Lysholm knee score vid bedömning av knäfunktion 20 år efter främre korsbandsskada : Analys av begreppsvaliditet, samtidig validitet, prediktiv validitet, och förändring över tid.Karlsson, Clara, Spännargård, Mira January 2019 (has links)
Introduktion: Efter en korsbandsskada är det av vikt att utvärdera knäfunktionen och följa hur den förändras över tid. Det görs oftast med skattningsformulär, som Lysholm knee score, och fysiska tester. Idag saknas det forskning om validiteten för Lysholm knee score lång tid efter skada. Syftet med studien var att undersöka mätegenskaper för Lysholm knee score vid test av knäfunktion 20 år efter främre korsbandsskada. Metod: Undersökningen gjordes på insamlad data från 70 personer som drabbats av korsbandsskada för mer än 20 år sedan (23±2 år). Materialet var mätt vid tre olika tillfällen, vilket var 2 år, 6-10 år samt 20 år efter skada och bestod av Lysholm knee score, KOOS, KT1000, one leg hop, vertical jump och the side hop test. I studien analyserades begreppsvaliditet, samtidig validitet, prediktiv validitet samt förändring över tid. Pearson’s test användes för test av korrelation, en enkel linjär regression för att undersöka prediktiv validitet och reapeted ANOVA för förändring över tid. Resultat: Resultatet visade att begreppsvaliditeten hade obetydlig korrelation mellan Lysholm knee score och de funktionella knätesterna. Den samtidiga validiteten visade på en stark korrelation för KOOS-symtom och en svag korrelation för KOOS-smärta. Den prediktiva validiteten visade att variationen av Lysholm 20 år senare till viss del kan förklaras av skattningen av Lysholm 2 år efter skadan vilket visade på att den har en prediktiv förmåga. Vid undersökning av förändring över tid av Lysholm knee score visade resultatet att funktionen förändrades till det bättre mellan första och andra mättillfället (p=1.06), medan det försämrades fram till det tredje mättillfället (p<0.001). Konklusion: Lysholm knee score är ett formulär som fångar upp förändring över tid och som till viss del kan predicera hur man skattar den upplevda knäfunktionen över en längre tid. I praktiken bör det användas med flera knäfunktionstester för det ska täcka flera dimensioner av knäfunktion.

CHANGES IN LONGITUDINALLY ASSESSED BIOMECHANICAL PARAMETERS RELATED TO INCREASED RISK OF ANTERIOR CRUCIATE LIGAMENT (ACL) INJURIES IN ADOLESCENT FEMALE AND MALE ATHLETESFord, Kevin Ray 01 January 2009 (has links)
Females suffer anterior cruciate ligament (ACL) injuries at a 2 to 10-fold greater rate compared to male athletes participating in similar sports. Altered movement patterns and inadequate knee stiffness are two interrelated factors that may increase ACL injury risk. Onset of these neuromuscular risk factors may coincide with the rapid adolescent growth that results in the divergence of a multitude of neuromuscular parameters between sexes. The overall purpose of this dissertation was to determine if neuromuscular ACL injury risk factors in female athletes increase following rapid growth and development compared to males. Male and female athletes were tested with three-dimensional motion analysis techniques during a drop vertical jump over two consecutive years to determine if ACL injury risk factors increased. Pubertal females showed a significant longitudinal increase in knee abduction angle compared to post-pubertal females and both male groups. The increase in knee abduction angle appeared to remain consistent, as the post pubertal female cohort had greater overall knee abduction compared to post-pubertal males. Similar results were found with a greater magnitude of knee abduction moment in post-pubertal females compared to males. Males and females increased ankle, knee and hip active stiffness from the first to second year of testing. Ankle and hip stiffness were increased significantly more in the pubertal group compared to post-pubertal. Sex and maturational group differences were found in hip and ankle joint stiffness. Post-pubertal males had significantly greater hip stiffness than the other groups (even when normalized to body mass). This indicates that post-pubertal males utilized a different neuromuscular strategy during landing. Males had a significantly greater increase from year to year in vertical jump height compared to females. Vertical jump height is often related to a measure of whole body power and indicates that males had a significant neuromuscular spurt compared to females. Early puberty appears to be a critical phase related to the divergence of increased ACL injury risk factors. Injury prevention programs that focus on neuromuscular training may be beneficial to help address the development of ACL injury risk factors that occur in female athletes during maturation.

