RESUMEN
BACKGROUND: Osteoarthritis (OA) is a prevalent joint condition causing pain and disability, especially in the elderly. Currently, OA diagnosis relies on clinical data and imaging, but recent interest in metabolomics suggests that early biochemical changes in biofluids, particularly synovial fluid (SF), could enable an earlier diagnosis and understanding of the disease. METHODS: In this regard, we conducted a lipidomics study in 33 plasma and SF samples from OA patients and 20 OA-free controls to assess the diagnostic value of various lipid metabolites, using UHPLC-QTOF-ESI+MS. RESULTS: In plasma samples, 25 metabolites had area-under-the-curve (AUC) values higher than 0.9, suggesting a very good diagnostic potential for phosphatidic acid PA (16:0/16:0), PA (34:0), phosphatidylethanolamine PE (34:2), glucosylceramide, phosphatidylcholine PC (32:1), and other metabolites while in SF 20, metabolites had AUC values higher than 0.8, the vast majority belonging to lipid metabolism as well. CONCLUSIONS: Although the results align with the previous literature, larger cohort studies are necessary to confirm the diagnostic value of the lipid metabolites.
RESUMEN
BACKGROUND: Schatzker type II fractures usually need to be grafted. Autograft bone from the iliac crest represents the gold standard, but it comes with high rates of morbidity on the donor side. Sticky bone is one of the regenerative therapies that aims to find new solutions to treat bone defects and to overcome the limitation of conventional options regarding bone grafts, due to their content in growth factors, which offer osteo-induction and osteo-conduction properties. Notably, regenerative dentistry has been at the forefront of applying these products in bone regeneration, demonstrating that PRF produces a highly promising "sticky bone" when combined with bone chips. To the best of our knowledge, this grafting technique has not been used in the orthopedic field to date. METHODS: The subject was a 53-year-old woman with a Schatzker type II tibial plateau fracture, for which a new autologous bone grafting technique, i.e., sticky bone, was used for the treatment of the fracture. RESULTS: This case reports the effectiveness of sticky bone as autologous bone graft used in Shatzker type II tibial plateau fracture. As an indispensable component of regenerative medicine, it seems to be an ideal biologic graft with a fibrin-rich structure that provides effective treatment in impressed tibial plateau fractures. CONCLUSION: Sticky bone showed promising results and should be considered in the future as an appropriate bone implant.
RESUMEN
OBJECTIVES: This study delves into the cutting-edge field of deep learning techniques, particularly deep convolutional neural networks (DCNNs), which have demonstrated unprecedented potential in assisting radiologists and orthopedic surgeons in precisely identifying meniscal tears. This research aims to evaluate the effectiveness of deep learning models in recognizing, localizing, describing, and categorizing meniscal tears in magnetic resonance images (MRIs). MATERIALS AND METHODS: This systematic review was rigorously conducted, strictly following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Extensive searches were conducted on MEDLINE (PubMed), Web of Science, Cochrane Library, and Google Scholar. All identified articles underwent a comprehensive risk of bias analysis. Predictive performance values were either extracted or calculated for quantitative analysis, including sensitivity and specificity. The meta-analysis was performed for all prediction models that identified the presence and location of meniscus tears. RESULTS: This study's findings underscore that a range of deep learning models exhibit robust performance in detecting and classifying meniscal tears, in one case surpassing the expertise of musculoskeletal radiologists. Most studies in this review concentrated on identifying tears in the medial or lateral meniscus and even precisely locating tears-whether in the anterior or posterior horn-with exceptional accuracy, as demonstrated by AUC values ranging from 0.83 to 0.94. CONCLUSIONS: Based on these findings, deep learning models have showcased significant potential in analyzing knee MR images by learning intricate details within images. They offer precise outcomes across diverse tasks, including segmenting specific anatomical structures and identifying pathological regions. Contributions: This study focused exclusively on DL models for identifying and localizing meniscus tears. It presents a meta-analysis that includes eight studies for detecting the presence of a torn meniscus and a meta-analysis of three studies with low heterogeneity that localize and classify the menisci. Another novelty is the analysis of arthroscopic surgery as ground truth. The quality of the studies was assessed against the CLAIM checklist, and the risk of bias was determined using the QUADAS-2 tool.
