TAPE & Joint embolization in Karlsruhe

A possible supplement for selected chronic joint pain.

Joint embolization may be considered for selected chronic joint symptoms. It targets abnormal small vessels in painful joint regions. The method does not replace a careful orthopaedic diagnosis and must be assessed in the context of the underlying condition.

Request a consultation about joint embolization / TAPE Bones and soft tissues: overview

Definitions: GAE at the knee · TAPE as the broader term
Objective: Reduce complaints if appropriately selected
Classification: Long-term benefit and patient selection further under investigation

Who may be suitable for joint embolization?

Persistent knee pain can have many causes. Before a decision, complaints, examination, Medical imaging and previous therapies are therefore considered together. Of particular importance is whether conservative measures have been sufficiently used and whether different treatment is a priority.

At the clinic Karlsruhe the Joint embolization is described as part of the treatment options for knee complaints. The offer was also presented at a joint patient event by orthopaedics and radiology.

What do GAE and TAPE mean?

GAE means genicular artery embolization: embolization of vessels at the knee. TAPE stands for transarterial periarticular embolization and describes the broader approach to vessels near a joint. These terms do not describe identical treatment at every joint.

A catheter is used to reach suitable small vessels under image guidance and embolize them selectively. The aim is to relieve symptoms. The procedure does not regenerate worn cartilage.

How robust is the scientific basis?

The Joint embolization is a procedure in further scientific evaluation. The UK assessment institution NICE assesses the evidence on efficacy and long-term safety in knee osteoarthritis as not yet sufficient and recommends its application in the research context.

This assessment is not a German approval rule. Evidence and clinical practice are also being discussed in Germany; DeGIR published a statement in 2026. Potential benefits, uncertainties and alternatives must be discussed openly. Results for one joint condition cannot be applied to every other cause of pain.

Alternatives, risks and course

Physical therapy, movement therapy, an adapted pain treatment and, if necessary, surgical procedures remain part of the treatment. One Embolization is not a blanket replacement for a medically necessary joint replacement.

The discussion includes bleeding at the access site, reactions to contrast agents, radiation exposure and unintended reduction of blood flow outside the target area. Treatment may also provide no improvement or only temporary improvement.

After treatment, pain, mobility and everyday function must be assessed in the course. Further orthopaedic care and appropriate exercise therapy remain important.

Frequently asked questions to Joint embolization / TAPE

What does TAPE mean for joint pain?

TAPE stands for Transarterial periarticular embolization: a catheter treatment of vessels close to the joint. It is not a treatment with glued kinesio tapes. Appropriateness is determined after orthopaedic and radiological assessment.

Can one Joint embolization cure osteoarthritis?

No. It aims at a possible alleviation of the complaint and does not restore lost articular cartilage. Whether it makes sense depends on the individual situation.

Is the procedure equally well studied for all joints?

No. The data differs depending on the joint, disease and technology. Therefore, the significance of the studies for your specific question is discussed.
