FRANKLIN, Mass., Oct. 9, 2019 /PRNewswire/ -- A new study published in the Journal of Shoulder and Elbow Surgery reports that the OVO® with Inlay Glenoid Shoulder Arthroplasty System demonstrates excellent clinical benefits, including pain relief and increased range of motion in patients with glenohumeral (GH) arthritis. The OVO® with Inlay Glenoid Shoulder Arthroplasty System is made by Arthrosurface®, Inc., a global leader in joint preservation technology.

Shoulder Osteoarthritis (OA) treated with the nonspherical Arthrosurface OVO with Inlay Glenoid Arthroplasty System. New data demonstrates excellent clinical benefits, including pain relief and increased range of motion in patients with glenohumeral (GH) arthritis. Allows patients to resume an active lifestyle with no activity restrictions.

"Our initial results show that nonspherical HH [humeral head] resurfacing, combined with inlay glenoid replacement, is a viable outpatient technique for GH arthritis across patients with concentric and eccentric glenoid morphology," the study states. "Results showed no significant differences in patient-reported outcomes including pain relief, function and satisfaction, comparing preoperative concentric with nonconcentric glenoid morphology. We found a significant improvement in range of motion that was consistent across glenoid stages."

The study, conducted by the Department of Orthopedic Surgery at The Cleveland Clinic Foundation, involved a retrospective case series including 31 shoulders in 29 patients, with an average age of 58.5 years old. Osteoarthritis (OA) of the GH joint can be a disabling condition resulting in pain and loss of function. According to the Arthritis Foundation, it is estimated that nearly 1 in 3 people over the age of 60 have shoulder OA to some degree. Positive outcomes of the study included significant improvement in Penn Shoulder Score, improved range of motion when compared to traditional stemmed total shoulder arthroplasty (TSA) in conventional and reverse configurations, patient pain relief and functional results for both eccentric and concentric glenoids.

"This truly is a revolutionary stemless total shoulder, which combines the concept of anatomic restoration with an aspherical head design that more closely replicates the normal patient anatomy," said Dr. Anthony Miniaci, MD of the Cleveland Clinic. "This combination of an aspherical head and inlay glenoid has shown to be effective in not only active and younger patients but in those with glenohumeral arthritis, even in the face of posterior subluxation and bone erosion."