RESUMEN
The present research study aimed to assess magnetic resonance imaging (MRI) changes and histological findings in the therapeutic effects of microfractures in the treatment of complex animal knee lesions resulting from osteochondral and meniscal defects resulting from non-total meniscectomies. The anterior cruciate ligament lesions are also proven to facilitate the development of osteoarthritis in the knee and worsen the prognosis. Surgery was performed on the right knee joint of 22 male rabbits in order to partially remove the anterior horn of the internal meniscus and to induce an osteochondral defect at the level of the internal femoral condyle. The induced lesion complex was aimed to simulate a clinical situation that occurs frequently in orthopedic practice when young adults undergo partial meniscectomy and at the time of surgery, an osteochondral defect is diagnosed. Rabbits were separated into two study groups: the control (C1) group and the microfractures (MF2) group. After the induced cartilage defect and partial meniscectomy, both groups were followed-up for six months using detailed MRI. Also, anatomical specimens were histologically analyzed to show modifications and signs of healing process, along with complications, in the study group. The results showed that the microfracture group had better results concerning articular surface defect healing in comparison to the control group. Our results suggest that microfractures do improve results concerning surface contact healing and serial MRI studies can be useful in observing the remodeling process in dynamics.

Background: This study aimed to compare the outcomes of the single-incision technique with a distal biceps repair system versus the modified double-incision technique, specifically the Morrey-modified approach, Krackow sutures, and drill holes, for the management of acute and chronic distal biceps tendon rupture. The study was conducted at the Orthopedic-Traumatology Clinic II of SCJUPBT Timisoara, Romania, between 2014 and 2022. Methods: A total of sixty-nine patients with acute distal biceps tendon rupture and five patients with chronic distal tendon rupture were included in the study. Forty-eight cases underwent the single-incision technique with the distal biceps repair system, while twenty-four patients were treated with the modified double-incision technique. Results: Both surgical techniques demonstrated favorable outcomes in terms of successful tendon repair and functional restoration. However, the single-incision technique exhibited slightly superior results in terms of patient satisfaction, range of motion, and postoperative rehabilitation. The modified double-incision technique showed comparable outcomes but had a higher incidence of complications, particularly related to wound healing. Conclusion: The single-incision technique with the distal biceps repair system and the modified double-incision technique, including the Morrey-modified approach, Krackow sutures, and drill holes, are effective surgical approaches for the management of distal biceps tendon rupture. The single-incision technique yielded better functional outcomes and patient satisfaction, while the modified double-incision technique had a higher risk of complications. Further research with larger sample sizes and longer follow-up periods is necessary to validate these findings and determine the most appropriate surgical approach for distal biceps tendon rupture.
RESUMEN
(1) Background: Osteochondromas are the most common benign bone tumors, primarily found in long bones, while scapular osteochondromas are rare and account for less than 1% of all osteochondromas. (2) Methods: We present a case of a young female patient with a unique presentation of scapular osteochondroma. The patient exhibited superomedial scapula angle osteochondroma with winging, a rare manifestation of scapular osteochondroma. The patient had a slow-growing mass on the left scapula for several years. Physical examination revealed a visible deformity with significant winging of the scapula. Imaging studies demonstrated a large osteochondroma arising from the superomedial angle of the left scapula, with a bony stalk. (3) Results: Surgical excision was performed, and histopathological analysis confirmed the diagnosis of osteochondroma. Following the surgery, the patient experienced a significant improvement in scapular winging. A comprehensive literature review revealed only a limited number of reported cases of scapular osteochondroma with winging, underscoring the significance of this case report as a valuable addition to the existing literature. The diagnosis of scapular osteochondroma should be considered in the differential diagnosis of patients presenting with a scapular mass, particularly when associated with winging. Surgical excision is the recommended treatment, and complete excision is crucial to prevent recurrence. (4) Conclusions: This case report highlights a rare presentation of scapular osteochondroma with winging and emphasizes the importance of considering this diagnosis in patients with scapular masses accompanied by winging. The successful surgical intervention in our case resulted in significant improvement. Clinicians should be aware of this entity and consider prompt surgical intervention for complete excision, ensuring optimal patient outcomes and preventing recurrence. Further research and additional case reports are necessary to enhance our understanding of scapular osteochondroma and its varied clinical presentations. Furthermore, comprehensive studies involving larger patient cohorts are necessary to explore the full spectrum of clinical presentations of scapular osteochondromas. By documenting and analyzing a wider range of cases, including variations in tumor location, size, and associated symptoms, researchers can identify patterns and establish more accurate diagnostic criteria. This will facilitate early detection and appropriate management of scapular osteochondromas, ultimately improving patient outcomes.
