Antecedentes: La reconstrucción del ligamento patelofemoral medial ( MPFL ) es un procedimiento de rutina para la inestabilidad patelar. La mayoría de las técnicas requieren la fijación de hardware o un procedimiento ósea en la rótula . Sin embargo , la mayoría de las complicaciones descritas en la literatura se puede atribuir a la fijación de la rótula . La ” técnica quad superficial” utiliza el deslizamiento superficial del tendón del cuádriceps como el material de injerto , que proporciona una mejor coincidencia anatómica a la LFRM nativa .
Hipótesis: La técnica quad superficial proporciona una fijación anatómica rotuliano sin un procedimiento óseo y sin complicaciones rotulianas .
Diseño del estudio: Las series de casos ; Grado de comprobación , 4 .
Métodos : El estudio incluyó a 32 pacientes ( 10 varones , 22 mujeres , edad media , 25 años ) que se sometieron a la reconstrucción MPFL utilizando la técnica quad superficial y que fueron seguidos durante una media de 38 meses . Evaluación objetiva se realizó para marcar un Kujala se obtuvieron antes de la operación y en el momento del seguimiento final .
Resultados : No se evidenciaron complicaciones rotulianas , incluyendo una nueva luxación , en el presente estudio . La puntuación media de Kujala mejoró a 91,25 (rango, 73-100 ) de una puntuación preoperatoria de 49,31 (rango, 23-62 ) .
Conclusión : Los resultados son comparables con los de otros estudios en la literatura que utiliza injertos de tendón de la corva , pero sin complicaciones rotulianas asociados . La técnica quad superficial utiliza material de injerto que presenta una mejor coincidencia anatómica a la MPFL nativo. Se proporciona una fijación anatómica rotuliano sin un procedimiento ósea.


Background: Medial patellofemoral ligament (MPFL) reconstruction is a routine procedure for patellar instability. The majority of the techniques require hardware fixation or a bony procedure at the patella. However, most of the complications described in the literature can be attributed to patellar fixation. The “superficial quad technique” uses the superficial slip of the quadriceps tendon as the graft material, which provides a better anatomic match to the native MPFL.
Hypothesis: The superficial quad technique provides anatomic patellar fixation without a bony procedure and without patellar complications.
Study Design: Case series; Level of evidence, 4.
Methods: The study included 32 patients (10 male, 22 female; mean age, 25 years) who underwent MPFL reconstruction using the superficial quad technique and who were followed for a mean duration of 38 months. Objective assessment was performed and Kujala scores were obtained preoperatively and at the time of final follow-up.
Results: There were no patellar complications, including redislocation, in the present study. The mean Kujala score improved to 91.25 (range, 73-100) from a preoperative score of 49.31 (range, 23-62).
Conclusion: The results were comparable with those of other studies in the literature that used hamstring grafts, but without associated patellar complications. The superficial quad technique uses graft material that is a better anatomic match to the native MPFL. It provides anatomic patellar fixation without a bony procedure.
