Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games.

OBJECTIVES: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. METHODS: Data were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. RESULTS: A total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. CONCLUSION: Shoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport.

Can three-dimensional models enhance understanding and knowledge of rotator cuff tears?

OBJECTIVES: Magnetic resonance imaging (MRI) is currently the standard diagnostic tool for rotator cuff tears. However, its two-dimensional (2D) output, displayed on a monitor, can complicate the interpretation of anatomy. Three-dimensional (3D) imaging may offer a solution to this issue. This study aimed to demonstrate the diagnostic and interpretive value of a 3D model in assessing lesion anatomy. The hypothesis was that 3D models, compared to 2D MRI, can enhance the comprehension and knowledge of rotator cuff injuries, improve the application of classifications for total tears, and provide a more precise definition of the size and type of tear. METHODS: A prospective single-centre study was conducted. 3D models for rotator cuff tears were created and analysed in conjunction with preoperative MRI for each patient up to 2 months before surgery. The 3D models were based on the preoperative MRI. Collected data included 2D plane measurements by MRI in coronal and sagittal planes, descriptions of 3D lesion geometry (new shapes), 3D measurements in coronal and sagittal planes, arthroscopic classifications of rotator cuff injuries, and arthroscopic measurements in coronal and sagittal planes. RESULTS: After examining 25 cases, 3D imaging demonstrated similar arthroscopic values post-bursectomy in the sagittal plane (16.70 â€‹mm for 3D and 18.28 â€‹mm for post-bursectomy, p-value â€‹= â€‹0.189), although these measurements did not align with those of MRI (which underestimated measurements, p-value â€‹= â€‹0.010). Both MRI measurement and 3D imaging showed similar measurement accuracy in the coronal plane when compared to arthroscopic measurements taken before and after bursectomy. The creation of 3D objects enabled the analysis of new geometries, including the length, width, and depth of each lesion. These geometries included the rectangle, rectangular trapezoid, scalene trapezoid, irregular pentagon, and irregular hexagon. CONCLUSIONS: 3D models can enhance the understanding and knowledge of rotator cuff injuries. They can be a promising tool for diagnosing and interpreting the anatomy of the injury, particularly in the sagittal plane. The new 3D understanding of the pathological process has led to the description of new geometric features not visible in conventional 2D MRI. LEVEL OF EVIDENCE: II - Development of diagnostic criteria on consecutive patients (all compared to "gold" standard).

FUNCTIONAL ASSESSMENT OF THE SHOULDER IN JIU-JITSU BLACK BELT ATHLETES.

OBJECTIVE: To assess the epidemiological profile of Jiu-Jitsu black belt athletes, including the prevalence of pain and shoulder function. METHODS: Cross-sectional study carried out with Jiu-Jitsu athletes from 2014 to 2016. The studied variables were: sex, age, dominant limb, weight, height, profession, time of Jiu-Jitsu practice, weekly training hours, other practiced sports, comorbidities, injuries and previous surgeries, medications and habits. For the functional assessment of the shoulder, the ASES Score was used. RESULTS: 53 male athletes were evaluated. There was a prevalence of alcohol consumption (60.4%) and supplement use (32.1%). The practice of other sports included weight training (49.1%) and other martial arts (17%). There was a prevalence of knee (66.0%) and shoulder (52.8%) injuries and, in some cases, the need for surgical procedures. There was a prevalence of shoulder pain (73.6%) and more than half of the athletes (52.9%) had minimal or moderate limitation of shoulder function. CONCLUSION: Jiu-jitsu black belt athletes often have a history of injuries, with the shoulder being the second most affected body part. In more than half of the athletes, there was a prevalence of shoulder pain and functional limitation, according to the ASES Score. Level of evidence III, Retrospective comparative study.

Changes in the methodology of medical teaching due to the COVID-19 pandemic.