RESUMEN
Posterior cruciate ligament (PCL) injuries, though less common than other knee ligament injuries, pose significant management challenges. This study aimed to systematically review and analyze the current evidence on the use of point-of-care ultrasound (POCUS) for the evaluation and management of PCL injuries. It was hypothesized that POCUS has comparable diagnostic accuracy to magnetic resonance imaging (MRI) and that the use of POCUS improves patient outcomes and reduces healthcare costs. A comprehensive systematic review of articles published up to April 2023 was conducted using PubMed, Web of Science, Cochrane, and Scopus databases and adhered to the PRISMA guidelines. Studies were selected based on relevance to the research question, with a focus on diagnostic accuracy, reliability, clinical utility, and cost-effectiveness of POCUS in PCL injuries. Seven studies, analyzing a total of 242 patients with PCL injuries, were included. The reported sensitivity and specificity of POCUS for diagnosing PCL injuries ranged from 83.3% to 100% and 86.7% to 100%, respectively, across the studies. In one study, POCUS demonstrated a positive predictive value (PPV) of 87.9% and a negative predictive value (NPV) of 82.4%. Additionally, three studies reported 100% accuracy in PCL injury detection using POCUS, suggesting a substantial potential for cost savings by eliminating the need for MRI. This systematic review supports the use of POCUS in the evaluation and management of PCL injuries, suggesting that POCUS is a reliable, cost-effective tool with high diagnostic accuracy comparable to that of MRI, offering the potential to improve patient outcomes and reduce healthcare costs. The data collated in this review can inform clinical practice and guide future research in the field.
RESUMEN
(1) Background: Total hip arthroplasty (THA) is one of the most common procedures used for adult hip reconstruction, employing mainly two types of prostheses: cemented (CHP) and cementless (CLHP). This study aims to analyze the impact of the COVID-19 pandemic on THA with CHP and CLHP, in terms of the benefit/cost ratio. (2) Methods: This article represents a retrospective analysis of the differences concerning the benefit/cost ratio between THA with the two types of prostheses in 2950 patients admitted for THA in the two orthopedic clinics of our hospital between 1 January 2015-1 March 2020 in comparison with 1005 THA subjects seen between 1 April 2020-31 December 2022. (3) Results: In the first period, THA with CHP was performed in 45.83% of cases, while CLHP was used in 54.16% of patients. During the COVID-19 period, CHP was inserted in 52% of THA patients, while the other 48% had CLHP inserted, with a hospitalization duration reduced by over 50% for both types of implants (p Ë 0.001). (4) Conclusions: CHP offered good outcomes, with quicker mobilization, and shorter hospitalization duration, compared to CLHP, but optimization of the patients' management can be achieved mainly by reducing the length of hospitalization through an appropriate preoperative patient evaluation through a multidisciplinary approach, an aspect that was proven during the COVID-19 pandemic.
