The purpose of this study was to assess the success rate and functional outcomes of bone grafting for periprosthetic bone cysts following total ankle arthroplasty (TAA). Additionally, we evaluated the rate of graft incorporation and identified associated predisposing factors using CT scan. We reviewed a total of 37 ankles (34 patients) that had undergone bone grafting for periprosthetic bone cysts. A CT scan was performed one year after bone grafting to check the status of graft incorporation. For accurate analysis of cyst volumes and their postoperative changes, 3D-reconstructed CT scan processed with 3D software was used. For functional outcomes, variables such as the Ankle Osteoarthritis Scale score and the visual analogue scale for pain were measured.Aims
Methods
Osteochondral lesions of the talus (OLT) are a common cause of disability and chronic ankle pain. Many operative treatment strategies have been introduced; however, they have their own disadvantages. Recently lesion repair using autologous cartilage chip has emerged therefore we investigated the efficacy of particulated autologous cartilage transplantation (PACT) in OLT. We retrospectively analyzed 32 consecutive symptomatic patients with OLT who underwent PACT with minimum one-year follow-up. Standard preoperative radiography and MRI were performed for all patients. Follow-up second-look arthroscopy or MRI was performed with patient consent approximately one-year postoperatively. Magnetic resonance Observation of Cartilage Repair Tissue (MOCART) score and International Cartilage Repair Society (ICRS) grades were used to evaluate the quality of the regenerated cartilage. Clinical outcomes were assessed using the pain visual analogue scale (VAS), Foot Function Index (FFI), and Foot Ankle Outcome Scale (FAOS).Aims
Methods
In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method. We conducted a retrospective analysis of prospectively collected data of all patients with infected Charcot foot deformity who underwent two-stage reconstruction with internal fixation between July 2011 and November 2019, with a minimum of 12 months’ follow-up.Aims
Methods
We report the medium-term outcomes of a consecutive series of 118 Zenith total ankle arthroplasties (TAAs) from a single, non-designer centre. Between December 2010 and May 2016, 118 consecutive Zenith prostheses were implanted in 114 patients. Demographic, clinical, and patient-reported outcome measures (PROMs) data were collected. The endpoint of the study was failure of the implant requiring revision of one or all of the components. Kaplan-Meier survival curves were generated with 95% confidence intervals (CIs) and the rate of failure calculated for each year.Aims
Methods
The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review.Objectives
Methods
The last decade has seen a considerable increase
in the use of in total ankle arthroplasty (TAA) to treat patients
with end-stage arthritis of the ankle. However, the longevity of
the implants is still far from that of total knee and hip arthroplasties. The aim of this review is to outline a diagnostic and treatment
algorithm for the painful TAA to be used when considering revision
surgery. Cite this article:
Neuropathic changes in the foot are common with
a prevalence of approximately 1%. The diagnosis of neuropathic arthropathy
is often delayed in diabetic patients with harmful consequences
including amputation. The appropriate diagnosis and treatment can
avoid an extensive programme of treatment with significant morbidity
for the patient, high costs and delayed surgery. The pathogenesis
of a Charcot foot involves repetitive micro-trauma in a foot with impaired
sensation and neurovascular changes caused by pathological innervation
of the blood vessels. In most cases, changes are due to a combination
of both pathophysiological factors. The Charcot foot is triggered
by a combination of mechanical, vascular and biological factors
which can lead to late diagnosis and incorrect treatment and eventually
to destruction of the foot. This review aims to raise awareness of the diagnosis of the Charcot
foot (diabetic neuropathic osteoarthropathy and the differential
diagnosis, erysipelas, peripheral arterial occlusive disease) and
describe the ways in which the diagnosis may be made. The clinical
diagnostic pathways based on different classifications are presented. Cite this article:
Osteochondral lesions (OCLs) occur in up to 70%
of sprains and fractures involving the ankle. Atraumatic aetiologies have
also been described. Techniques such as microfracture, and replacement
strategies such as autologous osteochondral transplantation, or
autologous chondrocyte implantation are the major forms of surgical
treatment. Current literature suggests that microfracture is indicated
for lesions up to 15 mm in diameter, with replacement strategies
indicated for larger or cystic lesions. Short- and medium-term results
have been reported, where concerns over potential deterioration
of fibrocartilage leads to a need for long-term evaluation. Biological augmentation may also be used in the treatment of
OCLs, as they potentially enhance the biological environment for
a natural healing response. Further research is required to establish
the critical size of defect, beyond which replacement strategies
should be used, as well as the most appropriate use of biological augmentation.

Pigmented villonodular synovitis (PVNS) is a
rare benign disease of the synovium of joints and tendon sheaths, which
may be locally aggressive. We present 18 patients with diffuse-type
PVNS of the foot and ankle followed for a mean of 5.1 years (2 to
11.8). There were seven men and 11 women, with a mean age of 42
years (18 to 73). A total of 13 patients underwent open or arthroscopic
synovectomy, without post-operative radiotherapy. One had surgery
at the referring unit before presentation with residual tibiotalar
PVNS. The four patients who were managed non-operatively remain
symptomatically controlled and under clinical and radiological surveillance.
At final follow-up the mean Musculoskeletal Tumour Society score
was 93.8% (95% confidence interval (CI) 85 to 100), the mean Toronto
Extremity Salvage Score was 92 (95% CI 82 to 100) and the mean American
Academy of Orthopaedic Surgeons foot and ankle score was 89 (95%
CI 79 to 100). The lesion in the patient with residual PVNS resolved radiologically
without further intervention six years after surgery. Targeted synovectomy
without adjuvant radiotherapy can result in excellent outcomes,
without recurrence. Asymptomatic patients can be successfully managed
non-operatively. This is the first series to report clinical outcome
scores for patients with diffuse-type PVNS of the foot and ankle. Cite this article:
