Outcomes

Primary Outcomes

Pain measurement by numeric rating score

The primary outcome of this study is pain measured with the numeric rating score (NRS): 11-point NRS ranging from 0 (no pain at all) to 10 (the worst imaginable pain). A score of zero (0) will indicate that the patient is pain free, while a score of ten (10) will indicate that they are experiencing the worst pain imaginable.

Time frame: 2 months after injection in comparison to baseline

Secondary Outcomes

Patient Global Impression of Change (PGIC)

The PGIC rating is increasingly being used for determining clinically important change in measures such as ratings of pain. This scale is designed to quantify patient's improvement or deterioration over time, usually either to determine the effect of an intervention or to chart the clinical course of a condition. The scales ask that a person assess his or her current pain, recall that status at a previous time-point, and then calculate the difference between the two. * very much improved * much improved * minimally improved * no change * minimally worse * much worse * very much worse

Time frame: 2 months after injection

Use of analgesics

The quantity of analgesics that the patient assumes for the pain: * All stopped * Decreased * Equal * Increased

Time frame: 2 months after injection

Sleep

Question: 'your sleep quality is: * Improved * Equal * Worsened'

Time frame: 2 months after injection

Walking ability

Question: 'after the treatment, you can walk: * More than before * Same as before * Less than before'

Time frame: 2 months after injection

Patient satisfaction

Question: are you satisfied with the result: YES/NO
