RESUMO

PURPOSE: Current options for treating an Achilles tendon rupture (ATR) include conservative and surgical approaches. Endoscopic flexor hallucis longus (FHL) transfer has been recently proposed to treat acute ruptures, but its cost-effectiveness potential remains to be evaluated. Therefore, the objective of this study was to perform an early cost-effectiveness analysis of endoscopic FHL transfer for acute ATRs, comparing the costs and benefits of current treatments from a societal perspective. METHODS: A conceptual model was created, with a decision tree, to outline the main health events during the treatment of an acute ATR. The model was parameterized using secondary data. A systematic review of the literature was conducted to gather information on the outcomes of current treatments. Data related to outcomes of endoscopic FHL transfers in acute Achilles ruptures was obtained from a single prospective study. Analysis was limited to the two first years. The incremental cost-effectiveness ratio was the main outcome used to determine the preferred strategy. A willingness-to-pay threshold of $100,000 per quality-adjusted life-year was used. Sensitivity analyses were performed to determine whether changes in input parameters would cause significant deviation from the reference case results. Specifically, a probability sensitivity analysis was conducted using Monte Carlo simulations, and a one-way sensitivity analysis was conducted by sequentially varying each model parameter within a given range. RESULTS: For the reference case, incremental cost-effectiveness ratios exceeded the willingness-to-pay threshold for all the surgical approaches. Overall, primary treatment was the main cost driver. Conservative treatment showed the highest direct costs related to the treatment of complications. In the probabilistic sensitivity analysis, at a willingness-to-pay threshold of $100,000, open surgery was cost-effective in 50.9%, minimally invasive surgery in 55.8%, and endoscopic FHL transfer in 72% of the iterations. The model was most sensitive to parameters related to treatment utilities, followed by the costs of primary treatments. CONCLUSION: Surgical treatments have a moderate likelihood of being cost-effective at a willingness-to-pay threshold of $100,000, with endoscopic FHL transfer showing the highest likelihood. Following injury, interventions to improve health-related quality of life may be better suited for improved cost-effectiveness. LEVEL OF EVIDENCE: Level III.

RESUMO

BACKGROUND: The Portuguese Pharmaceutical Society (PPS) implemented a system of Continuous Professional Development (CPD) for pharmacists in 2004. This system has evolved throughout the years, and currently all active pharmacists in Portugal are required to participate in the CPD program. Each CPD cycle takes 5 years. In each cycle, pharmacists must collect 15 CPD points, through participation in educational activities. The PPS accreditation process is managed via an online platform, where education/training providers, as well as pharmacists themselves, can submit educational activities for accreditation. Pharmacists may access their CPD status and assess their development at any point. The objective of this study was to analyze and review the educational activities submitted by providers over a 11-year period (2009-2019). METHODS: Data from activities were retrieved from the PPS CPD online platform. All educational activities were labeled according to the area of pharmaceutical professional focus, type of promoter, and activity type. RESULTS: During the study 3685 activities were analyzed. Over the last decade, submitted activities for accreditation increased in 52.6%. A significantly high proportion (98.9%) of these activities has been accredited. Promoters of activities were mostly pharmacies sectoral associations (29.6%), consultancy/training companies (19.6%), the PPS (18.5%), pharmaceutical industry (17.7%) and wholesalers' consortia (9.0%). Academia represented only 2.3% of the total amount of educational activities. The most frequent topics were related to "pharmacology & pharmacotherapy" (9.9%), followed by "counselling" (9.8%) and "management & administration" (7.2%). The most accredited type of activities was face-to-face (68.9%) and e-learning trainings (13.1%). CONCLUSIONS: This study shows increasing interest in submitting CPD activities for accreditation between 2009 and 2019, but it also demonstrates that Academia could play a more interventive role in the lifelong learning education of Portuguese pharmacists.

