CONTEXT Lateral ankle sprains can manifest into chronic mechanical joint laxity when not treated effectively. Joint laxity is often measured through the use of manual stress tests, stress radiography, and instrumented ankle arthrometers. PURPOSE To systematically review the literature to establish the influence of chronic ankle instability (CAI) on sagittal and frontal plane mechanical joint ...

Both invasive and non-invasive methods of ankle joint distraction for arthroscopic procedures have been described. Challenges prevail in achieving an adequate joint distraction for instrumentation inside the ankle joint especially in patients of large stature. We describe a technique, which safely offers effective joint distraction during ankle arthroscopy without the need for resorting to trac...

Purpose: Many research studies reported balance disorder as one of the most important consequences of Functional Ankle Instability. However, the Balance Recovery Strategy, which its deficiency can cause poor balance or secondary damages, has not been investigated in previous studies yet. The purpose of this article is to study the Balance Recovery Strategy in athletes with Functional Ankle Inst...

OBJECTIVE To investigate the difference of range of motion (ROM) of ankle according to pushing force, gender and knee position. METHODS One hundred and twenty-eight healthy adults (55 men, 73 women) between the ages of 20 and 51, were included in the study. One examiner measured the passive range of motion (PROM) of ankle by Dualer IQ Inclinometers and Commander Muscle Testing. ROM of ankle d...

BACKGROUND Ankle tape is widely used by athletes to prevent ankle sprain. Although there is growing evidence that ankle tape improve joint position sense, but yet it is not clear even if tape improve joint position sense after muscle fatigue, because fatigue impair joint position sense and raise the risk of ankle sprain. The aim of this study is to examine the effect of ankle tape on joint posi...

This paper provides an introduction to the biomechanics of the ankle, introducing the bony anatomy involved in motion of the foot and ankle. The complexity of the ankle anatomy has a significant influence on the biomechanical performance of the joint, and this paper discusses the motions of the ankle joint complex, and the joints at which it is proposed they occur. It provides insight into the ...

Objective : To study the correlation between ankle and knee cartilage morphology to test the hypothesis that knee joint cartilage loss in gonarthritis can be estimated retrospectively using quantitative MRI analysis of the knee and ankle and established regression equations; and to test the hypothesis that sex differences in joint surface area are larger in the knee than the ankle, which may ex...

BACKGROUND Arthrodesis is an effective and reliable treatment for end-stage ankle arthritis; however, many patients develop ipsilateral adjacent joint arthritis following surgery. The mechanism that drives adjacent joint arthritis remains uncertain. Cadaveric simulation permits direct investigation of the effects of both arthrodesis and movement strategy on adjacent joints during simulated walk...
