Calculation of the Minimal Important Clinical Difference of the Lysholm and IKDC Scores After Anterior Cruciate Ligament Reconstruction.

Objective To calculate the minimal important clinical difference (MICD) value for the Lysholm and International Knee Documentation Committee (IKDC) scores in a sample of patients submitted to anterior cruciate ligament reconstruction. Methods Primary, observational, retrospective, analytical study of participants submitted to anterior cruciate ligament reconstruction from March 2019 to December 2020 by the same surgeon, with a minimum follow-up of 6 months, analysis of knee function in the pre- and postoperative period by the Lysholm and IKDC scores, and answer to an anchor question at 6 months postoperatively for the calculation of the MICD of each score. Results A total of 59 patients participated in the study, with a mean age of 27.1 ± 5.7 years old. In the comparison between pre- and postoperative scores of all groups, there was an increase in values with statistical significance after intervention. The MICD was 5.5 for the Lysholm score, and the MICD value for the IKDC score could not be determined. Conclusion For the Lysholm score, the calculation of the MICD value by the anchor question method in the sample evaluated was 5.5. It was not possible to determine the value of the MICD for the IKDC score.

Resumo Objetivo Calcular o valor da mínima diferença clinicamente importante (MDCI) para os escores de Lysholm e International Knee Documentation Commitee (IKDC) na amostra de pacientes submetidos a reconstrução de ligamento cruzado anterior. Métodos Estudo primário, observacional, retrospectivo, analítico, de participantes submetidos a reconstrução do ligamento cruzado anterior no período de março de 2019 a dezembro de 2020, pelo mesmo cirurgião, com seguimento mínimo de 6 meses, análise da função do joelho no período pré e pós-operatório pelos escores de Lysholm e IKDC, e resposta a uma pergunta âncora aos 6 meses de seguimento pós-operatório, para o MDCI de cada escore. Resultados Participaram do estudo 59 pacientes, com média de idade de 27,1 ± 5,7 anos. Na comparação dos escores pré- e pós-operatórios de todos os grupos, observa-se aumento dos valores com significância estatística após a intervenção. A MDCI foi de 5,5 para o escore de Lysholm, não tendo sido possível determinar o valor para o IKDC. Conclusão O cálculo do valor da MDCI pelo método da pergunta âncora, na amostra avaliada, foi de 5,5 para o escore de Lysholm. Não foi possível determinar o valor da MDCI para o IKDC.

Tendinopatia patelar: resultados tardios do tratamento cirúrgico / Patellar tendinopathy: late-stage results from surgical treatment

Avaliar os resultados tardios do tratamento cirúrgico na tendinopatia patelar (TP) com o uso do escore Visa (Victorian Institute of Sport Tendon Study Group) e o método de Verheyden. Métodos: Estudo retrospectivo que avaliou os resultados pós-operatórios de 12 pacientes, ou 14 joelhos, entre julho de 2002 e fevereiro de 2011. Foram incluídos os pacientes com tendinopatia patelar refratários ao tratamento conservador e que não apresentavam outras lesões cirúrgicas concomitantes. Pacientes que não foram devidamente acompanhados no período pós-operatório foram excluídos. Resultados: Pelo método de Verheyden, nove pacientes foram considerados muito bons, dois bons e um ruim. Em relação ao Visa, a média foi de 92,4 pontos, com apenas dois pacientes abaixo de 70 pontos (66 e 55 pontos). Conclusão: O tratamento cirúrgico da tendinopatia patelar, quando corretamente indicado, tem bons resultados em longo prazo.

To evaluate the late-stage results from surgical treatment of patellar tendinopathy (PT), using the Visa score (Victorian Institute of Sport Tendon Study Group) and the Verheyden method. METHODS: This was a retrospective study in which the postoperative results from 12 patients (14 knees) who were operated between July 2002 and February 2011 were evaluated. The patients included in the study presented patellar tendinopathy that was refractory to conservative treatment, without any other concomitant lesions. Patients who were not properly followed up during the postoperative period were excluded. RESULTS: Using the Verheyden method, nine patients were considered to have very good results, two had good results and one had poor results. In relation to Visa, the mean was 92.4 points and only two patients had scores less than 70 points (66 and 55 points). CONCLUSION: When surgical treatment for patellar tendinopathy is correctly indicated, it has good long-term results.

