Recurrent patellar dislocation occurs when the kneecap (patella) displaces from its normal position in the femoral trochlea, and this recurs repeatedly. It is a condition that can cause pain, knee instability, functional limitation, and reduced knee motion.
We use modern and excellent surgical techniques to intervene on the pathology “Recurrent patellar dislocation“
Recurrent patellar dislocation occurs when the kneecap (patella) displaces from its normal position in the femoral trochlea, and this recurs repeatedly . It is a condition that can cause pain, knee instability, and functional limitation and reduced knee motion.
Recurrent patellar dislocation : causes
Among the causes of recurrent patellar dislocation, we can find:
Anatomical factors : abnormalities in the shape of the patella, the femoral trochlea, or in the alignment of the lower limb (e.g., femoral anteversion, genu valgum, patella alta)
Ligamentous factors : laxity of the ligaments that stabilize the patella, particularly the medial patellofemoral ligament (MPFL).
Muscle factors : Imbalance or weakness of the quadriceps muscles, particularly the vastus medialis oblique (VMO).
Trauma : Direct trauma or sudden movements of the knee can cause the initial dislocation and, if not treated properly, lead to recurrence.
Recurrent patellar dislocation: treatment
Treatment of recurrent patellar dislocation is initially conservative, primarily with physiotherapy, to strengthen and rebalance the muscles.
If conservative treatment fails, surgical treatment may include:
reconstruction of the MPFL
transpositions of the tibial tuberosity
trochleoplasty
It should be noted that some of these procedures cannot be performed on patients who are still growing.