Protocolo de captação, processamento e transplante de enxertos osteocondrais homólogos a fresco na articulação do joelho / Protocol of procurement, processing and transplantation of fresh osteochondral allografts in the knee jointTirico, Luís Eduardo Passarelli 07 April 2015 (has links)
O tratamento das lesões condrais e osteocondrais do joelho em pacientes jovens ainda permanece um desafio para os médicos ortopedistas. As técnicas de reparo destas lesões atualmente disponíveis no Brasil, como desbridamento, microfraturas e transplante osteocondral autólogo são insuficientes nos tratamentos das lesões condrais e osteocondrais maiores do que 4 cm2. O transplante osteocondral homólogo a fresco (TOF) na articulação do joelho vem sendo usado em outros países com excelentes resultados. Até o presente momento não existem relatos da utilização desta técnica no Brasil, fato que dificulta o tratamento de pacientes jovens ativos que necessitam de reparo biológico. Foram incluídos neste estudo oito pacientes de 15 a 45 anos portadores de lesões osteocondrais maiores que 4 cm2. Os enxertos a fresco foram obtidos de doadores de órgãos, sendo a articulação do joelho captada sem violação da cápsula articular e transportada ao Banco de Tecidos para processamento. O pareamento doador e receptor foi realizado conforme o tamanho, a localização e a prioridade em lista de espera de acordo com os tecidos captados, sendo os mesmos armazenados no meio de preservação Ham F-12 - GIBCO com glutamax (Invitrogen, Life Technologies, Estados Unidos) e com antibióticos. O procedimento cirúrgico foi realizado pelas técnicas de cilindro osteocondral e de superfície, sendo fixados quando necessário. Os pacientes foram avaliados através dos questionários de IKDC objetivo, IKDC subjetivo, KOOS e índice de Merle D\'Aubigne e Postel modificado. Foram realizados oito TOFs de março a outubro de 2012. A média de idade dos pacientes transplantados foi de 30,1 anos (17- 44 anos) e a média da área transplantada foi de 10,6 cm2 (4,6 - 22,4 cm2). O intervalo médio em dias entre captação e transplante foi de 15,3 (14 - 16 dias) e o número médio de cirurgias prévias ao TOF foi de 2 cirurgias (0-4 cirurgias). A pontuação na escala de IKDC objetiva no pré-operatório foi B em 12%, C em 25% e D em 63% dos pacientes; e 12% A e 88% B aos 18 meses de pós-operatório. A média da pontuação da escala IKDC subjetiva pré-operatória foi de 31,99 ± 13,4 e de 81,84 ± 9,25 em 18 meses de pós-operatório, e da escala KOOS pré-operatória foi de 46,8 ± 20,9 e de 89,58 ± 7,06 em 18 meses de pós-operatório, com melhora significativa ao longo do tempo (p < 0,01) pela análise da variância. A média da pontuação pelo índice de Merle D\'Aubigne e Postel modificado foi de 8,75 ± 2,25 no pré-operatório e de 16,75 ± 2,19 em 18 meses de pós-operatório. O resultado do teste de Friedman para amostras não-paramétricas demonstrou melhora significativa ao longo do tempo (p < 0,01). A padronização da captação, processamento e transplante de enxertos osteocondrais a fresco na articulação do joelho depende de um banco de tecidos altamente especializado e leva a excelentes resultados no tratamento de lesões osteocondrais grandes, sendo atualmente uma boa alternativa de tratamento biológico para pacientes jovens no Brasil / Treatment of chondral and osteochondral lesions of the knee in young patients is still a challenge for Orthopedic Surgeons. The techniques available nowadays in Brazil, as debridement, microfracture and autologous osteochondral transplantation are insufficient for the treatment of chondral and osteochondral lesions larger than 4 cm2. Fresh osteochondral allografts on the knee joint have been used in other countries with great success. Until the present days there are no reports of the utilization of this technique in Brazil, a fact that creates boundaries for the treatment of young active patients that need cartilage repair treatment. Eight patients with age ranging from 15 to 45 years old and osteochondral lesions larger than 4 cm2 were included in this study. Fresh grafts were obtained from organ donors and the knee joint was harvest without violation of synovium capsule and then was transported to the tissue bank for processing. Donor and receptor tissue matching occurred according to size, localization and priority on waiting list and tissue was preserved in Ham F-12 - GIBCO media with glutamax (Invitrogen, Life Technologies, United States) and antibiotics. Surgical procedure was achieved with osteochondral plugs or shell techniques, with additional fixation when needed. Patients were evaluated with IKDC objective, IKDC subjective, KOOS and modified Merle D\'Aubigne-Postel outcome scores. Eight fresh osteochondral allografts were performed from