A close look at tibiofemoral rotation measurements.

The recent paper by Chung et al. [2] published in KSSTA caught our attention. Their study introduces a new laximeter to evaluate static rotational knee laxity termed “Rotatometer” and presents normative data as well as results for its reliability. Overall, it is interesting to see how rotational knee laxity measurements have received increasing interest in the area of orthopaedics, and especially in the field of anterior cruciate ligament (ACL) reconstruction surgery over the past few years [4]. Thus, we would like to congratulate Chung et al. [2] on their efforts to contribute to this emerging and relatively complex field.
