Patellofemoral instability is characterized by pain during normal daily activities and frequent dislocation events. In the reported case, an adolescent girl, aged 15 years, affected by left patellofemoral instability, underwent surgery with a double technique comprising tibial tubercle distalization and medial patellofemoral ligament reconstruction. In case of patella alta associated with patellofemoral instability, surgical treatment should focus on medial patellofemoral ligament repair and on recurrent instability prevention.

Background: Tibiofemoral rotation is an emerging parameter, especially in assessing patellofemoral instability. However, reference values in the literature are inconsistent regarding the used imaging modality and do not consider the effect of knee flexion during image acquisition.
Purpose: To analyze the differences in tibiofemoral rotation measurements between computed tomography (CT) and magnetic resonance imaging (MRI).

Background: Patellofemoral pain (PFP) is a common musculoskeletal disorder resulting in anterior knee pain. Physiotherapy is the current standard treatment, while surgical intervention (tibial tubercle transfer [TTT]) is reserved for chronic cases when nonoperative treatment has failed. TTT can result in clinically meaningful improvement in patients with patellofemoral maltracking without instability.

Background: Trochleoplasty is a surgical consideration for the treatment of high-grade trochlear dysplasia. The safety profile of this procedure remains particularly unclear in the skeletally immature population where concerns exist regarding physeal arrest and the development of premature patellofemoral arthritis. The purpose of this study was to systematically review the literature to evaluate trochleoplasty use, outcomes and complications observed among pediatric patients.

Background: Considerable variability exists in the described clinical and radiographic indications for use, surgical techniques, postoperative management, and risk profile after trochleoplasty for the management of patellofemoral instability (PFI). In areas of clinical uncertainty, a cohesive summary of expert opinion and identification of areas of variation in current practice can be useful in guiding current practice and future research efforts.
Purpose: To assess the current indications for use, surgical techniques, postoperative rehabilitation practices, and observed complication profile for trochleoplasty in the management of PFI among surgeons who perform this procedure.
Purpose: To translate and adapt the Norwich Patellar Instability (NPI) score into Norwegian, and second, to examine the psychometric properties of the Norwegian version (NPI-No).
Methods: NPI was translated according to international guidelines. A cohort of 107 patients surgically treated for recurrent patellofemoral instability completed NPI-No, related questionnaires and functional tests prior to and six months post-surgery.
