ABSTRACT
ABSTRACT Objective: To correlate clinical and intraoperative findings with the postoperative evaluation of two-stage bicruciate knee ligament reconstruction. Methods: The study was conducted with 25 patients (20 men and 05 women) with mean age of 32.3 years, mean body mass index (BMI) of 26.2, and mean lesion duration of 18.3 months. The treatment consisted of an Inlay reconstruction of the posterior cruciate ligament (PCL) followed by the anterior cruciate ligament (ACL) reconstruction, at least 3 months after the first surgical procedure. Four patients required additional procedures: patellar tendon (02), medial collateral ligament (MCL) (02). Results: With an average follow-up of 24.8 months, 60% of the patients scored zero or + at the posterior drawer test, while 40% scored ++; 60% of patients were evaluated as good/excellent according to the Lysholm scale. Only one patient reached the pre-injury Tegner activity level. Injury duration had a negative influence on functional limitation, vitality, and mental health (SF-36). Conclusion: Although two-stage bicruciate knee ligament reconstruction improved knee stability and self-assessment, 96% of patients did not recover their pre-injury state. In the 36-item short form survey (SF-36), injury duration was inversely correlated with self-assessment of functional capacity, physical limitation, vitality, and mental health. Level of Evidence II, retrospective study.
RESUMO Objetivo: Correlacionar os achados clínicos e intraoperatórios com a avaliação pós-operatória da reconstrução ligamentar bicruzada do joelho em dois tempos. Métodos: 25 pacientes (20 homens e 05 mulheres), média de idade de 32,3 anos, IMC médio de 26,2, tempo médio da lesão de 18,3 meses. O tratamento foi iniciado com a reconstrução INLAY do LCP e, após o intervalo mínimo de 3 meses, foi realizada a reconstrução do LCA. Procedimentos adicionais em 04 pacientes - tendão patelar (02), LCM (02). Resultados: com seguimento médio de 24,8 meses, o teste de gaveta posterior foi classificado como zero ou + em 60% dos pacientes avaliados e 40% como ++. 60% dos pacientes avaliados como bons / excelentes (Lysholm). Apenas um paciente atingiu o nível de atividade Tegner pré-lesão. A tempo da lesão influenciou negativamente os parâmetros de limitação do funcionamento físico dos aspectos físicos, vitalidade e saúde mental (SF-36). Conclusão: a reconstrução bicruzado do joelho, em dois tempos, melhorou a estabilidade do joelho e a avaliação subjetiva, mas 96% dos pacientes não recuperaram o estado pré-lesão. O tempo de lesão apresentou correlação estatística inversa com a avaliação subjetiva da capacidade funcional, limitação dos aspectos físicos, vitalidade e saúde mental no escore S-36. Nível de Evidência II, Estudo retrospective.
ABSTRACT
Objective: To assess the functional balance of the knee after bicruciate reconstruction and its correlation with clinical score. Methods: 14 patients (11 men and three women), mean age 29.9±7.65 years, mean BMI 26.2±2.51 kg/m2 underwent surgical reconstruction of the Posterior Cruciate Ligament (PCL) and Anterior Cruciate Ligament (ACL) in two stages, with a mean interval of 3 months between procedures. With a mean follow-up period of 27.33 months, the isokinetic knee analysis was performed at 60°/s and 180°/s and the Lysholm and Tegner scores were applied. Results: The Lysholm score was 86.8±11.1 points and the Tegner score showed a deficit of 30% compared to pre-injury level. In isokinetic evaluation, the deficit of the operated quadriceps average torque was 17.05% at 60°/s and 12.16% at 180°/s, while the average flexor torque deficit was 3.43% at 60°/s and 5.82% at 180°/s. Although it was observed torque deficit between members, there were no statistical differences regarding the functional balance between hamstrings and quadriceps. Conclusion: Although the results of isokinetic evaluation has shown a functional balance of the knee (flexor-extensor), which may have contributed to the good subjective Lysholm score in the bicruciate two-stage reconstruction, two-stage reconstruction did not restore the pre-injury functional level.
