Costos directos en el tratamiento del pie diabético Unidad de Pie Diabético. Hospital de Clínicas. Universidad de la República

En el mundo un paciente diabético gasta entre dos y tres veces más que el no diabético. El pie diabético disminuye la calidad de vida, aumenta la morbimortalidad y la carga económica del sistema de salud. Objetivo: comunicar la investigación realizada sobre costos directos en el tratamiento de la úlcera del pie diabético. Material y método: estudio observacional, descriptivo, retrospectivo de pacientes asistidos en la Unidad de Pie del Hospital de Clínicas, Universidad de la República, entre octubre de 2014 y septiembre de 2016. Se estimaron gastos directos del tratamiento ambulatorio e internación a través de información de la historia clínica. El horizonte de tratamiento fue de tres meses. Se calcularon los gastos en unidades reajustables (UR), pesos y dólares. Los gastos se actualizaron a octubre del 2022 utilizando el índice de precios al consumo (IPC), ajustado a la tasa de inflación acumulada. Resultados: incluimos 49 pacientes, 11 mujeres y 38 hombres, edad promedio 61,5 años. El gasto general fue mayor a 400.000 dólares, con el mayor costo en gastos de internación. El gasto total promedio por paciente fue de 8.799 dólares. El tratamiento convencional fue 3.707,93 dólares, la amputación mayor 32.003,61 dólares y amputación menor 12.385,34 dólares. El gasto en internación fue muy superior al del paciente ambulatorio. En emergencia, 28 pacientes gastaron 4.396 dólares. El incremento de costos al año 2022 fue de 37,45%, suponiendo un gasto general de 16.682.993,4 pesos o 410.830,2 dólares. Conclusión: primera evaluación en nuestro país de estimación de gastos en pie diabético. El costo de la úlcera genera una carga económica notoria y en aumento. La gravedad inicial de la úlcera determina ingresos con elevados costes. Los gastos de internación y amputaciones representan la mayor erogación económica.

On a global scale, a diabetic patient incurs healthcare expenses that are 2 to 3 times higher than those of a non-diabetic individual. Diabetic foot syndrome reduces the quality of life, increases morbidity and mortality, and places an economic burden on the healthcare system. Objective: Communicating the research conducted on direct costs in the treatment of diabetic foot ulcers. Method: Observational, descriptive, retrospective study of patients treated at the Foot Unit of the Hospital de Clínicas (UDELAR) between October 2014 and September 2016. Direct treatment costs for outpatient care and hospitalization were estimated using information from the medical records. The treatment horizon extended over a period of 3 months. Expenses were calculated in readjustable units, Uruguayan pesos (UYU), and United States dollars (USD). Expenses were updated to October 2022 using the Consumer Price Index (IPC) adjusted for the cumulative inflation rate. Results: 49 patients were included in the study: 11 women and 38 men, average age was 61.5 years old. The overall expenditure exceeded 400,000 USD, with the highest cost attributed to hospitalization expenses. The average total expenditure per patient amounted to 8,799 USD. The cost of conventional treatment was 3,707.93 USD, major amputation represented USD 32,003.61, and minor amputation USD 12,385.34. Hospitalization expenses significantly exceeded those of outpatient care. In the emergency department, 28 patients spent USD 4,396. The increase in costs by the year 2022 amounted to 37.45%, resulting in a total expenditure of UYU 16,682,993.4 (Uruguayan pesos) or USD 410,830.2. Conclusions: It was the first assessment in our country to estimate diabetic foot costs. The cost of ulcer management imposes a significant and increasing economic burden. The initial severity of the ulcer results in hospitalization which implies high associated costs. Hospitalization and amputation costs constitute the most substantial economic expenditure.