march to october, 2012. The average age was 30.1 years old (17-44) and mean graft surface area was 10.6 cm2 (4.6 - 22.4 cm2). Average time from harvest to transplantation was 15.3 days (14-16 days) and mean number of previous surgical procedures was 2 (0 - 4 procedures). Pre-operative objective IKDC score was B in 12%, C in 25% and D in 63% and was A in 12% and B in 88% in 18 months follow-up. Pre-operative IKDC subjective and KOOS score were 31.99 ± 13.4 and 46.8 ± 20.9; and in 18 months follow-up were 81.84 ± 9.25 and 89.58 ± 7.06, respectively, with a significant increase along time on variance analysis (p < 0.01). Pre-operative mean modified Merle D\'Aubigne-Postel scores were 8.75 ± 2.25 and 16.75 ± 2.19 in 18 months follow-up. Non-parametric Friedman test analysis showed a significant progression in follow-up (p < 0.01). Standards of procurement, processing and utilization of fresh osteochondral allografts in the knee joint relay on a high specialized tissue bank and promote excellent results on the treatment of large osteochondral lesions, being a good alternative of a biologic repair for young patients in Brazil

Reparo meniscal em crianças e adolescentes : uma revisão sistemática de resultadosFerrari, Márcio Balbinotti January 2018 (has links)
OBJETIVO: Realizar uma revisão sistemática da literatura existente, a fim de analisar os resultados após o reparo meniscal na população pediátrica. MÉTODOS: Uma revisão sistemática foi realizada de acordo com as diretrizes PRISMA usando os Bancos de Dados de Análise Sistemática Cochrane, Registro Central Cochrane de ensaios controlados, MEDLINE Ovid e MEDLINE PubMed. Os critérios de inclusão foram os seguintes: estudos que relatam os resultados do reparo meniscal em pacientes com 18 anos ou menos, com um seguimento médio mínimo de 12 meses, idiomas português, espanhol ou inglês e estudos humanos incluindo 10 ou mais pacientes. RESULTADOS: Nossa pesquisa identificou 2534 títulos individuais. Após a aplicação dos critérios de inclusão e exclusão, foram incluídos oito estudos, avaliando 287 pacientes com lesões meniscais reparadas. Sete estudos foram classificados como nível de evidência IV e um nível III. O escore médio MINORS foi de 8,6 ± 1,4. O reparo meniscal incluiu todas as zonas meniscais e padrões de lesões. A lesão do ligamento cruzado anterior foi a lesão associada mais comum. As técnicas “inside-out” e “all-inside” foram predominantemente relatadas. A maioria dos pacientes relatou resultados bons a excelentes e teve sinais clínicos de cicatrização meniscal; as meniscectomias após reparação meniscal foram realizadas em apenas 44 casos. CONCLUSÃO: Lesões meniscais em pediatria não são incomuns. O reparo desta lesão foi associado com resultados bons a excelentes na maioria dos pacientes, independentemente do padrão de lesão, zona ou técnica. As complicações relatadas foram mínimas, no entanto, são necessários estudos de maior qualidade para confirmar os achados desta revisão sistemática. NÍVEL DE EVIDÊNCIA: Nivel IV, revisão sistemática de estudos nível III e nível IV. / PURPOSE: To perform a systematic review of existing literature in order to analyze outcomes after meniscal repair in the pediatric population. METHODS: A systematic review was performed according to PRISMA guidelines using the Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials, MEDLINE Ovid, and MEDLINE PubMed databases. Inclusion criteria were as follows: studies reporting the outcomes of meniscal repair in patients 18 years old or younger, with a minimum mean follow-up of 12 months, Portuguese, Spanish or English languages, and human studies including 10 or more patients. RESULTS: Our search identified 2534 individual titles. After application of the inclusion and exclusion criteria, 8 studies were included, evaluating 287 patients with repaired meniscal tears. Seven studies were classified as level of evidence IV and one level III. The mean MINORS score was 8.6 ± 1.4. Meniscal repair included all meniscal zones and tear patterns. Anterior cruciate ligament tear was the most common associated injury. The all-inside and inside-out techniques were predominantly reported. The majority of the patients reported good to excellent outcomes and had clinical signals of meniscal healing; meniscectomies following meniscal repair were performed in just 44 cases. CONCLUSION: Meniscal tears in pediatrics are not uncommon. Repairs of this injury were associated with good to excellent outcomes in most patients, regardless of the injury pattern, zone or technique. Reported complications were minimal, however, higher quality studies are needed to confirm the findings of this systematic review. LEVEL OF EVIDENCE: Level IV, systematic review of Level III and Level IV studies.

