Conditions

Joint pain : lower leg [fibula, tibia, knee joint]. M17.9

Interventions

Group 1: Patients who achieved a reduction in pain intensity of> / = 3VAS points through the test infiltration are treated with the cooled RFTA probe. VAS scores are obtained before test infiltration,

Eligibility

Sex/Gender

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: - Male and female subjects aged> 18 at the time of enrollment - Chronic knee pain with VAS> 5 for more than 3 months - Condition after implantation of a knee endoprosthesis, condition after changing a knee endoprosthesis or clinically and radiologically confirmed gonarthrosis - Pain reduction through test infiltration <3 VAS points

Exclusion criteria

Exclusion criteria: - Infection or lower limb lymphangitis - Infiltration with corticosteroids or hyaluronic acid less than 3 months ago - Patients with pacemakers or other electrical implants

Design outcomes

Primary

Measure	Time frame
Documentation of the length of action of the denervation of the genicular nerve branches in chronic knee pain with recording of the pain intensity during the course. In particular, the time should be determined at which the pre-interventional pain intensity is reached again. The duration of action is examined via the VAS (visual pain scale) and the need for pain medication: pre-interventional, post-interventional, follow-up 3 months, 6 months and 12 months. The patient will also be given pain diaries. Patients should record the average pain intensity and pain reliever weekly on these protocols and submit the protocols every four weeks. If there are no returns, contact us by phone. With this close follow-up, a more precise determination of the point in time should be achieved, which reflects the pre-interventional pain intensity and a lost to follow-up should be avoided.	—
