ABSTRACT

Objective The objective of the present study is to evaluate the impact evaluate the impact of an institutional protocol on a tertiary hospital for the prevention of venous thromboembolism in 2005 patients submitted to primary total knee arthroplasty (TKA). Methods Data from medical records of patients submitted TKA before ( n = 1,115) and after ( n = 890) the implementation of the institutional protocol, totaling 2,005 patients, were retrospectively reported. Demographics, comorbidities, and outcomes were analyzed. Results There was no significant change in the cases of deep venous thrombosis (DVT) (1.6% versus 2.4%; p = 0.211). There was an increase in cases of pulmonary embolism (PE) (0.2% versus 0.8% p = 0.049). Conclusion Despite the implementation of the prevention protocol, no reduction in the studied events was observed. The small global incidence makes further studies with larger series necessary to confirm or rule out these findings.

Resumo Objetivo O objetivo do presente estudo é avaliar o impacto de um protocolo institucional em um hospital terciário na prevenção do tromboembolismo venoso em 2.005 pacientes submetidos a artroplastia total primária de joelho. Métodos Os dados dos prontuários de pacientes submetidos a artroplastia total do joelho antes (n= 1.115) e após (n= 890) a implantação do protocolo institucional, totalizando 2.005 pacientes, foram relatados retrospectivamente. Dados demográficos, comorbidades e desfechos foram analisados. Resultados Não houve alteração significativa nos casos de trombose venosa profunda (TVP) (1,6% versus 2,4%; p= 0,211). Houve um aumento nos casos de embolia pulmonar (EP) (0,2% versus 0,8%; p= 0,049). Conclusão Apesar da implementação do protocolo de prevenção, não houve redução nos eventos estudados. A pequena incidência global faz com que novos estudos, com séries maiores, sejam necessários para confirmar ou descartar esses achados.

ABSTRACT

OBJECTIVE: To evaluate the contamination rate of hamstring tendon autografts by comparing two different techniques, and to verify whether intraoperative contamination is associated with the development of clinical infection in patients submitted to reconstruction of the anterior cruciate ligament (ACL). METHODS: A total of 110 hamstring tendon autograft ACL reconstructions were performed and divided into two groups: 1-hamstring tendon retraction technique; and 2 - technique maintaining the tibial insertion of the hamstring tendon. During the preparation, two graft fragments were sent for culturing; the harvesting time, the preparation time, and the total surgery time were measured. Twenty-four hours after the surgery, the C-reactive protein was assayed. The clinical outpatient follow-up was performed up to 180 days postoperatively. RESULTS: Although there were two postoperative infections, there was no graft contamination or difference between the groups in relation to the graft preparation time and to the 24-hour postoperative C-reactive protein assessment. The classic technique presented a longer graft harvesting time ( p = 0.038), and there was no statistical difference between the 2 groups regarding the degree of contamination and consequent clinical infection, although 2 patients in group 2 presented with infection, with negative perioperative cultures. CONCLUSION: Based on the results obtained, there was no association between graft contamination and the time or technique of its preparation. In addition, there was also no association between intraoperative contamination and the development of clinical infection, nor was there any sign of an association between the early alteration of C-reactive protein and the onset of infection.

Resumo Objetivo: Avaliar a taxa de contaminação de autoenxerto de tendões flexores comparando duas técnicas e verificar se a contaminação intraoperatória está associada ao desenvolvimento de infecção clínica em pacientes submetidos a reconstrução do ligamento cruzado anterior. Métodos: Foram feitas 110 reconstruções do ligamento cruzado anterior com tendão dos flexores e divididas em dois grupos: 1) técnica com retirada total dos tendões flexores e 2) técnica que manteve a inserção tibial desses tendões. Durante o preparo, dois fragmentos de cada um desses foram enviados para cultura, sendo mensurado o tempo de retirada dos tendões, do preparo dos tendões e total da cirurgia. Com 24 horas de pós-operatório, foi dosada a proteína C reativa. Seguimento clínico ambulatorial foi realizado de forma protocolada até 180 dias de pós-operatório. Resultados: Apesar de terem sido observadas duas infecções pós-operatórias, não houve contaminação dos enxertos nem diferença entre os grupos emrelação ao tempo de preparo dos enxertos e a proteína C reativa com 24 horas de pós-operatório. A técnica clássica apresentou maior tempo de retirada do enxerto (p = 0,038) e não houve diferença estatística entre os dois grupos no que tange ao grau de contaminação e consequente infecção clínica, embora dois pacientes do grupo 2 tenham tido infecção com culturas perioperatórias negativas. Conclusão: Com base nos resultados obtidos, não houve associação entre contaminação do enxerto com o tempo ou a técnica de sua preparação, tampouco entre a contaminação intraoperatória e o desenvolvimento de infecção clínica ou entre alteração precoce da proteína C reativa e o surgimento de infecção.