Lesão da artéria poplítea durante a reconstrução do ligamento cruzado posterior / Popliteal artery injury during posterior cruciate ligament reconstruction

Comparative study between physical examination, electroneuromyography and ultrasonography in diagnosing carpal tunnel syndrome

Objective: To evaluate the sensitivity of electromyography and ultrasonography in diagnosing carpal tunnel syndrome (CTS), in comparison with physical examination, which is considered to be the gold standard. Methods: In this cross-sectional study, the medical files of 56 patients with 70 hands affected by CTS who were attended between March 2010 and June 2012 were reviewed. The study included patients with a clinical diagnosis of CTS. The sensitivity of the complementary examinations was analyzed and compared with physical examination. Results: Nocturnal symptoms were found in 96.4%, thenar atrophy in 62.5% and abnormal sense of touch in 50%. The sensitivities found were: ultrasonography, 67.1% (95% CI: 55.7%–78.6%); an association of physical examination tests, 95.7% (95% CI: 90.0%–100%); and electromyography, 98.6% (95% CI: 95.7%–100%). The presence of atrophy, abnormalities of the sense of touch and longer-duration symptoms increased the sensitivity of ultrasonography and physical examination. Conclusion: The sensitivity of ultrasonography for CTS was lower than that of electromyography and physical examination...

Objetivo: Avaliar a sensibilidade da eletroneuromiografia (ENMG) e da ultrassonografia (USN) no diagnóstico de síndrome do túnel do carpo (STC) comparada com a do exame físico, considerado padrão-ouro. Métodos: Estudo seccional pela análise de prontuários de 56 pacientes com 70 mãos acometidas com STC entre março de 2010 e junho de 2012. A sensibilidade dos exames complementares foi analisada e comparada com a do exame físico. Resultados: Constataram-se sintomas noturnos em 96,4%, hipotrofia tenar em 62,5% e alteracão do tato em 50%. A sensibilidade da USG foi de 67,1% (95% IC, 55,7%-78,6%); a da associacão dos testes do exame físico, de 95,7 (95% IC, 90,0%-100%); e a da ENMG, de 98,6% (95% IC, 95,7%-100%). A presenca de hipotrofia, de alteracões no tato e o maior tempo dos sintomas aumentaram a sensibilidade da USG e do exame físico. Conclusão: A sensibilidade da USG para a STC foi inferior à da ENMG e à do exame físico...

Osteoma osteoide no osso ilíaco: relato de dois casos / Osteoid osteoma in the iliac bone: report on two cases

O osteoma osteoide é um tumor benigno do osso que se apresenta geralmente com dor noturna em adultos jovens, aliviada por repouso e salicilatos. Pode acometer qualquer osso, mas sua ocorrência no ilíaco é infrequente. Os autores descrevem dois casos de osteoma osteoide intramedular, localizado junto à articulação sacroilíaca, com sintomas que simulavam dor ciática e cujo diagnóstico se deu de forma tardia, apesar de o exame radiológico inicial mostrar lesão esclerótica em ambos os casos. O diagnóstico foi ratificado por tomografia computadorizada e o tratamento proposto foi a ressecção em bloco da lesão, com excisão do nidus. O diagnóstico definitivo foi confirmado pelo exame histopatológico. No seguimento de longo prazo, ambos estão assintomáticos e observou-se completa remodelação óssea no sítio cirúrgico. Os autores enfatizam as características típicas do tumor, a localização não usual, o diagnóstico diferencial e o tratamento.

Osteoid osteoma is a benign bone tumor that generally presents with nighttime pain among young adults and is relieved by rest and salicylates. It can affect any bone, but occurrences in the iliac are unusual. The authors describe two cases of intramedullary osteoid osteoma next to the sacroiliac joint, with symptoms that simulated sciatic pain. The cases were diagnosed late, although the initial radiographs showed sclerotic lesions in both cases. The diagnosis was confirmed by means of CT scan and the nidus was excised surgically through en bloc resection. The definitive diagnosis was given by means of histopathological examination. Over long-term follow-up, both cases remained asymptomatic and complete bone remodeling at the surgical site was observed. The authors highlight the typical characteristics of the tumor, the unusual location, the differential diagnosis and the treatment.