OBJECTIVE: To evaluate the perceptions of students and teachers regarding remote teaching modality in comparison with the traditional face-to-face method. METHODS: In this observational, retrospective, comparative, single-center study, questionnaires containing three major assessment domains were sent to two groups: university professors and undergraduate and graduate students. The first domain collected demographic and general data on the platforms used. The second and third domains contained questions that compared the perception of the quality of information offered by the two systems. RESULTS: Between May and September 2020, 162 students and 71 teachers participated in the study. A greater proportion of students demonstrated previous contact with the online method, while professors had presented a greater number of courses. Most participants reported that their expectations regarding the remote teaching method were met (students, 80.3%; teachers, 94.4%). A significant number of students (83.3%) and teachers (88.7%) rated the classes as easier to attend and manage. Despite difficulties, such as concentration retention, most of the participants agree (at least partially) that the format should be maintained. CONCLUSION: The remote teaching methodology, although still incipient in Brazil, has become a reality in light of current health restrictions. Our study demonstrated a high level of overall satisfaction and a high sense of learning from both students and faculty. However, new challenges associated with this system have been identified, such as retention of attention and interference from the external environment. Longitudinal comparative studies that incorporate various aspects of medical education in all cycles are necessary to corroborate the findings of this study. DESIGN: Retrospective comparative study, level III evidence.

Medical planning for mass gathering sports events in brazil / Planificación médica para eventos deportivos masivos en brasil / Planejamento médico para eventos esportivos de massa no brasil

ABSTRACT Introduction: Medical planning for mass gathering events is founded on the structuring of assistance to the population involved and the preservation of the response capacities of the local healthcare system. Large sporting events attended by crowds are increasingly common in society. These events have been shown to be dangerous, generating higher incidences of injuries and illnesses than usual. Thus, planning and the interaction among various public and private sectors are required for the prevention of and response to emergencies and incidents involving multiple victims. Methods: Recently published studies on medical planning for large sports events and current federal agency legislation were selected to conduct an updated review on the subject. Results: After reading titles and abstracts, 159 papers were chosen for a full reading, 50 of which met the eligibility criteria and were included as the basis for this review. The size of the audience, the weather, and the behavior of the crowd seem to contribute significantly to the estimated need for resources in sporting events. Conclusion: Mass events require planning for prevention and to strengthen the resilience of host communities. There is a still a lack of evidence that these events increase the risk of the mass spreading of disease. Level of Evidence: V; Expert opinion .

Epidemiology of Upper Limb Injuries in two major Brazilian Soccer Championships from 2016 to 2019.

PURPOSE: To evaluate epidemiological data of upper limb injuries in professional athletes who participated in two major Brazilian soccer championships between 2016 and 2019. METHODS: A prospective cohort study was conducted to evaluate the teams of two divisions over four seasons within the Brazilian Soccer Championship and the Paulista Soccer Championship. Clubs and their doctors were contacted to participate in the study and guided on the correct way to enter data via online platforms: Transfermarkt (Transfermarkt GmbH & Co. KG) and Survey Monkey (Momentive.AI). Demographic data, injury characteristics, and FIFA Incidence Formula were analyzed. RESULTS: Overall, the study analyzed 3,828 matches and 126,357 hours of play. Upper limb injuries were registered 169 times, representing 6.8% of total injuries, with a FIFA incidence of 1.34. Most lesions occurred in forward players (21.3%), the shoulder exhibited the highest number of injuries (63.3%). The player's position was related to the location on the field where the injury occurred (p < 0.001); however, there was no relationship between the type of injury and the location on the body (p > 0.001). The average time to return to play was 19.1 days (range 0-200 days) and it was longer for goalkeepers. The necessity of surgical treatment was statistically associated with additional time to return to play (p < 0.001). CONCLUSIONS: Shoulder injuries were the most frequent upper limb injury sustained during the two major Brazilian soccer championships. Forward players suffered the most upper limb injuries and goalkeepers experienced the longest time to return to play.

What is the best position for coracoid fixation in the Latarjet procedure?