ABSTRACT

ABSTRACT Objective: Violation of the posterior femoral cortex commonly referred to as posterior wall blowout, can be a devastating intraoperative complication in anterior cruciate ligament reconstruction (ACLR) and can lead to loss of graft fixation or early graft failure. This study describes and analyzes whether the femoral tunnel view test can ensure the integrity of the femoral tunnel during ACLR. Methods: Intraoperative femoral tunnel integrity using the 360º arthroscopic view test was performed in 584 ACLR patients between 2014 and 2016. Posterior wall blowouts were described by their location along the femoral tunnel (i.e., near the aperture or more proximal) and by the depth of the tunnel blowout (<3 mm, 3-5 mm, >5 mm), corresponding to the length of the posterior cortical wall of the violated femoral tunnel. The time spent for the test was measured during ACLR. Complications related to the femoral tunnel view test were also evaluated. Results: The femoral tunnel view test was performed in all 584 patients. In 12 patients (1%), the femoral tunnel presented a posterior cortical blowout that did not extend beyond 3 mm. Only four patients (0.6%) presented posterior wall blowout that extended beyond 5 mm. The time for the test was 40 s (±20 s). No complications related to the test were reported. Conclusion: The femoral tunnel view test is effective for ensuring the integrity of the femoral tunnel during ACL reconstruction, without increasing the surgical time and without an increase in the complications rate. Clinical relevance: The femoral tunnel view test is a quick and straightforward test able to provide an adequate view of the patient's anatomy to ensure tunnel integrity during ACLR.


RESUMO Objetivos: A violação da cortical femoral posterior pode ser complicação intraoperatória devastadora na reconstrução do ligamento cruzado anterior (RLCA), pode levar à perda de fixação ou à falha precoce do enxerto. Este estudo descreve e analisa a capacidade do teste de visualização artroscópica do túnel femoral em evidenciar a integridade de suas paredes durante a RLCA. Métodos: Foram prospectivamente avaliados 584 pacientes elegíveis à RLCA entre 2014 e 2016 quanto à integridade do túnel femoral com o uso do teste de visualização artroscópica. A localização ao longo do túnel femoral e a profundidade da violação no túnel (< 3 mm, 3-5 mm, > 5 mm) foram avaliadas. O tempo para o teste foi medido e a ocorrência de complicações relacionadas ao mesmo também foi analisada. Resultados: Todos os 584 pacientes elegíveis foram submetidos ao teste de visualização do túnel femoral durante a cirurgia artroscópica para RLCA. Em 12 (1%) pacientes, o túnel femoral apresentou perda de integridade da cortical posterior, que não ultrapassou 3 mm. Apenas quatro (0,6%) pacientes apresentaram violação da cortical posterior, que se estendeu para além de 5 mm. O tempo médio dispendido no teste foi de 40 segundos (± 20). Nenhuma complicação realização foi relatada. Conclusão: O teste de visualização do túnel femoral é eficaz para avaliar a integridade desse túnel durante a RLCA, sem aumentar o tempo cirúrgico e sem provocar aumento na taxa de complicações relativas ao procedimento. Relevância Clínica: O teste de visualização artroscópica do túnel femoral é uma técnica simples e rápida, capaz de obter visão adequada da anatomia do paciente, garante a integridade do túnel durante a RLCA.

