Background. Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children, or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severe neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has excellent functional outcome. Objective. To assess the functional outcome of acute correction of neglected Talipes-quino-varus deformity in adults. Methods. This is cross sectional, hospital–based study that took place in Khartoum, Sudan. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed to all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopaedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one years after surgery. Results. The mean age was 19.9±4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7±7.1 (poor). This score improved to 80.7±13.7 (good to excellent), two years after surgery. However, this indicates significant change in the functional outcome after the operation (P value < 0.05). Excellent post-operative functional outcome was found among patients aged 18 – 23 years 18 (50%) P. value: 0.021. The majority of patients 36(90%) were fully satisfied with the operation, 2(5%) partially satisfied and 2(5%) were unsatisfied. Conclusion. Acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure

Aims. The primary aim of this study was to present the mid-term follow-up of a multicentre randomized controlled trial (RCT) which compared the functional outcome following routine removal (RR) to the outcome following on-demand removal (ODR) of the syndesmotic screw (SS). Methods. All patients included in the ‘ROutine vs on DEmand removal Of the syndesmotic screw’ (RODEO) trial received the Olerud-Molander Ankle Score (OMAS), American Orthopaedic Foot and Ankle Hindfoot Score (AOFAS), Foot and Ankle Outcome Score (FAOS), and EuroQol five-dimension questionnaire (EQ-5D). Out of the 152 patients, 109 (71.7%) completed the mid-term follow-up questionnaire and were included in this study (53 treated with RR and 56 with ODR). Median follow-up was 50 months (interquartile range 43.0 to 56.0) since the initial surgical treatment of the acute syndesmotic injury. The primary outcome of this study consisted of the OMAS scores of the two groups. Results. The median OMAS score was 85.0 for patients treated with RR, and 90.0 for patients treated with ODR (p = 0.384), indicating no significant difference between ODR and RR. The secondary outcome measures included the AOFAS (88.0 in the RR group and 90.0 for ODR; p = 0.722), FAOS (87.5 in the RR group and 92.9 for ODR; p = 0.399), and EQ-5D (0.87 in the RR group and 0.96 for ODR; p = 0.092). Conclusion. This study demonstrated no functional difference comparing ODR to RR in syndesmotic injuries at a four year follow-up period, which supports the results of the primary RODEO trial. ODR should be the standard practice after syndesmotic screw fixation. Cite this article: Bone Jt Open 2023;4(12):957–963

Aims. The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome. Methods. Adult patients (aged above 17 years) with traumatic syndesmotic injury, surgically treated within 14 days of trauma using one or two syndesmotic screws, were eligible (n = 490) for inclusion in this randomized controlled noninferiority trial. A total of 197 patients were randomized for either ODR (retaining the syndesmotic screw unless there were complaints warranting removal) or RR (screw removed at eight to 12 weeks after syndesmotic fixation), of whom 152 completed the study. The primary outcome was functional outcome at 12 months after screw placement, measured by the Olerud-Molander Ankle Score (OMAS). Results. There were 152 patients included in final analysis (RR = 73; ODR = 79). Of these, 59.2% were male (n = 90), and the mean age was 46.9 years (SD 14.6). Median OMAS at 12 months after syndesmotic fixation was 85 (interquartile range (IQR) 60 to 95) for RR and 80 (IQR 65 to 100) for ODR. The noninferiority test indicated that the observed effect size was significantly within the equivalent bounds of -10 and 10 scale points (p < 0.001) for both the intention-to-treat and per-protocol, meaning that ODR was not inferior to RR. There were significantly more complications in the RR group (12/73) than in the ODR group (1/79) (p = 0.007). Conclusion. ODR of the syndesmotic screw is not inferior to routine removal when it comes to functional outcome. Combined with the high complication rate of screw removal, this offers a strong argument to adopt on demand removal as standard practice of care after syndesmotic screw fixation.

