Abstract
Rotator cuff (RC) and long head of the biceps tendon (LHBT) tears are common shoulder problems presented to the orthopedic clinic. The aim of this study was to assess the association between RC and LHBT tears among a Saudi population sample. A total of 243 patients who were diagnosed with shoulder pain due to RC or LHBT tear between 2016 and 2018 using a magnetic resonance imaging scan were included in this study. Females comprised 66% of the sample, and 59% (n = 143) of the shoulders were on the right side. The mean age of the patients was 58 ± 11 years, ranging from 23 to 88 years. A significant association was detected between the LHBT and RC tears (P < 0.001). Out of 26 cases showing RC and LHBT tears, 81% had a full thickness tear, whereas 19% had a partial tear. The LHBT tears were presented significantly in 48% of cases with at least two completely torn RC compared to 10% in cases with one completely torn RC (P < 0.001). The LHBT tear was significantly observed in shoulders with RC tears including the tendons of subscapularis, supraspinatus, and infraspinatus, but not the teres minor (P < 0.001). Both types of tears were presented significantly in senior patients aged more than 65 years compared to younger patients (P < 0.01). Thus, the LHBT should be assessed carefully in shoulders with more than one RC tear or in chronic cases.

Abstract
The concept that the culprit lesion in non-ST segment elevation myocardial infarction (NSTEMI) is caused by sudden plaque rupture with acute thrombus formation has recently been challenged. While angiography is an old gold-standard for culprit identification it merely visualizes the lumen contour. Optical coherence tomography (OCT) provides a detailed view of culprit features. Combined with myocardial edema on cardiac magnetic resonance (CMR), indicating acute ischemia and thus culprit location, we aimed to characterize culprit lesions using OCT. Patients with NSTEMI referred for angiography were prospectively enrolled. OCT was performed on angiographic stenoses ≥50% and on operator-suspected culprit lesions. Hierarchical OCT-culprit identifiers were defined in case of multiple unstable lesions, including OCT-defined thrombus age. An OCT-based definition of an organizing thrombus as corresponding to histological early healing stage was introduced. Lesions were classified as OCT-culprit or non-culprit, and characteristics compared. CMR was performed in a subset of patients. We included 65 patients with 97 lesions, of which 49 patients (75%) had 53 (54%) OCT-culprit lesions. The most common OCT-culprit identifiers were the presence of acute (66%) and organizing thrombus (19%). Plaque rupture was visible in 45% of OCT-culprit lesions. CMR performed in 38 patients revealed myocardial oedema in the corresponding territories of 67% of acute thrombi and 50% of organizing thrombi. A culprit lesion was identified by OCT in 75% patients with NSTEMI. Acute thrombus was the most frequent feature followed by organizing thrombus. Applying specific OCT-criteria to identify the culprit could prove valuable in ambiguous cases.

Abstract
CLINICAL/METHODOLOGICAL PROBLEM The rotator cuff is a complex anatomical structure and the integrity is pivotal for the shoulder functionality. The pathologies are often multifactorial, resulting from degenerative, vascular, traumatic and mechanical factors. RADIOLOGICAL STANDARD PROCEDURES Radiography, ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) form the pillars of radiological diagnostics. Each modality has specific advantages and limitations in the visualization and assessment of pathologies of the rotator cuff and biceps tendon. METHODOLOGICAL INNOVATIONS The MR arthrography offers additional insights in unclear cases by enhancing the differentiation between complete and partial tears. PERFORMANCE The MRI provides detailed information on tendon quality and associated damages, such as muscle atrophy and fat infiltration, making it the preferred method. The use of MR arthrography can identify defects through increased intra-articular pressure or contrast medium leakage. EVALUATION Muscle damage, as induced by edema in acute injuries or fatty degeneration in chronic conditions, can be evaluated using imaging techniques. Special attention is warranted for the infraspinatus, subscapularis and teres minor muscles due to their unique injury patterns and prevalences.

Abstract
AIMS Coronary microevaginations (CMEs) represent an outward bulge of coronary plaques and have been introduced as a sign of adverse vascular remodelling following coronary device implantation. However, their role in atherosclerosis and plaque destabilization in the absence of coronary intervention is unknown. This study aimed to investigate CME as a novel feature of plaque vulnerability and to characterize its associated inflammatory cell-vessel-wall interactions. METHODS AND RESULTS A total of 557 patients from the translational OPTICO-ACS study programme underwent optical coherence tomography imaging of the culprit vessel and simultaneous immunophenotyping of the culprit lesion (CL). Two hundred and fifty-eight CLs had a ruptured fibrous cap (RFC) and one hundred had intact fibrous cap (IFC) acute coronary syndrome (ACS) as an underlying pathophysiology. CMEs were significantly more frequent in CL when compared with non-CL (25 vs. 4%, P < 0.001) and were more frequently observed in lesions with IFC-ACS when compared with RFC-ACS (55.0 vs. 12.7%, P < 0.001). CMEs were particularly prevalent in IFC-ACS-causing CLs independent of a coronary bifurcation (IFC-ICB) when compared with IFC-ACS with an association to a coronary bifurcation (IFC-ACB, 65.4 vs. 43.7%, P = 0.030). CME emerged as the strongest independent predictor of IFC-ICB (relative risk 3.36, 95% confidence interval 1.67-6.76, P = 0.001) by multivariable regression analysis. IFC-ICB demonstrated an enrichment of monocytes in both culprit blood analysis (culprit ratio: 1.1 ± 0.2 vs. 0.9 ± 0.2, P = 0.048) and aspirated culprit thrombi (326 ± 162 vs. 96 ± 87 cells/mm2, P = 0.017), while IFC-ACB confirmed the accumulation of CD4+ T cells, as recently described. CONCLUSION This study provides novel evidence for a pathophysiological involvement of CME in the development of IFC-ACS and provides first evidence for a distinct pathophysiological pathway for IFC-ICB, driven by CME-derived flow disturbances and inflammatory activation involving the innate immune system. TRIAL REGISTRATION Registration of the study at clinicalTrials.gov (NCT03129503).

Abstract
Posterior labral tears occur more often than imagined 25 years ago. Although such tears are generally identified in patients with posterior shoulder instability, the spectrum of labral tears in patients without instability creates a challenging diagnosis. Both physical examination and magnetic resonance imaging interpretation are difficult. Pathology encompassing posterior labral tears without instability notably reveals differences compared with throwers with posterior labral tears and patients with posterior instability. Recent research has identified 3 tear types: occult (type 1), incomplete (type 2), and complete (type 3). Attention to diagnosis deserves critical attention, in addition to tailoring of repair techniques to address the appropriate conditions in the shoulder. Even in patients without posterior instability and with ambiguous magnetic resonance imaging or magnetic resonance arthrography findings, posterior shoulder pain during daily activities or sports may indicate a posterior labral tear. Arthroscopic posterior labral repair without capsular plication provides good clinical outcomes and high rates of return to sport and labral healing.

Abstract
INTRODUCTION The area encompassing the long head of the biceps (LHB) can be represented as a rectangular parallelepiped. This geometric view can be likened to a box, the "biceps box", where the sides are the extrinsic structures and the LHB is the intrinsic structure. Since these structures are mobile in relation to each other, a dynamic "biceps box" model can modify assessments of the LHB, in its healthy or pathological state, and make the therapeutic approach to treating LHB lesions less arbitrary. MATERIAL AND METHOD In order to describe the different sides of the "biceps box", and to understand their possible physiological and pathological consequences, a literature review using PRISMA methodology was used. RESULTS The supraspinatus (SSP) has expansions on its anterior aspect that project anteriorly and cross the coracohumeral ligament (CHL). The most functionally important expansion is the fasciculus obliquus, which extends perpendicular to the axis of the tendon fibers of the SSP, divides the CHL into a deep and a superficial layer, and terminates on the superficial aspect of the subscapularis. The humeral insertion of the SSP may be binary, making a bridge over the LHB, with a posterior branch inserting on the greater tuberosity and an anterior branch on the lesser tuberosity. The superior glenohumeral ligament (SGHL) has a twisted course, downward and forward, and ends at the proximal opening of the bicipital groove with a flap on which the LHB rests. The bicipital pulley is not an independent structure but an arciform structure resulting from the fusion of several tissues. DISCUSSION The presence of structures linked together by common expansions in the 3 planes of space validates the relevance of a "biceps box" as a functional geometric model. The structure that acts as a crossroads through which all expansions pass is the CHL. An extrinsic SSP lesion can be compensated for by other "biceps box" structures, whereas an extrinsic SGHL lesion rarely exists without the presence of an intrinsic LHB lesion. The CHL constitutes a connective tissue crossed by a vasculonervous pedicle from the lateral pectoral nerve, which may explain some anterior shoulder pain attributed to the biceps. CONCLUSION The LHB can be likened to an intrinsic structure contained in a box whose sides are made up of different interconnected stabilizing structures defining the extrinsic structures. The concept of a dynamic "biceps box" allows LHB lesions to be accurately classified, separating extrinsic and intrinsic lesions, and thus potentially modifying therapeutic approaches to the LHB.

