Fig. 7.
Joint capsule strain in ex vivo rabbit knees at (A) 6 locations, with principal strains and directions depicted as vectors at those locations (B, C). Detailed principal strains (P1 and P2) and principal axis angle (θ) for (D) 30–60°, (E) 60–90°, and (F) 30–90° flexions. There were significant effects of principal axis (P1 vs. P2) and location (proximal vs. central vs. distal patellar) on strain values. *P < 0.05, ***P < 0.0001.
