass correlation coefficient (ICC) of 0.996. In normal subjects the mean side difference was 0.6 mm, corresponding to a p-value of 1.00. In patients with unilateral instability AP-translation was significantly larger on the injured shoulder. Furthermore, the intraindividual differences in AP-translation were significantly larger in patients with unilateral instability than in normal subjects. Individuals with multidirectional instability had significantly higher values than any of the other groups.

Jørgensen et al. (1995) conducted a cross-sectional in Shoulder instability. Measurement of anterior-posterior translation using the Donjoy Knee Laxity Tester vs. Normal subjects was evaluated on Anterior-posterior (AP) translation of the shoulder joint. Measurement of anterior-posterior shoulder translation using a knee laxity tester showed significantly larger AP-translation in patients with unilateral or multidirectional instability.
