Correction of a congenitally dislocated knee cap (femoropatellar dysplasia)

Causes
Congenitally insufficient formation of the knee cap or of the femoral condyle may lead to a change in the fit between the rear surface of the kneecap and the corresponding groove on the front of the thighbone.

Symptoms
Pain in the knee occurs primarily when bending over, sitting for a long time, or walking downstairs. In serious cases, the kneecap may slide out (patella luxation).

Possible therapies
Depending on the age of the patient and the seriousness of the misfit between the bones, minimally invasive surgery, lengthening of the tendon, or shifting of the point of attachment of the kneecap tendon to the head of the shinbone may be performed.

Dr Braune treats less serious cases arthroscopically, by splitting the outer attachment of the kneecap, a procedure known as arthroscopic lateral release.
