Dear Editor:

We read with interest the article by Jiang and colleagues titled ‘‘Comparative Study on Immediate Versus Delayed Meniscus Allograft Transplantation: 4- to 6-Year Follow-up,’’ and we would like to express our comments to the authors. In this paper, the authors describe their clinical outcomes after immediate and delayed meniscus allograft transplantation (MAT). Patients in the immedi- ate study group (IM) underwent MAT immediately after total meniscectomy, while those in the delayed study group (DE) underwent MAT after the report of knee symptoms mean time, 35 months after total meniscectomy (range, 9-92 months); both groups were compared to a control group of patients undergoing meniscectomy (ME). The authors reported significantly improved outcomes in the IM group compared to the DE group with respect to Inter- national Knee Documentation Committee (IKDC) scores (mean, 93; range, 85-99 vs mean, 74; range, 38-95; P \ .05) and with respect to cartilage degeneration via radio- graphic/MRI analysis. Of note, there were no significant differences between any of the groups with regard to Lysholm score, Tegner score, joint narrowing, or meniscus extrusion.
