Assessing the Association Between WBCT PFJ Morphological Metrics and Knee Symptoms

Patellofemoral joint (PFJ) pain is a common, often chronic, aching pain behind or around the kneecap, frequently called "runner's knee". It occurs when the kneecap does not glide smoothly over the thigh bone, often due to muscle weakness or overuse. It makes sitting for long periods, climbing stairs, or kneeling painful. Symptomatic knee osteoarthritis (OA) is a common, long-term condition where the protective cartilage in the knee joint wears away, causing the bones to rub together, leading to daily pain and stiffness. In simple terms, it is a "wear-and-tear" disease of the entire joint that makes walking, climbing stairs, or bending the knee difficult. The PFJ is where the patella (kneecap) meets the femoral trochlea (front part of the lower thigh bone) at the front of the knee. Patellar tracking refers to the movement of the patella that begins to engage in the distal femoral trochlear groove (smooth, U-shaped groove at the bottom of the thigh bone). By doing this study, we hope to advance clinical knowledge of the PTJ features in a more natural position by using weight-bearing computed tomography (WBCT) images while the leg is straight and slightly bent. Determining links between specific knee symptoms and the PTJ structure on WBCT images could enable providers to effectively target the underlying causes and to develop targeted treatments.

Mindful Miles Pilot Feasibility Study

The goal of this single-arm pilot study is to examine the feasibility, acceptability, and preliminary efficacy of a progressive outdoor mindful physical activity intervention delivered via the Headspace mobile application for individuals with patellofemoral pain. AIM 1: Determine the feasibility and acceptability of the mindful activity intervention. AIM 2: Determine the preliminary efficacy of the mindful running intervention to improve the primary outcome of (2a) anterior knee pain, and secondary outcomes of (2b) kinesiophobia and (2c) running cadence and vertical forces (gait kinematics) in individuals with PFP. Our central hypothesis is that the intervention will be feasible and acceptable and will improve pain, kinesiophobia (injury-related fear), and running cadence (steps per minute) in individuals with patellofemoral pain. Participants will complete a three-phase progressive mindful physical activity intervention that involves: Phase 1: Introduction to mindfulness Phase 2: Guided mindful running Phase 3: Mindful running.

INFLUENCE OF SELECTED POSITIONS ON HIP ABDUCTORS STRENGTH AND ACTIVATION IN PATELLOFEMORAL PAIN SYNDROME IN MALES

The study aims to explore the effect of body position (side-lying versus standing) on hip abductors muscle strength and activation in individuals with and without PFPS and then to compare these measures between the two groups in each position

Effect of Specific Versus General Hamstring Stretch on Clinical Outcomes in Patellofemoral Pain Syndrome (PFPS)

This randomized, Single-blind, parallel-group trial will compare the effects of three hamstring stretching interventions-general hamstring Muscle Energy Technique (MET), medial hamstring MET, and lateral hamstring MET-each combined with standardized TENS and progressive hip/knee strengthening, on hamstring flexibility (knee-extension ROM), anterior knee pain (Arabic Kujala score), pain intensity visual analogue scale (VAS), and lower-limb strength (hand-held dynamometer) in adults with patellofemoral pain syndrome (PFPS).
