Die Trochleaplastik bei Trochleadysplasie zur Therapie der rezidivierenden Patellaluxation

Current concepts on trochleoplasty procedures for the surgical treatment of trochlear dysplasia

“…In 1994, Bereiter presented another type of trochleoplasty known as the 'Bereiter' or 'thin-flap' technique (Fig. 5) [7]. In this procedure, a 3-5 mm osteochondral flap is first elevated from the whole of the trochlea.…”

Arthroscopic Deepening Trochleoplasty: The Technique

“…This article reviews the most common of these techniques currently in use. [1][2][3] In general, all of these deepening trochleoplasty techniques unload the compressive forces in the PF joint and both the Dejour and Bereiter technique reestablish osseous stability to the patella. Trochlear dysplasia is characterized by a shallow or domeshaped trochlea based on too much bone in the proximal and central part of the knee.…”

Recurrent dislocation of the patella accompanying hypotrochlea of the femur and malalignment of the patella

“…The treatment of trochlear dysplasia with malalignment of the patella needs to achieve realignment of the patella, such as transfer of the tibial tuberosity in patients with open epiphysis, which might lead to remodeling of the trochlear groove ( 6 ). Conversely, trochleoplasty should be considered carefully in cases with closed epiphysis in which remodeling following the realignment procedure may not be expected ( 7–10 ). Regarding these procedures, Kobayashi and Ou indicated trochleoplasty for cases with sulcus angle >150° with closed epiphysis and patella dislocation or subluxation in the early flexion phase ( 5 ).…”
