Open the CIPO recordAbstract From the Canadian patent
A non-invasive system for quantitatively analyzing knee kinematics in three dimensional motion is described. The system includes a harness for securement about a knee and which has three magnetic sensors each secured to a sensor support. The sensor support is maintained substantially in a fixed relationship. At least some of the sensors are displaceably adjustable by adjustment members for contact with precise knee anatomy locations. A transmission network interconnects the sensors to respective inputs of a program analyzer for treating data signals from the sensors when the knee is in motion for quantitative evaluation of the kinematics of the knee while in motion.

Why it's free to use
- Filed November 1, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 1, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 1, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