RESUMEN
Objective:The current study included a total of 10 patients, both males and females, who gave their consent to participate in the study and underwent clinical and ultrasound examinations. All patients had a history of carpal tunnel symptoms like tingling, numbness, nocturnal paraesthesia and weakness of the hand (loss of pinch and grip strength) for more than 12 months. Aim: The aim of our study was to investigate the morphopathology of the median nerve in clinically diagnosed carpal tunnel thought static and dynamic ultrasound assessment. Material and methods: The present study included a small group of 10 patients aged over 18, both males and females, who had a history of carpal tunnel symptoms for over 12 months and a positive Tinel's and reverse Phalen's tests during clinical examination. Ultrasound was performed by an experienced orthopaedic surgeon with musculoskeletal ultrasound training. Ultrasound evaluation was made using a standardized method and included transverse and longitudinal static examination and dynamic examination of the median nerve in the carpal tunnel. Side-to-side evaluation was performed and differences of more than 10 mm width in the median nerve have been recorded, which was considered to be a positive test for carpal tunnel syndrome. Furthermore, the major advantage of the dynamic evaluation brought by performing the palmar hand and finger flexion test, while investigating the movement trajectory of the median nerve in the carpal tunnel, provides superior imagistic documentation of this pathology. Results:Dynamic evaluation of the median nerve has shown a decreased mobility of the nerve in the carpal tunnel on the side that also had an increased area value of the median nerve width. If in the asymptomatic hand at the time of dynamic evaluation, the median nerve would suddenly slide under the flexor tendons; therefore, we noted results only of a slight translational movement of the nerve in the carpal tunnel on the affected side. A side-to-side difference in the median nerve area, with values ranging between 3 mm up to 9 mm, was found in our patients. Furthermore, thenar atrophy has been discovered in patients with pre-existing carpal tunnel symptoms for more than 24 months. Conclusion:The present study highlights the importance of ultrasound assessment as an accessible static and dynamic evaluation tool. Ultrasound can be used as an in-office imaging tool to complete the clinical diagnosis of carpal tunnel syndrome by studying the morphology and morphopathology of the median nerve in the carpal tunnel through a bilateral standardized examination technique.
RESUMEN
Osteoarthritis (OA) is one of the most prevalent degenerative joint diseases in older adults and a leading cause of disability. Recent research studies have evidenced the importance of mi-croRNAs (miRs) in the pathogenesis of OA. In the present review, we focused on current literature findings on dysregulated miRs involved in the pathophysiology of OA. From the 35 case-control studies including OA patients compared to healthy controls, a total of 54 human miRs were identified to be dysregulated in OA. In total, 41 miRs were involved in the pathophysiological processes of OA, including apoptosis, inflammation, and proliferation, having either a protective or a progressive role in OA. The discovery of altered miR levels in OA patients compared to healthy controls determines a better understanding of the molecular mechanisms involved in the pathophysiology of OA and could open novel horizons in the field of orthopedics.
RESUMEN
(1) Background: Mild and moderate hemophilia, synonymous with non-severe hemophilia (NSH), are of constant interest for the clinicians. Bleeding occurs usually after trauma, injury, surgery, or inhibitor development, sometimes leading to a shift of the clinical phenotype from mild to severe, even with life-threatening and unexpected outcomes. (2) Methods: We performed a retrospective observational study conducted on 112 persons with congenital coagulopathies, 26 of them with NSH, admitted to our clinic in the period 2000 to 2022. For the diagnosis, we used laboratory studies (complete blood cell count, coagulation assays, biochemistry, thromboelastography, genetic tests) and imaging investigations (X-ray, ultrasound, CT, MRI). We selected four cases confronted with pitfalls of diagnosis and evolution in order to illustrate the sometimes provocative field of NSH. (3) Results: Confronted with challenging cases with under-, missed or delayed diagnosis and severe consequences, we aimed at presenting four such selected cases with mild or moderate hemophilia, real pitfalls in our clinical activity. (4) Conclusions: In the field of NSH, if not timely recognized, tending sometimes to remain ignored by caregivers and patients themselves, we can be confronted with challenging diagnostic situations and life-threatening bleeds.
RESUMEN
Osteoarthritis (OA) is a common, frequently met degenerative disease, that generates pain and decreasing functionality; risk of suffering from this disorder increases with ageing. Being a complex disease, treatment is often difficult due to complications. Knee OA therapy demands a strategy that specialists agree with in considering the clinical symptoms and the disease evolution. The initial management of its treatment should be conservative requiring both a pharmacological and a non-pharmacological approach. If this conservative, noninvasive therapy fails, the surgical approach is discussed. The present review focused on the assessment of therapy choices for patients with knee OA, in order to reduce pain and enhance functionality and knee range of motion, underlying benefits and advantages for each choice. Existing data of available treatment for knee OA, both surgical and nonsurgical were analyzed, focusing on the latest results, indications, developments, and level of evidence provided by the literature in the topic.
