UNASSIGNED: Charcot arthropathy is a condition which is progressive, non-infectious, destructive and debilitating that commonly affect foot and ankle. This systematic review is to evaluate the occurrence of common outcomes associated with each intervention of Charcot neuroarthropathy in midfoot.
UNASSIGNED: A systematic review on literatures that were published from Jan 2010 to Jan 2020 were collected, reviewed and selected regarding the surgical treatment procedures of Charcot neuroarthropathy in midfoot.
UNASSIGNED: The initial search yielded 231 reports and after exclusion, nine out of the total studies were included in the outcome analysis for review. These were studies that included data concerning surgical reconstruction of Charcot arthropathy in the midfoot.
UNASSIGNED: It is suggested that soft tissue preparation and usage of combination of implants thus reduce the risk of infection as well as increase rigidity of construct, respectively. These factors will aid to improve outcome of midfoot Charcot arthropathy reconstruction.

BACKGROUND: Neuroarthropathy of the knee or Charcot knee, leading to chronic joint destruction, is a rare disease that is difficult to diagnose. The treatment of this condition is difficult and controversial.
METHODS: A 74-year-old Asian woman has had bilateral knee pain for 22 years and deformity for 10 years, which has been aggravating for 2 months. Physical examination showed bilateral knee varus deformity greater than 15°, and -20 to 90° range of motion. X-ray revealed bilateral varus deformity with massive free body hyperplasia. Combined with medical history as syringomyelia, the patient was diagnosed with bilateral Charcot knees and bilateral joint replacements were performed using Legacy Constrained Condylar Knee prostheses (LCCK; Zimmer, USA). The patient reported satisfactory treatment outcomes, pain relief, and improved range of motion in both knees, without postoperative complications or prosthesis loosening at 2 year after operation.
CONCLUSIONS: Total knee arthroplasty (TKA) may be considered a viable option for treating the Charcot knee. The use of constrained condylar prostheses can produce satisfactory results. Attention should be given to survival risks, complications, and other potential determining factors associated with TKA when devising a treatment strategy for the Charcot knee.

Charcot neuroarthropathy is a progressive arthropathy associated with neuropathy. In patients with diabetes, Charcot neuroarthropathy mostly affects the foot. In the present case, we encountered a rare presentation of Charcot neuroarthropathy of the knee and foot in a patient with latent autoimmune diabetes in adults. The patient, who may have developed the disease as a result of inappropriate physical exercise, was treated with total knee arthroplasty.

UNASSIGNED: Charcot neuroarthropathy of the ankle and the hindfoot is a complex clinical entity with a high risk of amputation. Charcot neuroarthropathy limb reconstruction has been proposed as a limb-salvaging procedure. However, there was a lack of information on the various available reconstruction methods, including the outcomes and complications. The present study aimed to evaluate the current literature and update on the trends regarding the surgical management of Charcot neuroarthropathy of the ankle and the hindfoot.
UNASSIGNED: All data published from January 2010 to January 2020 that investigated the methods of fixation and their respective outcomes for the surgical reconstruction in Charcot neuroarthropathy were analyzed. The union rate, amputation rates, and complications associated with these techniques were taken for statistical analysis.
UNASSIGNED: A total of 16 studies fit the inclusion criteria of this study, with four Level-III studies and 12 Level-IV studies were included. Ten studies utilized internal fixation only; five used a combination of internal fixation and circular external fixator, whereby there are three comparative studies between internal and external fixations, and two studies applied combined technique of internal and external fixations (hybrid fixation). One study describes the usage of circular external fixation only.
UNASSIGNED: The use of retrograde intramedullary nail as a treatment of choice in the reconstruction of Charcot neuroarthropathy ankle is recommended before an ulcer occurrence. Hydroxyapatite (HA)- coated screws are recommended for the locking mechanism to prevent migration in Charcot neuroarthropathy due to poor bony quality. Hybrid fixation is recommended for reconstruction in a condition of ulceration and more complex deformity as it provides a higher rate of limb salvage with less soft tissue irritation.

Total knee arthroplasty (TKA) is an effective procedure to treat many patients with end-stage knee arthropathy. However, the extension of TKA for patients with Charcot neuroarthropathy (CNA) is controversial, with relatively limited evidence defining optimal reconstruction techniques.This systematic review of relevant studies that were published from January 2000 to June 2020 aimed to define survivorship, complications, reoperation, and component revision rates of contemporary TKA performed for CNA.We identified 127 TKA performed for CNA in five studies that comprised ≥ 7 knees with ≥ 5 years of follow-up.Overall implant survivorship was 85.4%. The overall complication rate was 26.4%, with the most common complications including instability (24.0%), periprosthetic fracture (17.4%), infection (13.0%), ligament injury (10.9%) and aseptic loosening (10.9%).The aetiology of CNA and prosthesis type had no influence on clinical outcomes, whereas the effect of staging of disease and ataxia status was still inconclusive.Understanding the potential determinants, survivorship and risk of complications related to TKA performed in CNA may help surgeons to deal with patient expectations.

