The foot and ankle outcome score (FAOS) has been
evaluated for many conditions of the foot and ankle. We evaluated
its construct validity in 136 patients with osteoarthritis of the
ankle, its content validity in 37 patients and its responsiveness
in 39. Data were collected prospectively from the registry of patients
at our institution. All
Introduction. The purpose of this study was to examine trends in patient characteristics and clinical outcomes that occur with age as a statistical variable when performing autologous osteochondral transplantation (AOT) for the treatment of osteochondral lesions of the talus (OLT). Methods. A retrospective cohort study for AOT procedures on 78 patients from 2006 to 2019. was conducted Clinical outcomes were evaluated via
Aims. The primary aim of this study was to address the hypothesis that fracture morphology might be more important than posterior malleolar fragment size in rotational type posterior malleolar ankle fractures (PMAFs). The secondary aim was to identify clinically important predictors of outcome for each respective PMAF-type, to challenge the current dogma that surgical decision-making should be based on fragment size. Methods. This observational prospective cohort study included 70 patients with operatively treated rotational type PMAFs, respectively: 23 Haraguchi Type I (large posterolateral-oblique), 22 Type II (two-part posterolateral and posteromedial), and 25 (avulsion-) Type III. There was no standardized protocol on how to address the PMAFs and CT-imaging was used to classify fracture morphology and quality of postoperative syndesmotic reduction. Quantitative 3D-CT (Q3DCT) was used to assess the quality of fracture reduction, respectively: the proportion of articular involvement; residual intra-articular: gap, step-off, and 3D-displacement; and residual gap and step-off at the fibular notch. These predictors were correlated with the Foot and Ankle Outcome Score (FAOS) at two-years follow-up. Results. Bivariate analyses revealed that fracture morphology (p = 0.039) as well as fragment size (p = 0.007) were significantly associated with the
Autologous osteochondral transplantation (AOT) is an effective treatment for large Osteochondral Lesions of the Talus (OLT), however little is reported on an athletic population, who are likely to place higher demands on the reconstruction. The aim is to report the outcomes of large OLT (>150mm. 2. ) within an athletic population. The study population was limited to professional or amateur athletes (Tegner score >6) with an OLT of size 150mm. 2. or greater. The surgical intervention was AOT with a donor site from the lateral femoral condyle. Clinical outcomes at a minimum of 24 months included Return to Sport, VAS and
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),
Aims. 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. Methods. 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). Results. All patients had ICRS grade IV cartilage lesions, except for one (ICRS grade III). The paired MOCART scores significantly improved from 42.5 (SD 1.53) to 63.5 (SD 22.60) (p = 0.025) in ten patients. Seven patients agreed to undergo second-look arthroscopy; 5 patients had grade I (normal) ICRS scores and two patients had grade II (nearly normal) ICRS scores. VAS, FFI, and all subscales of
Patients' perspective and experience is heavily modulated by their understanding of their pre-operative disability along with their overall coping strategy and life philosophy. Given that evidence-based practice is relying on patient-reported outcomes more and more, the orthopaedic community must be diligent in differentiating patients that may have the same objective outcome but vary widely on a patient-reported subjective basis. In clinical practice, patient selection is often a sensitive, experience-based decision process that screens for catastrophization, recognizing that certain patients will not benefit from a simple surgery. It is well appreciated that patient's catastrophization can affect their subjective outcome but there is little reported literature on this abstract concept. The study set out to determine if post-operative outcomes correlated with pre-operative catastrophization scales. This current study set out to look at a cohort of complex consecutive foot and ankle cases and describe the relationship between Patient Catastrophizing Score (PCS) and multiple functional outcomes that are used commonly in foot and ankle specifically (SF-12 & FAOS). The PCS has three subcategory rumination, helplessness and magnification. A single institution undertook recruitment in consecutive patients within three surgeon's practice. In the end, 46 patients were found to be eligible in the study with an average age of 54.72 ± 14.41 years-old, a majority female 30 / 46 (65.22%), a minority employed at the pre-operative visit 19/46 (41%) and with an average BMI of 26.2 ± 5.56. We found that the mental component of the SF12 had a statistically significant negative effect with the rumination score (r=−1.03) (p = 0.01) and the helplessness score (r=−1.05) (0.001). There was no statistically significant effect for the physical component of the SF-12. Looking at the