Background. Patients who undergo either primary or revision total ankle replacement (TAR) expect improvements in pain, function and quality of life. The goal of this study was to measure the functional outcome improvements and the difference in patient-reported outcomes in patients undergoing primary total ankle replacements compared to revision TAR. Methods. A single-center prospective cohort study was undertaken between 2016 and 2022. All patients were followed up for a minimum of 6 months. Patients undertook the Manchester Oxford Foot Questionnaire (MoxFQ) and EQ-5D health quality questionnaires pre-operatively, at 6 months and yearly for life. The Mann Whitney test was undertaken for statistical analysis. Results. A total of 165 primary and 71 revision ankle replacements were performed between 2016 and 2022. The mean age was 71 years for primary replacements and 69 years for revisions. The INFINITY was utilized in the majority of primary total ankle replacements. Revision replacements were either the INBONE II or INVISION and they were most often revising the MOBILITY implant. The main indication for revision was aseptic loosening (83%). Other causes included infection, malalignment and insert wear. The overall MoxFQ improved by a mean of 46.5 for primaries and 40.2 for revisions. The EQ-5D score also showed overall improvements with the mean difference in mobility increasing by 1.6. Conclusion. Both primary and revision ankle replacements result in improved functional scores at 6 months, 1 year and 2 years. In this cohort with the implants used, both primary and revision ankle replacements demonstrate similar improvements in functional scores

Aims. The aim of this study was to evaluate the functional outcome in patients undergoing implant removal (IR) after fracture fixation below the level of the knee. Patients and Methods. All adult patients (18 to 75 years) undergoing IR after fracture fixation below the level of the knee between November 2014 and September 2016 were included as part of the WIFI (Wound Infections Following Implant Removal Below the Knee) trial, performed in 17 teaching hospitals and two university hospitals in The Netherlands. In this multicentre prospective cohort, the primary outcome was the difference in functional status before and after IR, measured by the Lower Extremity Functional Scale (LEFS), with a minimal clinically important difference of nine points. Results. A total of 179 patients were included with a median age of 50 years (interquartile range (IQR) 37 to 60), of whom 71 patients (39.7%) were male. With a median score of 60 before IR (IQR 45 to 72) and 66 after IR (IQR 51 to 76) on the LEFS, there was a statistically significant improvement in functional outcome (p < 0 .001). A total of 31 surgical site infections (17.3%) occurred. Conclusion. Although IR led to a statistically significant improvement of functional outcome, the minimal clinically important difference was not reached. In conclusion, this study shows that IR does not result in a clinically relevant improvement in functional outcome. These results, in combination with the high complication rate, highlight the importance of carefully reviewing the indication for IR. Cite this article: Bone Joint J 2019;101-B:447–453

Aims. This prospective cohort study aims to determine if the size of the tendon gap following acute rupture of the Achilles tendon shows an association with the functional outcome following non-operative treatment. . Patients and Methods. All patients presenting within two weeks of an acute unilateral rupture of the Achilles tendon between July 2012 and July 2015 were considered for the study. In total, 38 patients (nine female, 29 male, mean age 52 years; 29 to 78) completed the study. Dynamic ultrasound examination was performed to confirm the diagnosis and measure the gap between ruptured tendon ends. Outcome was assessed using dynamometric testing of plantarflexion and the Achilles tendon Total Rupture score (ATRS) six months after the completion of a rehabilitation programme. Results. Patients with a gap ≥ 10 mm with the ankle in the neutral position had significantly greater peak torque deficit than those with gaps < 10 mm (mean 23.3%; 7% to 52% vs 14.3%; 0% to 47%, p = 0.023). However, there was no difference in ATRS between the two groups (mean score 87.2; 74 to 100 vs 87.4; 68 to 97, p = 0.467). There was no significant correlation between gap size and torque deficit (τ = 0.103), suggesting a non-linear relationship. There was also no significant correlation between ATRS and peak torque deficit (τ = -0.305). . Conclusion . This is the first study to identify an association between tendon gap and functional outcome in acute rupture of the Achilles tendon. We have identified 10 mm as a gap size at which deficits in plantarflexion strength become significantly greater, however, the precise relationship between gap size and plantarflexion strength remains unclear. Large, multicentre studies will be needed to clarify this relationship and identify population subgroups in whom deficits in peak torque are reflected in patient-reported outcome measures. .

