Error in Level of Evidence

Abstract

We have recently identified an error in the article by Gobbi et al. “Osteochondral Lesions of the Talus: Randomized Controlled Trial Comparing Chondroplasty, Microfracture, and Osteochondral Autograft Transplantation” (Arthroscopy 2006;22:1085-1092). The maximum time of patient follow-up was no more than 48 months. This, combined with the technique of pseudo-randomization described in our Methods and Discussion, suggests that the paper should be reclassified as Level II evidence. Thank you. Osteochondral Lesions of the Talus: Randomized Controlled Trial Comparing Chondroplasty, Microfracture, and Osteochondral Autograft TransplantationArthroscopyVol. 22Issue 10PreviewPurpose: The purpose of this study was to compare outcomes of chondroplasty versus microfracture versus osteochondral autologous transplantation (OAT) in patients with osteochondral lesions of the talus (OLT). Methods: After prospective sample size analysis, patients with symptomatic, recalcitrant Ferkel class 2b, 3, and 4 OLT were randomized to chondroplasty, microfracture, or OAT treatment groups. Outcomes were measured with use of the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale (AHS), the Subjective Assessment Numeric Evaluation (SANE) rating, Numeric Pain Intensity (NPI), and magnetic resonance imaging (MRI).