Introducción: las clasificaciones de pie diabético (PD) son una herramienta que tienen el objetivo de mejorar la comunicación entre los profesionales, la referencia y contrarreferencia; proporcionar un pronóstico; ayudar en la valoración de las lesiones, y contribuir con fines estadísticos. Objetivos: describir las características de los pacientes que se presentaron al consultorio o a la guardia con un PD durante un período de 3 meses, determinar el riesgo según cinco clasificaciones (Texas, IDSA, San Elián, WIfI y SINBAD) y evaluar su evolución a 6 meses en relación con el grado de gravedad determinada por cada clasificación. Materiales y métodos: se analizaron 312 pacientes de 15 instituciones en Argentina. Para el análisis se utilizó la calculadora de clasificaciones de pie diabético/score de riesgo del Comité de Pie Diabético de la Sociedad Argentina de Diabetes. Resultados: el 43% de los pacientes (n=133) requirió internación al momento de la primera consulta y el 61% (n=189) había consultado previamente. El porcentaje de amputación mayor total fue de 8,33% (IC 95%; 5,5-11,9) (n=26) y el de amputación menor de 29,17% (IC 95%; 24,2-34,6) (n=91). A los 6 meses, el porcentaje de muerte fue de 4,49% (IC 95%; 2,5-7,4) (n=14), el 24,3% (IC 95%;19,6-29,5) presentaba la herida aún abierta (n=76), el 58,0% (IC 95%; 52,3-66,5) (n=181) cicatrizó y el 7,37% se perdió del seguimiento (n=23). Las clasificaciones de San Elián y WIfI se relacionaron con amputación mayor, cicatrización y muerte. En relación a la clasificación de Texas, el 49% de los pacientes presentó herida penetrante a hueso o articulación (Texas 3), con o sin infección. El 65,3% de las amputaciones mayores y el 78,6% de las muertes se produjeron en pacientes con isquemia. El punto de corte de San Elián para amputación mayor fue 20. Conclusiones: conocer los datos locales permite organizar los recursos para mejorar la atención de los pacientes.

Introduction: the classifications of diabetic foot (DF) are a tool that aims to improve communication between professionals, referral and counter-referral, provide a prognosis, help in the assessment of lesions, and contribute to statistical purposes. Objectives: to describe the characteristics of patients who presented to the clinic or emergency department with DF over a period of 3 months, determine the risk according to 5 classifications (Texas, IDSA, SEWSS, WIfI, and SINBAD), and evaluate their evolution at 6 months in relation to the severity degree determined by each classification. Materials and methods: 312 patients from 15 institutions in Argentina were analyzed. The Diabetic Foot Classification Calculator/Risk Score from the Diabetic Foot Committee of the Argentina Argentina Diabetes Society was used for the analysis. Results: 43% of patients (n=133) required hospitalization at the time of the first consultation and 61% (n=189) had previously consulted. The total major amputation percentage was 8.33% (95%CI; 5.5-11.9) (n=26), and the minor amputation percentage was 29.17% (95% CI; 24.2-34.6) (n=91). At 6 months, the death rate was 4.49% (95% CI; 2.5-7.4) (n=14), 24.3% (95% CI; 19.629.5) had an open wound (n=76), 58.0% (95% CI; 52.3-66.5) (n=181) had healed, and 7.37% were lost to follow-up (n=23). The SEWSS and WIfI classifications were related to major amputation, healing, and death. Regarding the Texas classification, 49% of patients had a penetrating wound to bone or joint (Texas 3), with or without infection. 65.3% of major amputations and 78.6% of deaths occurred in patients with ischemia. The SEWSS cut-off point for major amputation was 20. Conclusions: knowing local data allows organizing resources to improve patient care.

Impacto del manejo multidisciplinario del pie diabético

Objetivo: Estudiar el efecto del manejo multidisciplinario (MMD) de úlcera de PD (UPD) en un Hospital de Chile durante el período 2017-2020. Materiales y Métodos: Estudio comparativo, observacional y retrospectivo, se analizó una base de datos disociada compuesta por 111 pacientes atendidos en el periodo 2017-2020 y se comparó con los datos de 121 pacientes con UPD atendidos en el mismo Hospital sin MMD en periodo 1998-2005. Para los estudios analíticos se usó prueba de Chi cuadrado, prueba exacta de Fisher, U de Mann Whitney y Kruskal Wallis. Resultados: La tasa de reamputaciones mayores con MMD fue de un 2,7%, el 91,2% de los pacientes atendidos con MMD lograron mejorar la condición clínica de la herida, sin embargo, en pandemia por SARCOV-2 la mejoría se redujo a un 78,2%. La tasa de cicatrización completa de la herida con MMD fue de 77,8% v/s 31,4% sin MMD (p < 0,0001) y la tasa de reamputación general sin MMD fue de 47,1% v/s 12,6% con MMD (< 0,0001). La recidiva fue de un 11,7% con MMD v/s 100% a los cuatro años sin MMD (p < 0,0001). Discusión y Conclusión: Observamos que el MMD de la UPD logra mejores tasas de efectividad de la intervención que pacientes sin MMD, mostrándose mejores tasas de cicatrización de la herida, tasa de reamputación mayor, y tasa de recidiva. Por lo tanto, un MMD podría contribuir, significativamente, al rescate de la extremidad afectada.

