Comparing two surgical methods for recurrent patellar dislocation
Medial Patellofemoral Ligament (MPFL) Reconstruction With or Without Tibial Tubercle Transfer for Recurrent Patellar Instability
This study is testing whether a knee surgery that includes moving a bone piece works better than one that doesn’t for people who keep having their kneecap dislocate.

What this trial studies
This study compares the clinical outcomes of Medial PatelloFemoral Ligament (MPFL) reconstruction with and without tibial tubercle transfer in patients suffering from recurrent patellar dislocation. A total of 70 patients were randomly assigned to one of the two surgical approaches, and their knee function was evaluated preoperatively and at 2 years post-surgery using established scoring scales. Follow-up assessments included CT imaging and monitoring for redislocation or episodes of instability. The goal is to determine which surgical method provides better stability and function for patients.
Who should consider this trial
Good fit: Ideal candidates for this study are patients with recurrent patellar dislocation or instability and a TT-TG value of 20 mm or greater.
Not a fit: Patients with bilateral patellar dislocation, previous surgeries on the affected leg, or severe trochlear dysplasia may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical techniques for treating recurrent patellar dislocation, enhancing patient outcomes.
How similar studies have performed: Previous studies have explored MPFL reconstruction techniques, but the specific comparison of MPFL reconstruction with and without tibial tubercle transfer is relatively novel.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * recurrent patellar dislocation or instability,patients with TT-TG value equal to or greater than 20 mm,patients with closed epiphyseal plate TT-TG：Two lines drawn perpendicular to posterior bicondylar line, one line through middle of the trochlear groove(TG) and the second through tibial tuberosity (TT). Distance between the lines is measured. Exclusion Criteria: * bilateral patellar dislocation, a previous surgery in the involved leg,patients with open epiphyseal plate,patients with severe trochlear dysplasia