Introduction. Osteochondral lesions (OCLs) of the talus are a challenging and increasingly recognized problem in chronic ankle pain. Many novel techniques exist to attempt to treat this challenging entity. Difficulties associated with treating OCLs include lesion location, size, chronicity, and problems associated with potential graft harvest sites. Matrix associated stem cell transplantation (MAST) is one such treatment described for larger lesions >15mm2 or failed alternative therapies. This cohort study describes a medium-term review of the outcomes of talar lesions treated with MAST. Methods. A review of all patients treated with MAST by a single surgeon was conducted. Preoperative radiographs, MRIs and
Introduction. 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. Methods. 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. Results. 33 patients had a revision total ankle replacement between 2012 and 2016. 2 patients were deceased therefore 31 patients were included in the study. 4 patients declined participation for completing questionnaires. We received 15/27 (55.5%) completed questionnaires. The mean MOX-FQ average domain score for pain was (50.6 ± 26.9), walking/standing (62.4 ± 36.5) and social function was (43.7± 31.0). The mean
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
Aims. The aim of this prospective study was to evaluate the intermediate-term
outcomes after revision anatomical ankle ligament reconstruction
augmented with suture tape for a failed modified Broström procedure. Patients and Methods. A total of 30 patients with persistent instability of the ankle
after a Broström procedure underwent revision augmented with suture
tape. Of these, 24 patients who were followed up for more than two
years were included in the study. There were 13 men and 11 women.
Their mean age was 31.8 years (23 to 44). The mean follow-up was 38.5
months (24 to 56) The clinical outcome was assessed using the Foot
and Ankle Outcome Score (FAOS) and the Foot and Ankle Ability Measure
(FAAM) score. The stability of the ankle was assessed using stress
radiographs. Results. The mean

Purpose. To evaluate the clinical results of arthroscopic repair and open Ahlgren Larsson method in patients with chronic lateral ankle instability. Methods. We retrospectively evaluated 87 patients who were operated in our clinic between 2010 and 2018 with the diagnosis of chronic lateral ankle instability. 16 patients with osteochondral lesion, 5 patients with rheumatoid arthritis, 4 patients with ankle fractures of the same side, 2 patients with a history of active or previous malignancy were excluded. Preoperative and postoperative clinical evaluations were performed with AOFAS ankle-hindfoot score,
Aims. The aim of this study was to report the outcome following primary
fixation or a staged protocol for type C fractures of the tibial
plafond. Patients and Methods. We studied all patients who sustained a complex intra-articular
fracture (AO type C) of the distal tibia over an 11-year period.
The primary short-term outcome was infection. The primary long-term
outcome was the Foot and Ankle Outcome Score (FAOS). Results. There were 102 type C pilon fractures in 99 patients, whose mean
age was 42 years (16 to 86) and 77 were male. Primary open reduction
internal fixation (ORIF) was performed in 73 patients (71.6%), whilst
20 (19.6%) underwent primary external fixation with delayed ORIF.
There were 18 wound infections (17.6%). A total of nine (8.8%) were
deep and nine were superficial. Infection was associated with comorbidities
(p = 0.008), open fractures (p = 0.008) and primary external fixation
with delayed ORIF (p = 0.023). At a mean of six years (0.3 to 13;
n = 53) after the injury, the mean
Of those foot and ankle injuries requiring radiographs based on the Ottawa Foot and Ankle Rules only approximately 22% will have a fracture. This diagnostic cohort study examined if ultrasound could detect acute non-bony foot and ankle injuries. Ottawa Rules positive patients over 16 years were eligible. An ED member performed scans for injury of tendons and ligaments blind to radiograph findings. Patients without fracture were re-scanned at 2 weeks. The Foot and Ankle Outcome Score (FAOS), a validated, patient-reported outcome measure, was completed at baseline (based on pre-injury status), 2 and 6 weeks. 110 subjects participated. 99 did not have significant radiological fractures.