RESUMO

PURPOSE: Surgeons management of osteochondral lesions of the talus (OLT) may be different to the published guidelines because not all treatment recommendations are feasible in every country. This study aimed to assess how OLT are managed worldwide by foot and ankle surgeons. METHODS: A web-based survey was distributed to the members of 21 local and international scientific societies focused on foot and ankle or sports medicine surgery. Answers with a prevalence greater than 75% of respondents were considered a "main tendency", whereas where prevalence exceeded 50% of respondents they were considered a "tendency". RESULTS: A total of 1804 surgeons from 79 different countries returned the survey. The responses to 19 of 28 questions (68%) regarding management and treatment of OLT achieved a main tendency (> 75%) or a tendency (> 50%). Symptoms reported to be most suspicious for OLT were pain on weight-bearing (WB) and after activity (83%), deep localization of the pain (62%), and any history of trauma (55%). 89% of surgeons routinely obtain an MRI, 72% routinely get WB radiographs, and 50% perform a CT scan. When treated surgically, OLTs are managed in isolation by only 7% of surgeons, and combined with ligament repair or reconstruction by 79%; 67% report simultaneous excision of soft-tissue or bony impingements (64%). For lesions less than 10-15 mm in diameter, bone marrow stimulation (BMS) represents the first choice of treatment for 78% of surgeons (main tendency). No other treatment was recorded as a tendency. For lesions greater than 15 mm in diameter no tendencies were recorded. The BMS represented the most preferred treatment being the first choice of treatment for 41% of surgeons. OLT depth had little influence on treatment choice: 71% of surgeons treating small lesions and 69% treating large lesions would choose the same treatment regardless of whether the lesion had a depth lesser or greater than 5 mm. CONCLUSION: The management of OLT by foot and ankle surgeons from around the world remains extremely varied. The main clinical relevance of this study is that it provides updated information with regard to the management of OLT internationally, which could be used by surgeons worldwide in their decision-making and to inform the patient about available surgical options. LEVEL OF EVIDENCE: Level IV.

RESUMO

Acute Achilles tendon rupture can be treated either surgically or nonsurgically. The flexor hallucis longus (FHL) has been used successfully in patients with large chronic Achilles tendon defects. The aim of this study was to describe the clinical outcomes of isolated endoscopic FHL transfer in patients with acute Achilles tendon ruptures at a minimum follow-up of 18 months. Fifty-six male patients with an average age of 36.3 years who underwent endoscopic FHL transfer as a treatment for acute Achilles tendon ruptures were included. Follow-up was for a mean (± standard deviation) of 27.5 ± 7.29 months. At 18 months postoperatively, the Achilles tendon total rupture score mean was 95 ± 4.26, and the American Orthopaedic Foot and Ankle Society score was a mean of 96.4 ± 4.31. The median value for FHL tendon dynamometry on the surgical side was 95.72 (range 70.1 to 142), and 100.7 (range 68 to 161) for the nonoperated side. Mean ankle plantarflexion strength at 18 months was 19.19 ± 2.55 kg • m compared with the uninjured side of 19.27 ± 2.16 kg • m. Relative Achilles tendon resting angle showed a mean of -0.25° ± 2.43°. Magnetic resonance imaging performed at a minimum of 18 months postoperatively showed a homogeneous continuous Achilles tendon signal for 43 patients and heterogeneous signal intensity in 13 patients (23.21%). No patients reported any great toe complaints or symptomatic deficits of flexion strength. No neurovascular or skin complications were encountered. The current study demonstrated satisfactory and comparable results with minimal complications when using the endoscopic FHL tendon transfer in surgical management of acute Achilles tendon ruptures, compared with the currently used methods.

RESUMO

PURPOSE: The purpose of this review is to systematically analyse current literature on the use of allografts in the surgical treatment of foot and ankle disorders in adult patients. Based on this study, we propose evidence-based recommendations. METHODS: The database for PubMed was searched for all published articles. No timeframe restrictions were applied. Clinical studies eligible for inclusion met the following criteria: performed on patients over 18 years old; subject to surgical treatment of foot and ankle disorders; with report on the outcome of the use of allografts; with a report and assessment of pain and function, or equivalent; minimum follow-up of 1 year was required. Two reviewers independently screened and selected studies for full-text analysis from title and abstract. 107 studies were included from 1113 records. Studies were grouped according to surgical indications into ten categories: musculoskeletal tumours (n = 16), chronic ankle instability (n = 15), ankle arthritis (n = 14), osteochondral lesions of the talus (n = 12), Achilles tendon defects (n = 11), other tendon defects (n = 9), fusions (n = 9), fractures (n = 8), hallux rigidus (n = 3) and other indications (n = 10). RESULTS: Most studies displayed evidence level of IV (n = 57) and V (n = 39). There was one level I, one level II and nine level III studies. Most studies reported allografting as a good option (n = 99; 92.5%). Overall complication rate was 17% (n = 202). CONCLUSIONS: Fair evidence (Grade B) was found in favour of the use of allografts in lateral ankle ligament reconstruction or treatment of intra-articular calcaneal fracture. Fair evidence (Grade B) was found against the use of allogeneic MSCs in tibiotalar fusions. LEVEL OF EVIDENCE: V.