Background. Cheilectomy and arthrodesis are accepted procedures for symptomatic hallux rigidus. Although good functional outcomes have been reported, there is little data available on post-operative sporting ability for these patients. Aims. We investigated sporting ability and functional outcomes of two cohorts of patients, the first underwent dorsal cheilectomy and the second arthrodesis. Methods. Physical and sporting ability was assessed using the Foot & Ankle Ability Measure (FAAM) sports questionnaire. Functional outcomes were assessed using MOXFQ. Radiological assessment was done according to Hattrup and Johnson classification. (HJ). Results. Group A (cheilectomy) consisted of 38 feet (35 patients) with a mean age of 57.2 (31–84) and mean follow-up 21.4 months (6–43). 21.6% were HJ1, 43.2% HJ2 and 35.1% HJ3. Group B (arthrodesis) consisted of 49 feet (47 patients) with a mean age of 64.1 (41–81) and mean follow-up 18.5 months (5–41). 6.8% were HJ1, 40.9% HJ2 and 52.3% HJ3. Mean FAAM score for group A was 78.89% (28.1%–100%). Mean FAAM score for group B was 81.55% (28.1%-100%). Mean MOXFQ score for group A was 14.89/64 (0–41). Mean MOXFQ score for group B was 10.43/64 (0–50). Pain, walking/standing and social domains were 29.74 (0–70), 21.8 (0–96.4) and 17.76 (0–68.8) in group A respectively. In group B, it was 14.79 (0–75), 16.54 (0–78.6), and 17.76 (0–100) respectively. FAAM was higher for group B in comparison to group A, but not statistically significant (P=0.425). Mean MOXFQ score was better in group B compared to group A (P< 0.05). Pain domain in particular was better in group B (P< 0.05). Conclusion. Our results suggest that both cheilectomy and arthrodesis for hallux rigidus result in similar post-operative sporting ability. Arthrodesis is superior to cheilectomy in overall functional outcomes, particularly in the pain domain

Introduction. We performed a longitudinal outcome study involving the operative management of ankle fractures at two university teaching hospitals. This was a retrospective review of the quality of reduction and a prospective study into the functional outcome. Methods. All patients undergoing open reduction internal fixation of the ankle between November 2006 and November 2007 at one centre, and January to December 2009 at the other were included. Adequacy of reduction was assessed on the initial post-operative radiographs using Pettrone's criterion. The post-operative functional outcome was recorded using the Lower Extremity Functional Scale (LEFS), completed by postal or telephone follow-up at 64 months post injury (60–74 months). Results. There were 261 patients in the cohort, with a mean age of 47 years (17–91). Weber B fractures were sustained in 193 patients compared to 68 Weber C fractures. The medial malleolus was fractured in 43 cases, and a large posterior malleolar fragment (>20%) was found in 13 cases. Malreduction of the Weber B cohort was identified in 61 ankles (31%): Malreduction of the Weber C cohort was identified in 25 cases (37%): At time of follow-up 26 patients were not traceable or had died. Of the surviving 235 patients, 139 responded to the LEFS questionnaire (60%). The mean LEFS was 58 (out of 80) in the Weber B cohort and 61 in the Weber C cohort. Significantly lower LEFS were found in patients who had a malreduction in 2 or more criteria. Conclusion. Our study shows that there is high incidence of malreduction in the operative treatment of ankle fractures which leads to a significantly poorer functional outcome. We strongly recommend that adequate care and supervision are used in theatre together with post-operative independent review of intra-operative fluoroscopy images

Aims. This prospective cohort study aimed to determine if the size of the tendon gap following acute tendo Achillis rupture influences the functional outcome following non-operative treatment. Patients and methods. All patients presenting with acute unilateral tendo Achillis rupture were considered for the study. Dynamic ultrasound examination was performed to confirm the diagnosis and measure the gap between ruptured tendon ends. Outcome was assessed using dynamometric testing of plantarflexion and the Achilles tendon rupture score (ATRS) six months after the completion of a rehabilitation programme. Results. 38 patients (mean age 52 years, range 29–78 years) completed the study. Patients with a gap ≥10mm with the ankle in the neutral position had significantly greater peak torque deficit than those with gaps < 10mm (mean 23.3% vs 14.3%, P=0.023). However, there was no overall correlation between gap size and torque deficit (τ=0.103), suggesting a non-linear relationship. There was also weak correlation between ATRS and peak torque deficit (τ=−0.305), with no difference in ATRS between the two groups (mean score 87.2 vs 87.4, P=0.467). Conclusion. This is the first study to identify tendon gap size as a predictor of functional outcome in acute tendo Achillis rupture, although the precise relationship between gap size and plantarflexion strength remains unclear. Large, multi-centre studies will be needed to clarify this relationship and identify population subgroups in whom deficits in peak torque are reflected in patient-reported outcome measures