Growth factors are reported to play an important role in healing after acute Achilles tendon rupture (ATR). However, the association between growth factors and patient outcome has not been investigated previously. The aim of this retrospective study is to identify growth factors and related proteins which can be used as predictors of healing after ATR, ethical approval was obtained from the Regional Ethical Review Committees in Sweden and followed the guidelines of the Declaration of Helsinki. The study included 28 surgically treated patients (mean age 39.11 ± 8.38 yrs) with acute ATR. Healing was assessed by microdialysate two weeks after the surgery and performed on both injured and contralateral un-injured leg. The microdialysates were analyzed by proteomics based on mass spectrometry (MS) to detect growth factor expressions in ATR patients. One year after the surgery, healing outcomes were evaluated by patient-reported Achilles tendon Total Rupture Score (ATRS), Foot and Ankle Outcome Score (FAOS), and functional outcomes by heel-rise test. A total of 1549 proteins were detected in the microdialysates of which 20 growth factor/ related proteins were identified. 7 of these were significantly up-regulated (IGFBP2, Fold change (FC) = 4.07, P = 0.0036; IGFBP4, FC = 3.06, P = 0.009; CTGF, FC = 15.83, P = 0.003; HDGF, FC = 4.58, P = 0.003; GRB2, FC = 14.8, P = 0.0004; LTBP1, FC = 12.08, P = 0.0008; TGFBI, FC = 5.54, P = 0.001) and 1 down-regulated (IGFBP6) in the injured compared to the contralateral healthy side. Linear regression analysis revealed that TGFB1 was positively associated with improved ATRS (r = 0.585, P = 0.04) as well to ATRS subscales: less limitation in running (r = 0.72, P = 0.004), less jumping limitation (r = 0.764, P = 0.001) and less limitation caused by decreased tendon strength (r = 0.665, P = 0.012). Interestingly, all 7 up-regulated proteins were positively associated with less jumping limitations (IGFBP2, r = 0.667, P = 0.015; IGFBP4, r = 0.675, P = 0.013; CTGF, r = 0.668, P = 0.015; HDGF, r = 0.672, P = 0.014; GRB2, r = 0.665, P = 0.016; LTBP1, r = 0.663, P = 0,016). No associations were observed among any of the growth factor and
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
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. Method:. 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. Results:. There were 56 patients in Group A and 32 patients in Group B. There was no difference in Gender, side of operation and diagnosis reported between the 2 groups (P>0.05). Group A reported higher number of co-morbidities than Group B (1.54 vs. 1.00); p=0.032. There was no difference in AOFAS scores and
Purpose. Platelet Rich Plasma (PRP) has been shown to have positive effect in tendon regeneration in in-vitro and limited in-vivo animal studies. We aim to study PRP use in acute Achilles tendon rupture (ATR) regeneration in a purposely designed clinical trial. Methods. This is a prospective double-arm patient-blinded randomized controlled trial. ATR patients were randomized into PRP treatment or control groups. Non-operatively treated patients received PRP or control injection in clinic. In operatively treated patients, PRP gel was applied in the ruptured gap during percutaneous repair. Standard rehabilitation protocol was used and patients were followed up for 24 weeks. ATR, VISA-A and
After catastrophic failure of first generation, joint replacement as treatment option for ankle osteoarthritis is undergoing a revival with improved second generation designs. Short to mid-term results reportedly equal those of ankle arthrodesis in terms of complications and revision, but preserving joint motion and protecting neighbouring midfoot joints from overuse and consecutive osteoarthritis. However, most reports derive from developers centres excluding the learning curve. We present clinical results and subjective outcome of an initial patient series undergoing ankle replacement in an independent centre. From January 2004 to January 2008 a Hintegra. ®. prosthesis was implanted in 39 consecutive patients (41 ankles), average age 60.7 years (range 36.6–85.0), 13 males and 25 females. Repeated clinical follow up was done for an average of 2.2 years (range 0.5–4.3). All patients whose operation had been more than 0.7 years before were sent the
