Knee pain is the most common symptom of osteoarthritis (OA) in the knee. Osteoarthritis is more likely to develop as people age, making it painful to climb stairs, jog or kneel. Over time, osteoarthritis of the knee can change the shape of the knee joint, making it unstable or wobbly.

Because of OA, millions of knee replacement surgeries are carried out each year globally

Now, a California-based medical device company Moximed has offered a treatment option that could potentially delay arthroplasty (joint replacement surgery).

It’s like a mini shock absorber

Moximed’s MISHA™ Knee System is an implantable shock absorber (ISA) for the treatment of knee osteoarthritis by easing pain and maintaining function. The Misha knee system is implanted under the skin via a single incision, in an outpatient procedure. Once placed, it moves with the natural joint to lower peak forces on the knee by more than 30% with every walking step.

To assess the effectiveness and safety of the MISHA Knee System, the clinical study, which involved 81 participants, achieved its primary endpoint, demonstrated reduced pain scores, and improved function scores for participants.

Moximed CEO Anton Clifford said: “In our investigational device exemption (IDE) study, the MISHA Knee System was compared to the high standard set by high tibial osteotomy, a well-established orthopedic procedure.

“To demonstrate superiority against an established procedure, with proven results, is a great outcome for patients.”

It was found to be superior to high tibial osteotomy (HTO) with a composite success rate of 85.6%, compared to 65.5% by HTO.