RESUMO

Ankle sprain is amongst the most frequent musculoskeletal injuries, particularly during sports activities. Chronic ankle instability (CAI) resulting from an ankle sprain might have severe long-lasting consequences on the ankle joint. Despite the fact that most patients will respond favourably to appropriate conservative treatment, around 20% will develop symptomatic CAI with sense of giving away and recurrent sprains leading to functional impairment. "Classical" surgical repair by Brostrom-like surgery in one of its many modifications has achieved good results over the years. Recently, major advances in surgical techniques have enabled arthroscopic repair of ankle instability with favourable outcome while also enabling the treatment of other concomitant lesions: loose bodies, osteochondral defects (OCDs) or ankle impingement. Moreover, when the tissue remnant does not permit a repair technique, anatomic reconstruction by means of using a free graft has been developed. In many cases, OCDs occur as a consequence of CAI. However, traumatic and non-traumatic aetiologies have been described. There is no evidence favouring any surgical treatment over another concerning OCDs. Considering lower cost and limited aggression, microfracture is still the most frequent surgical approach. Herein, the authors describe their algorithm in the treatment of these conditions. Similarly, anterior or posterior impingement might be linked with CAI. These are clinical syndromes based on clinical diagnosis which are currently managed arthroscopically upon failure of conservative treatment.

RESUMO

PURPOSE: The purpose of this study is to propose recommendations for the treatment of patients with chronic lateral ankle instability (CAI) based on expert opinions. METHODS: A questionnaire was sent to 32 orthopaedic surgeons with clinical and scientific experience in the treatment of CAI. The questions were related to preoperative imaging, indications and timing of surgery, technical choices, and the influence of patient-related aspects. RESULTS: Thirty of the 32 invited surgeons (94%) responded. Consensus was found on several aspects of treatment. Preoperative MRI was routinely recommended. Surgery was considered in patients with functional ankle instability after 3-6 months of non-surgical treatment. Ligament repair is still the treatment of choice in patients with mechanical instability; however, in patients with generalized laxity or poor ligament quality, lateral ligament reconstruction (with grafting) of both the ATFL and CFL should be considered. CONCLUSIONS: Most surgeons request an MRI during the preoperative planning. There is a trend towards earlier surgical treatment (after failure of non-surgical treatment) in patients with mechanical ligament laxity (compared with functional instability) and in high-level athletes. This study proposes an assessment and a treatment algorithm that may be used as a recommendation in the treatment of patients with CAI. LEVEL OF EVIDENCE: V.

RESUMO

Recent studies show that skipping breakfast is associated with an increased risk of obesity, diabetes and cardiovascular diseases. In this context, this study evaluated 400 patients from the Brazilian health service who had their nutritional status defined based on the body mass index and were classified as physically active or insufficient active. The energy intake and macronutrients was also assessed by a 24-hour dietary recall where the association of overweight/obesity with the investigated variables was evaluated using chi-square, Student's t test and multivariate analysis (p < 0.05). The main results showed that more than half of the studied population have the habit of omitting breakfast (55.8%), and among those, 81.2% were overweight/obese (p < 0.0001). Almost three-fourths of these individuals consumed no more than 4 meals a day (73.0%), and regarding this meal frequency/day, 78.8% of the individuals who reported having 4 meals or less a day were overweight/obese compared with 57.8% who reported as having 5-6 meals/day (p < 0.0001). The individuals who reported to omit breakfast had a higher chance of being overweight compared with those who had this habit (OR 2.20; 95% CI 1.40-3.60) and the chance of the physically insufficient active individuals to be overweight/obese was 2.9 times higher when compared to the active individuals (p < 0.0001). Our findings suggest that regular breakfast consumption may decrease overweight and obesity risk.

RESUMO

Ankle ligament injuries are one of the most frequent lesions identified in professional soccer players. In most cases, the ligaments involved are the anterior talofibular ligament and the calcaneal fibular ligament. In the present report, we describe a professional soccer player who sustained an ankle sprain that did not respond to initial therapy. The findings from radiographic and magnetic resonance images were inconclusive. Ultimately, rupture of the posterior, transverse ligament with avulsion of the tibial labrum was identified as the cause of his ongoing ankle pain. Confirmation of the pathologic findings and successful treatment were performed arthroscopically.