Researchers and clinicians measuring outcomes following total ankle replacement (TAR) are challenged by the wide range of outcome measures used in the literature without consensus as to which are valid, reliable, and responsive in this population. This review identifies region- or joint-specific outcome measures used for evaluating TAR outcomes and synthesises evidence for their measurement properties. A standard search strategy was conducted of electronic databases MEDLINE, EMBASE and CINAHL (to June 2015) to identify foot/ankle measures in use. A best evidence synthesis approach was taken to critically appraise measurement properties [COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN)] of identified measures. The review was restricted to English publications and excluded cross-cultural adaptations. Measurement properties collected from each article were coded for validity, reliability, responsiveness, or interpretability. Clinimetric evidence exists for identified measures tested in non-TAR populations, but were not the focus of this review. The search identified 14 studies to include in the best evidence synthesis with 32 articles providing clinimetric evidence for eight of the measures (one CBO, seven PRO), however only five measures were tested in a TAR population (Foot Function Index, Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale [AOFAS], Foot and Ankle Outcome Score, Self-Reported Foot and Ankle Score). Five studies provided clinimetric evidence in a TAR population and their methodological quality was assessed: (1) Validity—two good quality studies examining different measures provide moderate evidence supporting construct validity (FFI, AOS, AOFAS self-reported items; SEFAS); (2) Reliability—two good quality studies examining different measures provide moderate evidence supporting internal consistency and test-retest reliability (FFI, AOS, AOFAS self-reported items;
Background:. Achilles pathology is a serious and frequently occurring problem, especially in elite athletes. Recent research has suggested a role for the plantaris tendon in non-insertional achilles tendinopathy. We report on the outcomes after excision of the plantaris tendon in elite athletes. Aim:. To assess whether or not excising the plantaris tendon improves the symptoms of Achilles tendinopathy in elite athletes. Methods:. A group of 32 elite athletes who underwent plantaris tendon excision to treat medially located pain associated with non-insertional Achilles tendinopathy were investigated. Outcomes were assessed with pre and post-operative Visual Analogue Scores (VAS) for pain and the Foot and Ankle Outcome Score (FAOS) as well as time to return to sport and satisfaction scores. Results:. At a mean follow-up of 22.4 months (12–48), 29/32 (90%) of athletes were satisfied with the results. 30/32 athletes (94%) returned to sport at a mean of 10.3 weeks (5–27). The mean VAS score improved from 5.8 to 0.8 (p<0.01) and the mean
The aim of this study was to document the outcome following either early or delayed fixation for complex (AO-OTA type 43.C) fractures of the tibial plafond. From our trauma database we identified all patients who sustained a complex intra-articular fracture of the distal tibia over an 11-year period. Demographic data, fracture classification, management, complications and subsequent surgeries were recorded. The primary outcome measure was the development of early complications following surgery. The secondary outcome measure was the long-term patient reported outcome. There were 102 type C pilon fractures in 99 patients with a mean age of 42yrs (16–86) and 75.5% (n=77) were male. 73 (71.6%) patients underwent primary open reduction internal fixation (ORIF), with 20 (19.6%) undergoing primary external fixation with delayed ORIF. 34 complications were recorded in 28 (27.5%) patients. There were 18 (17.6%) infections, with a deep wound infection in 9 (8.8%) patients and a superficial wound infection in 9 (8.8%). Risk factors for developing infection were multiple co-morbidities (p=0.008), an open fracture (p=0.008), and primary external fixation with delayed ORIF (p=0.023). At a mean of 6 years (0.3–13; n=53) post injury the mean
This systematic review and meta-analysis was conducted to compare open reduction and internal fixation (ORIF) with primary arthrodesis (PA) in the treatment of Lisfranc injuries, regarding patient-reported outcome measures (PROMs), and risk of secondary surgery. The aim was to conclusively determine the best available treatment based on the most complete and recent evidence available. A systematic search was conducted in PubMed, Cochrane Controlled Register of Trials (CENTRAL), EMBASE, CINAHL, PEDro, and SPORTDiscus. Additionally, ongoing trial registers and reference lists of included articles were screened. Risk of bias (RoB) and level of evidence were assessed using the Cochrane risk of bias tools and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The random and fixed-effect models were used for the statistical analysis.Aims

Introduction. 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. Materials and methods. In prospective observational study 167 patients who had (AA) and minimum follow-up of 24 months were included.
