Objective: To assess the presence of tibial bone tunnel enlargement after surgical reconstruction of the anterior cruciate ligament using quadruple graft of the flexor tendons and correlate the functional results in their presence. Methods: The studied lasted six months and included 25 patients, with ages ranging from 18 to 43 years old. Assessment was based on radiographs taken immediately postoperatively and at the third and sixth month of follow up in the anterior cruciate ligament reconstruction. Reconstruction of ligaments was performed with tendon grafts of the semitendinosus and gracilis muscle fixated in the femur with transverse metal screw and in the tibia with interference screws. Patients were evaluated objectively by tests ligament, graded from zero to four crosses and subjectively by the Lysholm method preoperative and after sixth month follow up. Results: Significant increase in the tunnels diameters were observed, 20.56% for radiographs in the anteroposterior view, 26.48% in profile view and 23.22% in computed tomography. Descriptive statistics showed significant improvement in subjective and objective clinical parameters. Conclusions: The bone tunnel enlargement is a phenomenon found in the first months after surgical reconstruction of the anterior cruciate ligament and it has no implications on clinical outcomes in the short term. Level of Evidence II, Prospective Study.

Objective: The objective of this study was to conduct a comparative analysis on isokinetic strength assessments between field and indoor male professional soccer players and correlate the findings with the higher levels of injury risk described in the literature. Methods: We analyzed 16 field soccer players and 15 indoor soccer players. All these professionals were male. Isokinetic muscle strength assessments were made on their knees. Results: The mean weight was 81.81 kg for field soccer and 80.33 kg for indoor soccer. The right and left peak extensor torque left and right for field soccer and indoor soccer were, respectively, 302.50 and 313.31 Nm and 265.20 and 279.80 Nm, and for flexors, 178 and 184.88 Nm and 158.27 and 154 Nm. The peak torque rates according to body weight for the left and right extensors for field soccer and indoor soccer were, respectively, 3.84 and 3.7 Nm/kg

Foram avaliados vinte e um atletas não profissionais (vinte e um ombros) no período de Fevereiro de 1999 a Março de 2002 com idade media de 26,63 anos portadores de instabilidade antero-inferior traumática. Todos foram submetidos ao tratamento cirúrgico pela tecnica de Bankart com âncoras. O retensionamento capsuloligamentar foi realizado quando o sinal do sulco foi detectado ao exame físico ou durante o ato cirúrgico. Segundo os critérios de Rowe et al.(20), obteve-se quinze resultados excelentes, três bons, dois regulares e um ruim. No pós-operatório, a média da rotações interna, utilizando o nível vertebral como parâmetro foi de T12, rotação externa de 27,19 graus e a abdução media de 166,90 graus, o teste do sulco foi positivo em um (4,76%) paciente e houve recidiva em dois (9,52%). O retorno às atividades esportivas deu-se em 16 atletas (76,19%). Um dos principais fatores relacionados ao abandono e à reabilitação parcial foram o medo de recorrência da dor residual e instabilidade.

The peak torque rates according to body weight for the left and right extensors for field soccer and indoor soccer were, respectively, 3.84 and 3.7 Nm/kg and 3.32 and 3.52 Nm/kg, and for flexors, 2.17 and 2.26 Nm/kg and 1.98 and 1.93 Nm/kg. The balance relationships between flexors and extensors on the right and left sides for field soccer and indoor soccer were, respectively, 59.81 and 59.44% and 60.47% and 54.80%. The relationships for extensors between the right and left sides for field soccer and indoor soccer were, respectively, 11.44 and 9.20%, and for the flexors, 7.31 and 8.80%. Conclusions: In accordance with international parameters, comparative analysis on isokinetic strength assessments between field and indoor male professional soccer players before the season showed that there was muscle balance and low probability of injury. There were no statistically significant differences in the parameters analyzed between the players of the two types of soccer.

