Arthroscopic, partial humeral head resurfacing may improve outcomes in patients with chondral lesions
ORLANDO — Patients with severe focal, chondral lesions experienced significant improvements in clinical outcomes at 5 years with arthroscopic, partial humeral head resurfacing, according to results presented at the Arthroscopy Association of North America Annual Meeting.
Leo Pauzenberger, MD, PhD, and colleagues evaluated Constant score and American Shoulder and Elbow Surgeons scale score preoperatively and at 2 and 5 years postoperatively for 30 patients who underwent arthroscopically assisted, partial humeral head resurfacing (Partial Eclipse, Arthrex Inc.).
“The clinical scores improved significantly from pre- to postoperatively and this ... remained stable up to 5-year outcome follow-ups,” Pauzenberger said in his presentation here.
Pauzenberger added similar improvements in outcome scores among patients who received either a 25-mm diameter implant or a 30-mm to 35-mm diameter implant. Results showed significant improvement in external and internal rotation at 5-year follow-up. However, researchers found a 5-year survival rate of 87.7%, as there were four patients who had concomitant severe glenoid lesions at the time of initial surgery undergoing revision surgery for progressive glenohumeral degeneration.
“Pain significantly decreased from baseline,” Pauzenberger said. “They have some pain, but it remained low at 5-year follow-up and, as you see, [patients were] overall happy with the function of the shoulder.” – by Casey Tingle
