[en] BACKGROUND: Alterations in the stabilisation system of the patella were considered the main trigger factor of PFPS, but currently the literature contains that maltraking of the patellar in the frontal plane can be caused by poor mechanical hip during performance functional activities. OBJETIVE: evaluate if hip functional alterations may adversely affect to patellofemoral pain syndrome. Also, determinate if a physiotherapy program of muscle strength in the hip can benefit this syndrome. METHODS: The research of the information was taken from the database; PubMed, PEDro, Scopus, CINHAL y Sportdiscuss, during the months of February to April 2016. The methodological quality of the studies was measured with the PEDro scale and the degree of evidence with OCEMB (Center of Evidence -Based Medicine, Oxoford) scale. OUTCOMES: 11 articles fulfilled the inclusion criteria. In 6 of them there was found that de participants with PFPS have a high hip adduction and in 5 of them high hip internal rotation, during the performance of functional activities. Likewise, positive results were found in all studies who evaluate the effectiveness of a hip program. CONCLUSIONS: Women with PFPS have kinematics alteration during sports movements or running. There are not enough studies to determine if men have the same alterations. In addition, improvements in symptoms and health status were found in participants with PFPS after a hip strength program. However, improvements don't appear in biomechanical alterations during dynamic activities.

[gl] INTRODUCIÓN: As alteracións a nivel das estructuras de estabilización da patela, foron consideradas como o principal factor desencadenante do PFPS, pero actualmente, a literatura recolle que un descentraxe da patela no plano frontal, pode estar causado pola mala mecánica da cadeira durante a realización de actividades funcionais ou xestos deportivos. OBXECTIVO: coñecer se as alteración funcionais da cadeira poden repercutir negativamente no síndrome femoropatelar. Así mesmo, determinar se un programa de fisioterapia de recuperación ou normalización da forza muscular da cadeira pode beneficiar a este síndrome. MATERIAL E MÉTODO: a busca de información realizouse nas bases de datos de ciencias da saúde PubMed, PEDro, Scopus, CINHAL e Sportdiscuss, entre os meses de febreiro e abril de 2016. A calidade metodolóxica dos estudos incluidos foi medida coa escala PEDro e o grado de evidencia coa escala OCEMB (Center of Evidence-Based Medicine, Oxfor) RESULTADOS: 11 artigos cumpliron os criterios de inclusión. Encontruse en 6 artigos un aumento da aducción de cadeira e en 5 deles un aumento da rotación interna durante a realización de actividades funcionais nos participantes con PFPS. Así mesmo, encontraronse resultados positivos en todo os estudos que valoraron a eficacia dun programa de fortalecemento da cadeira. CONCLUSIÓNS: : As mulleres con PFPS presentaron alteracións biomecánicas durante a realización de xestos deportivos ou carreira, mentres que non existen suficientes estudos para determinar se os homes teñen as mismas alteracións. Ademáis tras un programa de forza de cadeira, encontráronse melloras na sintomatoloxía e no estado de saúde dos participantes con PFPS, sin embargo non aparece melloría nas alteracións biomecánicas durante a realización de actividades dinámicas.