Open cheilectomy is an established surgical treatment for hallux rigidus. Cheilectomy is now being performed using minimally invasive (MIS) techniques. In this prospective study we report the outcome of minimally invasive cheilectomy comparing the results with a matched group who had cheilectomy using standard open procedure. Methods. Prospective study of 47 patients. 22 patients had MIS cheilectomy between March 2009 and September 2010. We compared the outcome with a matched group (25 patients) who had open cheilectomy. Functional outcome was assessed using the Manchester Oxford Foot and ankle questionnaire (MOXFQ). The MOXFQ is a validated questionnaire designed to be self-completed and used as an outcome measure for foot surgery. Patients' satisfaction and complications were recorded. Results. In the MIS group, the median follow up was 11 months (4–23). The median preoperative MOXFQ score was 34/64(23) and the median postoperative score was 19/64 (p = <0.02). In the open group the median follow up was 17 months (9–27). The median preoperative MOXFQ score was 35/64 and the median postoperative score was 7.5/64 (p = <0.0001). The metric score of the three domains of the MOXFQ showed statistical improvement in both groups. The improvement didn't reach statistical significance between the open and MIS groups. There were three failures in the open group (Fusion) compared to none in the MIS. Discussion. There was significant improvement in foot pain, function and social aspect in the MIS group comparable to the open group. In our analysis we didn't account for the learning curve involved in the MIS technique. The MIS procedure has the advantage of small incision and dissection and accordingly less swelling and quicker recovery. Conclusion. MIS cheilectomy is an effective alternative procedure with satisfactory functional outcome and high patient satisfaction. Results are comparable to the standard open cheilectomy with a lower apparent failure rate

Introduction. Symptomatic hallux valgus is a common clinical problem, current trends is towards minimally invasive procedures. The goal of this study is to evaluate the outcome of minimally invasive chevron ostoetomy, comparing it with a matched group who had open chevron osteotomy. Methods. Prospective study, 54 patients. MIS group 25 patients between October 2009 and November 2010. Open group 29 patients between Feb 2008 and October 2010. Inclusion criteria included, mild to moderate hallux valgus, no previous history of foot surgery, no history of inflammatory arthritis, or MTPJ arthritis. All the operations were performed by the senior author. Functional outcome and pain were evaluated using pre and post operative Manchester Oxford Foot and ankle questionnaire (MOXFQ). IMA and HVA, avascular necrosis and union were assessed. Complications and satisfaction were recorded. Results. The MIS group with mean age at operation of 55, showed significant improvement in all the domains of the MOXFQ. Walking (p <0.018), foot pain (p = <0.013), social interaction (p = <0.001). The mean HVA and IMA corrections were 11.8° and 6.3°, (p < 0.001). The open group with mean age at operation of 55 years showed significant improvement in all domains of the MOXFQ, walking (p = <0.0001), foot pain (p = <0.002), social interaction (p = <0.0001). The HVA and IMA corrections were 10.5 and 5.9 degrees respectively (p = <0.001). The improvement in MOXFQ and HVA and IMA corrections were not statistically significant between the MIS and open groups. Discussion and Conclusion. Our results showed that the MIS chevron osteotomy is an effective procedure with minimal complications and satisfactory functional outcome, comparable to the open standard chevron osteotomy. Larger sample size is required to confirm our findings