Hypothesis: Multiple problems and complications associated with Latarjet fixation have been described; thus, this is the first study in the literature to identify the maximum allowed screw clamping force and best fixation screw position for Latarjet surgery. Methods: A variation of distal and proximal coracoid screw positions with and without a flat washer was evaluated through finite element analysis, at a minimum distance of 3 mm from the edge. A loading progression test was performed until the maximum stress reached a limit imposed by the bone yield. We identified the maximum allowed screw clamping force based on a von Mises and maximum principal stresses failure theory. Results: When using the flat washer, the cortical bone generally has only space for 1 piece. For this reason, as a primary study, it was observed that when the distal screw was more than 7 mm from the edge, the clamping force supported will be higher than that during the proximal fixation regardless of the proximal location screw. We have found that the best position is 7 mm from the distal edge, with the highest compression of 445 N (7 mm proximal distance, 5 mm distal distance) in due respect to the von Mises failure theory. To get around this lack of space situation, in this study, we have proposed a fixation plate to replace the flat washer. This plate has shown very interesting values when compared to the previously flat washer study, but now, for both screw holes. With those results, we can assure that using a fixation plate like this will ensure surgery safety and higher allowed compression force when clamping the bolts. Conclusion: The distal screw provided higher tensile strength values when located more than 7 mm from the coracoid edge. The geometry of the coracoid in its distal position supports higher stress loads than in the proximal position. When the flat washer was in the proximal position, the coracoid was submitted with a more distributed and uniform load, preventing localized bone damage as a crush.

Surgical repair of the medial head of the gastrocnemius: two case reports and review.

The gastrocnemius medial head distal musculotendinous junction injury is relatively common. Musculature contraction in an already stretched structure leads to muscle breakdown. Patients affected are often physically active middle-aged men. The typical presentation includes sudden pain, audible popping, bruising and localized tenderness. Occasionally, there is a palpable defect if the rupture is complete. Although the initial diagnosis can be made on the basis of a careful history and clinical examination, ultrasound or magnetic resonance imaging can be used to better describe the lesion. In complete ruptures, even when conservative treatment shows good results, it is common that the patient presents decreased muscle strength, difficulty returning to sports and permanent and visible gap. Considering surgical treatment in patients with complete ruptures and extensive injuries with a more than 5 cm gap may lead to better healing process, rapid rehabilitation and more efficient return to sports.

Rotator Cuff Lesion and Obesity: A Demographic and Metabolic Evaluation.

Objective To analyze the relationship between the presence and severity of rotator cuff (RC) injury with obesity and the time of exposure to obesity. Secondarily, to evaluate the relationship and prevalence of demographic and metabolic factors in obese individuals with RC injury. Methods This is a cross-sectional study with 235 obese patients (body mass index [BMI] ≥ 30 kg/m 2 ). Demographic data (age and gender), metabolic data (hypertension, diabetes mellitus, lipid profile, and time of exposure to obesity), physical examination (weight, height, waist circumference, and clinical tests), and musculoskeletal ultrasound examination were used to analyze the results. Results There was no evidence of an association between RC injury and BMI ( p = 0.82), time of exposure to obesity ( p = 0.29), or abdominal circumference ( p = 0.52). In the subgroup with injury, age ( p < 0.001), presence of diabetes mellitus ( p = 0.013), hypertension ( p < 0.001), level of high-density lipoprotein (HDL) ( p = 0.026), and time of exposure to obesity ( p < 0.001) were significantly greater compared to the subgroup without injury. In the search for other parameters independently associated with RC injury, associations were observed with age ( p = 0.0003) and hypertension ( p = 0.004). Conclusion We did not evidence an association between obesity and the time of exposure to it with the occurrence and severity of RC injury. However, individuals with injury had a longer time of exposure to obesity and prevalence of metabolic disorders than individuals without RC injury. In addition, our findings suggest an association between systemic arterial hypertension (SAH) and advanced age with RC injury.

