Clinical Trial Summary

Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon.The aim of the study is to assess the effectiveness of this surgical procedure in long follow-up. The outcomes will be evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton-Deschamps index, sulcus angle, congruence angle, and patellofemoral angle). This is a continuation of the research published in 2015 with longer follow-up at least 10 years. All available patients will be evaluated with the same protocol, using the same methods and devices. Functional outcome is planned to be measured with scales as above. In radiological assessment Merchant and lateral knee weight bearing view and additionally MRI will be performed. Isokinetic test will be performed in two speeds of 60 and 180 deg/s. Most of important isokinetic parameters such as peak torque, torque in 30 deg, time to peak torque, peak torque to body weight both for quadriceps and hamstrings will be measured and compared to those from former research. Dedicated statistical test will be used for both: analysis of present status and differences from former results.


Clinical Trial Description

Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL) becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of the study is to assess the effectiveness of this surgical procedure in long follow-up. The outcomes will be evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton-Deschamps index, sulcus angle, congruence angle, and patellofemoral angle). This is a continuation of the research published in 2015 with longer follow-up at least 10 years. All available patients will be evaluated with the same protocol, using the same methods and devices. Functional outcome is planned to be measured with scales as above. In radiological assessment Merchant and lateral knee weight bearing view and additionally MRI will be performed. Isokinetic test will be performed in two speeds of 60 and 180 deg/s.
