Multiple Test Knee Joint Analysis

A method includes obtaining test data during a plurality of joint tests, the test data being indicative of respective motion during each test, each test being implemented by a robotic testing apparatus that applies, during each test, a respective force oriented in a respective plane. Respective primary data indicative of respective movement in a respective degree of freedom disposed within the respective plane for each test is generated based on the test data. Secondary data indicative of concomitant movement during a first test of the plurality of tests is generated based on the test data, the concomitant movement being in a secondary degree of freedom other than the respective degree of freedom disposed within the respective plane for the first test, the concomitant movement arising from the respective applied force. A joint condition is determined based on the primary data for each test and the secondary data.