Introduction:. Inadequate reduction and fixation of ankle fractures leads to poor clinical outcomes although there are no well-established criteria to evaluate the quality of surgical fracture fixation of the ankle. The aim of our study was to validate Pettrone's criteria that can be used in the radiological assessment of the quality of ankle fracture fixation that predict the functional outcome. Methods:. A retrospective study was completed following the operative management of ankle fractures at a University teaching hospital between 1. st. January 2009 and 31. st. December 2009 were included in the study. Exclusion criteria were paediatric fractures, polytrauma, and fractures involving the tibial plafond. The fracture pattern was classified using the AO classification system. Three independent Foot and Ankle Consultants assessed the quality of surgical ankle fracture fixation using Pettrone's criteria. Approximately one year following the surgery, functional outcome was obtained using Lower Extremity Function Score (LEFS) and a modified American Orthopaedic Foot and Ankle Society score (AOFAS). The Mann-Whitney test was used for the LEFS and AOFAS functional scores. Logistic regression was performed upon age and gender with regards to functional outcome. Given that the Kappa coefficient is a pair wise statistic, the average pair wise agreement for each category of the Pettrone criteria was also determined. Results:. Sixty-one consecutive patients were included in the study with a mean age of 51 years (17–74 years) and a mean follow-up of 17.41 months (13–24 months). Using Pettrone's criterias, mean interobserver agreement was 90.0% (89.4–92.6%) with inadequate reduction in 20 cases (32.5%). Mean LEFS following inadequate reduction was 47.5 (1–79) and following satisfactory reduction was 55.9 (9–80) p=0.03. Conclusion:. Pettrone's criteria has high interobserver agreement for the quality of surgical fracture fixation of the ankle which correlates with functional outcome

We present a review of 97 consecutive BioPro. ®. metallic hemiarthroplasties performed in 80 patients for end-stage hallux rigidus, with a minimum of five years follow-up. The mean age of the cohort was 55 (22 to 74) years. No patient was lost to follow-up. There were 15 revisions performed, one for infection, two for osteolysis, and 12 for pain. The all cause survival rate at five years was 85.6% (95% confidence interval (CI) 83.5 to 87.9). Younger age was a significant predictor of revision (odds ratio 1.09, 95% CI 1.02 to 1.17, p=0.014) on excluding infection and adjusting for confounding variables (Cox regression). Significant improvements were demonstrated at 5 years in the Manchester Oxford foot questionnaire (13.9, 95% CI 10.5 to 17.2) and in the physical component of the short form 12 score (6.5, 95% CI 4.1 to 8.9). The overall satisfaction rate was 72%. The cost per quality-adjusted-life-year at 5 years, accounting for a 3% per year revision rate, was £3,714. The BioPro offers good short to mid-term functional outcome and is a cost effective intervention. The relative high revision rate is associated with younger age and the use of this implant may be limited to older patients

We randomised prospectively 60 consecutive patients who were undergoing internal fixation of similar fractures of the ankle into two groups, one of which was treated by immobilisation in a below-knee cast and the other by a functional brace with early movement. All were instructed to avoid weight-bearing on the affected side. They were seen at 6, 12, 26 and 52 weeks. The functional rating scale of Mazur et al was used to evaluate the patients at each follow-up and we recorded the time of return to work. After one year the patients completed the SF-36 questionnaire.

By then 55 patients remained in the study, 28 (mean age 45.5 years) in group 1 and 27 (mean age 39.5 years) in group 2. Those in group 2 had higher functional scores at each follow-up but only at six weeks was this difference significant (p = 0.02). They also had higher mean SF-36 scores, but this difference was significant only for two of the eight aspects investigated. For patients gainfully employed, not on workers’ compensation, the mean time from surgery to return to work was 53.3 days for group 2 and 106.5 days for group 1; this difference was significant (p = 0.01). No patient developed a problem with the wound or had loss of fixation.

Our findings support the use of a functional brace and early movement after surgery for fractures of the ankle.

Introduction:

The role of total ankle replacements remains unproven within orthopaedic literature. We present a prospective series of patients who underwent a SALTO TAR (Tornier) between October 2006 and January 2014.

Methods:

A cohort of 53 TAR (50 patients) were prospectively followed up and assessed clinically, radiologically and asked to complete FAOS, VAS and Modified AOFAS scores. Four patients had bilateral procedures. The mean age was 71 years old (range 42–92). The mean follow up was 55 months (range 6–92). Nineteen TARs (19 patients) have a follow up of more than 60 months.