Abstract
PURPOSE To investigate the surgical outcomes of arthroscopic pull-out repair for medial meniscus root tear (MMRT) combined with the marrow stimulation procedures (MSP) for accompanying high-grade cartilage lesions. METHODS Patients who underwent arthroscopic pull-out repair for MMRT between 2010 and 2019 were retrospectively reviewed. Patients who had at least 3 years of follow-up were included and classified into two groups according to whether MSP (microfracture or microdrilling) were performed on cartilage lesions in the medial tibiofemoral joint (group 1, patients with International Cartilage Repair Society [ICRS] grade 0-3a lesions and did not undergo MSP; group 2, patients with ICRS grade 3b-3d lesions and underwent MSP). Comparative analyses, including non-inferiority trials, were conducted between groups for subjective and objective outcomes. In addition, group 2 was further divided into two subgroups according to cartilage lesion size and compared with group 1 (group S, ≤ 2.0 cm2; group L, > 2.0 cm2). RESULTS A total of 94 patients were included (group 1, 68 patients; group 2, 26 patients). There were no significant differences in clinical scores at postoperative 3 years and final follow-up between groups 1 and 2, but group 2 failed to satisfy the non-inferiority criteria compared to group 1 overall. In objective outcomes, group 2 did not meet the non-inferiority criteria for the rate of osteoarthritis progression compared to group 1, and it also showed a significantly higher proportion of high-grade osteoarthritis at final follow-up (P = 0.044) and a higher degree of osteoarthritis progression than group 1 (P = 0.03 for pre- to postoperative 3 years, and P = 0.006 for pre- to final follow-up). In additional evaluations comparing the subgroups of group 2 and group 1, group S showed relatively favourable results compared to group L in objective outcomes at final follow-up. CONCLUSION Patients who underwent arthroscopic pull-out repair for MMRT combined with MSP for accompanying high-grade cartilage lesions showed suboptimal outcomes compared to those with no or low-grade lesions at mid-term follow-up. High-grade cartilage lesions ≤ 2.0 cm2 may be candidates for the surgical repair of MMRT if MSP are performed, but those with larger lesions may require alternative treatment strategies.

Abstract
INTRODUCTION Inter-observer arthroscopic assessments of the Long head of the Biceps tendon (LHB) injuries, in the absence of predefined instructions, are poorly reproducible. There are several types of LHB injuries, of varying severity, which can make its intraoperative analysis subjective. HYPOTHESIS The application of a precise arthroscopic exploration protocol, particularly dynamic, associated with an equally precise analysis of the possible tendon lesions, intrinsic or extrinsic, makes it possible to obtain a reproducible analysis of the lesions of the LHB and aid decision-making around its conservation or its resection, in distal supraspinatus tendon ruptures. MATERIAL AND METHODS This was a prospective, multicenter study including 371 patients with a stage 1 rupture of the supraspinatus tendon, in accordance with the Patte classification. An exploration protocol with intraoperative video recording of the articular portion of the biceps was systematically performed by the operators. It included static intra-articular and extra-articular observation of the LHB, as well as a dynamic intra-articular hook test with mobilization in internal and external rotation, and in anterior elevation. An analysis of the lesion status of the LHB was then made by the principal operator (Op), after defining the various possible lesions: intrinsic or extrinsic. This initial diagnostic assessment was then compared with the analysis made by two independent observers (Obs1, Obs2) based on a replay of the recorded videos. The reliability of agreement was then measured using Cohen's Kappa coefficient (K) and Fleiss' kappa. RESULTS Two hundred and fifty-seven videos were analyzable. The level of agreement between the two independent observers was strong (K=0.63) for applying the diagnosis of a healthy or pathological biceps. The agreement between the independent observers and the operator was weaker (respectively K Op-Obs1=0.51 - moderate and K Op-Obs2=0.39 - poor). CONCLUSION The application of a precise protocol for the exploration of the LHB, associated with a previously defined lesion classification, makes it possible to obtain a high rate of agreement for the arthroscopic diagnostic analysis of the LHB. However, arthroscopy cannot be used as the only criterion for deciding which procedure to perform on the LHB. Other clinical and para-clinical factors must be taken into consideration.

Abstract
PURPOSE This study evaluated the differences in meniscal sizes and occupancy between symptomatic and asymptomatic patients diagnosed with discoid lateral meniscus (DLM) using magnetic resonance imaging (MRI) to understand how these variations relate to the presence of symptoms and the patients' age. METHODS A retrospective review of 98 patients with DLM was conducted, excluding those with meniscal displacement. Both the width and extrusion of DLM and the percentage of the meniscus to the tibia were measured using mid-coronal and mid-sagittal MRI and compared between symptomatic and asymptomatic DLM groups. The relationships among each parameter, meniscal size, and patient age were evaluated. Symptomatic cases were divided into those with and without horizontal tears on MRI to compare the differences in meniscal morphology. RESULTS A total of 92 knees from 74 patients were included. Sixty-one knees required surgical intervention for symptomatic DLM, while 31 were asymptomatic and included the contralateral side of symptomatic knees. The symptomatic group exhibited larger morphological variations than the asymptomatic group. Moreover, the sagittal meniscal ratio reduced with age in the asymptomatic group (r = - 0.54, p = 0.002) but remained constant in the symptomatic group. The symptomatic cases with horizontal tears demonstrated larger meniscal dimensions and smaller posterior capsule distances than those without tears. CONCLUSION Symptomatic patients with DLM had larger knee morphological changes than asymptomatic ones. Age affected the meniscal occupancy in the sagittal plane only in asymptomatic patients.

Abstract
BACKGROUND Injuries to the biceps reflection pulley lead to instability of the long head of the biceps tendon (LHBT). However, conventional magnetic resonance (MR) imaging (MRI) has low diagnostic accuracy for LHBT and pulley lesions. Here, we investigated the usefulness of novel biceps-radial MRI for evaluating LHBT and pulley lesions. METHODS Biceps-radial MR images of 84 patients (84 shoulders) were prospectively analyzed. The biceps-radial MRI protocol includes sequences acquired in radial planes perpendicular to the LHBT in the shoulder joint. All patients underwent shoulder arthroscopy, and the intraoperative LHBT and pulley lesion findings were compared to the preoperative evaluations. The diagnostic accuracies of the biceps-radial MR images and conventional MR images were determined. RESULTS A normal LHBT was observed in 30 (31.6%) patients, partial tears in 43 (52.6%), and complete tears in 11 (15.8%). Normal LHBT stability was present in 54 (61.4%) patients, subluxation in 24 (31.6%), and dislocation in 6 (7.0%). The biceps-radial MR (kappa coefficient: 0.94) and conventional MR (kappa coefficient: 0.68) images accurately identified LHBT tears. The biceps-radial MR images excellently agreed with the arthroscopic findings (kappa coefficient: 0.91), whereas the conventional MR images poorly agreed (kappa coefficient: 0.17) regarding LHBT instability. A normal medial wall of the pulley was observed in 26 (31.0%) patients, partial tears in 30 (35.7%), and complete tears in 28 (33.3%). A normal lateral wall of the pulley was observed in 30 (35.7%) patients, partial tears in 21 (25.0%), and complete tears in 33 (39.3%). The biceps-radial MR images excellently agreed with the arthroscopic findings (kappa coefficient: 0.89), whereas the conventional MR images moderately agreed (kappa coefficient: 0.50) regarding medial pulley lesions. The biceps-radial MR images excellently agreed with the arthroscopic findings (kappa coefficient: 0.95) and the conventional MR images moderately agreed (kappa coefficient: 0.56) regarding lateral pulley lesions. CONCLUSION Biceps-radial MRI allows for tracking of the LHBT and pulley from the supraglenoid tuberosity to the bicipital groove in the glenohumeral joint and accurate evaluations of LHBT and pulley lesions.

Abstract
BACKGROUND Unlike the adult meniscus, the fetal meniscus possesses robust healing capacity. The dense and stiff matrix of the adult meniscus provides a biophysical barrier for cell migration, which is not present in the fetal meniscus. Inspired by developmental characteristics, modifying the matrix of the adult meniscus into a fetal-like, loose and soft microenvironment holds opportunity to facilitate repair, especially in the avascular zone. HYPOTHESIS Modifying the dense and stiff matrix of the adult meniscus into a fetal-like, loose and soft microenvironment could enhance cell migration to the tear interface and subsequent robust healing capacity. STUDY DESIGN Controlled laboratory study. METHODS Fresh porcine menisci were treated with hyaluronidase or collagenase. The density and arrangement of collagen fibers were assessed. The degradation of proteoglycans and collagen was evaluated histologically. Cell migration within the meniscus or the infiltration of exogenous cells into the meniscus was examined. Dendritic silica nanoparticles with relatively large pores were used to encapsulate hyaluronidase for rapid release. Mesoporous silica nanoparticles with relatively small pores were used to encapsulate transforming growth factor-beta 3 (TGF-β3) for slow release. A total of 24 mature male rabbits were included. A longitudinal vertical tear (0.5 cm in length) was prepared in the avascular zone of the medial meniscus. The tear was repaired with suture, repaired with suture in addition to blank silica nanoparticles, or repaired with suture in addition to silica nanoparticles releasing hyaluronidase and TGF-β3. Animals were sacrificed at 12 months postoperatively. Meniscal repair was evaluated macroscopically and histologically. RESULTS The gaps between collagen bundles increased after hyaluronidase treatment, while collagenase treatment resulted in collagen disruption. Proteoglycans degraded after hyaluronidase treatment in a dose-dependent manner, but collagen integrity was maintained. Hyaluronidase treatment enhanced the migration and infiltration of cells within meniscal tissue. Last, the application of fibrin gel and the delivery system of silica nanoparticles encapsulating hyaluronidase and TGF-β3 enhanced meniscal repair responses in an orthotopic longitudinal vertical tear model. CONCLUSION The gradient release of hyaluronidase and TGF-β3 removed biophysical barriers for cell migration, creating a fetal-like, loose and soft microenvironment, and enhanced the fibrochondrogenic phenotype of reparative cells, facilitating the synthesis of matrix and tissue integration. CLINICAL RELEVANCE Modifying the adult matrix into a fetal-like, loose and soft microenvironment via the local gradient release of hyaluronidase and TGF-β3 enhanced the healing capacity of the meniscus.

