Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
