Magnetic resonance imaging combined with histological evaluation of repair process using the microfracture technique in an association of osteocartilaginous and meniscal surgically induced lesions of the knee. In vivo experiment on a rabbit model.

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.

Comparative Analysis of Surgical Approaches for Distal Biceps Tendon Rupture: Single-Incision Technique versus Double-Incision Technique.

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.

Superomedial Scapula Angle Osteochondroma with Winging in a Young Female Patient-Case Report and Literature Review.

(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.

Point-of-Care Ultrasound for the Evaluation and Management of Posterior Cruciate Ligament Injuries: A Systematic Review.

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.

Unexpected Repercussions of the COVID-19 Pandemic on Total Hip Arthroplasty with Cemented Hip Prosthesis versus Cementless Implants.

(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 ˂ 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.

Static and Dynamic Ultrasound Evaluation of the Median Nerve Morphopathology in Carpal Tunnel Syndrome Diagnosis.

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.

Osteoarthritis and microRNAs: Do They Provide Novel Insights into the Pathophysiology of This Degenerative Disorder?

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.

Challenges in the Diagnosis and Management of Non-Severe Hemophilia.

(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.

Therapeutic approaches in the management of knee osteoarthritis (Review).

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.

Highlighting the advantages and benefits of cementless total knee arthroplasty (Review).

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.

Comparing PRP and bone marrow aspirate effects on cartilage defects associated with partial meniscectomy: a confocal microscopy study on animal model.

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.

Rare Intercondylar Distal Femoral Brodie's Abscess in a 21-Year-Old Man Who Refused Medical Care for Three Years after Initial Symptoms.

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.

Meniscus-shaped cell-free polyglycolic acid scaffold for meniscal repair in a sheep model.

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.

Are night-time voiding and lower urinary tract symptoms significant risk factors for hip fractures caused by falling during the night in male subjects?

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.

Current Trend of Invasive Orthopaedic Interventions for People with Haemophilia in Romania: Single Centre Experience.

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.

The utility of indirect imagistic signs in the diagnosis of anterior cruciate ligament ruptures.

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.

Clinical and morphological aspects of lateral femoral condyle status after an osteochondral fracture. A case report.

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.

A cross-sectional analysis of joint status and quality of life in children and adolescents with haemophilia in Romania.

BACKGROUND: Haemophilia is a congenital disorder of coagulation with high economic burden due to its requirement for an expensive, lifelong replacement therapy, with additional costs for the frequent complications and for the severe handicapping consequences. The objective of this cross-sectional study aimed at giving an insight into the health condition of young haemophiliacs in the absence of a regular prophylactic therapy. METHODS: It was conducted on a heterogeneous group of 37 children and adolescents (4-24 years of age), with similar on demand therapeutic regimen, coming from the whole country, focusing on the joint status by using the Haemophila Joint Health Score (HJHS) system and on quality of life (QoL) by using the EQ-5D-3L-Y questionnaire. RESULTS: The results revealed an impressive situation: 70.3 % with chronic arthropathy, 19 % with target joints, 69 % with multiple joint involvement, mainly elbow (41 %) and knee (34 %), joint damage starting in the age group 6-12 years (18.18 % arthropathy vs. 96 % in the age group above 12 years). Joint score (6.67 ± 7.92), gait score (0.75 ± 1.14) and HJHS (7.43 ± 8.78) were highly correlated (r = 0.7, p = 0.001) with the annualised bleeding rate ABR (16.2 ± 12.1). They impacted the QoL in all domains, also expressed by a VAS of 68.39 ± 21.6. CONCLUSION: We concluded that in the situation of an international consensus that prophylactic replacement can prevent cost-effectively and cost-efficiently the deleterious joint damages, our study is supporting the introduction even of secondary and tertiary prophylaxis in young patients in our country.

Variable relations of the trochlear nerve with the pontomesencephalic segment of the superior cerebellar artery.

The superior cerebellar artery (SCA) is, perhaps, the most anatomically constant cerebellar artery which, in its lateral pontomesencephalic course, is crossed above by the trochlear nerve (CNIV). The SCA may determine, as an offending vessel, CNIV compression and superior oblique myokymia and thus surgical decompression may be indicated. In this regard an accurate knowledge of the variational possibilities of the SCA-CNIV is needed. Such rare neurovascular variants are reported here. The variables are determined by the length of the SCA, and the course of the CNIV as referred to the rostral (RT) and caudal (CT) trunks of the SCA. The CNIV may be pinched between the origins of the RT and CT, may pass above the RT or the SCA main trunk, and even between the primary branches of the RT. The CNIV was found compressed between the RT and the brainstem. Perhaps the most spectacular variation was a CNIV coursing through an arterial ring formed by the RT and CT which were anastomosed distally to the CNIV. The possibilities of neurovascular relations between the CNIV and the SCA should be considered when CNIV palsy, or surgical decompression, are estimated.

Thermographic and microscopic evaluation of LARS knee ligament tearing.

Damage to knee articular ligaments causes important functional problems and adversely affects particularly the stability of the knee joint. Several methods were developed in order to repair damage to the anterior cruciate ligament (ACL), which employ autografts, allografts, as well as synthetic ligaments. One such synthetic scaffold, the ligament advanced reinforcement system (LARS) synthetic ligament is made of non-absorbing polyethylene terephthalate fibers whose structure allow tissue ingrowths in the intra-articular part, improving the stability of the joint. The LARS ligament is nowadays widely used in modern knee surgery in the Europe, Canada, China or Japan. This paper evaluates LARS ligament from two perspectives. The first regards a study done by the Orthopedics Clinic II, Timisoara, Romania, which compared results obtained by employing two techniques of ACL repair - the Bone-Tendon-Bone (BTB) or LARS arthroscopic, intra-articular techniques. This study found that patients treated with the BTB technique presented with an IKDC score of 45.82±1.14 units preoperative, with increasing values in the first nine months after each implant post-surgical ligament restoration, reaching an average value of 75.92 ± 2.88 units postoperative. Patients treated with the LARS technique presented with an IKDC score of 43.64 ± 1.11 units preoperative, and a score of 77.32 ± 2.71 units postoperative. The second perspective describes the thermographic and microscopic analysis of an artificial knee ligament tearing or loosening. The objective of the study was to obtain information regarding the design of artificial ligaments in order to expand their lifespan and avoid complications such as recurring synovitis, osteoarthritis and trauma of the knee joint. Thermographic data has shown that tearing begins from the inside out, thus improving the inner design of the ligament would probably enhance its durability. An optical microscope was employed to obtain images of structural damage in the inner layers, for use in further analysis of the tears. In conclusion, the LARS artificial ligament, like the BTB technique, displays both advantages and disadvantages. It is important to understand that these two options of ACL lesion repair are not competing. LARS could, in addition to its use in primary ACL ruptures, be utilized in revisions of autologous graft rupture post primary ACL repair.
