This prospective Level IV study tested a one-step arthroscopic technique for talar osteochondral lesions. Concentrated bone marrow-derived cells were combined with a scaffold (collagen powder or hyaluronic acid membrane) and platelet gel in a single operation. The goal was to repair cartilage and subchondral bone without the two-stage surgery and cell culture required by autologous chondrocyte implantation.
For a chronic Type II talar osteochondral lesion in a young athlete, this paper offers a one-operation alternative to autologous chondrocyte implantation.
The mental model: transplant the whole marrow concentrate plus platelet gel, and the multipotent cells plus their niche regenerate both cartilage and subchondral bone in a single arthroscopic session. This sidesteps the cell-culture step, the second surgery, and the high cost of ACI.
When counseling patients, remember that lesion area drives prognosis, not depth. Larger lesions above 2 to 3 cm² do worse, and prior failed surgery starts patients at a lower baseline.
Be honest about the tissue: histology showed fibrocartilage with variable remodeling, not true hyaline cartilage, and this is a Level IV series with no control group, only three biopsies, and short 2-year followup. Durability remains unproven.