Objective: To assess the effect of a multidisciplinary approach on patients with diabetic foot ulcer (DFU) in a Hospital in Chile from 2017 to 2020. Material and Method: The study is observational, comparative, and retrospective. The data from 111 patients were analyzed anonymously during 2017-2020. It was compared with old data from a group of121 patients treated in the same hospital but without a multidisciplinary approach. To gather the data the Chi-square test, Fisher's exact test, the U of Mann Whitney, and the Kruskal Wallis were used. Results: It was found that the rate of major re-amputations in patients undergoing treatment with a multidisciplinary approach was 2.7%. Furthermore, 91.2% of patients treated with a multidisciplinary approach improved the clinical condition of the wound. However, During the SARCOV-2 pandemic, the improvement rate was reduced to 78.2%. The complete wound healing rate was 77.8% in patients treated with a multidisciplinary approach versus 31.4% without a multidisciplinary approach (p < 0.0001). The overall re-amputation rate on patients without a multidisciplinary approach was 47.1% versus 12.6% on patients with a multidisciplinary approach (< 0.0001). The recurrence rate was 11.7% in patients with a multidisciplinary approach versus 100% in patients without a multidisciplinary approach (p < 0.0001). Conclusion: We observed finally, we observed that a multidisciplinary approach helped the DFU patients to achieve better intervention effectiveness rates, showing better rates of wound healing, higher re-amputation rate, and recurrence rate. Therefore, a multidisciplinary approach could contribute significantly to the improvement of the affected limb.

Heberprot-P® en el tratamiento de trauma vascular distal / Heberprot-P® in the treatment of distal vascular trauma

Introducción: Los traumatismos constituyen causa frecuente de consulta. Entre sus localizaciones más comunes se encuentran las extremidades inferiores. El Heberprot-P® resulta un factor de crecimiento epidérmico que se ha utilizado durante más de una década para la cicatrización de las úlceras del pie diabético con excelentes resultados. Ampliar su utilización a otras patologías, incluso de etiología traumática, permitiría expandir las posibilidades terapéuticas para la cicatrización de las heridas. Objetivo: Exponer el resultado de la aplicación del Heberprot-P® en una amputación transtarsiana en un paciente portador de un trauma vascular distal. Presentación del caso: Paciente masculino de 23 años con antecedentes de salud. Luego de traumatismo por accidente de tránsito presentó fractura de huesos del metatarso y la sección total de la arteria pedia del pie izquierdo, lo cual provocó una gangrena húmeda de la extremidad. Por este motivo se realizó una amputación transtarsiana del pie. Se usó el Heberprot-P® como terapia para acortar el tiempo de cicatrización. Conclusiones: El Heberprot-P® resultó útil para la evolución de la herida como consecuencia de un trauma vascular, al evitar una amputación mayor, acelerar el proceso de cicatrización y conservar una extremidad funcional, lo que demostró que puede constituir una terapia eficaz para las heridas de difícil cicatrización, independientemente de su etiología(AU)

Introduction: Trauma is a frequent cause of consultation. Among its most common locations are the lower extremities. Heberprot-P® is an epidermal growth factor that has been used for more than a decade for the healing of diabetic foot ulcers with excellent results. Extending its use to other pathologies, including traumatic etiology ones, would expand the therapeutic possibilities for wound healing. Objective: To present the result of the application of Heberprot-P® in a Chopart´s amputation in a patient with distal vascular trauma. Case presentation: A 23-year-old male patient with a health history. After trauma from a traffic accident, he presented a fracture of the bones of the metatarsus and the whole section of the left foot´s pedis artery, which caused a wet gangrene of the extremity. For this reason, a Chopart´s amputation of the foot was performed. Heberprot-P® was used as therapy to shorten healing time. Conclusions: Heberprot-P® was useful for wound evolution as a result of vascular trauma, avoiding major amputation, accelerating the healing process and preserving a functional limb, which showed that it can be an effective therapy for wounds that are difficult to heal, regardless of their etiology(AU)

Structural Design and Optimization of Cushioning Insole with Variable Stiffness / 医用生物力学