RESUMEN
In the field of orthopedic surgery, cemented total knee arthroplasty (TKA) is considered to be one of the gold standards. However, there are categories of patients (i.e., obese and morbidly obese patients, younger than 65 years old) among whom cemented TKA has however a high failure rate. Moreover, the frequency of using uncemented TKA is increasing due to the potential benefits of long-term biological fixation, being an innovative field that addresses a new generation orthopedic surgical treatment which is more suitable for young patients who have good bone quality (good to very good, in terms of density). The survival rates and functional results of the latest generation of cementless TKAs may be similar to functional results and survival rates of cemented prosthesis. In conclusion, this review-type article can be considered a powerful database, extremely informative, dense, and focused on the topic mentioned above, in the interest of all medical professionals and all interested individuals.
RESUMEN
AIM: The aim of our study was to assess the therapeutic effects of platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) in an animal knee lesion complex associating a large osteochondral defect and meniscal defect resulted from partial meniscectomy, a clinical situation that occurs quite often in orthopedic practice. MATERIALS AND METHODS: Twenty-one male rabbits were included in the study, and all underwent initial surgery on the right knee to create the osteochondral defect on the internal femoral condyle, and remove the anterior horn of the internal meniscus, simulating a clinical situation. Rabbits were separated in three study groups: control, PRP group, in which three PRP injections were administered, and BMAC group, in which one single BMAC injection was administered. At the end of the six months follow-up period, knees were harvested and further analyzed using confocal microscopy and three-dimensional (3D) reconstruction of the articular surface. RESULTS: Therapeutic groups had better results concerning articular surface remodeling and joint degeneration indicators in comparison to trauma group. CONCLUSIONS: Our results suggest that using post-operative regenerative therapies does improve final results concerning surface contact remodeling that was investigated using confocal microscopy and should be considered a valid treatment adjuvant in managing patients with this type of lesion complex, as it improves global joint outcome.

Brodie's abscess is a rare form of sub-acute osteomyelitis that implies the collection of pus inside bone tissue. The present paper presents an extremely rare case of Brodie's abscess located in the distal femur in a young male patient who refused medical care for three years and presented directly with spontaneous fistula and septic complications. Laboratory tests also suggested chronic septic alterations. Complex imaging investigations including X-ray (RX), computer tomography (CT) and Magnetic Resonance imaging (MRI) confirmed the diagnosis with characteristic aspects, such as the penumbra sign on the T1 weighted MRI image. Management included aggressive debridement, defect reconstruction, and long-term specific antibiotics according to culture harvested intra-operatively. Evolution was positive with inflammatory blood tests returning to physiological values within four weeks and patient full recovery within six months, without any physical deficits. The novelty aspect found in this case presentation is represented by the long-term natural evolution of this pathology, and the fact that even in these conditions, the Brodie's abscess did not evolve into a 'malignant' septic condition, but remained rather benign until the spontaneous fistula prompted the patient to seek medical care.

Since loss of meniscus is correlated with an increasing risk for osteoarthritis, meniscal scaffolds are proposed as new strategies. Development of a suitable scaffold has to take into account differing meniscus thickness, exposure to compressive and tensile forces combined with high porosity and biocompatibility of the material. After physical testing of three flat scaffolds composed of different modified polyglycolic acid (PGA) fibers, a three-dimensional meniscus-shaped PGA-hyaluronan implant was generated. Micro-computed tomography showed 90% porosity in the outer area with 50% in the inner area of the implant. Biocompatibility and expression of meniscus typical cartilaginous genes were shown for human meniscus cells cultivated in the implant with 10% human serum or 5% platelet-rich plasma for 14 days in vitro. The proof-of-concept study in sheep demonstrated proteoglycan- and collagen type I-rich repair tissue formation in partial meniscectomy combined with a meniscus-shaped PGA-hyaluronan implant after 6 months. In contrast, the control showed nearly no repair tissue formation. Thus, meniscus-shaped PGA-hyaluronan implants might be a suitable therapeutic approach to support repair tissue formation in partial meniscectomy.