RESUMO

INTRODUCTION: Recurrent subluxation of the peroneal tendons over the lateral malleolus is an uncommon disabling condition in young people involved in sports. Injury to the superior peroneal retinaculum, sometimes in association with a shallow fibular groove, can lead to this condition. There are several surgical treatments for recurrent peroneal tendon subluxation, but no tendoscopy technique has been reported to date. The aim of this study was to describe a tendoscopic groove-deepening technique and its results for treating patients with recurrent subluxation of the peroneal tendons. METHODS: Seven patients (3 women and 4 men; mean age 26.4 [21-32] years) with chronic subluxation of the peroneal tendons were treated with a tendoscopic procedure. All patients experienced pain at the lateral retromalleolar area and recurrent subluxation of the peroneal tendons. The right ankle was affected in 4 patients. Mean follow-up was 15.4 (8-25) months. RESULTS: On tendoscopic examination, all patients had a flat fibular groove, and the superior peroneal retinaculum was found to be detached in 4 cases. Three patients had a superficial injury of the peroneus brevis tendon which was debrided. Tendoscopic deepening of the peroneal groove without superior peroneal retinaculum repair was performed in all cases. None of the patients experienced recurrent subluxation during follow-up. The AOFAS score increased from 75 preoperatively to 93 at final follow-up. No complications were reported in any case. CONCLUSION: Tendoscopic deepening of the fibular groove was a reproducible, minimally invasive technique that provided a favorable outcome for recurrent subluxation of the peroneal tendons in our limited number of patients. LEVEL OF EVIDENCE: Level IV, retrospective case series.

RESUMO

Background: Primary repair of the anterior cruciate ligament (ACL) confers an alternative to ACL reconstruction in appropriately selected patients. Purpose: To prospectively assess survivorship and to define the clinically meaningful outcomes after ACL repair. Study Design: Case series; Level of evidence, 4. Methods: Included were consecutive patients with Sherman grade 1-2 tears who underwent primary ACL repair with or without suture augmentation between 2017 and 2019. Patient-reported outcomes (Lysholm, Tegner, International Knee Documentation Committee, Western Ontario and McMaster Universities Osteoarthritis Index, and Knee injury and Osteoarthritis Outcome Score [KOOS] subscales) were collected preoperatively and at 6 months, 1 year, and 2 years postoperatively. The minimal clinically important difference (MCID) was calculated using a distribution-based method, whereas the Patient Acceptable Symptom State (PASS) and substantial clinical benefit (SCB) were calculated using an anchor-based method. Plain radiographs and magnetic resonance imaging (MRI) were obtained at 6 months, 1 year, and 2 years postoperatively. Results: A total of 120 patients were included. The overall failure rate was 11.3% at 2 years postoperatively. Changes in outcome scores required to achieve the MCID ranged between 5.1 and 14.3 at 6 months, 4.6 and 8.4 at 1 year, and 4.7 and 11.9 at 2 years postoperatively. Thresholds for PASS achievement ranged between 62.5 and 89 at 6 months, 75 and 89 at 1 year, and 78.6 and 93.2 at 2 years postoperatively. Threshold scores (absolute/change based) for achieving the SCB ranged between 82.8 and 96.4/17.7 and 40.1 at 6 months, between 94.7 and 100/23 and 45 at 1 year, and between 95.3 and 100/29.4 and 45 at 2 years. More patients achieved the MCID and PASS at 1 year compared with 6 months and 2 years. For SCB, this trend was also observed for non-KOOS outcomes, while for KOOS subdomains, more patients achieved the SCB at 2 years. High-intensity signal of the ACL repair (odds ratio [OR], 31.7 [95% CI, 1.5-73.4]; P = .030) and bone contusions on MRI (OR, 4.2 [95% CI, 1.7-25.2]; P = .041) at 1 year postoperatively were independently associated with increased risk of ACL repair failure. Conclusion: The rate of clinically meaningful outcome improvement was high early after ACL repair, with the greatest proportion of patients achieving the MCID, PASS, and SCB at 1 year postoperatively. Bone contusions involving the posterolateral tibia and lateral femoral condyle as well as high repair signal intensity at 1 year postoperatively were independent predictors of failure at 2 years postoperatively.