Aim. 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. Method. 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. Results. There were 50 patients in group A and 31 in group B. There was no significant difference between age (Mean 64.5 (A) and Mean 61.3 (B), gender and side of operation between the groups (p>0.05). Group A had higher percentage of patients with OA and RA compared to Group B (p=0.027). Group B (1.16) reported higher co-morbidites than Group A (1.81); p=0.012. There was no difference in AOFAS scores,
Background. Lisfranc/midfoot injuries are complex injuries with a reported incidence of 1 in 55000 in literature and frequently overlooked. But, recently they are becoming more commonly diagnosed with advent of CT scan and examination under anaesthesias (EUA) for suspicion fractures. Here we present a case series results of a single surgeons experience over the last 6 years. Methods. Retrospective review of 68 patients treated by a single surgeon over the last 6 years. Injuries were diagnosed on plain Xrays, clinic examination. Any suspicious injury were further assessed by a CT scan, all injuries were confirmed by EUA and treated with open reduction and internal fixation within 4 weeks of injury. Post-operative immobilisation in full cast for 6 weeks then a removal boot with non-weight bearing for a total of 3months. They were followed up regularly initially at 3, 6 and 12months. At final review the following data was collected: clinical examination, plain x-ray looking for: late deformity, signs of OA in Lisfranc joint, Auto fusion rate, rate of metal work failure. The x-rays findings were correlated with: (1) type of fixation. (2) The following scores:
Introduction. Osteochondral lesions of the talus are common injuries following acute and chronic ankle sprains and fractures, the treatment strategies of which include both reparative and restorative techniques. Recently, restorative techniques (i.e., autologous osteochondral transplantation) have been become increasingly popular as a primary treatment strategy, in part due to the potential advantages of replacing “like with like” in terms of hyaline cartilage at the site of cartilage repair. The current study examines the functional results of autologous osteochondral transplantation of the talus in 72 patients. Methods. Between 2005 and 2009, 72 patients underwent autologous osteochondral transplantation under the care of the care of the senior author. The mean patient age at the time of surgery was 34.19 years (range, 16–85 years). The mean follow-up time was 28.02 months (range, 12–64 months). Patient-reported outcome measures were taken pre-operatively and at final-follow-up using the Foot and Ankle Outcome Score and Short-Form 12 general health questionnaire. Quantitative T2-mapping MRI was also performed on select patients at 1-year post-operatively. Results. The mean
There is no optimal treatment for osteochondral defects of the talus after failed primary surgical treatment. To treat these patients, a 15-mm diameter metal implant was developed for the medial talar dome. The present study was undertaken to evaluate the clinical effectiveness of the metal implantation technique for osteochondral lesions of the medial talar dome. This is a prospective case series. The inclusion criteria were the combination of a large OCD (ϕ >12 mm) of the medial talar dome, persistent complaints >1 year after treatment, and clinically relevant pain levels. The exclusion criteria were: age <18 years, OCD size >20 mm, ankle osteoarthritis grade 2 or 3, concomitant ankle pathology, and diabetes. The primary outcome measure was the Numeric Rating Scale pain (NRS) rest, walking, running, and stair climbing. Secondary outcome measures were: Foot Ankle Outcome Score (FAOS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score, and clinical and radiographic complications. The Wilcoxon signed ranks test was used to calculate p-values. Between October 2007 and March 2009 10 patients were included. The median follow-up was 2 years (range, 2–3 years). On preoperative CT scanning, the median lesion size was 15 (range, 12–20) × 11 (range, 8–14) mm. The NRS rest improved from a median of 3 (0–7) preoperatively to 0.5 (0–2) at final follow-up (p = 0.017), NRS walking from 6.5 (4–8) to 1 (0–4) (p = 0.005), NRS running from 9 (6–10) to 3 (0–10) (p = 0.024), and NRS stair climbing from 6 (4–8) to 1 (0–7) (p = 0.012). The
Introduction. 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. Methods. 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. Results. There were 102 ankles (77.2%) in group 1 and 30 ankles (22.7%) in group 2. There was no difference in age and BMI between groups (p > 0.05). AOFAS,
Total Ankle Arthroplasty (TAA) using the uncemented three component mobile design has shown encouraging results. There is limited literature on the optimal postoperative management. In our centre, TAA patients are mobilised 48 hours after surgery without a short leg plaster. The aim of this prospective audit was to measure the outcomes of these patients to ascertain if this is a safe and effective protocol. Patients who underwent primary TAA between March 2006 and March 2008 were invited to participate in the audit. Assessment included patient questionnaires which collected demographics, height and weight, Foot and Ankle Outcome Score (FAOS) and Short-Form-36 (SF-36). Clinical examination collected American Orthopaedic Foot and Ankle Score (AOFAS). Data was collected pre-operatively and at 3 and 6 months after surgery. A total of 48 ankle replacements in 46 patients were included. Primary diagnosis was osteoarthritis (25), post-traumatic osteoarthritis (9), and rheumatoid arthritis (12). Mean age was 63 years (range 33 to 83) and the majority were males (29, 60%). The average body mass index was 28 (SD 5.3). There were significant improvements to 3-months after surgery for AOFAS (mean 29 to 76, p<
