Popis: Recurrent patellar dislocation is defined as a dislocation occurring more than once. There is no consensus as to the choice of operative technique for recurrent dislocation in adolescents. Recently, great importance has been attributed to MPFL reconstruction. The aim of this study is to evaluate the value of MPFL reconstruction (group A) in adolescents by comparing MPFL reconstruction with combined soft tissue proximal and distal alignment (group B). MPFL reconstruction by means of Avikainen’s technique was performed on 32 knees. Another 33 knees were subject to the techniques combining retinacular plasty, vastus medialis advancement, and Roux-Goldthwait procedure. The results were assed clinically (Lyscholm scale and the Kujala Anterior Knee Pain Scale) and using X-rays (axial and lateral knee view). Isokinetic assessment of the quadriceps and hamstring was performed. No statistically significant differences between the two groups were observed regarding the Lyscholm and Kujala scales, the presence of redislocation (9.3 % for group A versus 12.1 % for group B), apprehension test, abnormal patellofemoral angle, abnormal Caton index (p > 0.05). A statistically significant difference between the groups was observed regarding the rate of pain complaints, the incidence of an abnormal congruence angle, patellar medialization and deficits in the peak torque of the hamstring between the two angular velocities (p
