Surgical reconstruction of Charcot joint deformity is increasingly being offered to patients. In our centre a hybrid type fixation technique is utilised: internal and external fixation. This combined fixation has better wound management and earlier mobilisation in this deconditioned patient group. The aim of this study was to assess clinical, radiological and patient reported outcomes for all patients who underwent this hybrid technique. This is a prospective observational case series of all patients who underwent surgical reconstruction of Charcot foot deformity in a single centre between June 2017 and June 2023. Patient demographics, smoking status, diabetic control and BMI were recorded. Outcomes were determined from case notes and included clinical outcomes (complications, return to theatre, amputation and mortality) radiological outcomes and patient reported outcomes. The follow up period was 1–7 years post operatively.Introduction
Methods
Total Ankle Replacement (TAR) is an established treatment option for end-stage ankle arthritis. We analysed at minimum, 10-year patient-reported and clinical outcomes of 156 TARs from a single centre. We specifically compared outcomes between patients under 60 and over 60 at time of surgery. Data was collected retrospectively from our departmental patient database. It included all patients who underwent a TAR by a single surgeon between 2006 and 2010 and patients were divided into those under 60 and those over 60 at the time of surgery. Patient reported outcomes (PROMs), including WOMAC, SF-36 and patient satisfaction scores and complications were analysed preoperatively and at one, two, five and over 10 years postoperatively.Background
Methods
Total ankle arthroplasty (TAA) is an increasingly popular treatment option for patients with end-stage ankle arthritis. However, for most implant systems, failure rates of 10–20% have been reported within the first 10 years after primary TAA. Pain is the primary symptom that indicates failure of TAA but cause of it can be difficult to establish. All patients who underwent a primary TAA at our center were included in the study. The clinical outcomes were studied for patients requiring a further revision procedure following primary TAA. The reasons for revision surgery and outcomes of surgery were analyzed using appropriate inferential statistical tests.Introduction
Methods
Total ankle replacement as a valid treatment for end stage ankle arthritis, is gaining popularity and every year there is an increasing number of procedures. With revision rates as high as 21% at 5 years and 43% at 10 years there is a need for understanding and reporting the outcome of revision ankle replacement. Our aim was to study the patient reported outcomes following revision TAR with a minimum of 2 year follow up. All patients that underwent a revision total ankle replacement between 2012 and 2016 were included in the study. All patients received a post-operative questionnaire comprising of MOX-FQ score, EQ-5D (UK) and Foot and Ankle outcomes scores (FAOS) and patients satisfaction questionnaire with a minimum of 2 years follow up.Introduction
Methods
The effect of BMI on patient-reported outcomes following total ankle replacement (TAR) is uncertain and the change in BMI experienced by these patients in the 5 years following surgery has not been studied. We report a series of 106 patients with complete 5-year data on BMI and patient-reported outcome scores. Patients undergoing TAR between 2006 and 2009, took part in the hospital joint registry, which provides routine clinical audit of patient progress following total joint arthroplasty; therefore, ethics committee approval was not required for this study. Data on BMI, Foot and Ankle Score (FAOS) and SF-36 score were collected preoperatively and annually postoperatively. Patients who were obese (BMI >30) had lower FAOS scores pre-operatively and at 5 years, however this did not reach significance. Both obese (p = 0.0004) and non-obese (p < 0.0001) patients demonstrated a significant improvement in FAOS score from baseline to 5 years. This improvement was more marked for the non-obese patients. No significant differences were seen for SF36 scores between obese and non-obese patients either at baseline or 5 years. There was a trend for improved score in both groups. Mean pre-operative BMI was 28.49. Mean post-operative BMI was 28.33. The mean difference between pre- and post-operative BMI was −0.15, which was not statistically significant (p=0.55). There were no significant differences in revisions in the obese (2) and non-obese (1 and one awaited) groups at 5 years. This data supports use of TAR in the obese population, as significant increases in mean FAOS score were seen in this group at 5 years. Obesity did not have a significant influence on patients' overall health perceptions, measured by the SF36 and a trend for improvement was seen in both obese and non-obese patients. TAR cannot be relied upon to result in significant post-operative weight-loss without further interventions.
MRI is the preferred modality for the diagnosis of ankle joint pathology. Musculoskeletal radiologists aim to determine and report both chondral and/or osseous stability/instability of each lesion. The aim of this study was to specifically analyse the reliability of MRI reported findings in predicting the stability of OCL's in symptomatic patients. A single centre, single surgeon consecutive series of patients who had undergone an ankle arthroscopy procedure preceded by an MRI scan for symptomatic ankle pathology were included in this retrospective clinical study. All MRI scans were reported by a musculoskeletal radiologist. MRI reports and arthroscopic findings were extracted and analysed. Arthroscopy findings were taken as the gold standard.Background

