简要总结
The purpose of this project is to investigate the treatment outcome after MPFL reconstruction in children as a treatment for chronic patellar instability, where the superficial part of the quadriceps tendon is fixed to the femur with anchors.
The outcome will be compared with a healthy cohort matched on age and gender.
详细描述
Lateral patella dislocation (PL) is defined as a total dislocation of the patella out of the trochlea.
In chronic patella instability, where the patella has been repeatedly dislocated, the treatment is most often surgical. The main ligamentous structure that stabilizes the patella against lateralization is the medial patello-femoral ligament (MPFL). The MPFL is a centimeter-thin ligamentous structure that runs from the upper medial patellar border to the medial femoral epicondyle. This ligament is torn in more than 90% of cases of PL and healing of the ligament is often insufficient, especially if there are predisposing factors in the knee joint such as dysplasia of the patello-femoral joint, high standing patella (patella alta) and hypermobility.
MPFL reconstruction (MPFL-r) can be performed with many different surgical techniques, but the basic principle is to use autologous tendon tissue to create a new MPFL by anchoring the new tendon tissue to the medial patellar border and the medial femoral epicondyle, while ensuring isometry of the reconstruction.
A number of different methods have been described for anchoring the new MPFL to the patella and femoral condyle.
The most commonly used type of graft for MPFL-r is the gracilis tendon, which is fixed with screws in the femur bone preceded by drilling a channel in the femoral condyle.