OBJECTIVES: The aim of our study was to assess the incidence of night-time voiding in a population of male patients with hip fracture, and to analyze the correlations between the severity of the lower urinary symptoms and the other most significant comorbidities of the patients. PATIENTS AND METHODS: We have initially selected a group of patients containing all males admitted into a Department of Orthopedic Surgery with the diagnosis of hip fracture, with indication for replacement surgery, over a four-year period. Applying well-defined inclusion and exclusion criteria, we have selected all the patients who have reported that falling during the night, on the way to the toilet (for micturition), was the event leading to the hip fracture. A comprehensive medical history and the International Prostate Symptom Score (IPSS) Questionnaire were gathered from all the patients and the obtained data were analyzed. RESULTS: From a total of 363 patients with hip fractures, 68 cases were attributable to night-time voiding. The detailed analysis of the 68 patients has shown that all of them had significant nocturia (2.72 episodes of voiding per night, in average), but only 11 of them were already diagnosed with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH). Moreover, only four of the eleven patients diagnosed with BPH were taking specific therapy at the moment of their falling leading to hip fracture. Subsequent analysis has shown that a group of 45 patients with no previously known co-morbidities, had similar IPSS score results with the total group of 68 patients. CONCLUSIONS: Night-time voiding and LUTS are underdiagnosed in the general male population, as they represent significant risk factors for hip fractures due to falling during the night. The low level of BPH/LUTS therapy adherence adds a supplementary risk for falling during the night.
RESUMEN
OBJECTIVE: In countries with low factor concentrate consumption, disabling joint disease remains the major morbidity in patients with haemophilia. The objective of the present analysis is to express the trend and profile of invasive orthopaedic interventions in our country with low usage of factor replacement, lacking the prophylaxis program until recent years. PATIENTS AND METHODS: This retrospective descriptive study was conducted in our university centre in Timisoara with long-lasting experience in haemophilia care, which succeeded in developing an exceptionally valuable genuine comprehensive inter-institutional cooperation. This study refers to 115 invasive interventions performed on 97 patients: 83 with haemophilia A, 10 with haemophilia B and 4 with von Willebrand disease in the period of 2001 to 2017; 17 of them had inhibitors, 5 developing inhibitors after the intervention. RESULTS AND DISCUSSION: The cohort of patients consisted mostly of young adults, aged between 7 and 49 years. The vast majority of them, 91.3% of the patients, had the burden of severe chronic arthropathy. This was the reason for 95 interventions, with programmed solution. In 20 cases the cause of invasive interventions was emergency. Knee and hip replacement represented 28% of the major interventions. The complications we encountered were excessive bleeding (12.2%), infection (13%) and inhibitor development (4.3%). CONCLUSION: Surgery is a demanding intervention in patients with haemophilia, which unfortunately cannot be ignored in our country. Hopefully, the improved availability and accessibility to replacement therapy will eliminate the necessity of these interventions, optimizing the outcomes for the next generations.

Although osteochondral fractures of the lateral femoral condyle are uncommon, fixation of the fragments is recommended, mostly when is about young athletes with such post-traumatic pathology. We present a case of a professional handball player teenager female, with a lateral femur condylar osteochondral fracture after a fall with the right knee in extension and in internal rotation. Magnetic resonance imaging (MRI) showed an osteochondral fracture of the lateral femoral condyle, 34.6 mm on long axis, impossible to manage arthroscopically, because of the size and the location of the detached fragment. The solution was the lateral knee arthrotomy allowing the evacuation of the hemarthrosis and preparation of the fracture site, then reduction and fixation of the fracture with absorbable cannulated pins. This procedure is of choice only when is enough bone in the detached fragment to permit the internal fixation and bone-to-bone healing with cartilaginous tissue stabilization through the fibro-cartilaginous rim that would seal the cartilage surface. Postoperative MRI proves that the fragment is settled in its hooked position with repairing of the articular congruity, so the recovery exercises program allow the regaining of the knee mobility with a restart of her sportive activity later.
