MPFL vs Campbell in Recurrent Patella Dislocation
- Conditions
- Recurrent Patella Dislocation
- Interventions
- Procedure: Surgery
- Registration Number
- NCT05488275
- Lead Sponsor
- Centre of Postgraduate Medical Education
- Brief 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.
- 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.

Group Intervention Description MPFL static Surgery Medial Patellofemoral Ligament reconstruction with hamstring graft - static procedure Campbell Surgery Medial Patellofemoral Ligament reconstruction using non-anatomic reconstruction (quadriceps femoris plasty - Campbell method) MPFL dynamic Surgery Medial Patellofemoral Ligament reconstruction with hamstring graft - dynamic procedure
- Primary Outcome Measures
Name Time Method Imaging modality X-ray 2 years Patellofemoral Joints Biomechanics improvement measured by Q angle
Imaging modality CT 2 years Patellofemoral Joints Biomechanics improvement measured by TT-TG (line between tibial tuberosity and trochlear groove)
- Secondary Outcome Measures
Name Time Method Knee Injury and Osteoarthritis Outcome Score 24 months 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).
Functional tests 24 months hop-for-distance
Pain Visual Analog Scale 24 months 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).
Knee Injury and Osteoarthritis Outcome Score Patellofemoral 24 months the 'Knee Injury and Osteoarthritis Outcome Score Patellofemoral' questionnaire (KOOS-PF) is frequently used to measure symptoms and function among the people with PFJ-OA. This scale is scored from 0 to 100, with 100 representing no disability and 0 representing maximum disability
The Victorian Institute of Sport Assessment 24 months The Victorian Institute of Sport Assessment-Patella (VISA-P) is a questionnaire to assess the severity of patellar tendinopathies. minimum 0, maximum 100 for asymptomatic
International Knee Documentation Committee 24 months IKDC is subjective scale that provides patients with an overall function score. Total to a scaled number ranges from 0 to 100. higher number representing higher levels of function.
Tegner Lysholm Knee Scoring Scale 12 months The Lysholm Knee Scoring Scale is a patient-reported instrument that consists of subscales for pain, instability, locking, swelling, limp, stair climbing, squatting, and the need for support. Scores range from 0 (worse disability) to 100 (less disability).
Pain Visual Analog Scale. 12 months, 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).