HYLAN G-F 20 VERSUS TRIAMCINOLONE IN THE TREATMENT OF PRIMARY SHOULDER OSTEOARTHRITIS. RANDOMIZED TRIAL.

Introduction: The aim of this study was to evaluate the effect of using an intra-articular injection of hylan G-F 20 (HA group) on primary shoulder osteoarthritis compared with an intra-articular triamcinolone injection (T group). Materials and Methods: The patients were randomized into 2 groups: in the HA group a single dose of intra-articular hylan G-F 20 was administered and in the T control group a dose of triamcinolone 20 mg was administered. The participants were evaluated at 1 week, 1, 3, and 6 months after the procedure. The patients were evaluated for pain, range of motion, Constant score, modified UCLA score, and SPADI. Results: Seventy patients met the inclusion criteria and were randomized to the HA (38) and T (32) groups. Improvements in range of motion were significant (p > 0.05). We observed decreases in the general visual analog scale (VAS) for pain in both groups, especially in the cases of mild and moderate arthritis that received hyaluronic acid (mean values from 8.1 initially to 4.9 after 6 months) (p = 0). Conclusions: Both injections led to a decrease in pain and an increase in patient satisfaction. The results tend to be better and longer lasting in patients receiving hyaluronic acid. Level of evidence II b; Cohort study.

Material e Método: Os pacientes foram randomizados em dois grupos: no Grupo HA foi administrada uma dose única de Hilano G-F 20 intra-articular e no Grupo controle T foi administrada uma dose de 20 mg de triancinolona. Os participantes foram avaliados 1 semana, 1, 3 e 6 meses depois do procedimento. Os pacientes foram avaliados quanto à dor, amplitude de movimento, escore de Constant, escore UCLA modificado e índice SPADI. Resultados: Setenta pacientes satisfizeram os critérios de inclusão e foram randomizados para os Grupos HA (38) e T (32). As melhoras da amplitude de movimento foram significativas (p > 0,05). Observamos diminuições na escala visual analógica (EVA) geral para dor em ambos os grupos, principalmente nos casos de artrite leve e moderada que receberam ácido hialurônico (valores médios de 8,1 inicialmente a 4,9 depois de 6 meses) (p = 0). Conclusões: Ambas as injeções reduziram a dor e aumentaram a satisfação do paciente. Os resultados tendem a ser melhores e mais duradouros em pacientes que recebem ácido hialurônico.

Resumo Objetivo Analisar a relação da presença e da gravidade da lesão do manguito rotador (MR) com a obesidade e o tempo de exposição à obesidade. De forma secundária, avaliar a relação e a prevalência de fatores demográficos e metabólicos em indivíduos obesos com lesão do MR. Métodos Trata-se de um estudo transversal, com 235 pacientes obesos (índice de massa corporal [IMC] 30 kg/m2). Dados demográficos (idade e gênero), metabólicos (hipertensão, diabetes mellitus, perfil lipídico, e tempo de exposição à obesidade), exame físico (peso, estatura, circunferência abdominal, e testes clínicos), e exame ultrassonográfico musculoesquelético foram utilizados para a análise dos resultados. Resultados Não foi evidenciada associação da lesão do MR com IMC (p » 0,82), tempo de exposição à obesidade (p » 0,29), ou circunferência abdominal (p » 0,52). No subgrupo com lesão, a idade (p < 0,001), a presença de diabetes melito (p » 0,013), a hipertensão (p < 0,001), o nível de lipoproteína de alta densidade (high-density lipoprotein, HDL, em inglês) (p » 0,026), e o tempo de exposição à obesidade (p < 0,001) foram significativamente maiores em comparação ao subgrupo sem lesão do MR. Na busca por demais parâmetros associados de forma independente para lesão do MR, foram observadas associações com idade (p » 0,0003) e hipertensão (p »0,004). Conclusão Não evidenciamos associação da obesidade e do tempo de exposição a ela coma ocorrência e a gravidadeda lesãodo MR. Porém, indivíduos comlesão apresentaram maior tempo de exposição à obesidade e prevalência de disfunções metabólicas do que indivíduos sem lesão. Além disso, nossos achados sugerem uma associação entre hipertensão arterial sistêmica (HAS) e idade avançada com a lesão do MR.

