A minimally invasive process supplies vital reduction from knee ache and should forestall the necessity for knee alternative surgical procedure in folks with osteoarthritis, in keeping with a examine being introduced this week on the annual assembly of the Radiological Society of North America (RSNA).
This examine addresses osteoarthritis, which is a major public well being concern and the main reason for persistent ache and incapacity worldwide. With tens of millions of individuals affected by knee osteoarthritis, notably in growing old populations, discovering efficient, minimally invasive therapies is important.”

Osteoarthritis, a persistent, degenerative and progressive situation, is the most typical reason for persistent joint problems. In keeping with the World Well being Group, knee osteoarthritis impacts over 365 million adults worldwide.
Most accessible therapies, equivalent to ache remedy and steroid injections, solely masks the signs of osteoarthritis. They do not sluggish development of the illness. As osteoarthritis worsens and conservative therapies grow to be ineffective, many individuals flip to joint alternative surgical procedure.
Genicular artery embolization (GAE) is an progressive minimally invasive remedy for sufferers with symptomatic knee osteoarthritis. The genicular arteries have a number of branches that kind a community across the knee joint. These vessels are altered in sufferers affected by osteoarthritis. In GAE, an interventional radiologist injects small particles into chosen branches that correspond to the positioning of knee ache to dam blood movement to that space. Embolization of the irregular blood vessels helps to disrupt the cycle of irritation, cartilage destruction and sensory nerve progress that characterizes osteoarthritis.
For the examine, Dr. Fleckenstein and colleagues performed a retrospective evaluation of 403 instances from sufferers (age 40 to 90) with reasonable to extreme knee osteoarthritis that did not reply to conservative therapies. All sufferers underwent GAE on the Charité – College Hospital Berlin. The examine was designed to judge each the protection and efficacy of GAE throughout a broad spectrum of osteoarthritis severities. The effectiveness of the process was measured utilizing the Visible Analog Scale and the Knee Harm and Osteoarthritis Final result Rating. These standardized scores, which measure ache and high quality of life, had been recorded at baseline and through follow-up visits at six weeks, three months, six months and one-year post-procedure.
Technical success was achieved in 100% of procedures. Short-term slight pores and skin discoloration and delicate knee ache instantly after the process had been famous in 18% of all instances. No extreme issues had been reported. The standard-of-life index and ache rating improved by 87% and 71%, respectively, at one-year follow-up.
The findings present that GAE is a protected and efficient therapy choice throughout all severity grades of knee osteoarthritis, together with superior instances the place different therapies have very restricted efficacy.
“Our examine discovered that GAE can successfully scale back knee ache and enhance high quality of life early after the therapy, with these advantages being maintained over the long run, particularly for individuals who have not had success with different therapies like bodily remedy or ache drugs,” Dr. Fleckenstein stated. “This might probably provide a brand new lease on life for a lot of sufferers that suffer from debilitating ache and mobility points, brought on by osteoarthritis.”
Nevertheless, the examine additionally confirmed that GAE is especially efficient within the early phases of knee osteoarthritis. This means that early intervention may probably delay and even forestall illness development, lowering the necessity for extra invasive therapies, equivalent to surgical procedure.
The researchers hope that by demonstrating the process’s success in a big and various affected person inhabitants, the examine may affect medical follow and coverage, encouraging broader adoption of GAE in medical settings worldwide.
“GAE has the potential to cut back the necessity for extra invasive surgical procedures, decrease well being care prices and considerably enhance the standard of life for numerous people affected by knee osteoarthritis,” Dr. Fleckenstein stated.
He and his workforce plan to proceed their analysis on degenerative joint problems to offer sufferers with new choices within the discipline of interventional radiology.
