Effects of Knee Osteoarthritis on Hip and Ankle Gait Mechanics

open access: yesAdvances in Orthopedics, 2019
Introduction. Knee osteoarthritis (OA) can affect the hip and ankle joints, as these three joints operate as a kinetic/kinematic chain while walking. Purpose.

End-stage ankle osteoarthritis: exploring the precedent causes and time course of joint degeneration

open access: yesJournal of the Foot & Ankle
Introduction: End-stage ankle osteoarthritis (OA) is primarily post-traumatic, following injuries such as fractures, dislocations, and sprains. However, the timeline between initial injury and end-stage OA requiring surgical intervention remains poorly ...

Compensatory Function of the Subtalar Joint for Lower Extremity Malalignment

open access: yesAdvances in Orthopedics, 2019
It is important to evaluate the subtalar joint and hip-knee-ankle alignment to understand lower extremity alignment. In this review, we focused on the compensatory changes in the subtalar joint alignment for the deformity of the knee and ankle joint ...

Function of ankle ligaments for subtalar and talocrural joint stability during an inversion movement – an in vitro study

open access: yesJournal of Foot and Ankle Research, 2019
Background The lateral ankle ligament complex consisting of the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament (PTFL) is known to provide stability against ankle joint inversion.
