Abstract

Background

Tibiotalar arthrodesis and total ankle replacement are current standards for treating end-stage ankle osteoarthritis. Our clinical understanding of biomechanical causes and risk factors for subtalar secondary osteoarthritis development following surgical treatment is limited. The objective of this retrospective study was to investigate subchondral bone morphometric differences of individuals treated with a tibiotalar arthrodesis or ankle arthroplasty that may influence subtalar joint measurements during overground walking; results were compared between surgical groups, their unaffected limb, and asymptomatic controls.

Methods

Previously collected kinematics were used to measure and compare subtalar joint space and congruence throughout the dynamic activity utilizing a correspondence-based joint measurement analysis. A morphometric analysis evaluated subchondral bone differences of the calcaneus subtalar joint between groups.

Findings

The affected subtalar joint of arthrodesis participants showed increased joint space distance in the medial facet during early stance that was related to kinematic differences compared to controls and their contralateral untreated limbs. Our morphometric analyses demonstrated subchondral bone asymmetries in both surgical groups compared to their contralateral untreated limbs.

Interpretation

Previously reported kinematic differences between treated and untreated limbs in arthrodesis participants may translate to the variations in joint space and morphology observed in this study. Our earlier findings within the arthroplasty group indicated no significant kinematic differences between treated and untreated limbs, and the current study showed minimal significant differences in joint space distances. Collectively, this suggests that arthroplasty joint space and subchondral bone shapes are not as strongly influenced by functional asymmetries as those in the arthrodesis group.

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
