This study will compare anatomic Medial Patellofemoral Reconstruction from Hamstring graft with non anatomic reconstruction according to Campbell. The purpose of this study is to evaluate which type of treatment recurrent patella dislocation provides to better clinical, radiological and laboratory outcomes.
Recurrent patella dislocation require surgery treatment. It provides to less cartilage degeneration and slow down knee osteoarthritis. Medial retinacular complex is injured in first time patella dislocation and its reconstruction is necessary. In literature there can be found many surgical reconstruction technics: anatomical or non anatomical (functional). But there is lack of evidence which technic provides to better outcomes - reduce the possibility to patella dislocation and progression of osteoarthritis in patellofemoral joint. Nowadays the choice of performed surgery depends on surgeons personal assessment.

| Imaging modality X-ray | Patellofemoral Joints Biomechanics improvement measured by patella tilt | 1 year |
| Imaging modality X-ray | Patellofemoral Joints Biomechanics improvement measured by Q angle | 2 years |
| Imaging modality CT | Patellofemoral Joints Biomechanics improvement measured by Insall-Salvati ratio. The Insall-Salvati ratio or index is the ratio of the patella tendon length to the length of the patella and is used to determine patellar height. he Insall-Salvati ratio was initially determined on a 30° flexed lateral knee x-ray and was later applied to sagittal MRI. Distance lines are used to calculate Insall-Salvati ratio: A: patellar tendon length (TL): length of the posterior surface of the tendon from the lower pole of the patella to its insertion on the tibia B: patellar length (PL): greatest pole-to-pole length Insall-Salvati ratio = A/B (or TL/PL). patella baja: <0.8 normal: 0.8-1.2 patella alta: >1.2 | 2 years |
