Resumo: | Introduction: The anterior cruciate ligament is one of the main ligaments of the knee, often more susceptible to injuries due to its central position and its vital role in stabilizing this joint. The strength of the quadriceps plays a crucial role, with impact absorption function, helping to reduce load. Objective: To evaluate the volume and strength of the quadriceps muscle before and after reconstruction of the anterior cruciate ligament of the knee, their correlation and which variables predict pre- and postoperative muscle strength. Method: Prospective cohort of 37 patients evaluated preoperatively and 4 months after the operation, using magnetic resonance imaging and isokinetic dynamometry. The measurements of the limb undergoing the operation were compared to the contralateral limb as a control. Result: The volume of the quadriceps muscle was 65.2+13.4cm3 before and 63.4+15.9 cm3 after, significantly lower in the control at both moments, with a reduction of 3.0cm3 (4.1%) in the pre and 7.8 cm3 post (12.0%). Muscle strength was 105.5+29.9N/m before and 100.9+28.6N/m after, significantly lower in the operated limb (126.4+28.2N/m and 129.6+27.6N /m, p<0.001). This reduction was similar in the 2 evaluation moments, on average of 17.5N/m (16.3%) in the pre and 22.8N/m (22.5%) in the post. The loss of strength was greater than the loss of muscle volume, with muscle volume and time of anterior cruciate ligament injury being the main determinants of muscle strength in the pre-op. The strength in the post was mainly determined by that in the pre. Conclusion: The loss of muscle strength was 4 times greater than the loss of volume pre-operatively and 2 times greater post-operatively, indicating the beginning of recovery 4 months post-operatively. |

A força do quadríceps desempenha papel crucial, com função de absorção de impacto, auxiliando na redução de carga. Objetivo: Avaliar o volume e a força do músculo quadríceps antes e após a reconstrução do ligamento cruzado anterior do joelho, sua correlação e quais as variáveis preditivas da força muscular pré e pós-operatória. Método: Coorte prospectiva de 37 pacientes avaliados no pré-operatório e com 4 meses após a operação, por meio de ressonância magnética e dinamometria isocinética. As medidas do membro submetido à operação foram comparadas ao membro contralateral como controle. Resultado: O volume do músculo quadríceps foi de 65,2+13,4cm3 antes e de 63,4+15,9 cm3 após, significativamente menor no controle nos 2 momentos, com redução de 3,0cm3 (4,1%) no pré e 7,8 cm3 no pós (12,0%). A força muscular foi de 105,5+29,9N/m antes e de 100,9+28,6N/m após, significativamente menor no membro operado (126,4+28,2N/m e 129,6+27,6N/m, p<0,001). Esta redução foi semelhante nos 2 momentos de avaliação, em média de 17,5N/m (16,3%) no pré e de 22,8N/m (22,5%) no pós. A perda de força foi maior que a perda de volume muscular, sendo que o volume muscular e o tempo da lesão do ligamento cruzado anterior foram os principais determinantes da força muscular no pré. A força no pós foi determinada principalmente pela do pré. Conclusão: A perda de força muscular foi 4 vezes maior que a perda de volume no pré e 2 vezes maior no pós, indicando início da recuperação com 4 meses no pós-operatório.SciELO PreprintsSciELO PreprintsSciELO Preprints2024-04-17info:eu-repo/semantics/preprintinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://preprints.scielo.org/index.php/scielo/preprint/view/847110.1590/SciELOPreprints.8471porhttps://preprints.scielo.org/index.php/scielo/article/view/8471/15854Copyright (c) 2024 André Luis Menezes Schwansee Thiele, Edilson Schwansee Thiele , Luis Fernando Menezes Schwansee Thiele , Fernando Issamu Tabushi , Paulo Afonso Nunes Nassif , Luiz Martins Collaço, Jose Fernando Polanski , Jurandir Marcondes Ribas Filhohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessThiele, André Luis Menezes SchwanseeThiele , Edilson SchwanseeThiele , Luis Fernando Menezes SchwanseeTabushi , Fernando IssamuNassif , Paulo Afonso NunesCollaço, Luiz MartinsPolanski , Jose FernandoRibas Filho, Jurandir Marcondesreponame:SciELO Preprintsinstname:Scientific Electronic Library Online (SCIELO)instacron:SCI2024-04-17T14:32:19Zoai:ops.preprints.scielo.org:preprint/8471Servidor de preprintshttps://preprints.scielo.org/index.php/scieloONGhttps://preprints.scielo.org/index.php/scielo/oaiscielo.submission@scielo.orgopendoar:2024-04-17T14:32:19SciELO Preprints - Scientific Electronic Library Online (SCIELO)false |
