Thessaly Test

Execution:

1. Patient is standing on the affected leg, which is flexed to 20°
2. The patient holds on to the examiner’s hands and rotates over the tibia 3 times towards each side (medially+laterally)

 

Positive Outcome: The patient experiences pain in the knee joint line during the rotations

Comment: The Thessaly Test was considered very promising after the first RCT by Karachalios et al. (2005). However, accuracy in this study is overrated dure to spectrum bias (controlled vs. Healthy group). The results from the RCTs from Goossens et al. (2015) and Blyth et al. (2015) have shown that the Thessaly test is not better and possibly inferior to other existing tests for meniscus lesions.
