The Predictive Value of Ultrasonographic Quadriceps Muscle Parameters for Genicular Nerve Block Outcomes in Knee Osteoarthritis
The Role of Quadriceps Muscle Architecture Parameters in Predicting the Success of Genicular Nerve Block in Patients With Chronic Knee Osteoarthritis Pain
The goal of this observational study is to learn whether thigh muscle structure can help predict pain relief after a genicular nerve block in people with knee osteoarthritis. A genicular nerve block is an injection used to reduce pain signals from the knee.
The main questions are:
- Are muscle thickness, fiber length, and fiber angle linked to pain relief after the procedure?
- Are these muscle measurements linked to changes in physical function and quality of life?
Participants are adults aged 50 to 80 with long-term pain from osteoarthritis in one knee. They are already scheduled to receive a genicular nerve block as part of their regular medical care. The study does not assign participants to receive this procedure.
Before the procedure, researchers will use ultrasound to measure the vastus lateralis muscle in the thigh. Participants will also answer questions about pain, daily function, and quality of life. Researchers will repeat these assessments after 1 hour, 3 weeks, and 3 months. Pain relief will be considered successful when pain is at least half as severe as it was before the procedure.

Medidas de resultados primários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Change in Pain Intensity Assessed by the Numeric Rating Scale (NRS)
Prazo: Baseline , 3 weeks, and 3 months
|
Pain intensity will be assessed using an 11-point Numeric Rating Scale ranging from 0 (no pain) to 10 (worst imaginable pain).
Changes from baseline will be evaluated following ultrasound-guided genicular nerve block.
Lower scores indicate lower pain intensity.

Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Score
Prazo: Baseline, 3 weeks, and 3 months after the procedure
|
Description: Pain, stiffness, and physical function related to knee osteoarthritis will be assessed using the 24-item WOMAC questionnaire.
The total score ranges from 0 to 96, with higher scores indicating greater pain, stiffness, and functional impairment.
Changes from baseline will be evaluated following ultrasound-guided genicular nerve block.
|
Baseline, 3 weeks, and 3 months after the procedure

|
Change in Health-Related Quality of Life Assessed by the EQ-5D
Prazo: Baseline, 3 weeks, and 3 months after the procedure
|
Description: Health-related quality of life will be assessed using the EQ-5D questionnaire.
Responses will be converted into an EQ-5D index score, where higher scores indicate better health status.
A score of 1 represents full health, 0 represents a health state equivalent to death, and negative scores represent health states considered worse than death.
Changes from baseline will be evaluated following ultrasound-guided genicular nerve block.
