SAN ANTONIO — Researchers discovered improved outcome scores at 3 years for patients with cartilage lesions of the knee who underwent mini arthrotomy and with bone marrow aspirate concentrate covered with a collagen I/III matrix.
“Biologic arthroplasty with this technique is a viable option,” John Lane, MD, said during his presentation at the Arthroscopy Association of North America Annual Meeting.
The investigators prospectively followed 25 patients who had patellofemoral defects up to 8.6 cm2 in average size. Of these patients, 18 had concomitant surgery and four required ACL reconstruction. All patients underwent X-rays and MRIs. The researchers recorded Visual Analog Scale, IKDC, KOOS, Lysholm, and Marx and Tegner scores at 12 months, 24 months and 36 months.
The patients improved in all outcome scores and showed good lesion coverage and tissue quality at final follow-up, Lane said. The researchers noted no complications at final-follow-up.
“[The procedure] is low cost,” Lane said. “We do need some long-term prospective trials.”