BACKGROUND: Charcot arthropathy (CN) can ultimately lead to limb loss despite appropriate treatment. Initial conservative treatment is the accepted treatment in case of a plantigrade foot. The aim of this retrospective study was to investigate the mid- to long-term clinical course of CN initially being treated conservatively, and to identify risk factors for reactivation and contralateral development of CN as well as common complications in CN.
METHODS: A total of 184 Charcot feet in 159 patients (median age 60.0 (interquartile range (IQR) 15.5) years, 49 (30.1%) women) were retrospectively analyzed by patient chart review. Rates of limb salvage, reactivation, contralateral development and common complications were recorded. Statistical analysis was performed to identify possible risk factors for limb loss, CN reactivation, contralateral CN development, and ulcer development.
RESULTS: Major amputation-free survival could be achieved in 92.9% feet after a median follow-up of 5.2 (IQR 4.25, range 2.2-11.25) years. CN recurrence occurred in 13.6%. 32.1% had bilateral CN involvement. Ulcers were present in 72.3%. 88.1% patients were ambulating in orthopaedic footwear without any further aids. Presence of Diabetes mellitus was associated with reactivation of CN, major amputation and ulcer recurrence. Smoking was associated with ulcer development and necessity of amputations.
CONCLUSIONS: With consistent conservative treatment of CN with orthopaedic footwear or orthoses, limb preservation can be achieved in 92.9% after a median follow-up of 5.2 years. Patients with diabetic CN are at an increased risk of developing complications and CN reactivation. To prevent ulcers and amputations, every effort should be made to make patients stop smoking.
METHODS: III, long-term retrospective cohort study.

BACKGROUND: Acute Charcot Neuroarthropathy (CN) is a destructive condition that is characterised by acute fractures, dislocations and joint destruction in the weight-bearing foot. The acute phase is often misdiagnosed and can rapidly lead to devastating health outcomes. Early diagnosis and management of CN is imperative to attenuate progression of this condition. Consequently, timely evidence-based assessment, diagnosis and management of acute CN is imperative.
OBJECTIVE: To identify the factors that impact the delivery of evidence-based care in assessment, diagnosis and management of people with acute CN.
METHODS: Systematic searches were conducted in four databases to identify studies in English that included factors that impact the delivery of evidence-based care in the assessment, diagnosis and management of people with acute CN. Articles and consensus/guideline documents were assessed for inclusion by the researchers and disagreements were resolved through consensus. Additionally backward citation searching was used to source other potentially relevant documents. Information relevant to the research question was extracted and thematic analyses were performed using qualitative synthesis.
RESULTS: Thirty-two articles and four additional consensus/guideline documents were included for data extraction and analyses. Information related to the research question was of expert opinion using the National Health and Medical Research Council (NHMRC) Levels of Evidence guidelines. Themes explaining practices that deviated from evidence-based care in assessment, diagnosis and management of acute CN centred around patient, health professional and health organisation/environmental. Delay to diagnosis is particularly influenced by the patient\'s knowledge of when to seek help, practitioner knowledge in knowing how to recognise and refer for appropriate immediate care, confusion in imaging and offloading and geographical and local health service resources to appropriately manage the condition.
CONCLUSIONS: Individual and health professional awareness and geographical barriers are key challenges to the effective delivery of evidence-based assessment, diagnosis and management of people with acute CN. Acute CN represents a medical emergency warranting the need for expedited assessment, diagnosis and management by appropriately trained health professionals in the appropriate.

UNASSIGNED: This systematic review evaluated the surgical outcomes of various ankle fracture treatment modalities in patients with Diabetes Mellitus as well as the methodological quality of the studies.
UNASSIGNED: For our review, four online databases were searched: PubMed, MEDLINE (Clarivate Analytics), CINAHL (Cumulative Index to Nursing and Allied Health) and Web of Science (Clarivate Analytics). The overall methodological quality of the studies was assessed with the Coleman Methodology Score. Data regarding diabetic ankle fractures were pooled into three outcomes groups for comparison: (1) the standard fixation cohort with management of diabetic ankle fractures using ORIF with small or mini fragment internal fixation techniques following AO principles, (2) the minimally invasive cohort with diabetic ankle fracture management utilizing percutaneous cannulated screws or intramedullary fixation, and (3) the combined construct cohort treated with a combination of ORIF and another construct (transarticular or external fixation).
UNASSIGNED: The search strategy identified 2228 potential studies from the four databases and 11 were included in the final review. Compared to the standard fixation cohort, the minimally invasive cohort had increased risk of hardware breakage or migration and the combined constructs cohort had increased risk of hardware breakage or migration, surgical site infection and nonunion. Limb salvage rates were similar for the standard fixation and minimally invasive cohorts; however, the combined constructs cohort had a significantly lower limb salvage rate compared to that of the standard fixation cohort. The mean Coleman Methodology Score indicated the quality of the studies in the review was poor and consistent with its limitations.
UNASSIGNED: The overall quality of published studies on operative treatment of diabetic ankle fractures is low. Treating diabetic ankle fractures operatively results in a high number of complications regardless of fixation method. However, limb salvage rates remain high overall at 97.9% at a mean follow-up of 21.7 months. To achieve improved limb salvage rates and decrease complications, it is critical is to follow basic AO principles, respect the soft tissue envelope or utilize minimally invasive techniques, and be wary that certain combined constructs may be associated with higher complication rates.
