Data were analyzed according to pattern\/severity of tears, as confirmed surgically: peroneus brevis tears, reparable (PBR); peroneus brevis tears, irreparable (PBI); peroneus longus tears, irreparable (PLI); and concomitant irreparable tears of both tendons (PBI+PLI). The following parameters were analyzed: ankle sagittal motion, coronal motion, axial rotation, foot progression angle, sagittal power, sagittal moment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Twelve patients (18.5%) had the PBR pattern, 37 (56.9%) PBI, 10 (15.4%) PLI, and 6 (9.2%) PBI+PLI. Compared with the contralateral, nonpathologic extremities, limbs with peroneal tears had diminished ankle sagittal motion (mean 23.14 vs 24.30 degrees,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .012), ankle\/hindfoot axial rotation (6.26 vs 7.23 degrees,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .001), sagittal moment (1.16 vs 1.29 Nm\/kg,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001), and sagittal power (1.24 vs 1.47 W\/kg,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001). The most severe tear patterns had the greatest derangements in multiple parameters of gait (PBI+PLI &gt; PBI or PLI &gt; PBR). For example, all groups except PBR had loss of ankle sagittal moment and\/or power in the affected limb, and the greatest losses in moment and power were in the PBI+PLI group (1.22 vs 0.91 Nm\/kg,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .003 for moment; 0.73 vs 1.31 W\/kg,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .001 for power). The PBI+PLI group had a &gt;10-degree varus shift in coronal motion on the affected side (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .002).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This is the first study to demonstrate diminished biomechanical function in patients with peroneal tendon tears.