0.0001),
Objectives. Osteochondral ankle defects (OCDs) mainly occur in a young, active population. In 63% of cases the defect is located on the medial talar dome. Arthroscopic debridement and microfracture is considered the primary treatment for defects up to 15 mm. To treat patients with a secondary OCD of the medial talar dome, a 15-mm diameter metal implant (HemiCAP ®) was developed. The set of 15 offset sizes was designed to correspond with the anatomy of various talar dome curvatures. Recently, two independent biomechanical cadaver studies were published, providing rationale for clinical use. The present study was undertaken to evaluate the clinical effectiveness and safety of the metal implantation technique for osteochondral lesions of the medial talar dome in a prospective study. Material and methods. Since October 2007, twenty patients have been treated with the implant. Four patients who did not meet the inclusion criteria and four patients who had less than one-year follow-up at the time of writing were left out of this analysis. Twelve patients are reported with one year (n=8) or two years (n=4) follow-up. All patients had had one or two earlier operations without success. On preoperative CT-scanning, the mean lesion size was 16 × 11 (range, 9–26 × 8–14) mm. Outcome measures were: Numeric Rating Scale pain (NRS) at rest and when walking, Foot Ankle Outcome Score (FAOS), American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score, and clinical and radiographic complications. Data are presented as median and range. The Wilcoxon signed ranks test was used to calculate p-values. Results. All patients recovered well from surgery. The NRS at rest improved from 3 (0–7) preoperatively, to 0.5 (0–4) after 1 year and 1 (0–1) after 2 years follow-up (p < 0.05). The NRS when walking was 6.5 (4–8) preoperatively, improving to 1.5 (0–5) at 1 year and 1 (0–2) at 2 years follow-up (p < 0.05). The five subscales of the
It is now well established that operative repair of Tendo Achilles (TA) ruptures reduces re-rupture rate compared with conservative treatment. Operative repair has been reported to be associated with significant morbidity in 11–29% of cases, in particular wound related complications. In 1977 Ma and Griffith described a percutaneous repair of the TA, however initial results showed a disappointingly high re-ruputre rate of approximately 10%. The senior author has modified the technique initially described in attempt to reduce the re-rupture rate. After marking out the course of the sural nerve, a 2 Ethibond suture is passed into the ruptured tendon end via a stab incision, and passed proximally as in a modified Kessler suture. The suture is then passed first proximally and then back distally in a criss-cross pattern via further stab incisions and brought out at the tendon stump. A second suture is passed into the distal stump in a similar fashion and the sutures tied with the foot in equinus. We recruited a cohort of patients who had undergone percutaneous repair in the last 5 years, and a cohort of age and sex matched controls who had undergone open repair. Both groups of patients were managed postoperatively in equinus cast for 8 weeks. Subjective outcome was measured using the Foot and Ankle Outcome Score (FAOS). Statistical analysis was performed using the Mann-Whitney U-test for non-parametric data. Fifteen patients, mean age of 41.3, underwent percutaneous repair. There were 9 men and 6 women. The median time from injury to repair was 2 days in the percutaneous group and 1 day in the open group. Post-operatively there was no statistically significant difference between the two groups in relation to time taken to return to work (12 (percutaneous) versus 10 (open) weeks). However the percutaneous group returned to sport sooner 6 (percutaneous) versus 12 (open) months; p=0.6). There were no re-ruptures in either group. There were two sural nerve injuries in the percutaneous group and none in the open group. There was no significant difference in mean
Bone demonstrates good healing capacity, with a variety of strategies being utilized to enhance this healing. One potential strategy that has been suggested is the use of stem cells to accelerate healing. The following databases were searched: MEDLINE, CENTRAL, EMBASE, Cochrane Database of Systematic Reviews, WHO-ICTRP, ClinicalTrials.gov, as well as reference checking of included studies. The inclusion criteria for the study were: population (any adults who have sustained a fracture, not including those with pre-existing bone defects); intervention (use of stem cells from any source in the fracture site by any mechanism); and control (fracture healing without the use of stem cells). Studies without a comparator were also included. The outcome was any reported outcomes. The study design was randomized controlled trials, non-randomized or observational studies, and case series.Aims
Methods
Hindfoot arthrodesis with retrograde intramedullary nailing has
been described as a surgical strategy to reconstruct deformities
of the ankle and hindfoot in patients with Charcot arthropathy.