The Multi-Ligament Quality of Life Questionnaire (ML-QOL): Development and Preliminary Testing of Measurement Properties in Patients with Multi-Ligament Knee InjuriesChahal, Jaskarndip 21 November 2013 (has links)
Despite the existence of numerous knee-joint specific patient-reported outcome measures, the content contained within such instruments does not completely capture the spectrum of injury and impairments experienced by multi-ligament knee injured patients. Based on this shortcoming, the overall objective of the current study was to develop, and to test the reliability and validity of a novel disease-specific quality of life instrument for patients with multi-ligament knee injuries. The World Health Organization’s International Classification of Functioning, Disability, and Health was used to guide content development. Using a mixed methods approach (surveys, patient focus groups, expert interviews), the final Multi-ligament Quality of Life (MLQOL) instrument was comprised of 52 items distributed over 4 domains. This instrument demonstrated excellent content validity, test-retest reliability, and construct validity. Future work will evaluate the responsiveness of the MLQOL and will implement its use in randomized trials.

Tidigt insatt hög-intensiv vadmuskelträning efter knäplastikoperation : Effekt på vadmuskelstyrka, självvald gånghastighet och självskattad symptom, smärta, ADL funktion samt livskvalité / High-intensive calf muscle training in the early post-operative phase following knee arthroplasty : Effect on calf muscle strength, self-selected walking speed and self-rated symptom, pain, ADL function as well as quality of lifeSvantesson, Charlotte January 2014 (has links)
Syfte Syftet med föreliggande studie var att undersöka genomförbarheten av en hög-intensiv träningsintervention efter knäplastikoperation samt hur knäplastikopererade personers självvalda gånghastighet, maximal vadmuskelstyrka, vadmuskeluthållighet och självupplevda symptom, smärta, ADL funktion och hälsorelaterad livskvalité påverkas av tidigt insatt hög-intensiv styrketräning av vadmuskulaturen. Metod Femton forskningspersoner randomiserades till en träningsgrupp (n=7), som utförde hemträningsprogram i form av hög-intensiv vadmuskelträning samt till en kontrollgrupp (n=8) som utförde samma rehabiliteringsprogram som träningsgruppen utan hög-intensiv vadmuskelträning. En testprocedur genomfördes 3 respektive 12 veckor efter knäplastikoperationen. Självvald gånghastighet mättes genom ett 30 meters gångtest, vadmuskeluthållighet mättes med ett standardiserat tåhävningstest på ett ben, maximal isometrisk vadmuskelstyrka mättes med hjälp av en isometrisk dynamometer och självskattad symptom, smärta, ADL funktion och livskvalité utvärderades genom Knee injury Osteoarthritis Outcome Score (KOOS). Resultat Denna studie påvisar viss problematik med följsamheten i träningsregim för båda grupperna. Båda gruppernas sammanslagna resultat uppvisade signikant förbättrad självvald gånghastighet, maximal vadmuskelstyrka och uthållighet över tid. Trots detta ökade träningsgruppen den självvalda gånghastigheten signifikant mer än kontrollgruppen över tid. Träningsgruppen hade även mindre besvär på grund av smärta 12 veckor efter operationen. Båda gruppernas sammanslagna resultat förbättrades över tid gällande deras egen skattning av symptom, smärta, ADL funktion och livskvalité. Däremot förbättrade träningsgruppen alla variabler signifikant medan det för kontrollgruppen endast var livskvalitén som förbättrades signifikant över tid. Konklusion Tidigt insatt hög-intensiv vadmuskelträning efter knäplastikoperation är genomförbart och kan ha en viss positiv effekt på personens egen upplevelse av symtom, smärta, funktion och hälsorelaterad livskvalité. Självvald gånghastighet förefaller öka mer vid tidigt insatt hög-intensiv vadmuskelträning efter nio veckors träning jämfört med samma