Slocum's Test

Welcome to Vrije Universiteit Brussel's Evidence-based Practice project. This space was created by and for the students in the Rehabilitation Sciences and Physiotherapy program of the Vrije Universiteit Brussel, Brussels, Belgium. Please do not edit unless you are involved in this project, but please come back in the near future to check out new information!!

Search Strategy

A search was done on PUBmed, web of knowledge, article database, the library, google books and google scholar to find some interesting evidence based articles about this subject. Different terms were used, such as ‘slocum test knee’, ‘anterolateral rotatory instability knee’ and ‘ALRI test’. 14 Results were found on PUBmed but no full texts were available. On web of knowledge, only 3 results were found but none of them contained interesting information and article database showed no results. Only two articles of ‘The Journal of Bone and Joint Surgery’ were found on google scholar, where they described the technique of the Slocum’s test. Unfortunately no articles were found concerning the reliability of instability tests of the knee. Interesting information was also found in several books in google books and the library. Later a search was done in google for ‘Slocum’s test’ to read some extra information about it and then a search on youtube for some videos of the technique.

Definition/Description

The Slocum’s test (1976) represents a modification of the Anterior Drawer test (4.) which tests anteromedial rotary instability (AMRI) and anterolateral rotary instability (ALRI) of the knee. (5.)
The anterior drawer test evaluates the anterior cruciate ligament. When inserting an internal or external rotation to this test, anterolateral and anteromedial rotary instability can be evaluated.

Clinically Relevant Anatomy

Following structures may be involved when the test comes out positive:
-Anterolateral: Anterior and posterior cruciate ligament, posterolateral capsule, arcuate – popliteus complex, lateral collateral ligament and iliotibial band.
-Anteromedial: Anterior cruciate ligament, medial collateral ligament, posterior oblique ligament, posteromedial capsule. (6.)
