Quantitative assessment of patellofemoral osteoarthritis via the pressure band test: an innovative and objective test.

ABSTRACT:

Background

Patellofemoral osteoarthritis (PFOA) is a prevalent subtype of knee osteoarthritis (OA), but due to its nonspecific symptoms and costliness in imaging, it is difficult to diagnose accurately, with the currently available methods lacking sensitivity and accessibility. This study aimed to develop and validate a novel, noninvasive, and cost-effective pressure band test (PBT) for the quantitative assessment of PFOA severity.

Methods

This prospective cross-sectional study consecutively enrolled 1,059 participants between September 2022 and March 2024. Pain thresholds, defined as the lowest pressures needed to induce pain, were measured via a standardized PBT and validated against magnetic resonance imaging (MRI)-based Outerbridge scores, Kellgren and Lawrence (K&L) gra