ABSTRACT

Pigmented villonodular synovitis is a rare proliferative condition of the synovium. Although the condition can present in any joint, the knee is the most commonly affected site. Despite being a benign condition, pigmented villonodular synovitis is often aggressive, with marked extra-articular extension in some cases. Monoarticular involvement occurs in two forms: localized and diffuse. The latter is more common, with a high recurrence rate. There is no standard method of management of this lesion. Open surgery is a classical and effective method for treatment. Arthroscopic synovectomy, however, has gained popularity, and has several advantages over the open technique particularly in exclusively articular cases. The combined approach is suggested in cases with extra-articular involvement. Synovectomy through any approach may prevent secondary osteoarthritis and subsequent joint arthroplasty. Internal irradiation or external beam radiation as an adjuvant treatment to surgical synovectomy appears to decrease the rate of local recurrence in diffuse cases. The authors observed a great heterogeneity in reporting of functional results, and specific conclusions should not be drawn. Each patient should be managed in accordance with his/her particular condition.


A sinovite vilonodular pigmentada é uma rara condição proliferativa da membrana sinovial. Apesar de a doença poder estar presente em qualquer articulação, o joelho é o local mais frequentemente afetado. Ainda que doença benigna, geralmente tem comportamento agressivo, pode ter extensão extra-articular em alguns casos. O acometimento monoarticular ocorre em duas formas: localizada ou difusa. A forma difusa é mais comum e tem alta taxa de recorrência. Não há método padronizado para o manejo dessa lesão. O tratamento cirúrgico aberto é o método clássico e efetivo. A sinovectomia artroscópica, entretanto, tem ganhado popularidade e tem diversas vantagens sobre a técnica aberta, principalmente em casos exclusivamente articulares. A abordagem combinada é sugerida em casos com envolvimento extra-articular. A sinovectomia pode prevenir a osteoartrose secundária e o subsequente tratamento reconstrutivo. A radioterapia usada como tratamento adjuvante à sinovectomia parece diminuir a taxa de recorrência local na forma difusa da doença. Os autores encontraram grande heterogeneidade na forma como os resultados funcionais foram reportados e não se deve chegar a conclusões específicas. Cada paciente deve ser manejado de acordo com suas particularidades.

ABSTRACT

OBJECTIVE: To assess whether there the final range of motion (ROM) results achieved by patients undergoing total knee arthroplasty (TKA) with prosthesis using Medial Pivot design are predictable. METHODS: Between January and August of 2014, 155 patients with primary osteoarthritis of knee who underwent TKA using the prosthesis ADVANCE® Medial Pivot were prospectively assessed. All ROM measures were made and recorded before, during, and after surgery. All patients were clinically assessed preoperatively and postoperatively (15, 45 days, three months, six months, one year, and annually thereafter after surgery); their functional status was assessed using the WOMAC questionnaire. RESULTS: Significant differences (p < 0.001) were observed between the means and medians of ROM in the preoperative when compared with those during the perioperative; the perioperative values, when compared with those after six months postoperative, were also different (p < 0.001). No significant differences were found between the means and medians ROM between the intraoperative period and at the 45-day assessment (ns) and between the means and medians ROM between the preoperative period and at the six-month evaluation (ns). CONCLUSION: The final ROM achieved by patients that underwent TKA with medial pivot prosthesis can be predicted. The perioperative ROM correlates with that at 45 days after surgery. The final ROM is correlated with that of the pre-operative period.


OBJETIVO: Avaliar se há previsibilidade da amplitude de movimentos alcançada por pacientes submetidos a artroplastia total do joelho com prótese que usa desenho medial pivot. MÉTODOS: Entre janeiro e agosto de 2014 foi feita avaliação prospectiva de 155 pacientes com osteoartrose primária do joelho submetidos a artroplastia total do joelho com o uso da prótese Advance® Medial Pivot. Todas as medidas da amplitude de movimentos foram feitas antes, durante e após a cirurgia. Todos os pacientes foram avaliados clinicamente no pré- e pós-operatório (15, 45 dias, três meses, seis meses, um ano e depois anualmente após a cirurgia) para a análise de seu estado funcional. O questionário Western Ontario and McMaster Universities Osteoarthritis Index (Womac) foi usado. RESULTADOS: Diferenças significativas (p < 0,001) foram relatadas entre as médias e medianas da amplitude de movimentos no pré-operatório em comparação com as medidas obtidas no período intraoperatório. As medidas do pré-operatório também se mostraram diferentes quando comparadas com aquelas após seis meses de pós-operatório (p < 0,001). Não foram encontradas diferenças significativas entre as médias e medianas da amplitude de movimento na comparação do intraoperatório e as medidas feitas aos 45 dias (ns) e entre as médias e medianas das medidas pré-operatórias e aquelas observadas aos seis meses (ns). CONCLUSÃO: Há previsibilidade da amplitude de movimentos obtida por pacientes submetidos a artroplastia total do joelho com prótese medial pivot. A amplitude aos 45 dias é semelhante àquela observada nas medidas intraoperatórias. A amplitude final está relacionada à amplitude pré-operatória.