Abstract
BACKGROUND In children, the incidence of anterior cruciate ligament (ACL) ruptures and reconstructions has significantly risen. Unfortunately, re-rupture rates following surgery are substantially higher in children than adults. Previous research suggests that smaller graft diameters are predictive of re-rupture. OBJECTIVE This study aimed to investigate the growth progression of the ACL bone graft, specifically in terms of width and length, within the intra-articular portion and tunnels, using successive magnetic resonance imaging (MRI) scans. The hypothesis was that the ACL grafts would undergo thinning during growth. MATERIALS AND METHODS The cohort comprised 100 patients who underwent ACL reconstruction. Among them, 37 patients with significant residual growth were selected for analysis. Of these, 4 patients experienced graft rupture, 5 had "over-the-top" techniques, 12 had missing MRI scans and 5 were lost to follow-up. Each included patient underwent two MRI scans; the analyses of which were conducted in a double-masked manner. RESULTS A total of 13 knees (and patients) were analyzed, with a mean ± SD (range) delay of residual growth between the two MRI scans of 3.3 + / - 1.4 (1.2-5.2) years. The graft exhibited elongation, thinning and eventual integration with the surrounding bone in the tunnels. Within the intra-articular portion, the mean [95% CI] increase in graft size between the two MRI scans was 30.8% in length and 14.8% in width. The width/length ratio in the intra-articular part was 20.4% on the first MRI and 20.8% on the second MRI. Since this difference in the ratio (+ 0.4%) was not statistically significant (P=0.425), our results indicate that the grafts remained stable in terms of proportions without thinning or thickening. Therefore, the initial hypothesis was validated for the tunnel portion but not the intra-articular portion of the grafts. CONCLUSION In children with open physes, ACL grafts demonstrate smooth growth progression in all dimensions. However, this finding does not fully explain the high rate of re-rupture observed in children. Further research is needed to elucidate the underlying factors contributing to re-rupture in this population.

Abstract
Rathke cleft cysts are common cystic pituitary lesions seen on MR imaging. A subset of Rathke cleft cysts can rupture within the sella and are uncommon. The imaging appearance of a ruptured Rathke cleft cyst has been previously described with nonspecific imaging findings. We present 7 cases of ruptured Rathke cleft cysts and basisphenoid bone marrow enhancement below the sella that could be used to potentially distinguish a ruptured Rathke cleft cyst from other cystic lesions.

Abstract
Miranda et al. reported a correlation between the significance of injuries to osseous, chondral, tendon, and ligamentous tissues in participants with low-grade versus high-grade acute ankle sprains. They demonstrated that participants with high-grade ankle sprains presented with shorter calcaneonavicular distances and increased rates of structural abnormalities compared to those with low-grade sprains. Special attention should be paid to acute ankle sprains in emergency settings to avoid failure in detecting severe injuries that could lead to chronic pain, impairment, or instability. Participants presenting acute ankle sprains (<15 days) were divided into low-grade versus high-grade sprain,according to the presence of a complete tear in at least one component of lateral ligament complex. High-grade ankle sprains group presented increased rates of medial malleolus bone bruise, deltoid ligament tears,extensor retinaculum lesions, and articular effusion. The calcaneonavicular distance was statistically shorter in patients with high-grade sprains (median, 3.0mm) when compared to those with low-grade sprains (median, 4.0mm) Objective: To correlate the significance of osseous, chondral, tendon, and ligamentous injuries with anatomical variations in low-grade versus high-grade acute ankle sprains. METHODS We retrospectively identified the magnetic resonance imaging findings of acute ankle sprains (<15 days). Participants with a history of previous sprains, arthritis, tumors, infections, or inflammatory conditions were excluded. Images were independently evaluated by two musculoskeletal radiologists and assessed for osseous, chondral, tendon, and ligamentous injuries and anatomical variations. Participants were divided into low-grade versus high-grade sprain groups, according to the presence of a complete tear in at least one component of the lateral ligament complex. RESULTS The final study group comprised 100 magnetic resonance images (mean age, 36 years), the majority of males (54%), the right ankle (52%), and a mean sprain duration of 5 days. Participants with high-grade sprains presented with increased rates of medial malleolus edema (p<0.001), moderate and large articular effusions (p=0.041), and shorter calcaneonavicular distance (p=0.008). Complete tears of the anterior talofibular ligament and calcaneofibular ligaments were observed in 100% and 51.2% of the participants in the High-Grade Group, respectively. The deltoid ligament complex was partially torn in this group (55.8% versus 8.8%, p<0.001). Extensor tendon retinaculum lesions occurred significantly more frequently in this group (41.9%) compared to the overall study population (23%) (p<0.001). CONCLUSION Participants with high-grade ankle sprains presented with shorter calcaneonavicular distances and increased rates of medial malleolus edema, deltoid complex partial tears, extensor retinaculum lesions, and articular effusion.

Abstract
Background Rotator cuff injury occurs over tendons that insert into the humeral tuberosity. Ultrasonography detects the size and extent of tendon tears. Its sensitivity and specificity range from 91-100% and 85-86%, respectively. It has been shown that a trained orthopedic surgeon can perform shoulder ultrasonography for the accurate diagnosis of rotator cuff pathology. Objective To determine the concordance between ultrasound-arthroscopy of the shoulder in rotator cuff injuries at the Unidad Médica Atención Ambulatoria No. 55 (Ambulatory Care Unit No. 55) in León, Guanajuato, Mexico. Material and methods Experimental study of a sample of 37 patients with a diagnosis of rotator cuff injury, in whom preoperative ultrasound and later shoulder arthroscopy of the same side were performed. The data were subjected to concordance with Cohen's Kappa Index. Results There were 37 patients in whom we identified an overall concordance of 81%. Cohen's Kappa index was 0.76, considered a good concordance. Out of the 7 patients without correlation, in 1 patient the ultrasound showed partial rupture and by arthroscopy showed complete rupture of the supraspinatus. In 2 patients ultrasonography showed complete rotator cuff tear; during arthroscopy, both showed massive rotator cuff tear. Conclusions Preoperative shoulder ultrasonography performed by traumatology presents a good concordance in the diagnosis of rotator cuff tears confirmed by arthroscopy.

Abstract
PURPOSE False penile fractures (FPF) represent a rare sexual emergency characterized by blunt trauma of penis in the absence of albuginea's injury, with or without lesion of dorsal penile vein. Their presentation is often indistinguishable from true penile fractures (TPF). This overlapping of clinical presentation, and lack of knowledge about FPF, can lead surgeons often to proceed directly to surgical exploration without further examinations. The aim of this study was to define a typical presentation of false penile fractures (FPF) emergency, identifying in absence of "snap" sound, slow detumescence, penile shaft ecchymosis, and penile deviation main clinical signs. METHODS We performed a systematic review and meta-analysis based on Medline, Scopus and Cochrane following a protocol designed a priori, to define sensitivity of "snap" sound absence, slow detumescence and penile deviation. RESULTS Based on the literature search of 93 articles, 15 were included (73 patients). All patients referred pain, most of them during coitus (n = 57; 78%). Detumescence occurred in 37/73 (51%), and all patients described detumescence occurrence as "slow". The results show that single anamnestic item have a high-moderate sensibility in the diagnosis of FPF, and the highest sensitive item was penile deviation (sensibility = 0.86). However, when more than one item is present, overall sensitivity increases greatly, closing to 100% (95% Confidence Interval 92-100). CONCLUSION Surgeons can consciously decide between additional exams, a conservative approach, and rapid intervention using these indicators to detect FPF. Our findings identified symptoms with excellent specificity for FPF diagnosis, giving clinicians more useful tools for making decisions.

