ABSTRACT

Abstract Purpose: To evaluate the use of platelet-rich plasma in the early stages of healing of traumatic injury of the medial collateral ligament in the knee of rabbits. Methods: Thirty rabbits were subjected to surgical lesion of the medial collateral ligament. Of these, 16 were treated with platelet-rich plasma and 14 with saline (control). After 3 and 6 weeks of treatment, 50% of the animals from each group were sacrificed, and biomechanical tests were performed on the injured ligament to compare the tensile strength between the two groups. Results: Platelet-rich plasma significantly increased the tensile strength of the ligament in the groups treated after3 and 6 weeks. In the group treated with platelet-rich plasma vs. saline, the tensile strength values were 3192.5 ± 189.7 g/f vs. 2851.1 ± 193.1 g/f at3 weeks (p = 0.005) and 5915.6 ± 832.0 g/f vs. 4187.6 ± 512.9 g/f at 6 weeks (p = 0.0001). Conclusion: The use of platelet-rich plasma at the injury site accelerated ligament healing in an animal model, demonstrated by an increase in the tensile strength of the medial collateral ligament.

ABSTRACT

Si bien la mayor parte de las lesiones del ligamento colateral medial (LCM) pueden ser tratados de forma incruenta con buenos resultados, existen situaciones en las cuales el tratamiento quirúrgico es mandatorio. El objetivo fue describir la técnica quirúrgica mínimamente invasiva para la reconstrucción del complejo posteromedial. Materiales y métodos: Diez rodillas cadavéricas fueron evaluadas bajo tres condiciones: estado intacto del LCM, estado seccionado del LCM y estado de reconstrucción del LCM. La evaluación fue realizada en extensión completa y en 20º de flexión, aplicando 10N de valgo. La brecha medial fue medida en radiografías con estrés en valgo para evaluar la traslación en los tres estados diferentes. Resultados: La brecha medial en promedio aumento estadísticamente luego de la sección de las estructuras posteromediales en extensión y a 20 grados de flexión (11 mm y 12,6 vs 3.3 y 3.7 respectivamente p<0.05). Cuando comparamos el valor del estado intacto y luego de la reconstrucción por técnica mínimamente invasiva, no encontramos diferencia estadística tanto en 0° (p:0,56), y en 20° de flexión (p:0,102). La confiabilidad inter-observador demostró un valor kappa de 0.86. Conclusión: Mediante una técnica mínimamente invasiva de reconstrucción del CPM se puede restaurar la estabilidad medial de la rodilla en extensión completa y en 20° de flexión. Nivel de evidencia: IV...


To evaluate if medial knee stability would be restored to the intact state with a minimally invasive posteromedial reconstruction technique. Methods: Ten cadaveric knees were tested under three conditions: intact state, sectioned state and reconstructed state. Medial compartment opening was measured on valgus stress radiographs (mm) made at full extension and at 20º of flexion with a 10-N valgus load (applied with a dynamometer) to assess valgus stability in the intact, sectioned and reconstructed states. Results: The average medial gap statistically increased after sectioning of the posteromedial structures in both extension and 20 degrees of flexion (11 mm and 12.6 mm vs 3.3 mm and 3.7 mm respectively p<0.05). When comparing the value of the intact state and following the minimally invasive reconstruction technique, there was no statistically significant difference at both 0° (p=0.56), and 20° of flexion (p=0.102). Inter-observer reliability showed a kappa value of 0.86. Conclusion: A minimally invasive approach for a medial knee reconstruction restores near-normal medial stability to the knee at full extension and at 20º of flexion. Clinical relevance: Development of minimally invasive techniques will allow medial ligament reconstruction with minimal disruption of the surrounding tissue, potentially leading to less scarring and easier restoration of knee motion post-operatively, with results similar to that obtained with conventional techniques. Level of evidence: IV...

ABSTRACT

CONTEXT AND OBJECTIVE: Electrical stimulation (ES) is widely used to strengthen muscles following ligament and meniscal injuries. The aim of this study was to evaluate the effectiveness of ES for rehabilitation after soft tissue injuries of the knee treated surgically or conservatively. DESIGN AND SETTING: Systematic review at the Brazilian Cochrane Center. METHODS: We searched the Cochrane Central Register of Controlled Trials (2010, Issue 12), Medline (Medical Analysis and Retrieval System Online) via PubMed (1966 to December 2010), Embase (Excerpta Medica database, 1980 to December 2010), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde, 1982 to December 2010), and PEDro (Physiotherapy Evidence Database, 1929 to December 2010). The studies included were randomized controlled trials using ES to increase muscle strength for rehabilitation of patients with soft tissue injuries of the knee. Two authors independently evaluated studies for inclusion and performed data extraction and methodological quality assessment. RESULTS: Seventeen studies evaluating ES after anterior cruciate ligament reconstruction and two studies evaluating ES after meniscectomy were included. There was a statistically significant improvement in quadriceps strength through ES (mean difference, MD: -32.7; 95 percent confidence interval, CI: -39.92 to -25.48; n = 56) and in functional outcomes (MD -7; -12.78 to -1.22; n = 43) six to eight weeks after surgical reconstruction of the anterior cruciate ligament. CONCLUSION: There is evidence that ES coupled with conventional rehabilitation exercises may be effective in improving muscle strength and function two months after surgery.