ABSTRACT

Chronic patellar tendon rupture is a rare disabling injury that is technically difficult to repair. The true prevalence of this injury is unknown. Delayed reconstruction of chronic patellar tendon rupture has yielded suboptimal clinical and functional results. Many different surgical methods for reconstruction of chronic patellar tendon injury have been reported. In this report, we present a case with chronic patellar tendon injury that was addressed using a technique that had not previously been described in the literature, through combining procedures that had been described separately. The reconstruction method presented in this article has the advantages of being easy and reproducible, without a requirement of allografts.


A ruptura crônica do tendão patelar é lesão rara e incapacitante e ainda tecnicamente difícil de abordar. A verdadeira prevalência dessa lesão é desconhecida. A reconstrução tardia das rupturas crônicas do tendão patelar apresenta resultados clínicos e funcionais abaixo do ideal. Muitos métodos cirúrgicos diferentes foram relatados para a reconstrução do tendão patelar em lesões crônicas. Neste relato apresentamos um caso com lesão crônica do tendão patelar abordado com técnica até então não descrita na literatura, que combina, todavia, técnicas previamente relatadas. O método de reconstrução presente neste artigo tem a vantagem de ser fácil e reprodutível, sem a necessidade de aloenxertos.

ABSTRACT

A relação causal entre o uso crônico dos bifosfonatos e a ocorrência de fraturas femorais atípicas não tem sido ainda estabelecida. Todavia, sabe-se que o uso crônico dos bifosfonatos tem tido maior relação com fraturas com padrão diferente das clássicas fraturas osteoporóticas. Fraturas atípicas são ainda eventos raros e o benefício do uso dos bifosfonatos ainda é maior na prevenção e no tratamento da osteoporose. Pouco são os estudos que orientam o diagnóstico e a condução dessas fraturas, o que dificulta melhores resultados. Neste relato apresentamos caso de paciente da terceira idade com fratura femoral atípica conduzida segundo orientação da Sociedade Americana para Pesquisa Óssea e Mineral.


The causal relationship between chronic use of bisphosphonates and occurrences of atypical femoral fractures has not yet been established. Nonetheless, it is known that their chronic use is more related to fractures with a pattern differing from that of classical osteoporotic fractures. Atypical fractures are still rare events and the benefit from using bisphosphonates remains greater for prevention and treatment of osteoporosis. There are few studies guiding the diagnosis and management of these fractures, thus making it difficult to achieve better results. In this report, we present the case of an elderly patient with an atypical femoral fracture that was managed in accordance with guidance from the American Society for Bone and Mineral Research.

ABSTRACT

OBJECTIVE: the aim of this study is to evaluate the change in length of hospital stay postoperatively for Total Knee Arthroplasty after using femoral and sciatic nerve block. MATERIALS AND METHODS: the medical records of 287 patients were evaluated, taking into account the number of hours of admission, the percentage and the reason for re-hospitalization within 30 days, as well as associated complications. All patients were divided into two groups according or not to whether they were admitted to ICU or not. During the years 2009 and 2010, isolated spinal anesthesia was the method used in the procedure. From 2011 on, femoral and sciatic nerve blocking was introduced. RESULTS: between the years 2009 and 2012, the average length of stay ranged from 74 hours in 2009 to 75.2 hours in 2010. The average length of stay in 2011 was 56.52 hours and 53.72 hours in 2012, all in the group of patients who did not remain in the ICU postoperatively. In the same period, among those in the group that needed ICU admission, the average length of stay was 138.7 hours in 2009, 90.25 hours in 2010, 79.8 hours in 2011, and 52.91 hours in 2012. During 2009 and 2010, the rate of re-hospitalization was 0%, while in 2011 and 2012, were 3.44% and 1%, respectively. CONCLUSION: according to this study, the use of femoral and sciatic nerve blocking after total knee arthroplasty allowed significant reduction in hospital stay.

