Knee Cartilage Defects: Biologic Resurfacing Versus Focal Me
Researchers from Rush University Medical Center and the University of Colorado have compared several biological procedures when it comes to treating full thickness defects of the femoral condyle. The study, published in the February edition of Arthroscopy, was entitled, “A Comparison of the Outcomes for Cartilage Defects of the Knee Treated With Biologic Resurfacing Versus Focal Metallic Implants.”

The authors wrote, “A total of 61 patients met the selection criteria resulting in 30 patients treated with biological procedures, including debridement, microfracture, osteochondral autograft transplantation, osteochondral allograft, and autologous chondrocyte implantation (BIO group), and 32 patients treated with focal metallic resurfacing (CAP group)…Thirty patients in the BIO group had an average follow-up of 2.6 years and 32 patients in the CAP group were followed for 2.0 years. Fifty-three percent in the BIO group and 75% in the CAP group achieved success per the endpoint definition. The mean total WOMAC score improved significantly for both groups. The physical component score (Short Form-12 PCS) improved significantly in the CAP group only. Good to excellent patient satisfaction was achieved by 80% in BIO and 91% in CAP…”
