Study summary

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.

Read the detailed description

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.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Imaging modality X-ray

    Patellofemoral Joints Biomechanics improvement measured by patella tilt

    Time frame: 1 year

  2. Imaging modality X-ray

    Patellofemoral Joints Biomechanics improvement measured by Q angle

    Time frame: 2 years

  3. 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

    Time frame: 2 years

  4. Imaging modality CT

    Patellofemoral Joints Biomechanics improvement measured by TT-TG (line between tibial tuberosity and trochlear groove)

    Time frame: 2 years
