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.

RECRUITINGImaging modality X-ray
Patellofemoral Joints Biomechanics improvement measured by patella tilt
Time frame: 1 year
Imaging modality X-ray
Patellofemoral Joints Biomechanics improvement measured by Q angle
Time frame: 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

Knee Injury and Osteoarthritis Outcome Score
Knee Injury and Osteoarthritis Outcome Score; The score is a percentage score from 0 to 100, 0 representing extreme problems and 100 representing no problems.KOOS is intended to be used for knee injury that can result in post traumatic osteoarthritis (OA); KOOS has high test-retest reliability. In patients with knee injury, ICCs for the Pain subscale range from 0.85-0.93, the Symptoms subscale from 0.83-0.95, the ADL subscale from 0.75-0.91, the Sport/Rec subscale from 0.61-0.89 and the QOL subscale from 0.83-0.95. In patients with knee OA, ICCs for the Pain subscale range from 0.8-0.97, the Symptoms subscale from 0.74-0.94, the ADL subscale from 0.84-0.94, the Sport/Rec subscale from 0.65-0.92 and the QOL subscale from 0.6-0.91 (4).

Pain Visual Analog Scale
The pain VAS is a unidimensional measure of pain intensity. The most simple VAS is a straight horizontal line of fixed length, usually 100 mm. The ends are defined as the extreme limits of the parameter to be measured (symptom, pain, health)\[8\] orientated from the left (worst) to the right (best).
