The management of patellofemoral instability is based on a thorough evaluation of predisposing anatomical factors. Patella alta is one of the utmost causes of objective instability. The resulting biomechanical changes can lead to recurrent patellar instability, pain, and focal degenerative alterations. Physical examination is paramount in the decision-making process. Imaging evaluation has evolved from X-ray-based methods to magnetic resonance imaging measurements, which enable a more accurate assessment of the patellotrochlear relationship. Treatment is based on selective correction of the risk factors, while tibial tubercle distalization osteotomy as well as medial patellofemoral ligament reconstruction are tools that must be rationally considered. The present article reviews the surgical rationale for the treatment of patella alta in patellofemoral instability.
