Abstract

BACKGROUND AND OBJECTIVES: Patellofemoral pain syndrome is an anterior knee pain (or retropatellar), associated to knee joint stress. The risk factors include musculoskeletal disorders that affect the distribution of forces acting on the knee joint, as in the femoral anteversion. The objective of this study was to verify the relationship between the femoral anteversion angle and the patellofemoral pain syndrome in young women who do not practice regular physical activity.

METHODS: This is a cross-sectional, case-control study. The sample includes 100 women (G1, n=50 - anterior knee pain; G2, n=50 - control group). The instruments applied were the Anterior Knee Pain Score, numerical pain scale, and Craig’s test. The groups were compared using the Student’s t-test, p<0.05 for significant results (GraphPad Prism 8).

RESULTS: The mean age was 21.5±3.45 and 20.9±2.85 years old for G1 and G2, respectively. Mean pain intensity was 4.6±1.97 for G1, with no pain recorded in G2 (p=0.0001). The mean anteversion angle of the femoral neck was 16.2±4.85 degrees in G1 and 15.6±4.87 degrees in G2 (p= 0.566). The average score obtained with the Anterior Knee Pain Score was 81.4±10.46 and 94.8±5.41 points for groups 1 and 2, respectively (p=0.0001).

CONCLUSION: No relationship was found between angulation of the femoral neck and the presence of anterior knee pain, however, a greater functional loss in the group with pain was observed.

JUSTIFICATIVA E OBJETIVOS: A síndrome da dor patelofemoral se manifesta com dor anterior no joelho ou retropatelar, relacionada ao aumento do “stress” articular. Os fatores de risco incluem disfunções musculoesqueléticas que afetem a distribuição de forças na articulação do joelho, como ocorre na anteversão femoral. O objetivo deste estudo foi verificar a relação do ângulo de anteversão femoral com a dor anterior no joelho de mulheres jovens não praticantes de atividade física regular.

MÉTODOS: Estudo transversal, caso-controle. A amostra foi composta por 100 mulheres divididas nos grupos dor anterior no joelho (G1) e controle (G2) cada um com 50 indivíduos. Os instrumentos aplicados foram: o Anterior Knee Pain Score, a escala numérica da dor, e teste de Craig. Os grupos foram comparados entre si pelo teste t de Student, adotando-se p<0,05 para resultados significativos (GraphPad Prism 8).

RESULTADOS: A média de idade foi de 21,5±3,45 e 20,9±2,85 anos para G1 e G2, respectivamente. A intensidade média da dor foi 4,6±1,97 para o G1, não havendo registro de dor no G2 (p=0,0001). A angulação média de anteversão do colo femoral foi de 16,2±4,85 graus no G1 e 15,6±4,87 graus no G2 (p=0,566). Por fim, o escore médio obtido com o Anterior Knee Pain Score foi de 81,4±10,46 e 94,8±5,41 pontos para os grupos 1 e 2, respectivamente (p=0,0001).

CONCLUSÃO: Não foi encontrada relação entre angulação do colo femoral com a presença de dor anterior do joelho, no entanto, observou-se no grupo com dor havia maior perda funcional.