Birmingham Metal-on-metal total hip resurfacing (BHR) is a bone-conserving option for patients with advanced articular damage. While the outcomes of Total Hip Replacement (THR) are well documented, there is a paucity of literature comparing the patient reported outcomes of BHR versus THR. This study aims to compare the patient reported outcomes for an impact on quality of life between patients who had a BHR vs. THR after correcting for selection bias. Patients who underwent a BHR or THR between July 2003 and December 2006 were included. Patient questionnaires included demographic details, co-morbidities, WOMAC, SF-36 Scores. In addition, a 4 point Likert scale was used to measure satisfaction post-operatively. The above data was collected pre-operatively and at 1, 2, 3 and 5 years post-operatively. Data was analysed with SPSS (version 19) software package. All analysis was adjusted for Age, gender, Co-morbidity and pre-operative score by using Multivariate regression analysis using a General Liner Model to rule out the effect of these predictors on outcomes between groups. 337 patients were included (205 for THR and 132 for BHR). BHR patients were younger than THR patients (49 vs. 67 years, p<0.01), were more likely to be male (68% vs. 42% of THR, p<0.01), reported fewer co-morbidities (1.06 vs. 1.59, p<0.01). BHR patients reported better WOMAC pain and function scores at 5 years (p<0.05). For SF-36 scores, BHR patients reported higher scores for all 8 domains at 1 year and 5 year follow up (p<0.05). BHR patients reported higher satisfaction than THR group for return to Activities of Daily Living and Recreational activities at 1 and 5 years (p<0.05) After correction for patient variability, BHR patients reported better improvement in pain and function and enjoyed a better quality of life in relation to return to ADL and recreational activities over to 5 years post-surgery.
Ankle arthritis is a leading cause of pain and disability. The effect of this condition on physical and mental health is similar to end stage hip arthritis. There is paucity of literature on PROMS following total ankle replacements (TAR) in comparison to total hip replacement (THR) or knee replacement (TKR). We aimed to study 5 year outcomes of TAR in comparison with TKR and THR. PROMS data from patients who underwent a primary THR, TKR or TAR from March 2003 to 2013 were collected from our hospital patient registry. They were divided into 3 groups based on the type of primary joint replacement. Patient demographics and patient reported outcomes (WOMAC, SF-36 scores and patient satisfaction scores at follow up) were compared at pre-op and 5 year follow up.Introduction:

There is paucity of literature on Gait analysis following Total Ankle Replacement (TAR). We aimed to study changes to gait after successful Mobility TAR. 20 patients who underwent a primary TAR, with a diagnosis of either OA or PTOA were recruited between October 2008 and March 2011. Gait analysis was carried out using the Helen Hayes marker system with VICON 3D opto-electric system pre-operatively, 3, 6 and 12 months post-operatively. Ankle kinematics and spatio-temporal parameters of gait were studied.Introduction:
Methods:
The aim of this study was to assess patients reported fitness to return to work and to driving after ankle replacement. Using Hospital Joint Registry, patients who underwent ankle replacement between 2006 and 2011 were invited to take part in the study. Questionnaires were sent to these patients. Participants were asked to report the nature and pattern of their work (full time or part time), time it took to return to work and subsequent nature of work. Participants were also asked about time to return to driving.Introduction:

Total Ankle Replacement is proving to be a viable option for younger patients with Post Traumatic Osteoarthritis of the Ankle. The aim of our study was to study the clinical and patient reported outcomes between patients of < 60 and > 60 years who underwent TAR. Patients who underwent a TAR between March 2006 and May 2009 were invited to take part in the hospital patient registry. They were divided into two groups based on Age (Group A-Age > 60 and Group B-Age < 60). Patient demographics, co-morbidities, Clinical (AOFAS) outcomes, patient reported outcomes (FAOS, SF-36, patient satisfaction) and complications were collected from patients pre-operatively and at 1, 2 and 3 years follow up. Comparisons were made between groups for all outcome measures.Introduction:

We aimed to study the effect of BMI on clinical and patient-reported outcomes in patients with TAR with a minimum follow-up of three years. Patients who underwent a TAR between March 2006 and May 2009 were invited to take part in the hospital patient registry. Patients were divided into two groups based on BMI (Group A – BMI <30 and Group B – BMI >30). Patient demographics, co-morbidities, clinical (AOFAS), patient reported outcomes (FAOS, SF-36, patient satisfaction) and complications were collected pre-operatively and at 1, 2 and 3 years and comparison made between groups.Aim