This study presents case series of Charcot arthropathy patients
treated with two different retrograde intramedullary straight compression
nails in order to reconstruct the hindfoot and assess the results
over a mid-term follow-up. We performed a retrospective analysis of 18 consecutive patients
and 19 operated feet with Charcot arthropathy who underwent a hindfoot
arthrodesis using a retrograde intramedullary compression nail.
Patients were ten men and eight women with a mean age of 63.43 years
(38.5 to 79.8). We report the rate of limb salvage, complications requiring
additional surgery, and fusion rate in both groups. The mean duration
of follow-up was 46.36 months (37 to 70).Aims
Patients and Methods
Talonavicular and subtalar joint fusion through
a medial incision (modified triple arthrodesis) has become an increasingly
popular technique for treating symptomatic flatfoot deformity caused
by posterior tibial tendon dysfunction. The purpose of this study was to look at its clinical and radiological
mid- to long-term outcomes, including the rates of recurrent flatfoot
deformity, nonunion and avascular necrosis of the dome of the talus. A total of 84 patients (96 feet) with a symptomatic rigid flatfoot
deformity caused by posterior tibial tendon dysfunction were treated
using a modified triple arthrodesis. The mean age of the patients
was 66 years (35 to 85) and the mean follow-up was 4.7 years (1 to 8.3).
Both clinical and radiological outcomes were analysed retrospectively. In 86 of the 95 feet (90.5%) for which radiographs were available,
there was no loss of correction at final follow-up. In all, 14 feet
(14.7%) needed secondary surgery, six for nonunion, two for avascular
necrosis, five for progression of the flatfoot deformity and tibiotalar
arthritis and one because of symptomatic overcorrection. The mean
American Orthopaedic Foot and Ankle Society Hindfoot score (AOFAS
score) at final follow-up was 67 (between 16 and 100) and the mean
visual analogue score for pain 2.4 points (between 0 and 10). In conclusion, modified triple arthrodesis provides reliable
correction of deformity and a good clinical outcome at mid- to long-term
follow-up, with nonunion as the most frequent complication. Avascular
necrosis of the talus is a rare but serious complication of this
technique. Cite this article:
It has previously been suggested that among unstable
ankle fractures, the presence of a malleolar fracture is associated
with a worse outcome than a corresponding ligamentous injury. However,
previous studies have included heterogeneous groups of injury. The
purpose of this study was to determine whether any specific pattern of
bony and/or ligamentous injury among a series of supination-external
rotation type IV (SER IV) ankle fractures treated with anatomical
fixation was associated with a worse outcome. We analysed a prospective cohort of 108 SER IV ankle fractures
with a follow-up of one year. Pre-operative radiographs and MRIs
were undertaken to characterise precisely the pattern of injury.
Operative treatment included fixation of all malleolar fractures.
Post-operative CT was used to assess reduction. The primary and
secondary outcome measures were the Foot and Ankle Outcome Score
(FAOS) and the range of movement of the ankle. There were no clinically relevant differences between the four
possible SER IV fracture pattern groups with regard to the FAOS
or range of movement. In this population of strictly defined SER
IV ankle injuries, the presence of a malleolar fracture was not
associated with a significantly worse clinical outcome than its
ligamentous injury counterpart. Other factors inherent to the injury
and treatment may play a more important role in predicting outcome.
We have evaluated the clinical effectiveness
of a metal resurfacing inlay implant for osteochondral defects of
the medial talar dome after failed previous surgical treatment.
We prospectively studied 20 consecutive patients with a mean age
of 38 years (20 to 60), for a mean of three years (2 to 5) post-surgery.
There was statistically significant reduction of pain in each of
four situations (i.e., rest, walking, stair climbing and running;
p ≤ 0.01). The median American Orthopaedic Foot and Ankle Society
ankle-hindfoot score improved from 62 (interquartile range (IQR)
46 to 72) pre-operatively to 87 (IQR 75 to 95) at final follow-up
(p <
0.001). The Foot and Ankle Outcome Score improved on all
subscales (p ≤ 0.03). The mean Short-Form 36 physical component
scale improved from 36 (23 to 50) pre-operatively to 45 (29 to 55)
at final follow-up (p = 0.001); the mental component scale did not
change significantly. On radiographs, progressive degenerative changes
of the opposing tibial plafond were observed in two patients. One
patient required additional surgery for the osteochondral defect.
This study shows that a metal implant is a promising treatment for
osteochondral defects of the medial talar dome after failed previous
surgery. Cite this article:
