Radiographs showing the weight-bearing anterior-posterior (AP) views at baseline (ac) and 1 year after injection (df). Radiographs of a 59-year-old man revealing a progression of knee osteoarthritis (OA) from Kellgren-Lawrence (K-L) grade 1 at baseline (a) to K-L grade 2 at 1 year after hyaluronic acid (HA) injection (d). Radiographs of a 64-year-old woman demonstrating an advancement of knee OA from K-L grade 2 at baseline (b) to K-L grade 3 at 1 year after mesenchymal stem cell (MSC) injection (e). Radiographs of a 62-year-old woman depicting a deterioration of knee OA from K-L grade 3 at baseline (c) deteriorating to K-L grade 4 at 1 year after HA injection (f)
