Aim. Surgical options for management of a failed ankle arthroplasty are currently limited; typically conversion to fusion is recommended with only a few patients being considered for revision replacement surgery. This paper presents our experience of revision ankle replacements in a cohort of patients with failed primary replacements. Method. A total of 18 revision TAR in 17 patients were performed in patients with aseptic loosening. The technique was performed by a single surgeon (CSK) over a 4 year period between July 2014 and August 2018 using the Inbone

Objective. The purpose of this study was to determine the outcomes of revision ankle replacements, using the Invision implant and impaction allograft for massive talar dome defects following primary ankle replacement failure. Outcomes were assessed in terms of bone graft incorporation; improvement in patient reported outcome measures (PROMs); and survivorship of the revision ankle arthroplasty. Methods. A retrospective review of prospectively collected data identified eleven patients who had massive bone cysts and underwent revision of a failed primary

Introduction.
The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant. This is a single-centre retrospective review of patients who underwent primary total ankle arthroplasty (TAA) with a Vantage implant between November 2017 and February 2020, with a minimum of two years’ follow-up. Four surgeons contributed patients. The primary outcome was reoperation and revision rate of the Vantage implant at two years. Secondary outcomes included radiological alignment, peri-implant complications, and pre- and postoperative patient-reported outcomes.Aims

Background. Total ankle arthrpoplasty (TAA) was performed frequently for ankle deformity caused by rheumatoid arthritis (RA) and osteoarthritis (OA). TAA has some advantages over ankle arthrodesis in range of motion (ROM). However, loosening and sinking of implant have been reported with several prostheses, especially constrained designs. Recently, we have performed mobile bearing TAA and report short term results of this prosthesis followed average 3 years. Method. 20 total ankle prostheses were implanted in patients with RA (n=14) or OA (n=6) in 19 patients (5 male and 14 female, one bilateral), between 2005 and 2009. We used FINE

This combined with high resolution CT scan (SPECT-CT) with bone windows allows the linking of the information obtained in both investigations. The multiplanar anatomical information provided by CT is therefore linked with the functional, biological information of bone scintigraphy. The painful

Power production in the terminal stance phase is essential for propelling the body forward during walking and is generated primarily by ankle plantarflexion. Osteoarthritis (OA) of the ankle restricts joint range of motion and is expected to reduce power production at that ankle. This loss of power may be compensated for by unaffected joints on both the ipsilateral and contralateral limbs resulting in overloading of the asymptomatic joints.

Aim. This controlled study uses gait analysis to evaluate patients' pre- and post-ankle arthroplasty, post-ankle arthrodesis and compares the results with a healthy control group to assess whether these theoretical benefits are borne out in clinical practice. Method. Five patient groups (arthrodesis, arthroses, arthroplasty after 6 and 12 months and control) each consisting of 12 patients were analysed in our gait laboratory and the following parameters obtained at two different walking speeds: velocity, cadence, step length, stride length, the timing of toe off and the duration of stance phase. In addition, the ground reaction force during the whole gait cycle was recorded, as well as the range of movement of the knee and of the foot in relation to the tibia in walking and functional tests. Results. Subjects who had undergone arthrodesis were able to go faster with a longer step length on the affected side than their counterparts with an ankle prosthesis. However, this gain seemed to be at the expense of a symmetrical gait pattern and increased knee movement. Ankle prostheses also produced a stance phase and ground reaction force that was closer to the control group in duration and timing and also a more symmetrical timing of toe off. Discussion. Overall, our data supports the clinical observation that the gait pattern after