RESUMO

We have synthesized cis-[Ru(bpy)2(NO2-κN)Ln-](n-1) and cis-[Ru(bpy)2(NO2-κO)L n-](n-1) (bpy = 2,2'-bipyridine; k = indication of the coordinated center to Ruthenium; L = pyridine type ligand) by reacting cis-[Ru(bpy)2(H2O)Ln-](n-2) with sodium nitrite or conducting basic cis-[Ru(bpy)2NO(Ln-)](n-3) hydrolysis. Photolysis at the metal-ligand charge transfer band (MLCT) of the isomers yielded nitric oxide (NO) as determined by NO measurement. The NO photorelease rates obtained upon 447 nm laser irradiation of the ruthenium complexes showed that cis-[Ru(bpy)2(NO2-κO)Ln-](n-1) released NO three times faster than cis-[Ru(bpy)2(NO2-κN)Ln-](n-1). We investigated endothelium-dependent vasodilation induced by cis-[Ru(bpy)2(4-pic)(NO2-κN)]+ and cis-[Ru(bpy)2(4-pic)(NO2-κO)]+ (4-pic = 4-picoline) in isolated 3 mm aortic rings precontracted with L-phenylephrine. Maximum vasodilation was achieved under 447 nm laser irradiation of 0.5 µMol.L-1 ruthenium complexes for 100 s.

RESUMO

Maternal obesity and dietary style in the pregnancy-lactation period may result in long-term effects on the metabolic health of the offspring, thus increasing the risk of diseases, such as obesity, diabetes, and cardiovascular diseases. Curcumin is a natural polyphenolic compound that has beneficial properties on metabolism. Accordingly, this study is intended to evaluate the effects of curcumin supplementation in pregnant and lactating female mice on the anthropometric, metabolic and molecular parameters of the offspring fed a hyperglycemic diet. The study was conducted with 24 male mice randomized into three groups: i) control group (SD) originating from dams fed a standard diet; ii) hyperglycemic group (HGD) originating from dams fed a hyperglycemic diet; iii) curcumin group (CUR) originating from dams fed a hyperglycemic diet and supplemented with curcumin in the pregnancy-lactation period. All offspring groups were fed a hyperglycemic diet for 12 weeks. Anthropometricand biochemical parameters were measured, as well as the expression of thermogenesis-associated markers in the interscapular brown and inguinal white adipose tissues. The results showed less weight gain in the CUR group, with a concomitant reduction in food consumption compared to the HGD group. Biochemical parameters indicated lower levels of total cholesterol, glucose, and insulin for the CUR group, in addition to improved glucose tolerance and insulin sensitivity. The molecular evaluation indicated increased mRNA expression levels of UCP1 and PRDM16 in the brown and white adipose tissues. It is concluded that curcumin supplementation in the pregnancy-lactation period in dams with diet-induced obesity may lead to improvements in the offspring's metabolic phenotype, even if they are submitted to an obesogenic environment, possibly via thermogenesis activation.

RESUMO

BACKGROUND: Both percutaneous and endoscopically assisted methods are reported to produce good results in the surgical management of acute Achilles tendon ruptures. The aim of this retrospective study was to compare between a percutaneous method and a recently described isolated endoscopically assisted flexor hallucis longus (FHL) transfer method as surgical means of management in patients with acute Achilles tendon ruptures. METHODS: One hundred seventeen patients were included in the current study and divided into 2 groups: 59 patients who underwent percutaneous Achilles repair (PAR Group) and 58 patients who underwent isolated endoscopic FHL transfer (FHL Group) were compared. Patients were clinically evaluated using American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, Achilles tendon Total Rupture Score (ATRS), and Achilles tendon resting angle (ATRA) measures. In addition, ankle plantarflexion power, FHL dynamometry, Tegner activity levels, and return to previous levels of activity were also documented for all patients. RESULTS: Nine months after surgery, patients in the FHL transfer group were more likely to be able to return to normal activities (91% vs 73%, P < .01). Thirty months after surgical treatment, we found no difference in ATRS, AOFAS, ATRA, ankle plantarflexion strength, or Tegner activity scores between study groups. Overall complications were reported in 6 patients in the FHL group (10.3%) and in 8 patients in the PAR group (13.6%). No major neurovascular or skin complications were encountered. CONCLUSION: The current study demonstrated satisfactory and comparable results and complications when comparing isolated endoscopic FHL tendon transfer or percutaneous Achilles tendon repairs in the surgical management of acute Achilles tendon ruptures. LEVEL OF EVIDENCE: Level III, retrospective controlled trial.

