Sagot :
Microfracture is a minimally invasive procedure that effectively treats minor cartilage abnormalities in the near term. The ICRS-score is the most telling indicator of a decline in outcomes that begins 18 months following surgery. Young individuals with femoral condyle abnormalities had the highest prognostic odds.
How does microfracture work?
Because of their great efficacy, low cost, and short operating times when compared to other surgical methods, microfractures are frequently used as the first surgical option for the treatment of osteochondral lesions. Despite the patellofemoral compartment being the second most prevalent compartment for such lesions, the results of microfractures for retropatellar chondral abnormalities are mediocre when compared to other compartments of the knee. The patella's mobility, which is particularly noticeable when the patient's knee is extended, as is the situation in this kind of surgery, is one of the main causes of the inferiority.
Manual pressure has historically been used to overcome this hurdle, but this method is unreliable and prone to technical issues like skiving of the awl and restricted operating perspective, as well as consequences like fractures. This Technical Note describes a novel internal stabilization technique we call "house-on-stilts" that involves several Kirschner wire fixations into the patella and femur to immobilize the patella. This method supports both the debridement step before microfracturing without adding to operating costs or time.