rehabiliteringsprogram utan hög-intensiv vadmuskelträning. / Aim The aim of this study was to determine the feasibility of a high-intensive exercise intervention following a knee arthroplasty, and also to evaluate possible effects on self-selected walking speed, calf muscle strength and self-rated symptoms, pain, ADL function and quality of life after high-intensive calf muscle training in an early post-operative phase. Method Fifteen participants were randomized into an exercise group (n=7), who performed a home-exercise program, consisting of high-intensive calf muscle exercise, and into a control group (n=8) who performed the same rehabilitation program but without the high-intensive calf muscle training. A test procedure was conducted after 3 and 12 weeks following the knee arthroplasty. Self-selected walking speed was measured by a 30 meter walking test, calf muscle endurance training was measured with a standardized one-leg heel-rise test, maximal isometric calf muscle strength was measured with an isometric dynamometer, and self-rated symptom, pain, ADL function and quality of life were evaluated with Knee injury Osteoarthritis Outcome Score (KOOS). Results There were problems with adherence to exercise regimes in both groups. The results of both groups demonstrated improved self-selected walking speed, calf muscle endurance and maximal isometric calf muscle strength over time. However, the exercise group increased self-selected walking speed more than the control group. The exercise group reported fewer disorders due to pain 12 weeks after surgery. The results of both groups showed improved self-rated symptoms, pain, ADL function and quality of life over time, however, the exercise group improved all these variables significantly, while the control group significantly improved the quality of life aspect. Conclusions Early initiated high-intensive calf-muscle training following a knee artroplasthy is feasible and may have positive effects on self-rated symptoms, pain, ADL function and quality of life. Also, self-selected walking speed increased more with early initiated high-intensive calf muscle training after nine weeks when compared to the same rehabilitation program without high-intensive calf muscle training.

Donor and receptor tissue matching occurred according to size, localization and priority on waiting list and tissue was preserved in Ham F-12 - GIBCO media with glutamax (Invitrogen, Life Technologies, United States) and antibiotics. Surgical procedure was achieved with osteochondral plugs or shell techniques, with additional fixation when needed. Patients were evaluated with IKDC objective, IKDC subjective, KOOS and modified Merle D\'Aubigne-Postel outcome scores. Eight fresh osteochondral allografts were performed from march to october, 2012. The average age was 30.1 years old (17-44) and mean graft surface area was 10.6 cm2 (4.6 - 22.4 cm2). Average time from harvest to transplantation was 15.3 days (14-16 days) and mean number of previous surgical procedures was 2 (0 - 4 procedures). Pre-operative objective IKDC score was B in 12%, C in 25% and D in 63% and was A in 12% and B in 88% in 18 months follow-up. Pre-operative IKDC subjective and KOOS score were 31.99 ± 13.4 and 46.8 ± 20.9; and in 18 months follow-up were 81.84 ± 9.25 and 89.58 ± 7.06, respectively, with a significant increase along time on variance analysis (p < 0.01). Pre-operative mean modified Merle D\'Aubigne-Postel scores were 8.75 ± 2.25 and 16.75 ± 2.19 in 18 months follow-up. Non-parametric Friedman test analysis showed a significant progression in follow-up (p < 0.01). Standards of procurement, processing and utilization of fresh osteochondral allografts in the knee joint relay on a high specialized tissue bank and promote excellent results on the treatment of large osteochondral lesions, being a good alternative of a biologic repair for young patients in Brazil
