“A noninvasive acceleration measurement for the pivot shift where the sensor was placed on the skin between the lateral aspect of anterior tibial tuberosity and Gerdy’s tubercle.”

Ahldén M, Hoshino Y, Samuelsson K, Araujo P, Musahl V, Karlsson J

[10]

“Our experience showed us that the use of KiRA accelerometer for quantitative measurement of the PS is both promising and reliable.”

Berruto M, Uboldi F, Gala L, Marelli B, Albisetti W

[11]

“It has been shown to overcome the weaknesses of other available devices and systems. Therefore, since it can be considered a new paradigm in the quantification of pivot shift test, we can recommend its routine use in clinical practice.”

Zaffagnini S, Lopomo S, Signorelli C, Marcheggiani Muccioli GM, Bonanzinga T, Grassi A, Raggi F, Visani A, Marcacci M

[12]

“The KiRA showed an excellent inter- and intra-tester repeatability and it can be used non-invasively in the office to quantify the Lachman test in case of suspected ACL injury and assess ACL surgical reconstruction results.”

Raggi F, Roberti di Sarsina T, Signorelli C, Marcheggiani Muccioli GM, Macchiarola L, Cucurnia L, Romagnoli M, Grassi A, Zaffagnini S

[13]

“ The use of a triaxial accelerometer to quantify the lateral tibial plateau acceleration in the pivot shift test appears to be relevant for detecting an ALL injury on a deficient ACL knee. These findings help provide clinical guidelines for more effective objective measures to diagnose ALL injury, and determine the most effective management for each patient.”

What our customers say about us

"Tibial acceleration parameters during the pivot shift test most closely correlated with the clinical grading performed by 12 expert surgeons."

Dr. Mattias Ahldén

University of Göteborg

"Based on our experience, the use of the accelerometer KiRA for quantitative measurement of the PS is both promising and reliable. It has the value of being easy to set up and easy to use in both the clinic and the operating room."

Dr. Massimo Berruto

Orthopedic Surgeon

"KiRA represents a valid non-invasive instrument able to quantify dynamic instability. Also for ambulatory assessment."

Prof. Nicola Francesco Lopomo

Biomedical Engineer

"A further application is the use fo KiRA as a teaching tool to instruct young surgeons to perform the PS test in a more standardized way, ultimately enabling comparison of clinical outcome following ACL reconstruction surgery."

Prof. Stefano Zaffagnini