RESUMO

BACKGROUND: Acute Achilles tendon ruptures (AATRs) that occur in athletes can be a career-ending injury. The aim of this study was to describe return to play and clinical outcomes of isolated endoscopic flexor hallucis longus (FHL) transfer in active soccer players with AATR. METHODS: Twenty-seven active male soccer players who underwent endoscopically assisted FHL tendon transfer for acute Achilles tendon ruptures were included in this study. Follow up was 46.2 (±10.9) months after surgery. Return to play criteria and clinical outcome measures were evaluated. RESULTS: All players returned to playing professional competitive soccer games. Return to active team training was at a mean of 5.8 (±1.1) months postoperatively. However, return to active competitive match play occurred at a mean of 8.3 (±1.4) months. Twenty-two players (82%) were able to return to their preinjury levels and performances and resumed their professional careers at the same soccer club as their preinjury state. One player (3.7%) shifted his career to professional indoor soccer. At 26 months postoperatively, the mean Tegner activity scale score was 9.7 (±0.4), the mean Achilles tendon total rupture score was 99 (±2), and the mean American Orthopaedic Foot & Ankle Society ankle-hindfoot score was 99 (±3). No patients reported any great toe complaints or symptomatic deficits of flexion strength. CONCLUSION: The current study demonstrated satisfactory and comparable return to play criteria and clinical results with minimal complications when using an advanced endoscopically assisted technique involving FHL tendon transfer to treat acute Achilles tendon ruptures in this specific subset of patient cohort. LEVEL OF EVIDENCE: Level II, prospective cohort case series study.

RESUMO

BACKGROUND: The evidence supporting best practice guidelines in the field of cartilage repair of the ankle is based on both low quality and low levels of evidence. Therefore, an international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to report the consensus statements on "terminology for osteochondral lesions of the ankle" developed at the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. METHODS: Forty-three international experts in cartilage repair of the ankle representing 20 countries were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within four working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed, and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed on in unanimous fashion within the working groups. A final vote was then held, and the strength of consensus was characterised as follows: consensus, 51%-74%; strong consensus, 75%-99%; unanimous, 100%. RESULTS: A total of 11 statements on terminology and classification reached consensus during the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. Definitions are provided for osseous, chondral and osteochondral lesions, as well as bone marrow stimulation and injury chronicity, among others. An osteochondral lesion of the talus can be abbreviated as OLT. CONCLUSIONS: This international consensus derived from leaders in the field will assist clinicians with the appropriate terminology for osteochondral lesions of the ankle.

RESUMO

BACKGROUND: An international consensus group of experts was convened to collaboratively advance toward consensus opinions based on the best available evidence on key topics within cartilage repair of the ankle. The purpose of this article is to present the consensus statements on osteochondral lesions of the tibial plafond (OLTP) and on ankle instability with ankle cartilage lesions developed at the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. METHODS: Forty-three experts in cartilage repair of the ankle were convened and participated in a process based on the Delphi method of achieving consensus. Questions and statements were drafted within 4 working groups focusing on specific topics within cartilage repair of the ankle, after which a comprehensive literature review was performed and the available evidence for each statement was graded. Discussion and debate occurred in cases where statements were not agreed on in unanimous fashion within the working groups. A final vote was then held. RESULTS: A total of 11 statements on OLTP reached consensus. Four achieved unanimous support and 7 reached strong consensus (greater than 75% agreement). A total of 8 statements on ankle instability with ankle cartilage lesions reached consensus during the 2019 International Consensus Meeting on Cartilage Repair of the Ankle. One achieved unanimous support, and seven reached strong consensus (greater than 75% agreement). CONCLUSION: These consensus statements may assist clinicians in the management of these difficult clinical pathologies. LEVEL OF EVIDENCE: Level V, mechanism-based reasoning.