Abstract
BACKGROUND An Achilles tendon rupture (ATR) is a frequent injury and results in the activation of tendon cells and collagen expression, but it is unknown to what extent turnover of the tendon matrix is altered before or after a rupture. PURPOSE/HYPOTHESIS The purpose of this study was to characterize tendon tissue turnover before and immediately after an acute rupture in patients. It was hypothesized that a rupture would result in pronounced collagen synthesis in the early phase (first 2 weeks) after the injury. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS The study included patients (N = 18) eligible for surgery after an ATR. At the time of inclusion, the patients ingested deuterium oxide (2H2O) orally, and on the day of surgery (within 14 days of the injury), they received a 3-hour flood-primed infusion of an 15N-proline tracer. During surgery, the patients had 1 biopsy specimen taken from the ruptured part of the Achilles tendon and 1 that was 3 to 5 cm proximal to the rupture as a control. The biopsy specimens were analyzed for carbon-14 (14C) levels in the tissue to calculate long-term turnover (years), incorporation of 2H-alanine (from 2H2O) into the tissue to calculate the fractional synthesis rate (FSR) of proteins in the short term (days), and incorporation of 15N-proline into the tissue to calculate the acute FSR (hours). RESULTS Both the rupture and the control samples showed consistently lower levels of 14C compared with the predicted level of 14C in a healthy tendon, which indicated increased tendon turnover in a fraction (48% newly synthesized) of the Achilles tendon already for a prolonged period before the rupture. Over the first days after the rupture, the synthesis rate for collagen was relatively constant, and the average synthesis rate on the day of surgery (2-14 days after the rupture) was 0.025% per hour, irrespective of the length of time after a rupture and the site of sampling (rupture vs control). No differences were found in the FSR between the rupture and control samples in the days after the rupture. CONCLUSION Higher than normal tissue turnover in the Achilles tendon before a rupture indicated that changes in the tendon tissue preceded the injury. In addition, we observed no increase in tendon collagen tissue turnover in the first 2 weeks after an ATR. This favors the view that an increase in the formation of new tendon collagen is not an immediate phenomenon during the regeneration of ruptured tendons in patients.

Abstract
INTRODUCTION the acromion is a small portion of the scapula that extends towards the anterior region from the spine of the scapula. Traditionally, the acromion is classified by the shape of its inferior surface in a sagittal plane. Acromial morphology has been found to be related to rotator cuff injury. OBJECTIVE to determine the association between the type of acromion with a higher incidence of rotator cuff rupture. Study population: patients who come to the Traumatology and Orthopedics Service of a third level hospital at Monterrey, Mexico, due to a painful shoulder and who have undergone a simple magnetic resonance of the shoulder. MATERIAL AND METHODS a cross-sectional, retrospective and descriptive study was carried out, in which 273 magnetic resonance studies were reviewed in patients who met the inclusion criteria. The type of acromion was reported according to the morphological classification in type I to IV and the state of the rotator cuff: without rupture, partial rupture or complete rupture, making a comparison between right and left shoulder. RESULTS in this study we found a value of p = 0.473 which concludes that there is no relation between the type of acromion and the injury of the rotator cuff. CONCLUSION in the present study, unlike what has been published in the literature, it was found that type II acromion was the one that was associated in most cases with a rotator cuff tear.

Abstract
BACKGROUND Atrophy of the rotator cuff is a negative prognostic indicator after rotator cuff repair. Although full-thickness rotator cuff tears accompanied by tendon retraction are commonly associated with decreased muscle cross-sectional area (CSA) on magnetic resonance imaging (MRI), it is unclear whether this is accompanied by histologic atrophy of rotator cuff myofibers. PURPOSE To evaluate the effect of supraspinatus tendon retraction and myofiber size on supraspinatus atrophy on MRI. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Supraspinatus muscle biopsy specimens were obtained from consecutive patients undergoing arthroscopic shoulder surgery. Rotator cuff tears were classified according to size. Preoperative MRI was used to measure tendon retraction and CSA of the supraspinatus muscle in the Y-shaped view. The occupation ratio of the supraspinatus was calculated by dividing the supraspinatus CSA by the supraspinatus fossa CSA. Muscle biopsy specimens were examined using laminin to quantify myofiber CSA. The association between supraspinatus tear size and measures of histologic and MRI muscle atrophy were compared using standard statistical tests. Multivariable logistic regression analysis was used to identify independent predictors of muscle atrophy on MRI. RESULTS A total of 38 patients were included: 8 with no tear, 14 with a partial-thickness tear, and 16 with a full-thickness tear. Increasing tear size was associated with greater distance of tendon retraction (P < .001), smaller mean histologic myofiber size (P = .004), lower mean supraspinatus CSA on MRI (P < .001), and lower occupation ratio: 0.73 (control), 0.66 (partial tear), 0.53 (small to medium full-thickness tear), and 0.38 (large to massive full-thickness) (P < .001). On Pearson correlation analysis, tendon retraction demonstrated strong correlation with occupation ratio (-0.725; P < .001) and weak correlation with myofiber size (-0.437; P = .006), while occupation ratio showed moderate correlation with myofiber size (0.593; P < .001). Multivariable linear regression analysis demonstrated that increasing tendon retraction (P < .001), age (P = .034), and smaller histologic myofiber CSA (P = .047) were independently associated with greater supraspinatus atrophy on MRI. CONCLUSION Supraspinatus muscle atrophy appreciated on MRI is independently associated with patient age, tendon retraction, and atrophy of the supraspinatus myofibers at the histologic level.

Abstract
After Achilles tendon tenorraphy, tendon tissue undergoes a long period of biological healing. During this period, tissue turnover shows heterogeneity between its peripheral and central regions. This case report concerns the description of the tendon healing process of an athlete who underwent an Achilles tendon tenorraphy. As the reparative processes progressed, magnetic resonance imaging (MRI) showed centralization of the hyperintensity area and the tendon assumed a doughnut-like appearance. At the same time, ultrasound (US) assessment showed a progressive reorganization of the tendon fibrillar structure. Therefore, for the athlete, MRI and US assessment together represent a useful tool for the decision-making process after Achilles tendon tenorraphy.

Abstract
OBJECTIVES To evaluate extensor carpi ulnaris (ECU) tendon pathology and ulnar styloid process bone marrow edema (BME) as diagnostic MRI markers for peripheral triangular fibrocartilage complex (TFCC) tears. METHODS One hundred thirty-three patients (age range 21-75, 68 females) with wrist 1.5-T MRI and arthroscopy were included in this retrospective case-control study. The presence of TFCC tears (no tear, central perforation, or peripheral tear), ECU pathology (tenosynovitis, tendinosis, tear or subluxation), and BME at the ulnar styloid process were determined on MRI and correlated with arthroscopy. Cross-tabulation with chi-square tests, binary logistic regression with odds ratios (OR), and sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were used to describe diagnostic efficacy. RESULTS On arthroscopy, 46 cases with no TFCC tear, 34 cases with central perforations, and 53 cases with peripheral TFCC tears were identified. ECU pathology was seen in 19.6% (9/46) of patients with no TFCC tears, in 11.8% (4/34) with central perforations and in 84.9% (45/53) with peripheral TFCC tears (p < 0.001); the respective numbers for BME were 21.7% (10/46), 23.5% (8/34), and 88.7% (47/53) (p < 0.001). Binary regression analysis showed additional value from ECU pathology and BME in predicting peripheral TFCC tears. The combined approach with direct MRI evaluation and both ECU pathology and BME yielded a 100% positive predictive value for peripheral TFCC tear as compared to 89% with direct evaluation alone. CONCLUSIONS ECU pathology and ulnar styloid BME are highly associated with peripheral TFCC tears and can be used as secondary signs to diagnose tears. KEY POINTS • ECU pathology and ulnar styloid BME are highly associated with peripheral TFCC tears and can be used as secondary signs to confirm the presence of TFCC tears. • If there is a peripheral TFCC tear on direct MRI evaluation and in addition both ECU pathology and BME on MRI, the positive predictive value is 100% that there will be a tear on arthroscopy compared to 89% with direct evaluation alone. • If there is no peripheral TFCC tear on direct evaluation and neither ECU pathology nor BME on MRI, the negative predictive value is 98% that there will be no tear on arthroscopy compared to 94% with direct evaluation alone.

Abstract
OBJECTIVES To determine the relationship between the severity of the tear gap resulting from medial meniscus posterior root (MMPR) tear and medial meniscal extrusion, cartilage, bone, and ligament lesions on MRI. METHODS A total of 133 patients with MMPR tear were retrospectively evaluated. The patients were divided into two groups according to the tear gap width as minor (≤ 4 mm) and widely (4 mm<) displaced. Medial meniscal extrusion and medial compartmental chondromalacia, bone and ligament lesions were analyzed. RESULTS There were 61 patients (56 women and 5 men) in the minor displaced group (mean age: 56.3 years, range: 29-82 years) and 72 patients (59 women, 13 men) in the widely displaced group (mean age: 53.2 years, range: 20-86 years). There was no significant difference in terms of age and sex (p = 0.31 and p = 0.09, respectively). The mean absolute extrusion was 3.51 mm (range: 1.5-5 mm) in the minor displaced group and 4.52 mm (range: 2.4-7.2 mm) in the widely displaced group (p < 0.001). High-grade medial femoral condylar chondromalacia was more common in the widely displaced group (p = 0.002). Osteophyte, bone marrow edema, and subchondral cyst in the medial compartment, and ligament injury were higher in the widely displaced group, but were not statistically significant (p > 0.05). CONCLUSION The amount of medial meniscal extrusion and the prevalence of high-grade medial femoral condylar chondromalacia were found to be significantly more in patients with wider tear gap. Determining the amount of tear gap in the evaluation of root ligament tears on MRI is important to predict knee joint internal derangement.