Aims. 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. Methods. 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. Results. Out of 37 ankles, graft incorporation was successful in 30 cases. Among the remaining seven cases, four (10.8%) exhibited cyst re-progression, so secondary bone grafting was needed. After secondary bone grafting, no further progression has been noted, resulting in an overall 91.9% success rate (34 of 37) at a mean follow-up period of 47.5 months (24 to 120). The remaining three cases (8.1%) showed implant loosening, so tibiotalocalcaneal arthrodesis was performed. Functional outcomes were also improved after bone grafting in all variables at the latest follow-up (p < 0.05). The mean incorporation rate of the grafts according to the location of the cysts was 84.8% (55.2% to 96.1%) at the medial malleolus, 65.1% (27.6% to 97.1%) at the tibia, and 81.2% (42.8% to 98.7%) at the talus. Smoking was identified as a significant predisposing factor adversely affecting graft incorporation (p = 0.001). Conclusion. Bone grafting for periprosthetic bone cysts following primary TAA is a reliable procedure with a satisfactory success rate and functional outcomes. Regular follow-up, including CT scan, is important for the detection of cyst re-progression to prevent implant loosening after bone grafting. Cite this article: Bone Joint J 2024;106-B(5):475–481

Introduction. Ankle fractures represent approximately 10% of the fracture workload and are projected to increase due to ageing population. We present our 5 years outcome review post-surgical management of ankle fractures in a large UK Trauma unit. Methods. A total of 111 consecutive patients treated for an unstable ankle fracture were entered into a database and prospectively followed up. Baseline patient characteristics, complications, further intervention including additional surgery, functional status were recorded during five-year follow-up. Pre-injury and post-fixation functional outcome measures at 2-years were assessed using Olerud-Molander Ankle Scores (OMAS) and Lower Extremity Functional Scales (LEFS). A p value < 0.05 was considered significant. Results. The mean age was 46 with a male:female ratio of 1:1.1. The distribution of comorbidities was BMI >30 (25%), diabetes (5%), alcohol consumption >20U/week (15%) and smoking (26%). Higher BMI was predictive of worse post-op LEFS score (p = 0.02). Between pre-injury and post fixation functional scores at 2 years, there was a mean reduction of 26.8 (OMAS) and 20.5(LEFS). Using very strict radiological criteria, 31 (28%) had less than anatomical reduction of fracture fragments intra-operatively. This was, however, not predictive of patients' functional outcome in this cohort. Within 5-year period, 22 (20%) patients had removal of metalwork from their ankle, with majority 13 (59%) requiring syndesmotic screw removal. Further interventions included: joint injection (3), deltoid reconstruction (1), arthroscopic debridement (1), superficial sinus excision (2), and conversion to hindfoot nail due to failure of fixation (1). Reduction in OMAS was predictive of patients' ongoing symptoms (p=0.01). Conclusion. There is a significant reduction in functional outcome after ankle fracture fixation and patients should be counselled appropriately. Need for removal of metalwork is higher in patients who require syndesmosis stabilisation with screw(s)

Introduction. This is a multi-centre, prospective, observational study of 503 INFINITY fixed bearing total ankle arthroplasties. We report the minimum two-year results of this prosthesis which was introduced to the UK Market in 2014 and is now the most used ankle arthroplasty in the National Joint Registry of England and Wales. Methods. Patients were recruited from 11 centres in the United Kingdom between June 2016 and November 2019. Demographic, radiographic, and functional outcome data (Ankle Osteoarthritis Scale, Manchester Oxford Foot Ankle Questionnaire and Euroquol 5D-5L) were collected preoperatively, at 6 months, 1 year and 2 years and 5 years. The average age was 67.8 (range 23.9 to 88.5) and average BMI 29.3 (18.9 to 48.0). The COFAS grading system was used to stratify deformity. There were 261 (51.9%) COFAS Type 1, 122 (24.2%) COFAS Type 2, 31 (6.2%) COFAS 3 and 89 (17.7%) COFAS type 4. 38 patients (7.6%) presented with inflammatory arthritis. 99 (19.7%) implantations utilised patient specific instrumentation. Complications and reoperations were recorded as adverse events. Radiographs were assessed for lucencies, cysts and/or subsidence. Results. The mean follow up was 34.2 months (range 24–64). 15 patients have died, 8 withdrawn and 3 lost to follow up. 8 implants (1.6%) have been revised. According to the Glazebrook classification there were low grade complications in 6.6%, medium grade in 1.4% and high grade in 1.6%. There have been an additional 13 non revision re-operations (2.6%) at the latest follow up. There was a significant (p < 0.01) improvement across all functional outcome scores at a minimum of 2yr follow up. Discussion and conclusion. This large cohort has shown a low early revision rate and high functional outcomes with a low-profile fixed bearing prosthesis

