Recovery of Lower Extremity Function in the Initial Year Following Periacetabular Osteotomy: A Single Subject Analysis.

Background: Little is known regarding how lower extremity joint function recovers in the 6 months following periacetabular osteotomy (PAO) for activities other than walking.

Purpose: Assess patient-reported outcomes, hip strength, lower extremity joint moments, and moment distributions during sit-to-stand in a female athlete during the one-year period following PAO.

Methods: Patient-reported outcomes (i.

Patellofemoral joint kinetics in females when using different depths and loads during the barbell back squat.

Back squats are a common strengthening exercise for knee and hip musculature. However, repetitive loaded movements like backs squats result in high patellofemoral joint loading and therefore may contribute to the development of common overuse injuries. Thus, it is important to understand how changing parameters such as squat depth or load influences patellofemoral loading.