Partial tears of the anterior cruciate ligament (ACL) are common and represent 10-27% of the total. The main reasons for attending to cases of non-torn bundles are biomechanical, vascular and proprioceptive. Continued presence of the bundle also serves as protection during the healing process. There is controversy regarding the definition of these injuries, which is based on anatomy, clinical examination, translation measurements, imaging examinations and arthroscopy. The way in which it is treated will depend on the existing laxity and instability. Conservative treatment is optional for cases without instability, with a focus on motor rehabilitation. Surgical treatment is a challenge, since it requires correct positioning of the bone tunnels and conservation of the remnants of the torn bundle. The pivot shift test under anesthesia, the magnetic resonance findings, the previous level and type of sports activity and the arthroscopic appearance and mechanical properties of the remnants will aid the orthopedist in the decision-making process between conservative treatment, surgical treatment with strengthening of the native ACL (selective reconstruction) and classical (anatomical) reconstruction...


Lesões parciais do ligamento cruzado anterior (LCA) são comuns e representam 10%-27% das totais. As principais razões para atenção ao feixe não rompido são biomecânicas, vasculares e proprioceptivas. A permanência do feixe serve ainda de proteção durante o processo cicatricial. A definição dessa lesão é controversa, baseada na anatomia, no exame clínico, na medida da translação, nos exames de imagem e na artroscopia. Seu tratamento vai depender da frouxidão e da instabilidade existentes. O tratamento conservador é opcional para casos sem instabilidade, com enfoque na reabilitação motora. O tratamento cirúrgico é desafiador, pois exige correto posicionamento dos túneis ósseos e conservação dos remanescentes do feixe rompido. O teste do pivot-shift sob anestesia, os achados à ressonância magnética, o nível e o tipo de atividade esportiva prévia e o aspecto artroscópico dos remanescentes e suas propriedades mecânicas auxiliarão o ortopedista no processo decisório entre o tratamento conservador, o tratamento cirúrgico com reforço do LCA nativo (reconstrução seletiva) ou a reconstrução clássica (anatômica)...

ABSTRACT

Objective: the aim of this study is to evaluate the change in length of hospital stay postoperatively for Total Knee Arthroplasty after using femoral and sciatic nerve block. Materials and methods: the medical records of 287 patients were evaluated, taking into account the number of hours of admission, the percentage and the reason for re-hospitalization within 30 days, as well as associated complications. All patients were divided into two groups according or not to whether they were admitted to ICU or not. During the years 2009 and 2010, isolated spinal anesthesia was the method used in the procedure. From 2011 on, femoral and sciatic nerve blocking was introduced. Results: between the years 2009 and 2012, the average length of stay ranged from 74 hours in 2009 to 75.2 hours in 2010. The average length of stay in 2011 was 56.52 hours and 53.72 hours in 2012, all in the group of patients who did not remain in the ICU postoperatively. In the same period, among those in the group that needed ICU admission, the average length of stay was 138.7 hours in 2009, 90.25 hours in 2010, 79.8 hours in 2011, and 52.91 hours in 2012. During 2009 and 2010, the rate of re-hospitalization was 0%, while in 2011 and 2012, were 3.44% and 1%, respectively. Conclusion: according to this study, the use of femoral and sciatic nerve blocking after total knee arthroplasty allowed significant reduction in hospital stay. .


