    Area of Science:

    • Orthopedic Surgery
    • Biomechanical Engineering

    Background:

    • Recurrent patellar dislocations and subluxations significantly impact knee function and quality of life.
    • Associated factors like high "Q" angle or patellar abnormalities may influence surgical decisions.

    Purpose of the Study:

    • To evaluate the efficacy of tibial tubercle transfer in managing patellar instability.
    • To determine optimal surgical techniques and outcomes for tibial tubercle transfer.

    Main Methods:

    • Retrospective analysis of 377 tibial tubercle transfer operations.
    • Surgical technique involved medial and distal advancement of the tibial tubercle.
    • Fixation methods varied, with a single screw proving sufficient in many cases.

    Main Results:

    Related Experiment Videos

    • Tibial tubercle transfer was generally satisfactory in 377 operations with an average follow-up of 3.5 years.
    • Medial and distal transplantation of the tubercle compensated for patella alta and aligned with the femoral shaft.
    • Arthrotomy was not always necessary, and specific considerations were made for open proximal tibial epiphysis.

    Conclusions:

    • Tibial tubercle transfer is an effective surgical option for patients with recurrent patellar dislocations or subluxations.
    • Careful consideration of tubercle advancement and alignment is crucial for successful outcomes.
    • The procedure offers a reliable solution for improving knee stability and function.