Postoperative pain following the 3 component ankle arthroplasty (AA) (Mobility™) is a recognised problem without any apparent cause. This study aimed to determine pattern of postoperative pain following Total Ankle Arthroplasty (TAA) and its management options. In prospective observational study 167 patients who had (AA) and minimum follow-up of 24 months were included. FAOS ankle score, patients' satisfaction, SF36 and diagrammatic mapping of postoperative pain among other parameters were collected preoperatively and postoperatively at 3 months, 6 months and the annually. 20 Patients (12%) had moderate to severe postoperative ankle pain following the ankle arthroplasty.Introduction
Materials and methods
A prospective cohort of patients undergoing total ankle arthroplasrty for arthritis following pilon fractures was included in the present study. This group of patients generally have poor soft tissue envelope and have had previous surgical interventions prior to the ankle arthroplasty, making the arthroplasty more difficult as well as prone to complications. The data collected included patient demographics, American Orthopaedic Foot and Ankle Score (AOFAS) and patient reported outcomes (FAOS, SF-36, patient satisfaction) The data was collected preoperatively and at 1 & 2 years postoperatively. The minimum follow-up period was 2 years post-operatively.Aim
Methods
Metatarsals stress fractures are common in athletes and dancers. Occasionally, such fractures could occur without trauma in peripheral neuropathic patients. There is no published series describing outcome of stress fractures in these patients. This study analyse these fractures, treatment and outcome. Retrospective study, January 2005 to December 2010. From a total of 324 patients with metatarsal fractures, 8 patients with peripheral neuropathy presented with second metatarsal non-traumatic fractures. Fractures were initially treated in cast for more than three months but failed to heal. Subsequently, this led to fractures of 3rd, 4th and 5th metatarsals. All patients remained clinically symptomatic due to fracture non-union. Operative treatment with bone graft and plating was used. Postoperatively below knee plaster and partial weight bearing for 12 weeks. Clinical and radiological surveillance continued until bone union.Background and objective

There is less literature reporting outcomes following total ankle replacement (TAR) in patients presenting with a coronal plane deformity preoperatively. This study compares clinical and patient reported outcomes at 1 year between TAR patients with and without coronal plane deformity. Patients from single centre prospective cohort (132) who underwent TAR between 2006 and 2010 were included. They were divided into 2 groups based on preoperative coronal plane deformity. Groups 1 and 2 had a coronal plane deformity of <10 and >10 respectively. Assessments included American Orthopaedic Foot and Ankle Score (AOFAS), Foot and Ankle Outcome Score (FAOS), SF-36 (Generic Health Measure) and complications recorded preoperatively and 3, 6 and 12 months postoperatively.Introduction
Methods
Cemented stems have shown 90–100% survivorship when coupled with polyethylene acetabular component. This study aims to compare cemented stem behaviour in combination with large metal on metal (MOM) vs. metal on poly (MOP) bearings. 100 patients were recruited into a single centre RCT (we required 40 in each group for power .90 to confirm stem subsidence of >0.5mm at 2 years; p< 0.05). Recruits were randomized to MOP (28mm) or MOM femoral heads with CPCS cemented femoral stem. Assessments included X-rays (AP pelvis), Harris Hip Scores, blood metal ion levels and patient questionnaires (WOMAC, SF-36, satisfaction questionnaire). Evaluations were done pre-operatively and 3, 12 and 24 months post operatively; blood metal ion measures at 1 year.Introduction
Patients and Methods
The recommended indications for total ankle replacement (TAR) are limited, leaving fusion as the only definitive alternative. As longer-term clinical results become more promising, should we be broadening our indications for TAR? Our single-centre series has 133 Mobility TARs with 3–48 months' follow-up. 16 patients were excluded who were part of a separate RCT. The series was divided into two groups. ‘Ideal’ patients had all of the following criteria: age >60y, BMI <30, varus/valgus talar tilt <10°, not diabetic, not Charcot, not post-traumatic. The ‘Not ideal’ group contained those who did not fit any single criteria. We compared complications and outcome scores between both groups.Background
Materials and Methods
There is no published series described change in bone mineral density (BMD) after ankle replacement. We present the results of a prospective study examining the effect of total ankle replacement (TAR) upon local bone mineral density (BMD). To design a method and assess the effect of TAR loading on local ankle bones, by analysing the BMD of different area around ankle before and after Mobility TAR.Introduction
Aim
Total ankle replacement (TAR) is increasingly offered as an alternative to ankle fusion for the management of severe ankle arthritis. As with all other types of joint arthroplasty, there are risks involved and complications that occur; these increase with case complexity. We present the complications and management from a single-centre series. Since 2006, we have performed 150 Mobility TARs with up to 4 years' follow-up. We have excluded 16 that are part of a separate RCT and 10 with less than 3 months' follow-up. 124 TARs were included in our study (117 patients). Three ankles (2.4%) had superficial wound infections treated successfully with antibiotics. One ankle (0.8%) required an arthroscopic washout and debridement but the implant was retained. 11 ankles (8.9%) had a Our figures are comparable with other series. Our complication rate has not changed significantly over time. Our results, at present, suggest that most complications (98%) with the Mobility TAR can be satisfactorily managed without having a detrimental effect on the implant. There have been proven and promising results with total ankle replacement. However, there is a significant complication rate that must be made clear to the patient via informed consent; the rate still remains higher than for hip and knee arthroplasty.
