patellofemoral instability or recurrent patellar dislocation in children operated with the
proximal realignment technique. Materials and methods: It is a series of 10 knees in
7 children, with proximal patela realignment patela using the Insall technique. The most
important role of the patela is to increase the quadriceps efficiency. The patelo -femoral
instability is defined as a condition in which there is insufficient coupling of the patela
with the femoral trochlea during the knee range of motion. In children this instability
may be due to various anatomical factors leading to recurrent dislocation of the patela.
There are surgeries proximal o distal to the patela level. Results: Good results were
obtained on 8 knees, without pain, neither dislocation nor residual instability and having
good stability and safety during the gait. One patient showed redislocation and another
patient with Down syndrome had a subluxation. Conclusions: proximal realignment in
this series shows good results in patients who had little trochlear dysplasia with mild
alteration of the Q angle. It is a technique not widely used but has indicated in selected
cases. Today, the patelo - femoral medial ligament reconstruction, can be used in
combination with proximal realignment techniques. Patients with collagen problems
like Marfan and Down syndrome usually have redislocation and require some other
procedures for patelar stabilization.