A Simple Technique to Restore Tension of a Loose Suture Bridge During Rotator Cuff Repair: Save the Repair.

The transosseous equivalent suture bridge technique has been widely used for rotator cuff repair, especially for large tears. During the fixation of the second lateral anchor, the first group of sutures may become loose due to anchor malposition or manual overtensioning of the second group of sutures. To restore the suture's tension, a spare suture from the second lateral anchor may be passed beneath the loose suture to tighten it with a simple knot. This technique has been shown to be easy and fast to perform and does not require extra material.

Isokinetic Evaluation of the Shoulder After Bristow/Latarjet Surgical Procedure in Athletes.

Objectives To evaluate the muscular strength of the internal (IR) and external (ER) rotators of the shoulder after Bristow/Latarjet surgery. Methods Cross-sectional study with 18 patients (36 shoulders). The isokinetic evaluation was performed using the Biodex 3 System Pro dynamometer (Biodex Medical System, Inc., Shirley, NY, USA). The athletic shoulder outcome rating scale (ASORS) and the visual analogue scale (VAS) were applied. Results The values of peak torque and maximum work in concentric and eccentric mode on the non-operated shoulder were higher than on the operated side for both the IR and ER ( p < 0.01). The conventional and functional balance between the ER and IR showed no differences between the operated and the non-operated side. When comparing patients with postoperative time < 1 year or 1 year, no differences were observed in peak torque values at 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the IR to the operated shoulder. However, the peak torque values of 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the ER were higher in subjects with postoperative time ≥ 1 year in all variables ( p < 0.05). Conclusions There was a decrease in the strength of the IR and ER in the operated shoulder compared with the healthy shoulder. However, the conventional and functional balance was maintained.

However, the peak torque values of 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the ER were higher in subjects with postoperative time ≥ 1 year in all variables (p< 0.05). Conclusions There was a decrease in the strength of the IR and ER in the operated shoulder compared with the healthy shoulder. However, the conventional and functional balance was maintained.

Resumo Objetivos Avaliar a força muscular dos rotadores medial (RM) e lateral (RL) do ombro após cirurgia de Bristow/Latarjet. Métodos Estudo transversal com 18 pacientes (36 ombros). A avaliação isocinética foi realizada por meio do dinamômetro Biodex 3 System Pro (Biodex Medical System, Inc., Shirley, NY, EUA). A escala de avaliação dos resultados do ombro do esportista (EROE) e a escala visual analógica (EVA) da dor foram aplicadas. Resultados Os valores do pico de torque e o trabalho máximo no modo concêntrico e excêntrico no ombro não-operado foram maiores que no lado operado, tanto para o RM e como para o RL (p< 0,01). O equilíbrio convencional e funcional entre o RL e o RM não apresentou diferenças entre o lado operado e o não operado. Na comparação entre pacientes com o tempo pós-operatório < 1 ano ou ≥ 1 ano, não se observou diferenças nos valores do pico de torque em 60°/s e 240°/s e do trabalho máximo em 60°/s e 240°/s do RM para o ombro operado. No entanto, os valores de do pico de torque em 60°/s e 240°/s e do trabalho máximo em 60°/s e 240°/s do RL foram superiores em indivíduos com tempo pós-cirúrgico ≥ 1 ano em todas as variáveis (p< 0,05). Conclusões Houve diminuição da força do RM e do RL no ombro operado em relação ao ombro saudável; porém, o equilíbrio convencional e funcional foi mantido.