Aims. Management of intra-articular calcaneal fractures remains a debated topic in orthopaedics, with operative fixation often held in reserve due to concerns regarding perioperative morbidity and potential complications. The purpose of this study was to identify the characteristics of patients who developed surgical complications to inform the future stratification of patients best suited to operative treatment for intra-articular calcaneal fractures and those in whom surgery was highly likely to produce an equivocal functional outcome with potential post-operative complications. Methods. All patients who underwent open reduction and internal fixation of calcaneal fractures utilizing the Sinus Tarsi approach between March 2014 and July 2018 were identified using theatre records. Patient imaging was used to assess pre- and post-operative fracture geometry with Computed Tomography (CT) used for pre-operative planning. Each patient's clinical presentation was established through retrospective analysis of medical records. Patients provided verbal consent to participation and patient reported outcome measures were recorded using the Maryland Foot Score. Results. Fifty-eight intra-articular calcaneal fractures (fifty-three patients including five bilateral, mean age = 46.91 years) were included. Forty-nine patients were injured as a result of a fall from a height (92.4%). Mean time from presentation to surgery was 3.23 days (range 0–21). Mean Maryland Foot score was found to be 77.6 (+/− 16.22) in forty-five patients. Five patients (9.4%) had wound complications; two superficial (3.7%) and three deep (5.6%). Conclusion. Intra-articular fractures of the calcaneus should be considered for surgical intervention in order to improve long-term functional outcomes. The Sinus Tarsi approach provides the potential to decrease the operative complication rate whilst maintaining adequate fixation, however, the decision to surgically manage these fractures should be carefully balanced against the risk of post-operative complications. This increased risk of complication associated with smoking may tip the balance against benefit from surgical management

Introduction. We report the functional outcome and survivorship of the Hintegra Total Ankle Replacement (TAR), in consecutive cases by multiple surgeons in a single UK institution. Between 2010–2014 the Hintegra TAR held 7.1% UK market share and surgeons should be aware of failure mechanisms. Methods. We conducted a retrospective review of prospectively collected data for 70 consecutive Hintegra TAR cases in a single institution between 2010–2014. Data collected included patient demographics, complications, reoperations, patient reported outcome measures (PROMS: AOS, MOX-FQ, pain VAS) and patient satisfaction. Results. The 70 patients (54 male/ 16 female) had an average age of 69 (range 48–84 years). Mean follow up was 76 months (range 60–04), 10 patients died during the follow up. Implant survivorship was 81.4% at most recent follow up. The commonest radiographic finding was periprosthetic cysts (n=28, 40%), size range (7–40mm), location of cysts: isolated talus (n=14), isolated tibia (n=6), mixed (n=8). 10 failed TARs were revised to Inbone TAR at a mean of 48 months (range 9–69). 3 Failed TARs were revised to arthrodesis (2 tibiotalar fusions, 1 hindfoot nail). 11 patients required reoperation with implant retention: 8 periprosthetic cyst debridement and grafting at a mean of 61 months (range 27–91), 1 lateral gutter debridement and 1 periprosthetic fracture ORIF. PROMS data was available for all patients. Overall patients showed marked improvement in functional outcome scores between pre-operative and final follow up questionnaires. Mean pre-op AOS: 62, MOX-FQ: 68 and pain VAS: 67.5 with mean final follow up scores of: AOS: 35, MOX-FQ: 36 and pain VAS: 30. Conclusion. Our experience demonstrates improved PROMS following ankle arthroplasty for patients with a mean follow up of 6.4 years. Implant survivorship is similar to other TAR studies. We have identified a high incidence of periprosthetic cysts and would recommend ongoing surveillance of these patients