Abstract
Deep learning is an advanced machine learning approach used in diverse areas such as image analysis, bioinformatics, and natural language processing. In the current study, using only one knee magnetic resonance image of each patient, we attempted to develop a convolutional neural network (CNN) to diagnose anterior cruciate ligament (ACL) tear. We retrospectively recruited 164 patients who had knee injury and underwent knee magnetic resonance imaging evaluation. Of 164 patients, 83 patients' ACLs were torn (20 patients, partial tear; 63 patients, complete tear), whereas 81 patients' ACLs were intact. We used a CNN algorithm. Of the included subjects, 79% were assigned randomly to the training set and the remaining 21% were assigned to the test set to measure the model performance. The area under the curve was 0.941 (95% CI, 0.862-1.000) for the classification of intact and tears of the ACL. We demonstrated that a CNN model trained using one knee magnetic resonance image of each patient could be helpful in diagnosing ACL tear.

Abstract
Predisposition to anterior cruciate ligament (ACL) rupture is multi-factorial, with variation in the genome considered a key intrinsic risk factor. Most implicated loci have been identified from candidate gene-based approach using case-control association settings. Here, we leverage a hypothesis-free whole genome sequencing in two two unrelated families (Family A and B) each with twins with a history of recurrent ACL ruptures acquired playing rugby as their primary sport, aimed to elucidate biologically relevant function-altering variants and genetic modifiers in ACL rupture. Family A monozygotic twin males (Twin 1 and Twin 2) both sustained two unilateral non-contact ACL ruptures of the right limb while playing club level touch rugby. Their male sibling sustained a bilateral non-contact ACL rupture while playing rugby union was also recruited. The father had sustained a unilateral non-contact ACL rupture on the right limb while playing professional amateur level football and mother who had participated in dancing for over 10 years at a social level, with no previous ligament or tendon injuries were both recruited. Family B monozygotic twin males (Twin 3 and Twin 4) were recruited with Twin 3 who had sustained a unilateral non-contact ACL rupture of the right limb and Twin 4 sustained three non-contact ACL ruptures (two in right limb and one in left limb), both while playing provincial level rugby union. Their female sibling participated in karate and swimming activities; and mother in hockey (4 years) horse riding (15 years) and swimming, had both reported no previous history of ligament or tendon injury. Variants with potential deleterious, loss-of-function and pathogenic effects were prioritised. Identity by descent, molecular dynamic simulation and functional partner analyses were conducted. We identified, in all nine affected individuals, including twin sets, non-synonymous SNPs in three genes: COL12A1 and CATSPER2, and KCNJ12 that are commonly enriched for deleterious, loss-of-function mutations, and their dysfunctions are known to be involved in the development of chronic pain, and represent key therapeutic targets. Notably, using Identity By Decent (IBD) analyses a long shared identical sequence interval which included the LINC01250 gene, around the telomeric region of chromosome 2p25.3, was common between affected twins in both families, and an affected brother'. Overall gene sets were enriched in pathways relevant to ACL pathophysiology, including complement/coagulation cascades (p = 3.0e-7), purine metabolism (p = 6.0e-7) and mismatch repair (p = 6.9e-5) pathways. Highlighted, is that this study fills an important gap in knowledge by using a WGS approach, focusing on potential deleterious variants in two unrelated families with a historical record of ACL rupture; and providing new insights into the pathophysiology of ACL, by identifying gene sets that contribute to variability in ACL risk.

Abstract
OBJECTIVES Cuffed endotracheal intubation and stent implantation were employed to simulate two types of benign airway stenosis and further to analysis the different features between them from trachecscopic characteristics, gross anatomy to histopathological changes. In addition, our study explored the therapeutic effect of mitomycin C at different concentrations on granulation tissue caused by stent implantation in order to provide a new therapeutic strategy for clinical treatment of benign airway stenosis. METHODS Twelve beagle dogs were randomly divided into four groups, with three dogs in each group. Group A: Three beagle dogs were intubated through oral trachea after general anesthesia and cuff pressure maintained at 200 mmHg for 24 h. Group B, Group C and Group D: endotracheal coated self-expanding metal stents were placed after general anesthesia under the guidance of bronchoscope. On the Day7 after stent implantation, Group B, as control group, was injected phosphate buffer solution of 1 ml into granulation tissue at the end of stent; Group C was injected mitomycin C of 1 ml at 0.4 mg/ml and Group D was injected mitomycin C of 1 ml at 0.8 mg/ml into granulation tissue at the end of metal airway stent respectively, the same method as Group B. Bronchoscopy was used to observe tracheal lumen on the seventh day, fourteenth day and twenty-first day after modeling and pathological changes were examined on twenty-first day. RESULTS Two models of benign airway stenosis can be established by cuffed endotracheal intubation and stent implantation. There was tracheal rupture in the trachea cartiage ring in the cuffed endotracheal intubation group, but was't in stent implantation group. Histopathological characteristics were different between cuffed endotracheal intubation and stent implantation groups. In stent placement groups, we found that the stenosis degree of mitomycin C at 0.4 mg/ml was approximately 19%-32%, mitomycin C at 0.8 mg/ml was approximately 16%-21% and the control group was approximately 36%-47%. CONCLUSION The two models of canine benign tracheal stenosis induced by cuffed endotracheal intubation and stent implantation are relatively simple, reliable and reproducible and have different characteristics. Mitomycin C could inhibit proliferation of granulation tissue and attenuate the degree of airway stenosis caused by stent implantation.

Abstract
PURPOSE To examine healing adaptations over 17 weeks post Achilles tendon (AT) rupture in the injured region (IR) compared to an uninjured region (UIR) of the AT. METHODS Twenty-four rats were subjected to a complete right-sided AT rupture, while the left side served as a control. ATs were harvested at 1, 2, 8 and 17 weeks post-rupture and stained with antibodies specific to Collagen type I (Col I) and II (Col II) as well as Alcian Blue and Picrosirius Red staining techniques. Histopathological changes, proteoglycan content, collagen alignment and immunoexpression were assessed. RESULTS Both regions examined, IR and UIR, exhibited over weeks 1-17 similar healing adaptations of increasing collagen alignment, decreasing Col I immunoexpression, as well as increasing proteoglycan content and Col II occurrence. Increased proteoglycan content was found already at week 2 in the UIR, while it first increased at week 8 in the IR. The area positive to Col II was increased compared to controls at week 8 in the UIR, whereas it first raised at week 17 in the IR. Collagen disorganization successively declined to reach control levels at week 17 in the UIR, but was still higher in the IR. CONCLUSION This study demonstrated that uninjured areas of the AT remote from the rupture site also undergo pronounced remodeling, although with time-span differences relative to injured AT portions. These changes including the pathologic heterotopic mineralization and chondrogenic differentiation observed in both regions may have implications in the choice of rehabilitation regimes in order to prevent secondary rupture.

Abstract
ABSTRACT Isolated right atrial rupture after nonpenetrating blunt chest trauma is rare, and very few cases have been reported in the literature. Isolated right atrial rupture is a diagnostic challenge in these patients, who are mostly victims of motor vehicle collisions. The clinical presentation is heterogeneous and can vary depending on rupture location and size. The anatomical sites mostly involved are the appendage and the free wall followed by the superior and inferior vena cava junctions. The present case study shows a fatal isolated rupture of the right atrial appendage in a victim of a motor vehicle collision. At the emergency room, a computed tomography scan revealed a severe pericardial blood effusion, and pericardiocentesis was promptly performed. Unfortunately, the patient suddenly worsened just before cardiac surgery. Autopsy findings showed a cardiac tamponade due to a linear laceration 1.8 cm in length on the right atrial appendage. No other relevant injuries were observed. A prompt diagnosis of isolated right atrial rupture can be crucial for victims of blunt chest trauma with unexplained hypotension or hemodynamic instability to improve their chances of survival. Medicolegal issues can be raised mainly related to delayed diagnosis. Once a cardiac rupture is suspected, the injury repair is essential to achieve the best outcome.

Abstract
INTRODUCTION Rupture of the radial collateral ligament (RCL) of the index metacarpophalangeal (MCP) joint is mostly related to acute local mechanical causes, which severely affect the stability of the MCP joint. However, few cases of chronic bilateral job-related RCL injury have been reported in the literature. There is no consensus on the knowledge of the disease to date. Here, we present an extremely rare case of chronic bilateral RCL injury. PATIENT CONCERNS A 58-year-old female shoemaker presented with chief complaints of swelling and pain in the radial aspect of the MCP joint of bilateral index fingers since 2 years. There was no history of acute RCL injury. The persistent pain was aggravated while gripping, pulling, buttoning, and twisting. DIAGNOSIS Based on the combination of physical examination, X-ray, and ultrasonic and magnetic resonance imaging, the patient was diagnosed with bilateral tear of the RCLs and joint dislocation of the index MCP joint. Eventually, intra-operative findings confirmed the diagnosis. INTERVENTION The patient underwent bilateral index MCP joint fusion followed by immobilization for 6 weeks. Functional therapy was started after immobilization. OUTCOMES The patient's chief complaints were significantly alleviated after the operation. At the 12-month follow-up, the patient returned to a full level of activity as a shoemaker without any complications. CONCLUSION Compared to acute RCL rupture of the index MCP joint, occupation may play an important role in the diagnosis of chronic RCL rupture of the index MCP joint. Our report will provide more diagnostic and treatment experience to deal with this type of injury.