To assess the presence of tibial bone tunnel enlargement after surgery to reconstruct the anterior cruciate ligament using quadruple flexor tendon grafts, and to propose a new technique for its measurement. Methods: The study involved 25 patients aged 18-43 years over a six-month period. The assessment was based on radiographs taken immediately postoperatively and in the third and sixth months of evolution after operations to reconstruct the anterior cruciate ligament using grafts from the tendons of the semitendinosus and gracilis muscles, fixed in the femur with a transverse metal screw and in the tibia with an interference screw. The radiographs were evaluated in terms of the relative value between the diameter of the tunnel and the bone, both at 2 cm below the medial tibial condyle. Results: There were significant increases in tunnel diameters: 20.56% for radiographs in anteroposterior view and 26.48% in lateral view. Enlargement was present in 48% of anteroposterior and lateral radiographs, but was present in both views in only 16% of the cases. Conclusions: Bone tunnel enlargement is a phenomenon found in the first months after surgery to reconstruct the anterior cruciate ligament. The measurement technique proposed in this study was sufficient to detect it.

RESUMOO objetivo do estudo foi avaliar a osteotomia calcaneana de deslizamento medial de Koutsogiannis modificada, sob parâ-metros clínicos e radiográficos. Entre janeiro de 1997 e abril de 2001, vinte e nove pés de dezenove pacientes portadores de pé plano valgo flexível idiopático, com idade média de 11,36 anos, foram submetidos ao procedimento de Koutsogiannis modificado pela varização da extremidade deslizada, com um seguimento médio de dezesseis meses. A cirurgia foi indicada para pacientes com sintomas de dor e fadiga e portadores de deformidade. Clinicamente, dezessete pacientes referiram estar sem dor e dezesseis não apresentaram deformidade residual, sendo notada a correção da deformidade do retropé. Obteve-se 9,36 em média na análise dos resultados subjetivos pós-operatórios, cuja graduação era de 0-10. Dois maus resultados de dor e persistência da deformidade foram atribuídos a portadores de hiperfrouxidão ligamentar, com deformidade grave pré-operatória. O estudo radiográfico revelou, na incidência lateral, decréscimo dos valores médios pré-operatórios dos ângulos talocalcaneano e talo-primeiro metatarso de 29,7 e 11,33 graus para valores pós-operatórios de 23,05 e 7,76 graus respectivamente. Na incidência antero-posterior notou-se decréscimo do valor médio do ângulo talocalcaneano de 36,39 para 35,42 graus. Concluiu-se que o procedimento de Koutsogiannis mostrou-se eficaz para o tratamento de pacientes de dez a treze anos, portadores de pé plano valgo flexível idiopático leve e moderado, apresentando melhoria estética, alívio sintomático e melhora radiográfica.Descritores: Descritores: Descritores: Descritores: Descritores: Pé Plano; Cirurgia; Clacâneo; Osteotomia.

Manifesta-se em crianças após a bipedação pela queda do arco plantar longitudinal medial, cabeça do tálus proeminente medial e plantarmente, valgismo do retropé e supinação do antepé (23,10) . Embora, apenas 3% dos pacientes detectados na infância tornar-se-ão dolorosos e incapacitantes na vida adulta, um grande contingente apresenta-se no limiar da normalidade, podendo tornar-se insuficientes e dolorosos quando submetidos à carga (7) . Quando o pé plano postural é submetido ao peso corporal, o calcâneo prona abaixo do tálus e sua extremidade anterior roda lateral e dorsalmente, enquanto a cabeça do tálus move-se medial e plantarmente. Os ligamentos calcaneonavicular plantar e interósseo talocalcaneano alongam-se permitindo a eversão do retropé e a abdução do navicular, que move-se juntamente com o antepé, levando o eixo gravitacional para o primeiro raio. A persistência desta postura determina a contratura do tendão calcâneo, que por sua vez, inclina o calcâne...