Objective An X-shaped cushioning insole with variable stiffness was designed to explore its effects on plantar pressure and internal stress of diabetic patients with toe amputation. Methods Based on CT images, the feet-calf finite element model of diabetic patients with toe amputation was established, and the insole was divided into different areas according to distribution characteristics of the planter pressure. The three-dimensional (3D) printed cushioning insole with an X-shaped sandwich structure was designed. The modulus of the sandwichstructure was changed by changing thickness of the sandwich structure panel. For simulation analysis, the divided area was filled with the X-shaped sandwich structure with different modulus. Results The peak plantar pressure of diabetic patients with toe amputation was in calcaneal region, and the combined insoles with 1. 2 mpanel thickness in toe area, 1. 4 mm panel thickness in metatarsal area, 2. 0 mm panel thickness in middle area and 1. 6 mm panel thickness in heel area had the best decompression effect. Compared with bare feet, the peak pressure in heel area of the insole, the peak pressure in phalangeal head area and the stress in plantar softissues were reduced by 40. 18% , 31. 7% , and 50. 44% , respectively. Conclusions The 3D printed insoles with variable stiffness can effectively reduce surface pressure and internal stress of the sole and reduce probability of the 2nd toe amputation

A Case Report of a Patient who Achieved Recovery of Walking Independence with the Adjustment of the Prosthesis after Bilateral Leg Amputation and Spinal Cord Injury / The Japanese Journal of Rehabilitation Medicine

This report describes a case of an amputee with a lumber spinal cord injury who successfully recovered ambulation with the use of prosthesis.A 30-year-old man with schizophrenia underwent amputation of the lower legs and concurrently developed lumbar spinal cord injury from of a suicide attempt. After the treatment of stump plasty and posterior fusion, the patient was transferred to our facility. Lower-extremity prostheses for both legs were fitted, and orthostatic training was commenced following admission. During the initial evaluation, the patient could not maintain a stable standing position because of weakness in the hip extensor muscle. An inflexion angle of the prosthesis was set to 0° to extend the knee joint and achieve standing stability. Appropriate adjustments of the prosthesis were made as required, specifically addressing the paraplegia caused by his lumbar spinal cord injury. Thus, the patient successfully regained ambulation with the treatment.Recovering walking independence after bilateral lower leg amputations or paraplegia caused by lumber spinal cord injury is not uncommon. However, this case is unique in that the muscle weakness caused by lumbar spinal cord injury presented unforeseen difficulties for the patient to achieve ambulation, which is not ordinarily observed in amputation rehabilitation cases. No similar cases have been reported in which patients concurrently suffered from both these conditions in Japan；therefore, this case is extremely rare.

The Osseous Pathology of Purpura Fulminans in a TwoYear-Old Child: A Case Report

@#Purpura fulminans (PF) is a severe clinical manifestation of Neisseria meningitides infection that is associated with high mortality rates in children. Survivors are frequently left with debilitating musculoskeletal sequelae. There is a paucity of reports on the musculoskeletal pathology of purpura fulminans. We report on a 2-year-old boy with purpura fulminans due to meningococcemia. The child developed distal gangrene in both the upper and lower limbs. Amputations were done for both lower limbs. Histological examination of the amputated specimens showed an inflammatory process and features of osteonecrosis. The latest follow-up at the age of 6 years showed a right knee valgus due to asymmetrical growth arrest of the proximal tibia. PF and its complications are challenging to treat and may require a multidisciplinary approach to improve patient’s functional ability.