Abstract
Cardiac ischemia leads to the loss of myocardial tissue and the activation of a repair process that culminates in the formation of a scar whose structural characteristics dictate propensity to favorable healing or detrimental cardiac wall rupture. To elucidate the cellular processes underlying scar formation, here we perform unbiased single-cell mRNA sequencing of interstitial cells isolated from infarcted mouse hearts carrying a genetic tracer that labels epicardial-derived cells. Sixteen interstitial cell clusters are revealed, five of which were of epicardial origin. Focusing on stromal cells, we define 11 sub-clusters, including diverse cell states of epicardial- and endocardial-derived fibroblasts. Comparing transcript profiles from post-infarction hearts in C57BL/6J and 129S1/SvImJ inbred mice, which displays a marked divergence in the frequency of cardiac rupture, uncovers an early increase in activated myofibroblasts, enhanced collagen deposition, and persistent acute phase response in 129S1/SvImJ mouse hearts, defining a crucial time window of pathological remodeling that predicts disease outcome.

Abstract
BACKGROUND Numerous quantitatively based studies measuring the accuracy of MRI and MRA for the diagnosis of rotator cuff tears remain inconclusive. In order to compare the accuracy of MRI with MRA in detection of rotator cuff tears a meta-analysis was performed systematically. METHODS PubMed/Medline and Embase were utilized to retrieve articles comparing the diagnostic performance of MRI and MRA for use in detecting rotator cuff tears. After screening and diluting out the articles that met inclusion criteria to be used for statistical analysis the pooled evaluation indexes including sensitivity and specificity as well as hierarchical summary receiver operating characteristic (HSROC) curves with 95% confidence interval (CI) were calculated. RESULTS Screening determined that 12 studies involving a total of 1030 patients and 1032 shoulders were deemed viable for inclusion in the meta-analysis. The results of the analysis showed that MRA has a higher sensitivity and specificity than MRI for the detection of any tear; similar results were observed in the detection of full-thickness tears. However, for the detection of partial-thickness tear, MRI has similar performance with MRA. CONCLUSION MRI is recommended to be a first-choice imaging modality for the detection of rotator cuff tears. Although MRA have a higher sensitivity and specificity, it cannot replace MRI after the comprehensive consideration of accuracy and practicality.

Abstract
Current methods for tendon rupture repair suffer from two main drawbacks: insufficient strength and adhesion formation, which lead to rerupture and impaired gliding. A novel polymer tube may help to overcome these problems by allowing growth factor delivery to the wound site and adhesion reduction, and by acting as a physical barrier to the surrounding tissue. In this study, we used a bilayered DegraPol® tube to deliver PDGF-BB to the wound site in a full-transection rabbit Achilles tendon model. We then performed histological and immunohistochemical analysis at 3 weeks postoperation. Sustained delivery of PDGF-BB to the healing Achilles tendon led to a significantly more homogenous cell distribution within the healing tissue. Lower cell densities next to the implant material were determined for +PDGF-BB samples compared to -PDGF-BB. PDGF-BB application increased proteoglycan content and reduced alpha-SMA+ areas, clusters of different sizes, mainly vessels. Finally, PDGF-BB reduced collagens I and III in the extracellular matrix. The sustained delivery of PDGF-BB via an electrospun DegraPol® tube accelerated tendon wound healing by causing a more uniform cell distribution with higher proteoglycan content and less fibrotic tissue. Moreover, the application of this growth factor reduced collagen III and alpha-SMA, indicating a faster and less fibrotic tendon healing.

Abstract
PURPOSE To compare the clinical, imaging, and arthroscopic characteristics of the torn discoid lateral meniscus (TDLM) in patients greater than 40 years of age with matched controls. METHODS One hundred and ninety-four older patients (211 knees) who underwent arthroscopic surgery for a TDLM were consecutively recruited (Group 1). Another 211 age- and sex-matched controls with a torn semilunar lateral meniscus were included in this study (Group 2). Statistical analyses were used to determine the differences in the clinical, imaging, and arthroscopic characteristics between the two groups. RESULTS In our series, more severe medial meniscal extrusion on magnetic resonance imaging was present in Group 1 than in Group 2 and more serious osteoarthritic changes were observed in both the medial and lateral compartments in Group 1. Under the same conditions, chondral lesions in the knee were more serious in Group 1 than in Group 2 when patients were subgrouped according to the presence of a horizontal tear or complex tear. CONCLUSIONS In the present study, older patients with a torn discoid lateral meniscus exhibited greater and more severe medial meniscal extrusion and more serious osteoarthritis. Therefore, knees with a discoid lateral meniscus displaying medial meniscal extrusion should be monitored carefully with long-term follow-up, because a medial meniscal extrusion may increase the risk of progression to degenerative osteoarthritis of the medial compartment. Regarding the clinical relevance, these findings will be helpful in further revealing that a torn discoid lateral meniscus may affect not only the cartilage in the lateral compartment but also the cartilage in the medial compartment and medial meniscal extrusion.

Abstract
Tendinopathies are common chronic injuries that occur when damage accumulation caused by sub-rupture fatigue loading outpaces repair. Studies have linked fatigue loading with various mechanical, structural, and biological changes associated with pathology. However, the multiscale progression of damage accumulation with respect to area, severity and the distinct contributions of strain level and number of cycles has not been fully elucidated. The objective of this study was to investigate multiscale mechanisms underlying fatigue damage accumulation and their effect on the cellular environment. Using an in situ model in rat tail tendon (RTT), fatigue loading was applied at various strains and cycle numbers to induce fatigue damage. Pre- and post- fatigue diagnostic mechanical testing, second harmonic generation (SHG) imaging, and transmission electron microscope (TEM) imaging were used to investigate extracellular and cellular damage modes at multiple scales. Fatigue loading at strains at or below 1.0% resulted in no significant changes in SHG damage area or severity and no changes in collagen fibril or cell morphology compared with controls. Fatigue loading at strains above 1.5% resulted in greater mechanical changes correlated with increased damage area measured by SHG and collagenous damage observed by TEM. Increased cycles at high strain further altered mechanical properties, increased structural damage severity (but not area), and altered TEM collagen rupture patterns. Cell morphology was similarly progressively affected with increased strain and cycle number. These damage mechanisms that may trigger degenerative changes characteristic of tendinopathy could be targeted as a part of prevention or therapy.

Abstract
Secondary trigger finger caused by trauma to the hand, especially associated with partial flexor tendon rupture, is not a common condition. Thus, the clinical manifestations of these patients are not well-known. The aim of this study is to present secondary trigger finger caused by a neglected partial flexor tendon rupture including discussion of the mechanism and treatment.We retrospectively reviewed the records of 6 patients with trigger finger caused by a neglected partial flexor tendon rupture who had been treated with exploration, debridement, and repairing of the ruptured tendon from August 2010 to May 2015. The average patient age was 41 years (range, 23-59). The time from injury to treatment averaged 4.7 months. The average follow-up period was 9 months (range, 4-18). Functional outcome was evaluated from a comparison between the Quick-disabilities of the arm, shoulder, and hand (DASH) score and the visual analogue scale (VAS) for pain, which were measured at the time of preoperation and final follow up.Four patients showed partial rupture of the flexor digitorum profundus (FDP) tendon and 3 showed partial rupture of the flexor digitorun superficialis (FDS) tendon. Both the FDP and FDS tendons were partially ruptured in 2 patients, and the remaining patient had a partial rupture of the flexor pollicis longus tendon. All patients regained full range of motion, and there has been no recurrence of triggering. The average VAS score decreased from 3.6 (range, 3-5) preoperatively to 0.3 (range, 0-1) at the final follow up. The average Quick-DASH score decreased from 33.6 preoperatively to 5.3 at the final follow up.When we encounter patients with puncture or laceration wounds in flexor zone 2, even when the injury appears to be simple, partial flexor tendon laceration must be taken into consideration and early exploration is recommended.

Abstract
Mechanical stimulation of the healing tendon is thought to regulate scar anisotropy and strength and is relatively easy to modulate through physical therapy. However, in vivo studies of various loading protocols in animal models have produced mixed results. To integrate and better understand the available data, we developed a multiscale model of rat Achilles tendon healing that incorporates the effect of changes in the mechanical environment on fibroblast behavior, collagen deposition, and scar formation. We modified an OpenSim model of the rat right hindlimb to estimate physiologic strains in the lateral/medial gastrocnemius and soleus musculo-tendon units during loading and unloading conditions. We used the tendon strains as inputs to a thermodynamic model of stress fiber dynamics that predicts fibroblast alignment, and to determine local collagen synthesis rates according to a response curve derived from in vitro studies. We then used an agent-based model (ABM) of scar formation to integrate these cell-level responses and predict tissue-level collagen alignment and content. We compared our model predictions to experimental data from ten different studies. We found that a single set of cellular response curves can explain features of observed tendon healing across a wide array of reported experiments in rats–including the paradoxical finding that repairing transected tendon reverses the effect of loading on alignment–without fitting model parameters to any data from those experiments. The key to these successful predictions was simulating the specific loading and surgical protocols to predict tissue-level strains, which then guided cellular behaviors according to response curves based on in vitro experiments. Our model results provide a potential explanation for the highly variable responses to mechanical loading reported in the tendon healing literature and may be useful in guiding the design of future experiments and interventions. Tendons and ligaments transmit force between muscles and bones throughout the body and are comprised of highly aligned collagen fibers that help bear high loads. The Achilles tendon is exposed to exceptionally high loads and is prone to rupture. When damaged Achilles tendons heal, they typically have reduced strength and stiffness, and while most believe that appropriate physical therapy can help improve these mechanical properties, both clinical and animal studies of mechanical loading following injury have produced highly variable and somewhat disappointing results. To help better understand the effects of mechanical loading on tendon healing and potentially guide future therapies, we developed a computational model of rat Achilles tendon healing and showed that we could predict the main effects of different mechanical loading and surgical repair conditions reported across a wide range of published studies. Our model offers potential explanations for some surprising findings of prior studies and for the high variability observed in those studies and may prove useful in designing future therapies or experiments to test new therapies.