CONTEXTO E OBJETIVO: A estimulação elétrica (ES) é amplamente utilizada para fortalecimento muscular após lesões ligamentares ou meniscais do joelho. O objetivo deste estudo foi avaliar a efetividade da ES na reabilitação de lesões de tecidos moles do joelho tratadas de forma cirúrgica ou conservadora. TIPO DE ESTUDO E LOCAL: Revisão sistemática no Centro Cochrane do Brasil. MÉTODOS: Realizamos uma busca no Cochrane Central Register of Controlled Trials (2010, Issue 12), Medline (Medical Analysis and Retrieval System Online) via PubMed (1966 até dezembro 2010), Embase (Excerpta Medica Database, de 1980 até dezembro 2010), Lilacs (Literatura Latino-Americana e do Caribe em Ciências da Saúde, de 1982 até dezembro de 2010), and PEDro (Physiotherapy Evidence Database, de 1929 até dezembro de 2010). Os estudos incluídos foram ensaios clínicos randomizados que utilizaram a ES com o objetivo de aumento de força muscular na reabilitação de pacientes com lesões de tecidos moles. Dois autores avaliaram os estudos para inclusão de forma independente e realizaram a extração de dados e avaliação da qualidade metodológica. RESULTADOS: Dezessete estudos incluídos utilizaram a ES após a reconstrução do ligamento cruzado anterior e dois estudos após meniscectomia. Houve melhora estatisticamente significante na força do quadríceps através da ES (diferença média, MD -32.7; 95 por cento intervalo de confiança, IC -39.92 to -25.48; n = 56) e nos desfechos funcionais (MD -7; -12.78 to -1.22; n = 43), seis a oito semanas após cirurgia de reconstrução do ligamento cruzado anterior. CONCLUSÃO: Há evidências de que a ES combinada a exercícios de reabilitação convencional pode ser efetiva na melhora da força muscular e função dois meses após cirurgia.

ABSTRACT

Radiografia e ultrassonografia foram avaliadas como técnicas no diagnóstico por imagem na ruptura do ligamento cruzado cranial (LCCr) em cães. Vinte e cinco cães foram submetidos à radiografia e ultrassonografia e seus resultados foram comparados aos obtidos por artrotomia (teste padrão ouro). O exame radiográfico diagnosticou corretamente a lesão em 84 por cento (21/25) dos casos, mas 16 por cento (4/25) apresentaram resultado falso-negativo. O exame ultrassonográfico foi capaz de diagnosticar acertadamente 76 por cento (19/25) dos casos, e sugeriu a ruptura do LCCr nos 24 por cento (6/25) restantes, apresentando 100 por cento de resultados positivos. Concluiu-se que a radiografia e a ultrassonografia são ferramentas valiosas para diagnosticar casos de ruptura do LCCr em cães.


Radiography and ultrasonography were evaluated as tools for diagnosis of the rupture of cranial cruciate ligament (CrCL) in dogs. Twenty-five dogs were submitted to radiographic and ultrasonographic examinations and their results were compared with those obtained by artrotomy (gold standard). Radiography detected the rupture in 84 percent (21/25) of the cases, but 16 percent (4/25) were false-negative. Ultrasonography identified accurately 76 percent (19/25) of the cases and gave a probable diagnosis for the remaining 24 percent (6/25) what means that this technique presented 100 percent of positive results. It was possible to conclude that radiography and ultrasonography are valuable tools for the diagnosis of CrCL rupture in dogs.

ABSTRACT

Avaliou-se por estudo clínico e isocinético o resultado da reconstrução do ligamento cruzado anterior (LCA) com o uso do tendão do quadríceps (TQ). Compararam-se os resultados objetivos da avaliação isocinética com os dados clínicos e de exame físico obtidos com os sistemas de avaliação de Lysholm e do Hospital for Special Surgery Knee Score (HSSKS). Comparou-se a avaliação isocinética do membro operado com a do membro contralateral. Material e métodos: Os pacientes com lesão do LCA foram submetidos à reconstrução pelo mesmo cirurgião, usando técnica cirúrgica artroscópica transtibial com enxerto do tendão do quadríceps. Dos pacientes, 54 foram avaliados em consultório segundo critérios clínicos e 32 realizaram exame isocinético. Resultados: Na escala de Lysholm a média foi de 97,66 pontos e na escala HSSKS, de 94,88 pontos. O torque máximo do quadríceps do lado operado apresenta déficit médio de 12,1por cento, 20,3 por cento e 25,5 por cento nas velocidades de 60°, 180° e 3000/seg, respectivamente. Não houve déficit de f1exão