Objetivo: avaliar a mudança no tempo de permanência hospitalar (PH) no pós-operatório de artroplastia total do joelho (ATJ) após a utilização do bloqueio dos nervos femoral e ciático. Métodos: os prontuários de 287 pacientes foram avaliados, levando-se em consideração o número de horas de internação, o percentual e o motivo de reinternação em 30 dias, bem como as complicações associadas, sendo divididos em dois grupos de acordo com a permanência ou não no centro de terapia intensiva (CTI). Durante os anos de 2009 e 2010, a anestesia utilizada para a realização dos procedimentos foi a raquianestesia isolada. A partir de 2011, o bloqueio dos nervos femoral e ciático foi introduzido. Resultados: no período entre 2009 e 2012, o tempo médio de PH variou entre 74 horas, em 2009, e 75,2 horas, em 2010. A PH média em 2011 foi de 56,52 horas e de 53,72 horas em 2012, no grupo de pacientes que não permaneceram no CTI no pós-operatório. No mesmo período, no grupo que precisou de internação no CTI, a PH média foi de 138,7 horas em 2009; 90,25 horas em 2010; 79,8 horas em 2011 e 52,91 horas em 2012. Em 2009 e 2010, a taxa de reinternação foi de 0%, e em 2011 e 2012, 3,44% e 1%, respectivamente. Conclusão: de acordo com este estudo, a utilização do bloqueio dos nervos femoral e ciático após a ATJ permitiu a redução significativa da PH. .

ABSTRACT

Infection after total knee replacement (IATJ) is a rare complication. It is associated with increased morbidity and mortality increasing the final costs. Gram positive coccus and Staphylococcus coagulase-negative and Staphylococcus aureus are the most common isolated germs (>50% of the cases). Conditions related to the patient, to the surgical procedure and even to the post op have been identified as risk factors to IATJ. Many complementary methods together with clinical symptoms are useful to a proper diagnosis. Treatment for IATJ must be individualized but generally is a combination of systemic antibiotic therapy and surgical treatment. Prosthesis exchange in one or two stages is the first choice procedure. Debridement with prosthesis retention is an option in acute cases with stable implants and antibiotic sensible germs.


Infecção após artroplastia total do joelho (IATJ) é complicação incomum. Está associada a aumento da morbimortalidade e dos custos de internação. Cocos gram-positivos, sobretudo Staphylococcus coagulase-negative e Staphylococcus aureus, são os germes mais comumente isolados (> 50% de todos os casos). Condições ligadas ao paciente, ao procedimento cirúrgico e mesmo ao pós-operatório têm sido identificadas como fatores de risco para IATJ. Vários são os métodos complementares que se somam à investigação clínica para o diagnóstico infeccioso e melhor caracterização do quadro. O tratamento para a IATJ deve ser individualizado, mas geralmente envolve a combinação da antibioticoterapia sistêmica com o tratamento cirúrgico. A troca do implante em um ou dois estágios é o procedimento de escolha. Desbridamento com retenção da prótese é opção em casos agudos, com implantes estáveis e com germes sensíveis aos agentes antimicrobianos.

ABSTRACT

OBJETIVO: Apresentar nova técnica de reconstrução do ligamento patelofemoral medial (LPFM) em pacientes com luxação recidivante da patela e avaliar seus resultados clínicos. MÉTODOS: Entre jan/2007 e jan/2008, 23 pacientes foram submetidos à reconstrução do LPFM com enxerto livre de tendão semitendíneo. Após acompanhamento mínimo de 24 meses, 22 pacientes foram avaliados pelos protocolos clínicos de Kujala e de Lysholm. RESULTADOS: O seguimento médio foi de 26,2 meses. Segundo o protocolo de Lysholm, os pacientes apresentaram pontuação média de 53,72 pontos no pré-operatório e 93,36 pontos no pós-operatório (p = 0,000006). Pelo protocolo de Kujala, a pontuação média foi 59,81 pontos no préoperatório e 83,54 pontos no pós-operatório (p = 0,002173). CONCLUSÃO: A reconstrução do ligamento patelofemoral medial pela técnica proposta mostrou excelentes resultados no curto prazo, quando avaliada por protocolos clínicos.


OBJECTIVE: To present a new technique for reconstruction of the medial patellofemoral ligament (MPFL) in patients with recurrent patellar dislocation and to evaluate the clinical findings from this. METHODS: Between January 2007 and January 2008, 23 patients underwent reconstruction of the MPFL with a free graft from the semitendinosus tendon. After a minimum of 244 months of follow-up, 22 patients were evaluated using the Kujala and Lysholm clinical protocols. RESULTS: The mean follow up was 26.2 months. According to the Lysholm protocol, the patients had a mean score of 53.72 points preoperatively and 93.36 points postoperatively (p = 0.000006). According to the Kujala protocol, the mean score was 59.81 points preoperatively and 83.54 points postoperatively (p = 0.002173). CONCLUSION: Reconstruction of the medial patellofemoral ligament using the proposed technique showed excellent results over the short term, when evaluated by means of clinical protocols.