Abstract
Musculoskeletal soft tissue injuries are complex phenotypes with genetics being one of many proposed risk factors. Case-control association studies using the candidate gene approach have predominately been used to identify risk loci for these injuries. However, the ability to identify all risk conferring variants using this approach alone is unlikely. Therefore, this study aimed to further define the genetic profile of these injuries using an integrated omics approach involving whole exome sequencing and a customised analyses pipeline. The exomes of ten exemplar asymptomatic controls and ten exemplar cases with Achilles tendinopathy were individually sequenced using a platform that included the coverage of the untranslated regions and miRBase miRNA genes. Approximately 200 000 variants were identified in the sequenced samples. Previous research was used to guide a targeted analysis of the genes encoding the tenascin-C (TNC) glycoprotein and the α1 chain of type XXVII collagen (COL27A1) located on chromosome 9. Selection of variants within these genes were; however, not predetermined but based on a tiered filtering strategy. Four variants in TNC (rs1061494, rs1138545, rs2104772 and rs1061495) and three variants in the upstream COL27A1 gene (rs2567706, rs2241671 and rs2567705) were genotyped in larger Achilles tendinopathy and anterior cruciate ligament (ACL) rupture sample groups. The CC genotype of TNC rs1061494 (C/T) was associated with the risk of Achilles tendinopathy (p = 0.018, OR: 2.5 95% CI: 1.2-5.1). Furthermore, the AA genotype of the TNC rs2104772 (A/T) variant was significantly associated with ACL ruptures in the female subgroup (p = 0.035, OR: 2.3 95% CI: 1.1-5.5). An inferred haplotype in the TNC gene was also associated with the risk of Achilles tendinopathy. These results provide a proof of concept for the use of a customised pipeline for the exploration of a larger genomic dataset. This approach, using previous research to guide a targeted analysis of the data has generated new genetic signatures in the biology of musculoskeletal soft tissue injuries.

Abstract
Blunt traumatic diaphragmatic rupture (BTDR) is uncommon, but is associated with high rates of morbidity and mortality. The purpose of this study was to present our experience with management of this injury. Medical records of 38 patients with BTDR who were treated in our hospital from January 2001 to June 2016 were analyzed retrospectively. The sex, age, cause of injury, location of rupture, mode of diagnosis, time to diagnosis, the presence of herniation and bowel perforation, the presence of preoperative shock and intubation, Injury Severity Score (ISS), associated injuries, comorbidity, the operative procedure, morbidity and mortality, and the predictive factors affecting the outcome of BTDR were evaluated. There were 32 men (84.2%) and 6 women (15.8%) with a mean age of 51.2 years (range 18-84 years). The diagnosis could be preoperatively established in 28 patients (73.7%) with a plain chest X-ray or computed tomography scan. Rupture of diaphragm was left-sided in 31 patients (81.6%), right-sided in 6 (15.8%), and bilateral in 1 (2.6%). Sixteen patients had preoperative shock (systolic blood pressure <90 mm Hg, heart rate >120/min). Initial operative approaches were laparotomy in 22 patients (57.9%) and thoracotomy in 16 (42.1%). Eleven required additional exploration. The rate of additional exploration was higher in patients who initially underwent thoracotomy than laparotomy (56.2% vs 9.1%, P = .003). Patients who underwent additional exploration had a significantly longer operation time (330 minutes vs 237.5 minutes, P = .012), and a significantly higher morbidity rate (72.7% vs 22.2%, P =.008). Overall mortality was observed in 6 patients (15.8%). The mortality was associated with right-sided TDR (P = .042) and preoperative shock (P = .003). Neither ISS nor delay in diagnosis posed a statistically significant risk to the outcome of patients. Intra-abdominal organ injuries are more common than intrathoracic injuries in patients with BTDR, indicating that laparotomy should be the initial approach in these patients. Preoperative shock and right-sided TDR are predictive of mortality after BTDR.

Abstract
Injuries of the flexor finger apparatus are very common. Primarily, it is routinely treated by suture of the tendon. Isolated deep flexor injuries, when the flexion restriction only reaches the DIP joint, are sometimes overlooked by the surgeon or by the patients themselves, especially if the deep flexor is injured, after a closed rupture or cutaneous injury with a small skin wound. The patient is then sent to a department specializing in hand surgery after a few weeks. Subsequent shortening of the tendon apparatus makes flexor suture more difficult or sometimes even impossible. Many ways of suturing the tendons and subsequent treatment are described. The treatment results vary immensely. It depends on the mechanism of injury, injury zone, the suture suture technique used, time that has elapsed since primary treatment, surgeon experience and subsequent postoperative and rehabilitative care. One of them is reconstruction of the flexor apparatus by primary transplantation of an autologous tendon graft. Most commonly, the tendon graft is taken from the palmaris longusfrom the same hand. The tendon graft can subsitute the entire area of zones I and II. The tendon suture is made in the palm proximal to the A1 pulley outside the tendon sheath in the area where the muscular belly of thelumbricalis is located on the tendon of the deep flexor. The distal end is reinserted to the base of the distal phalanx. The primary use of the autologous tendon graft can be used in the reconstruction of obsolete deep-flexor injuries in Zone II, but also in primary treatments. This type of treatment has a number of advantages. Performing the reinforcement of the tendon at the base of the distal phalanxand the suture in the palm of the hand completely eliminates the complications caused by the tendon suture in zone II. There is no injury to the tendon sheath, or the need for intersection of the tendons. The transplanted tendon is smaller in diameter than the deep flexor, so it can also be used for older injuries when the tendon sheath is in partially missing. It removes painful palmar resistance by restoring the right position and a tension of tendon of lumbricalis and the tendon of the deep flexor. This type of reconstruction allows immediate active or semi-rehabilitation of the hand and fingers. Key words:tendon, injury, hand, transplantation, surgery, flexor, reconstruction, rupture, treatment.

Abstract
PURPOSE OF THE STUDY The purpose of the prospective randomised study was to assess the benefits of the platelet-rich fibrin (PRF) application during the anatomic anterior cruciate ligament reconstruction (ACLR) for tendon graft healing. MATERIAL AND METHODS The study included 40 patients with an isolated rupture of the anterior cruciate ligament in the knee. The MRI findings on the tendon graft were evaluated at 6 months and 12 months after the surgery in a total of 33 patients, namely in 10 women/23 men (21 right knee/12 left knee), with the mean age of 29.1 years and at the mean follow-up of 15.9 weeks after the injury. The randomisation using envelopes was carried out at the beginning of arthroscopy either in the group with the PRF application (Group 1) (17 patients) or in the group without the PRF application (Group 2) (16 patients). The followed-up patients underwent the ACLR with targeting the femoral tunnel through anteromedial portal using the autografts of m. semitendinosusand m. graciliswith Tightrope femoral fixation and Inion implant in tibia. In Group 1, during the surgery PRF was applied both in the drilled tunnels (intraosseously) and directly to the surface of the tendon graft itself (intraarticular part). The Group 2 was a control group in which the same intervention was performed, however without the PRF application. In the 6 th and 12 th month after the surgery, the signal intensity of the knee and occurrence of the ACL graft failure, bone (marrow) oedema rate near the tunnels were assessed by an independent radiologist using a 3 Tesla MRI. RESULTS In the 6 th and also in the 12 th postoperative month, neither a complete, nor a partial graft failure was found in the group with PRF, whereas in Group 2 a complete or a partial graft failure was observed in 12.5% (p = 0.23). In the 6th month, a bone marrow oedema near the intraosseous parts of the graft was reported in 94.1% of patients in Group 1 and in 81.3% of patients in Group 2, while in the 12 th month it was 23.5% of evaluated patients in Group 1 and 37.5% patients in Group 2. The differences between the two groups were not statistically significant in the 6 th (p = 0.096) or in the 12 th month (p = 0.43). In the 6 th month, a fully ligamentised graft was found in 52.9% of patients in Group 1 and in 37.5% of patients in Group 2 (p = 0.061), a partially ligamentised graft was present in 47.1% of patients in Group 1 and in 50% of patients in Group 2. In the 12 th month, a fully ligamentised graft was seen in 94.1% of patients in Group 1 and in 75% of patients in Group 2 (p = 0.26) and a partially ligamentised graft was present in 5.9% of patients in Group 1 and in 12.5% of patients in Group 2. In the remaining 12.5% of patients in Group 2, the finding was assessed as a graft with no signs of ligamentisation. DISCUSSION We have not encountered a paper in the Czech or world literature which would present results of a similar study, i.e. which would evaluate the potential benefits of the platelet-rich fibrin application in the course of the anatomic anterior cruciate ligament reconstruction. Majority of studies evaluate the benefits of the application of platelet-rich plasma aimed to achieve a positive effect on the LCA graft healing. CONCLUSIONS Our study proved a higher percentage of ligamentisation and healed grafts into the bone as well as a lower occurrence of graft failure in the group with PRF compared to the group without the PRF application, namely both in the 6 th and in the 12 th month. Nonetheless, the differences between the two groups assessed at the same time were not statistically significant. Key words: anterior cruciate ligament, arthroscopy, anatomic ACL reconstruction, magnetic resonance imaging of the graft, platelet-rich fibrin, graft healing, MRI signal intensity of the graft.

