Measurement Requirements

This trial is evaluating whether Embozene Microspheres will improve 1 primary outcome and 5 secondary outcomes in patients with Knee Pain Chronic. Measurement will happen over the course of 6 months.

Assess for associations between mental health and post TKA pain as assessed by the MHI-5 by comparing scores at 1 week, 1, 3, and 6 months to the pre-procedure score.
KOOS - Pain subscale KOOS Scale - Pain
Estimate the effect of genicular artery embolization on the change in knee pain, as assessed by the KOOS, at 6 months post vs. pre-intervention, in patients with chronic knee pain following TKA
VAS Scale
Estimate the effect of genicular artery embolization on the change in knee pain, as assessed by the VAS scale, at 1 week, 1, 3, and 6 months, in patients in patients with chronic knee pain following TKA.
CRP & IL-6
Estimate the effect of genicular artery embolization on CRP and IL-6, by comparing baseline laboratory values to 6-month post procedure values.
Analgesic Utilization
Estimate the effect of genicular artery embolization on analgesic utilization as measured by morphine equivalents and non-steroidal anti-inflammatories utilization
KOOS - Non-Pain Components
Estimate effect in non-pain components of the KOOS score (KOOS Symptoms, KOOS ADL, KOOS Sport ADL, and KOOS QOL) by comparing these scores at 1 week, 1,3, and 6 months to the pre-procedure score.

Approximately 19.9 million U.S. adults report having knee pain for at least two months in a given year. It is important to understand the impact of knee pain on individuals' daily lives and what treatment may be most appropriate.

Anonymous Patient Answer

How serious can knee pain chronic be?

Recent findings of studies on the diagnosis and treatment of [knee pain]( provide a basis for considering knee pain chronic as being of low or moderate severity. In the past, however, there has been emphasis on the use of radiographic techniques of assessing and diagnosing patellofemoral pain and its sequelae as potentially disabling and disabling. However, the results of recent studies have suggested that patellofemoral pain, while not necessarily a debilitating condition, does have significant negative impacts of daily living and is highly likely to increase the risk of future joint pain and other health problems. The implication is that knee pain chronic is a serious disabling condition that significantly impacts quality of life and is likely to have substantial negative impacts on the individual.
