NCT06265675
Lead Sponsor
Gaziler Physical Medicine and Rehabilitation Education and Research Hospital
Brief Summary

There are different neurolysis methods. Aim of this study is to compare two different methods, phenol block and corticosteroid local anesthetic block.

Detailed Description

Knee osteoarthritis is one of most frequent reason of knee pain. There are different treatment methods such as analgesic drug treatment, physical therapy techniques, intraarticular injections and neurolysis techniques. In this study, we will compare neurolysis techniques these are phenol block and corticosteroid local anesthetic block.

Primary Outcome Measures
NameTimeMethod
Numeric Rating Scale (NRS)Before the intervention, 4 weeks after the intervention and 3 months later

Average knee pain is assessed using an 11-point NRS with terminal descriptors of no pain (score 0) and extreme pain (score 10).

Secondary Outcome Measures
NameTimeMethod
Frequency of analgesic usageBefore the intervention, 4 weeks after the intervention and 3 months later

Assessment of analgesic number that used by patient with knee osteoarthritis

Sixt Minute Walk Test (6MWT)Before the intervention, 4 weeks after the intervention and 3 months later

A 6 minute walk test is a submaximal exercise test that measures the distance walked over the span of 6 minutes.

Western Ontario and McMaster Universities Arthritis Index (WOMAC)Before the intervention, 4 weeks after the intervention and 3 months later

We will use the WOMAC in the Likert version where question are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. So the sum of the scores ranges from 0 (the best) to 96 (the worse).

Patient Global Impression of Change (PGIC)4 weeks after the intervention and 3 months later

The PGIC in pain and function will be measured with a 5-point Likert scale (1-5) on the applicable follow up visits. The patients will be asked to rate the following statements:

Please imagine how you would have described your pain intensity before the procedure. How do you feel today as compared to baseline (Start of the study) as far as your knee pain caused by OA is concerned? Please imagine how you would have described the functionality of your knee before the procedure. How do you feel today as compared to baseline (start of the study) as far as your knee functionality caused by OA is concerned?

The options on the Likert scale are:

much better slightly better no change slightly worse much worse

The Timed-Up and Go testBefore the intervention, 4 weeks after the intervention and 3 months later

This test measures the dynamic balance and functional mobility in older adults.A patient getting up from a chair from the sitting to the bipedal position, walking three meters, turning, returning, and sitting on the chair again.
