Abstract
The aetiology of recurrent patellofemoral instability (PFI) is multifactorial. These factors include both demographic and anatomic risk factors. Demographic risk factors for recurrent instability include young age, female sex, family history and most importantly, a history of previous ipsilateral or contralateral patellar dislocations. Anatomic factors include generalized ligamentous laxity, neuromuscular imbalance, coronal or axial malalignment, trochlear dysplasia, patella alta and an elevated tibial tuberosity to trochlea groove (TT-TG) distance. Understanding and recognizing these different risk factors for each individual patient who presents with recurrent PFI is fundamental to achieving good outcomes when treating this often-complex patient group.
The main focus of this review is to explore the clinical assessment, radiological investigations and different surgical treatment options available for patients who present with recurrent PFI.
期刊介绍：
Orthopaedics and Trauma presents a unique collection of International review articles summarizing the current state of knowledge and research in orthopaedics. Each issue focuses on a specific topic, discussed in depth in a mini-symposium; other articles cover the areas of basic science, medicine, children/adults, trauma, imaging and historical review. There is also an annotation, self-assessment questions and a second opinion section. In this way the entire postgraduate syllabus will be covered in a 4-year cycle.
