About

The purpose of the study is:

1. to analyze the success of operative stabilization of the patellar joint with the reconstruction of the medial patellofemoral ligament (MPFL) in terms of the subjective status of the knee, the general quality of life, and physical activity
2. to study the influence of specific preoperative (demographic and anamnestic data of the patient, radiological parameters of the knee joint) and intra-operative factors (place of femoral insertion of MPFL graft, patella height, degree of damage to the cartilaginous surfaces of the knee joint) on the subjective outcome of surgical treatment.