RESUMO

The incidence of post-COVID-19 cardiac compromise is not well known. The eventual cardiac repercussions on a return to high-performance sport are unclear. A prospective observational study with evaluation by physical examination, electrocardiogram, Doppler echocardiogram and cardiac magnetic resonance imaging (CMR) was carried out in international level professional soccer players recovering from COVID-19 who had the disease asymptomatic or with mild symptoms. Four-month follow-up with participation in national and international competitions. Twenty-four soccer players were included, age 27.13 years (between 20 and 36). Nine (37.5%) had asymptomatic disease and 15 (62.5%) had mild symptoms. No athletes required hospitalization. Physical, electrocardiographic, and echocardiographic examinations did not reveal heart disease. CMRs showed ventricular thicknesses and volumes consistent with high-performance athletes. In T1, T2 and fat saturation signals, no fat infiltration or signs of edema were observed. No late enhancement after gadolinium injection. They began their training between 12 and 14 days after diagnosis. Eleven (45.8%) participated between 4 and 6 international matches of Libertadores de América International Cup. The remaining 13 completed high intensity training sessions and participated in local league competitions. At 4 months after diagnosis, none of the soccer players developed cardiac events and training and competitions were well tolerated. These findings suggest low cardiovascular impact of COVID 19 and excellent tolerance to early post-COVID high intensity exercise of young athletes recovering from the disease with no or mild symptoms.


La incidencia de compromiso cardíaco post COVID-19 en pacientes que cursaron la enfermedad asintomáticos o con síntomas leves no es bien conocida. Tampoco están claras las eventuales repercusiones cardíacas en el regreso al deporte de alto rendimiento. Se realizó un estudio observacional prospectivo con evaluación mediante electrocardiograma, ecocardiograma Doppler y resonancia magnética cardiaca (RMC) a hombres futbolistas profesionales de nivel internacional que habían cursado COVID-19 asintomáticos o con síntomas leves; seguimiento 4 meses con participación en competencias nacionales e internacionales. Se incluyeron 24 futbolistas, edad media 27, (20-36). Nueve (37.5%) cursaron la enfermedad asintomáticos y 15 (62.5%) con síntomas leves. Los exámenes físicos, electro y ecocardiográficos no evidenciaron cardiopatía. Las RMCs mostraron espesores y volúmenes ventriculares acordes a deportistas de alto rendimiento. En las señales de T1, T2 y saturación grasa no se observó infiltración grasa ni signos de edema; sin realce tardío post inyección de gadolinio. Comenzaron sus entrenamientos entre 12 y 14 días post diagnóstico. Once (45.8%) participaron entre 4 y 6 encuentros internacionales de la Copa Libertadores de América. Los restantes 13 cumplieron con entrenamientos de alta intensidad y participaron en competencias de liga local. A 4 meses del diagnóstico ninguno de los futbolistas desarrolló eventos cardíacos y los entrenamientos y competencias fueron bien tolerados. Estos hallazgos sugieren la escasa repercusión cardiovascular de COVID-19 y la excelente tolerancia al ejercicio de alta intensidad realizado en forma precoz post COVID de deportistas jóvenes que cursaron la enfermedad asintomáticos o con síntomas leves.

RESUMO

OBJECTIVE: Fifth metatarsal fractures occur mainly in young athletes, with an estimated incidence of 1.8 per 1000 individuals per year. This study aims to evaluate the functional outcome of professional soccer players undergoing surgical treatment of fifth metatarsal base fractures. METHODS: We appraised 34 soccer players operated on from July 2001 to June 2016. All individuals were assessed by the American Orthopedic Foot and Ankle Score (AOFAS) and Visual Analog Scale (VAS) before and after surgery, with a mean 23-month follow-up. The need for grafting, fracture healing, Torg classification, and return to sports were also evaluated. RESULTS: There were 10 attackers, 7 offensive-defensive midfielders, 6 side defenders, 5 central defensive midfielders, 3 defenders, 2 goalkeepers, and 1 defensive midfielder, at an average age of 19 years. Preoperative and postoperative AOFAS averaged 42 and 99 points, respectively, whereas VAS scores were 6 and 0. The longer the time to get operated on, the greater was the need for grafting (P = .011). In our study, all fractures have consolidated. Return to sports occurred, on average, 73 days after surgical treatment, and it was not influenced by the time to get operated on, fracture healing, Torg classification, and grafting. CONCLUSION: Surgical treatment of the fifth metatarsal base fracture in professional soccer players presents good clinical results. Getting back to activities after surgery is not influenced by surgery time, fracture healing, Torg classification, and grafting.Levels of Evidence: Level IV: Therapeutic studies, Case series.