ABSTRACT

UNLABELLED: To compare the rollback of the contact point between the femoral component and the tibial polyethylene as the knee is flexed, in two types of total knee arthroplasty: one that sacrifices and the other that preserves the posterior cruciate ligament (PCL). METHODS: Under fluoroscopy, 36 knees from 32 patients who underwent total knee arthroplasty were evaluated. Using lateral images, the contact points between the femur and the tibial polyethylene with the knee in complete extension and at 90° of flexion were measured, thereby measuring the percentage rollback of the femur in arthroplasties in which the PCL was sacrificed and in those in which it was preserved. RESULTS: The mean percentage rollback of the femur was 13.24% in the cases in which the PCL was sacrificed and 5.75% in the cases in which it was preserved. The difference between these measurements was statistically significant (p = 0.026615). CONCLUSION: In total knee arthroplasty, sacrificing the PCL increased the rollback of the contact point between the femur and tibia as the knee was flexed up to 90°.

ABSTRACT

OBJETIVO: Avaliar se após a artroplastia total do joelho existe correlação entre a altura da patela e a amplitude de movimento (ADM) alcançada pelo paciente após seis meses de pós-operatório. MÉTODOS: Foram avaliados 45 pacientes submetidos a artroplastia total do joelho, todos com, no mínimo, 12 meses de pós-operatório, totalizando 54 joelhos. Sob fluoroscopia, todos os joelhos tiveram suas amplitudes de movimentos (ADM) máximas e mínimas registradas, bem como a altura da patela pelo índice de Blackburne e Peel. Foram avaliadas as duas correlações possíveis: relação entre altura da patela e ADM e altura da patela e a variação de ADM entre o pré e o pós-operatório. RESULTADOS: Foi observada correlação entre altura da patela e ADM no pós-operatório (p = 0,04). Não foi observada correlação entre altura da patela e variação de ADM (p = 0,182). CONCLUSÃO: No pós-operatório da artroplastia total do joelho, quanto mais baixa a patela, pior a ADM.


OBJECTIVE: To evaluate whether, after total knee arthroplasty, there is any correlation between patellar height and range of motion (ROM) achieved by patients six months after the operation. METHODS: Forty-five patients who underwent total knee arthroplasty were assessed at least 12 months after the operation (total of 54 knees). The maximum and minimum ROM of all the knees was recorded under fluoroscopy, along with patellar height according to the Blackburne and Peel ratio. Two possible correlations were evaluated: patellar height and ROM; and patellar height and ROM variation from before to after the operation. RESULTS: A correlation was found between patellar height and postoperative ROM (p = 0.04). There was no correlation between patellar height and ROM variation (p = 0.182). CONCLUSION: After total knee arthroplasty, the lower the patella is, the worse the ROM is.

ABSTRACT

OBJETIVO: Comparar a posteriorização do ponto de contato entre o componente femoral e o polietileno tibial à medida em que o joelho é fletido em dois tipos de artroplastia total do joelho, uma com sacrifício e outra com preservação do ligamento cruzado posterior (LCP). MÉTODOS: Foram analisados, sob fluoroscopia, 36 joelhos de 32 pacientes submetidos a artroplastia total do joelho. Analisando as imagens em perfil, foi medido o ponto de contato do fêmur com o polietileno tibial com o joelho em extensão completa e em 90 graus de flexão, mensurando-se o percentual de "rolamento" posterior do fêmur nas artroplastias em que o ligamento cruzado posterior (LCP) foi sacrificado e naquelas nas quais esse foi preservado. RESULTADOS: O percentual médio de posteriorização do fêmur foi de 13,24 por cento nos casos em que o LCP foi sacrificado e de 5,75 por cento nos casos em que esse foi preservado. A diferença entre essas medidas foi estatisticamente significativa, com p = 0,026615. CONCLUSÃO: Na artroplastia total do joelho, sacrificar o LCP aumenta a translação posterior do ponto de contato entre o fêmur e a tíbia à medida em que o joelho é flexionado até 90 graus.