AIM: To investigate the protective effect of "DuZhong-DangGui" (DZ-DG) on the knee tissue of rats with osteoarthritis (OA) and its regulation role on NLPR3 inflammasome. METHODS: Twenty-four SPF male SD rats, eighteen rats were randomly selected to establish OA model by anteri- or cruciate ligament amputation (ACLT) method, and rats were divided into control group, OA model group, DZ-DG group and positive drug group, 6 in each group, treatment for 8 weeks. The peripheral blood were collected, ELISA was used to detect the levels of IL-1β, IL-6, IL-18, and TNF-α; cartilage tissue of knee joint were collected, HE staining was used to observe pathology changes, OARSI staining was used to observe cartilage calcification and preform quantitative OARSI scoring; immunohistochemistry and TUNEL staining were used to detect the contents of Caspase1 and Collagen II and the number of apoptosis in the tissue, respectively, and western blot was used to detect the protein expressions of matrix metalloproteinase-13 (MMP-13), tissue inhibitor of metalloproteinase-1 (TIMP-1), p53, p21, NLPR3, apoptosis-associated speck-like protein containing a CARD (ASC) and Pro-Caspase-1. RESULTS: Compared to control group, OA model group rats serum levels of IL-1β, IL-6, IL-18, and TNF - α significantly increased (P<0.01), OARSI scores significantly increased (P<0.01), chondrocyte apoptosis was increased (P<0.01), Caspase-1 content and MMP-13, p53, p21, NLPR3, ASC, Pro-Caspase-1 protein expressions significantly increased (P <0.01), while Collagen II content and TIMP-1 protein expression significantly decreased (P<0.01). Compared with the OA model group, DZ-DG group and positive drug group rats serum levels of IL-1β, IL-6, IL -18 and TNF - α significantly decreased (P< 0.05), chondrocyte apoptosis were significantly decreased (P<0.01), Caspase1 content, MMP-13, p53, NLPR3, Pro-Caspase-1 significantly decreased (P< 0.05), Collagen Ⅱ content and TIMP- 1 protein expression (P<0.01); DZ-DG group rats protein expression of p21 and ASC were decreased (P<0.01). CONCLUSION: The DZ-DG have protection role on cartilage of OA rats, its effect may related to mediation of NLPR3/ASC/Pro-Caspase-1 pathway, to decrease of IL-1β, and inhibition of cell apoptosis.

A Case of Thromboembolism and Deep Venous Thrombosis after Transfemoral Amputation with Short Stump / The Japanese Journal of Rehabilitation Medicine

An 82-year-old patient underwent a left transfemoral amputation due to a malignant soft tissue tumor. He developed symptoms of chest pain and hypoxia on the 32nd day after the operation. These symptoms were caused by deep venous thrombosis (DVT) of the stump and acute pulmonary thromboembolism (PTE), for which he was treated with anticoagulant therapy. Shortly after treatment he could resume a rehabilitation therapy. Patients with a lower extremity amputation have a higher risk of developing a DVT because of immobility and increased venous pooling in the residual limb. Even with a short stump as in this case, it is important to actively train the range of motion of the joint and try to prevent DVT.

Satisfaction of Patients with Above-the-knee Amputation following Periprosthetic Joint Infection / 中山大学学报(医学科学版)

ObjectiveThe purpose of this study was to evaluate the functional outcomes and satisfaction in periprosthetic knee infection patients after above-the-knee amputation （AKA）. MethodsA review was performed in 13 patients who underwent AKA due to periprosthetic knee infection from October 2010 to August 2022， there were 7 females and 6 males with the median age of 69 （45~ 73） years. The mean number of surgical procedures between primary total knee arthroplasty and AKA was 2.9 times （range： 1 ~ 6）. Patients were segregated into non-elderly group （including patients <65 years old） and elderly group （involving patients ≥65 years old）. Functional outcomes were evaluated by SF-12 and Barthel activities daily living index （Barthel ADL index）. Patient satisfaction was accomplished through a questionnaire. ResultsFour patients died within 6 months after the amputation. Three patients received surgical procedures for recurrent infections after AKA. In the remaining 9 patients，the median time from AKA to the final follow-up was 4.2 （1.9~8.2） years， three patients received surgical procedures for recurrent infections after AKA. Patients in non-elderly group showed better functional outcomes than elderly patients after AKA （both P<0.05）. All patients in non-elderly group were fitted with a prosthesis. Whereas， elderly patients reported a better satisfaction after AKA than young patients. ConclusionYoung PJI patients seemed to have better function and ambulatory ability with high expectation and demand， which made them feel less satisfied about AKA. Meanwhile，despite poor function outcomes due to the less healthy physical condition， the alleviation of financial and psychological burdens resulting from reinfections and multiple surgeries and the less demand in function and daily activities made elderly patients have a good satisfaction after AKA.

Animal experimental study on the effects of different levels of amputation on cardiovascular system / 生物医学工程学杂志

Vascular injury resulting from lower limb amputation leads to the redistribution of blood flow and changes in vascular terminal resistance, which can affect the cardiovascular system. However, there was no clear understanding of how different amputation levels affect the cardiovascular system in animal experiments. Therefore, this study established two animal models of above-knee amputation (AKA) and below-knee amputation (BKA) to explore the effects of different amputation levels on the cardiovascular system through blood and histopathological examinations. The results showed that amputation caused pathological changes in the cardiovascular system of animals, including endothelial injury, inflammation, and angiosclerosis. The degree of cardiovascular injury was higher in the AKA group than in the BKA group. This study sheds light on the internal mechanisms of amputation's impact on the cardiovascular system. Based on the amputation level of patients, the findings recommend more comprehensive and targeted monitoring after surgery and necessary interventions to prevent cardiovascular diseases.

