Hip osteoarthritis index results. (A, B) The scatter plot of area of path speed (F10) versus hip maximum angular velocity (F6) for 
individuals and affected leg of patients in three different severity grades (i.e., 
, 
, and 
) (A) pre- and (B) post-surgery. (C) compares the distribution of HOI in healthy individuals with affected legs in different severity grades pre- and post-surgery; the seven-group one-way ANOVA test with \(p^*< 0.0001\). (D, E) The scatter plot of area of path speed (F10) versus hip maximum angular velocity (F6) for the 
and 
legs and 
individuals (D) pre- and (E) post-surgery. (F) compares the distribution of HOI in 
individuals with 
and 
legs pre- and post-surgery; the five-group one-way ANOVA test with \(p^*< 0.0001\). Note that the regression line in all subfigures is identical, computed using the best features from healthy participants and the pre-surgery affected legs of patients.