Abstract
We conducted a retrospective study, between 2013 and 2018. The study was conducted by analyzing the comparative imaging of two groups of patients. The two groups comprise 42 patients, 14 women and 28 men aged between 17 and 70 years old, to whom objective variables of statistical relevance were tracked. The results of this study show that there is a significant correlation between an angle value of less than 45° and the rupture of the anterior crossed ligament.

Abstract
A balance between matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) is required to maintain tendon homeostasis. Variation in this balance over time might impact on the success of tendon healing. This study aimed to analyze structural changes and the expression profile of MMPs and TIMPs in human Achilles tendons at different time-points after rupture. Biopsies from 37 patients with acute Achilles tendon rupture were taken at surgery and grouped according to time after rupture: early (2–4 days), middle (5–6 days), and late (≥7 days), and intact Achilles tendons served as control. The histological score increased from the early to the late time-point after rupture, indicating the progression towards a more degenerative status. In comparison to intact tendons, qRT-PCR analysis revealed a significantly increased expression of MMP-1, -2, -13, TIMP-1, COL1A1, and COL3A1 in ruptured tendons, whereas TIMP-3 decreased. Comparing the changes over time post rupture, the expression of MMP-9, -13, and COL1A1 significantly increased, whereas MMP-3 and -10 expression decreased. TIMP expression was not significantly altered over time. MMP staining by immunohistochemistry was positive in the ruptured tendons exemplarily analyzed from early and late time-points. The study demonstrates a pivotal contribution of all investigated MMPs and TIMP-1, but a minor role of TIMP-2, -3, and -4, in the early human tendon healing process.

Abstract
Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination. The parents of the victim pressed charges against the medical staff that was appointed to the cares, blaming them with malpractice. The missed diagnosis of a cardiac congenital diverticulum of the left ventricle, a rare pathology, reflects the trickiness of the medical management that can lead to medico-legal controversies and, even though such rare conditions must be always taken into consideration when investigating possible dysfunction causing the death, diagnostic difficulties, in the case in exam, justify the missed diagnosis intra-vitam of cardiac ventricular diverticulum.

Abstract
BACKGROUND We describe a special, interesting phenomenon found in the anterior horn of the lateral meniscus (AHLM): most tear patterns in the AHLM are distinctive, with loose fibers in injured region and circumferential fiber bundles were separated. We name it as macerated tear. The goal of this study was to bring forward a new type of meniscal tear in the AHLM and investigate its clinical value. MATERIALS AND METHODS AHLM tears underwent arthroscopic surgery from January 2012 to December 2014 were included. Data regarding the integrity of AHLM were prospectively recorded in a data registry. Tear morphology and treatment received were subsequently extracted by 2 independent reviewers from operative notes and arthroscopic surgical photos. RESULTS A total of 60 AHLM tears in 60 patients (mean age 27.1 years) were grouped into horizontal tears (n = 15, 25%), vertical tears (n = 14, 23%), complex tears (n = 6, 10%), and macerated tears (n = 25, 42%). There were 6 patients with AHLM cysts in macerated tear group and one patient in vertical tear group. 60 patients were performed arthroscopic meniscus repairs and were followed-up with averaged 18.7 months. Each group had significant postoperative improvement in Lysholm and IKDC scores (p < 0.05). However, the macerated tear group showed least functional recovery of Lysholm and IKDC scores compared to other groups (p < 0.05). In addition, there were no differences in postoperative range of motion, return to work, or return to sport/other baseline activities between the four groups (p > 0.05). CONCLUSIONS This study demonstrated that the macerated tear is common in the tear pattern of AHLM. However, feasibility of the treatment of this type of meniscal tear, especially the meniscus repairs still requires further study.

Abstract
The formation of connective tissue changes in the spinal canal of rats, caused by the method of intervertebral disc ruptures, in association with a mixture of epidural injection of longidaza and diprospan has been researched. Simultaneous injection of hialuronidase and betamethasone in composition of diprospan and longidaza, revealed a high synergistic effect and anti-fibrotic activity. Combined antifibrosis action of these two drugs is stronger than the sum of the actions of the two drugs in their separate use. Reducion of the maximum thickness of the fibrous layer was 49%, compared with the reference value and reduction of the total area of the fibrous formation was 46%. In our opinion, due to anti-inflammatory effects and the ability to reduce epidural scar adhesion, this complex is promising for its therapeutic use in treatment of spinal epidural fibrosis.

Abstract
The aim of the current in vitro study was to investigate if tissue surface modification with collagenase and addition of the TGF-β3 can increase the number of cells present in meniscus tears repaired with the use of newly developed tissue adhesives based on isocyanate-terminated block copolymers. Cylindrical explants were harvested from the inner part of bovine menisci. To simulate a full-thickness tear, the central core of the explants was removed and glued back into the defect, with or without incubation in collagenase solution prior to gluing. The repair constructs were then cultured with or without addition of TGF-β3, and assessed for their histological appearance. The histological staining of the constructs confirmed that both developed adhesives were not cytotoxic. After 28 days, meniscus cells were present in direct contact with the glues. The addition of TGF-β3 to the culture medium resulted in the presence of cells that formed a sheath inside the simulated tear and in increased cell numbers at the edges of annulus of the explants. In the group in which the tissue was incubated in collagenase and cultured in medium containing TGF-β3, thicker layers of cells were observed. These results suggest that repairing the torn meniscus with tissue adhesives after pre-treatment of the tissue with collagenase and stimulation with TGF-β3 is a very promising treatment method, especially when treating the inner avascular part of the meniscus. Nevertheless, longer-term in vitro and in vivo studies are needed to confirm the beneficial effects of this combination therapy.

Abstract
Rupture of the tibialis posterior tendon associated with ankle fracture is rare and difficult to diagnose. This rupture can be easily overlooked because the clinical examination is limited owing to acute pain related to a closed ankle fracture. Complete rupture of the tibialis posterior tendon can be identified by a loss of tension during ankle fracture fixation, but partial rupture is more difficult to detect because the tibialis posterior tendon can maintain its tension. A few cases of complete rupture of the tibialis posterior tendon combined with ankle fracture have been reported. It is well-known that failure to diagnose a rupture of the tibialis posterior tendon can lead to long-term disability and a planovalgus foot. However, to our knowledge, this is the first report of partial rupture of the tibialis posterior tendon in the English literature. Herein, we describe a patient with a neglected partial rupture of the tibialis posterior tendon combined with a medial malleolar fracture.

Abstract
This article describes penile fracture and testicular rupture and offers recommendations for management. Both conditions occur most commonly after blunt trauma. Diagnosis can be supported by imaging but is usually confirmed on surgical exploration, which in both cases should be carried out promptly. Penile fracture occurs most commonly related to coitus, and surgical correction decreases the risk of long-term erectile dysfunction, deformity and pain. Testicular rupture usually presents with persisting pain and haematoma after trauma, and surgery is recommended to minimize permanent organ damage.

Abstract
BACKGROUND Penile fracture is a rare clinical entity that represents a urologic emergency. It involves traumatic rupture of the tunica albuginea of the corpora cavernosa due to twisting or bending of the penile shaft during erection. OBJECTIVE To determine the differences in preoperative diagnostic evaluation patterns and outcomes of penile fracture patients to investigate the impact of surgical delay on functional outcomes. DESIGN, SETTING, AND PARTICIPANTS A retrospective analysis was performed using data obtained from 137 patients presenting with penile fracture at seven different European academic medical centers between 1996 and 2013. Age, imaging modalities used, timing of surgical intervention, length of tunica albuginea defect, and surgical technique were recorded. Postoperative erectile function outcomes were assessed with the International Index of Erectile Function (IIEF-5), and the presence of postoperative penile curvature was noted. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The association between timing of surgical intervention and postoperative IIEF-5 results was evaluated with discriminant function analysis. RESULTS AND LIMITATIONS The median age of the patients was 34.50 yr (interquartile range [IQR]: 28.0-46.5 yr). Of the 137 patients, 82 (59.85%) underwent penile Doppler ultrasound, and 5 patients (3.64%) were evaluated with magnetic resonance imaging. All patients were treated surgically, and the duration between emergency room admission and surgical intervention was 5.0h (IQR: 3.6-8.0h). The median length of tunica albuginea defect was 10mm (IQR: 8-20mm). Postoperative IIEF-5 scores were 21 (IQR: 12-23) and 23 (IQR: 15-24) at the first and third postoperative months, respectively. Discriminant function analysis revealed that if the surgical intervention was performed >8.23hours after emergency room admission, postoperative erectile function was significantly worse (p=0.0051 at first month and p=0.0057 at third month postoperatively). CONCLUSIONS Our multicenter study showed that delaying surgical intervention results in significantly impaired erectile function. Surgical treatment must be planned as soon as possible to avoid postoperative erectile dysfunction. PATIENT SUMMARY We looked at sexual outcomes following the repair of penile fracture in a large European population. We found that outcomes worsened if surgical repair was delayed.