Mechanosensitive Ion Channel TMEM63A Gangs Up with Local Macrophages to Modulate Chronic Post-amputation Pain / 神经科学通报·英文版

Post-amputation pain causes great suffering to amputees, but still no effective drugs are available due to its elusive mechanisms. Our previous clinical studies found that surgical removal or radiofrequency treatment of the neuroma at the axotomized nerve stump effectively relieves the phantom pain afflicting patients after amputation. This indicated an essential role of the residual nerve stump in the formation of chronic post-amputation pain (CPAP). However, the molecular mechanism by which the residual nerve stump or neuroma is involved and regulates CPAP is still a mystery. In this study, we found that nociceptors expressed the mechanosensitive ion channel TMEM63A and macrophages infiltrated into the dorsal root ganglion (DRG) neurons worked synergistically to promote CPAP. Histology and qRT-PCR showed that TMEM63A was mainly expressed in mechanical pain-producing non-peptidergic nociceptors in the DRG, and the expression of TMEM63A increased significantly both in the neuroma from amputated patients and the DRG in a mouse model of tibial nerve transfer (TNT). Behavioral tests showed that the mechanical, heat, and cold sensitivity were not affected in the Tmem63a-/- mice in the naïve state, suggesting the basal pain was not affected. In the inflammatory and post-amputation state, the mechanical allodynia but not the heat hyperalgesia or cold allodynia was significantly decreased in Tmem63a-/- mice. Further study showed that there was severe neuronal injury and macrophage infiltration in the DRG, tibial nerve, residual stump, and the neuroma-like structure of the TNT mouse model, Consistent with this, expression of the pro-inflammatory cytokines TNF-α, IL-6, and IL-1β all increased dramatically in the DRG. Interestingly, the deletion of Tmem63a significantly reduced the macrophage infiltration in the DRG but not in the tibial nerve stump. Furthermore, the ablation of macrophages significantly reduced both the expression of Tmem63a and the mechanical allodynia in the TNT mouse model, indicating an interaction between nociceptors and macrophages, and that these two factors gang up together to regulate the formation of CPAP. This provides a new insight into the mechanisms underlying CPAP and potential drug targets its treatment.

Introducción: La rodilla es la región anatómica donde asientan la mayor cantidad de tumores benignos y malignos que afectan el esqueleto humano, entre ellos se encuentra el tumor de células gigantes. Objetivo: Conocer un paciente con un tumor de células gigantes que sufrió transformación maligna. Caso clínico: Paciente, masculino de 28 años de edad, blanco sin antecedentes mórbidos de salud, que acudió a la consulta externa de la especialidad de Ortopedia y Traumatología por presentar desde hace dos años una tumoración dolorosa a nivel de la rodilla que en los últimos dos meses ha aumentado de tamaño. Se realizaron exámenes imagenológicos mediante radiografía simple, tomografía axial computarizada e imagen de resonancia magnética, además de toma de biopsia incisional para confirmar el diagnóstico. Al analizar los resultados de los exámenes anteriores el equipo multidisciplinario decidió la amputación de la extremidad. Conclusiones: El tumor de células gigantes es una enfermedad que se presenta con mayor frecuencia desde la tercera a quinta décadas de la vida, sus complicaciones principales son la recidiva, las metástasis pulmonares y la transformación maligna. Por lo general, los enfermos con esta última complicación necesitan de procedimientos como la amputación de la extremidad.

Introduction: The knee is the anatomical region where the largest number of benign and malignant tumors that affect the human skeleton settle, among them is the giant cell tumor. Objective: To present a patient with a giant cell tumor that underwent malignant transformation. Clinical case: A 28-year-old white male with no morbid health history, who attended the Orthopedics and Traumatology outpatient clinic for presenting a tumor accompanied by pain at the level of the right knee. It appeared two years ago, but has increased in size rapidly in the last two months. Imaging tests were performed using plain radiography, computed tomography, and magnetic resonance imaging, as well as incisional biopsy to confirm the diagnosis. After analyzing the results of the previous examinations, the multidisciplinary team decided to amputate the limb. Conclusions: The giant cell tumor is an entity that occurs most frequently from the third to fifth decades of life; its main complications are recurrence, lung metastases and malignant transformation. In general, patients with this last complication need procedures such as amputation of the limb.
