Comparison of Two Graft Choices in Mediale Patellofemoral Ligament Reconstruction (MPFL)

Aarhus University Hospital

Status: Active, not recruiting

Conditions: Patellar Dislocation

Treatments: Procedure: Quadriceps graft

Study type: Interventional

Funder types: Other

Identifiers

NCT05706363

Danish EC: 1-10-72-75-17

Details and patient eligibility

About

The purpose of this study is to elucidate surgical techniques for reconstructing MPFL in the treatment of chronic patella instability. The two techniques are conventional technique with the gracillis and screw fixation in the femur which is compared with new technique where the QT tendons and anchor fixation in the femur are used.

It would be investigated which technique provides the best stability with the least postoperative pain from the reconstruction and the lowest frequency of patellar reluxation.

Enrollment: 90 estimated patients

Sex: All

Ages: 15 to 40 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients between 15 and 40 years of age with chronic tendency to lateral patellar dislocation (defined as 2 or more verified dislocation cases)

Exclusion criteria

• Patients with known rheumatoid arthritis.
• Patients with arthroscopically detected osteoarthritis (grade 3 cartilage lesion)
• Inability to follow a normal rehabilitation regime.
• Previous ligament surgery in injured knees.
