Ankle arthritis can be a painful and debilitating condition for many patients. In contrast to hip and knee arthritis, most cases of cases of symptomatic ankle arthritis are post-traumatic in nature. The anatomy, biomechanics and cell biology of the ankle differ from the hip and knee, and this has been postulated to account for the differing rates of post-traumatic vs. primary osteoarthritis in ...

The ankle is a highly congruent joint with a surface area of 11-13 cm(2). Total ankle replacements have been attempted since the early 1970s and design has continually evolved as the early designs were a failure. This was because the stresses involved and the mutiaxial motion of the ankle has not been understood until recently. It has been shown that the talus slides as well as rolls during the...

Introduction: The most common cause of ankle osteoarthritis (OA) is posttraumatic, with around 80% of all cases, followed by primary and secondary ankle OA. Patients often present wit asymmetric involvement of the tibiotalar joint, resulting in valgus or varus deformity of the ankle and hindfoot. The etiology of asymmetric arthritic ankles can be divided into 2 main etiologic and morphologic gr...

INTRODUCTION Lateral ankle sprains belong to the most common injuries in sports and can result in chronic ankle instability (CAI) with residual symptoms like recurrent ankle sprains, ‘givingway’, pain or swelling [1]. In order to develop effective preventive and rehabilitative measures against lateral ankle sprains and CAI, it is important to get a detailed understanding of the related injury m...

Chronic ankle instability represents a typical sports injury which can mostly be seen in basketball, soccer, orienteering and other high risk sports. 20 to 40 % of the acute ankle sprains develop into chronic ankle instability. From a sports orthopaedic point of view, chronic ankle instability can be subdivided into a lateral, medial or a combination of both so called rotational ankle instabili...

BACKGROUND The efficacy of total ankle replacement compared with that of ankle fusion continues to be one of the most debated topics in foot and ankle surgery. The purpose of this study was to determine whether there are sufficient objective cumulative data in the literature to compare the two procedures. A systematic review of the literature addressing the intermediate and long-term outcomes o...

UNLABELLED Osteoarthritis of the ankle can occur secondary to alteration of the articular surfaces, such as in the posttraumatic setting, or because of gradual degeneration as a result of biomechanical dysfunction. Although primary inflammatory ankle arthritis rarely occurs, the majority of cases of ankle osteoarthritis occur after bony trauma, ligamentous injury, congenital deformity, or previ...

Residual hip impairments, such as decreased hip muscle moment and power during walking, have been reported in patients with total hip arthroplasty (THA). Meanwhile, greater ankle power has also been reported in these patients. We investigated the interaction between hip and ankle joints during walking to determine the effects of different ankle pushoff instructions on hip biomechanics in patien...

OBJECTIVE: To outline rehabilitation concepts that are applicable to acute and chronic injury of the ankle, to provide evidence for current techniques used in the rehabilitation of the ankle, and to describe a functional rehabilitation program that progresses from basic to advanced, while taking into consideration empirical data from the literature and clinical practice. BACKGROUND: Important c...

Isolated syndesmosis injuries often go unrecognized and are diagnosed as lateral ankle sprains; however, they are more disabling than lateral ankle sprains. The reported incidence of isolated syndesmosis injuries in acute ankle sprains ranges between 1% and 16%. When ankle disability lasts for more than 2 months after an ankle sprain, the incidence increases to 23.6%. Diagnostic workup may incl...
