Answer

Werner et al, in a study of 10 patients with peroneal nerve injury resulting from multiligament instability, evaluated nonoperative treatment (n=5) against PTT transfer (n=5); there was also a control group (n=4) who did not have peroneal nerve injury. [28] Compared with the nonoperative group, the PTT-transfer group showed increased dorsiflexion at initial contact and at mid-late swing phase. Compared with the control group, the PTT-transfer group had similar gait patterns but tended to be more everted. Overall, gait analysis demonstrated significantly improved sagittal-plane ankle kinematics with PTT transfer, with some degree of subtle instability as the tradeoff.
