Acute quadriceps tendon ruptures disrupt the continuity of the extensor mechanism and must be treated surgically. Tendon reattachment with suture anchors has recently been shown to be biomechanically superior to reattachment through transosseous tunnels. In this context, arthroscopy is an interesting alternative. It can limit postoperative wound healing and infectious complications, while ensuring functional outcomes that are equivalent to standard techniques. The goal of this technical note is to describe an original, reproducible method for arthroscopic reattachment of the quadriceps tendon with suture anchors. Four patients were operated using this technique in a pilot study. No wound healing, infectious complications or re-tears were observed. At 6 months' postoperative, the mean subjective IKDC score was 85.8/100.
> Les dystrophies musculaires avec déficit en collagènes VI constituent des affections rares avec une présentation clinique très variable, couvrant un large spectre intermédiaire allant des formes congénitales, de type Ullrich, aux formes tardives de type Bethlem. Elles sont dues à des mutations des gènes COL6A1, COL6A2 ou COL6A3. Elles ont en commun de se traduire par un déficit moteur et des rétractions progressifs. L'atteinte respiratoire participe à la gravité de l'affection pour certains patients. Elle est due au déficit du diaphragme et des muscles intercostaux, à la rétraction de la cage thoracique, et à la scoliose. Une atteinte parenchymateuse pulmonaire liée à la fragilité de la matrice extracellulaire favorisant la survenue de pneumothorax est suspectée. <