Hylan g-f 20 versus triamcinolone in the treatment of primary shoulder osteoarthritis. randomized trial / Hilano g-f 20 versus triancinolona no tratamento da osteoartrite primária do ombro. estudo randomizado

ABSTRACT Introduction The aim of this study was to evaluate the effect of using an intra-articular injection of hylan G-F 20 (HA group) on primary shoulder osteoarthritis compared with an intra-articular triamcinolone injection (T group). Materials and Methods The patients were randomized into 2 groups: in the HA group a single dose of intra-articular hylan G-F 20 was administered and in the T control group a dose of triamcinolone 20 mg was administered. The participants were evaluated at 1 week, 1, 3, and 6 months after the procedure. The patients were evaluated for pain, range of motion, Constant score, modified UCLA score, and SPADI. Results Seventy patients met the inclusion criteria and were randomized to the HA (38) and T (32) groups. Improvements in range of motion were significant (p > 0.05). We observed decreases in the general visual analog scale (VAS) for pain in both groups, especially in the cases of mild and moderate arthritis that received hyaluronic acid (mean values from 8.1 initially to 4.9 after 6 months) (p = 0). Conclusions Both injections led to a decrease in pain and an increase in patient satisfaction. The results tend to be better and longer lasting in patients receiving hyaluronic acid. Level of evidence II b; Cohort study.

RESUMO Introdução O objetivo deste estudo foi avaliar o efeito do uso de uma injeção intra-articular de Hilano G-F 20 (Grupo HA) na osteoartrite primária do ombro em comparação com injeção intra-articular de triancinolona (Grupo T). Material e Método Os pacientes foram randomizados em dois grupos: no Grupo HA foi administrada uma dose única de Hilano G-F 20 intra-articular e no Grupo controle T foi administrada uma dose de 20 mg de triancinolona. Os participantes foram avaliados 1 semana, 1, 3 e 6 meses depois do procedimento. Os pacientes foram avaliados quanto à dor, amplitude de movimento, escore de Constant, escore UCLA modificado e índice SPADI. Resultados Setenta pacientes satisfizeram os critérios de inclusão e foram randomizados para os Grupos HA (38) e T (32). As melhoras da amplitude de movimento foram significativas (p > 0,05). Observamos diminuições na escala visual analógica (EVA) geral para dor em ambos os grupos, principalmente nos casos de artrite leve e moderada que receberam ácido hialurônico (valores médios de 8,1 inicialmente a 4,9 depois de 6 meses) (p = 0). Conclusões Ambas as injeções reduziram a dor e aumentaram a satisfação do paciente. Os resultados tendem a ser melhores e mais duradouros em pacientes que recebem ácido hialurônico.

ECONOMIC IMPACT OF COVID-19 ON BRAZILIAN ORTHOPEDISTS.

OBJECTIVE: The aim of this study is to assess the economic impact of the new coronavirus (COVID-19) on Brazilian Orthopaedic Surgeons. METHODS: The questionnaire was applied to orthopedists and it questions how long they have worked in this area; their monthly financial impact during the pandemic; what sector was impacted the most; if they had or didn't have any financial reserves and how long they would last; if they had any other source of fixed income; and how much time off they had taken from work. It was entirely anonymous and it could only be answered once. RESULTS: About 98% (955 out of 975) of the analyzed orthopedists suffered some monetary impact, 80% had a financial reserves, from which 45% could last for 3 months. CONCLUSION: There was a direct relationship between the professional experience in this subspecialty and a higher percentage of fixed income, as well as a greater impact on the reduction percentage in the monthly budget and a longer time off the job.

Arthroscopic Superior Capsule Reconstruction Using Three-Dimensional Preoperative Planning: Technique Description.

We describe a technique using a fascia lata autograft with 3-dimensional (3D) printing to reconstruct the rotator cuff. Prototyping constitutes the construction of physical prototypes with high complexity after virtual studies. Such models increase the knowledge of the characteristics and size of rotator cuff injuries, thus improving the accuracy of determining the correct size of the graft to be used in superior capsule reconstruction. We present a case of superior capsule reconstruction using 3D printing for enhancing the accuracy of fascia lata allograft size and tension determination; 3D reconstruction has never been described in the literature for rotator cuff injuries.
