Complications and Radiographic Outcomes of Tibial Tubercle Osteotomy at Minimum 5-Year Follow-up.

Background: Tibial tubercle osteotomy (TTO) is a commonly utilized surgery in the treatment of patellofemoral instability and chondrosis. A number of case series studies have reported on the mid- and long-term outcomes with varying complication rates.

Purpose: To report the incidence of major complications after TTO and the rate of progression of knee osteoarthritis at midterm follow-up.

Analyzing Alignment Error in Tibial Tuberosity-Trochlear Groove Distance in Clinical Scans Using 2D and 3D Methods.

Background: Tibial tuberosity-trochlear groove distance (TT-TG) is often used as a primary metric for surgical decision-making in the treatment of patellofemoral instability (PFI), particularly when considering tibial tubercle transfer. Although TT-TG has high interrater reliability, it is prone to measurement differences caused by the alignment of the patient's leg in a scanner gantry, potentially influencing surgical decision-making. Quantification of this error within the clinical literature remains limited.

A Cross-Sectional Analysis of Factors Promoting Intergenerational Resilience in Adolescent Youth With Refugee Status.

Background: Adolescent youth occupy a critical and complex position in refugee families who resettle in a third country.

Objectives: We examined the potential impact of health- and family-related factors on the social and behavioral adjustment outcomes of refugee adolescent youth.

Methods: Situated within an explanatory sequential mixed methods study, we used unadjusted and adjusted multinomial logistic regression to identify trauma, health, and socioecological characteristics of war-affected families associated with social and behavioral adjustment in 72 Karen adolescent youth resettled in the United States.

Three-Dimensional Imaging of the Patellofemoral Joint Improves Understanding of Trochlear Anatomy and Pathology and Planning of Realignment.

Three-dimensional (3D) modeling using digital or printed models provides a unique perspective that caters to cognitive spatial ability in a way that can add to our understanding and mental representations of human anatomy. This is particularly useful in the setting of trochlear dysplasia, where the morphology of the groove can exhibit substantial variability and complexity. Using 3D reformatted images and models, a pragmatic understanding of how morphology influences patellofemoral pathology can be gleaned.

The Morphologic Patella Entry Point Into the Proximal Trochlea Is More Lateral in Recurrent Dislocators Than Controls as Measured by Entry Point-Trochlear Groove Angle.

Purpose: To create a metric for evaluating the degree of laterality of the patella's entry into the trochlea, the entry point-trochlear groove (EP-TG) angle, and to evaluate if this laterality is associated with recurrent patella instability.

Methods: The time frame of the study was January 2020 to February 2023. The inclusion criteria were patients treated by the senior author (J.
