This is a Level 4 case series of 50 patients with chronic osteochondral lesions of the talus treated arthroscopically, mostly by excision and drilling. It asks whether arthroscopic treatment gives durable long-term results and which staging system best predicts outcome. Mean follow-up was 71 months.
The central teaching point: in chronic talar OLT, the arthroscopic appearance of the cartilage predicts outcome better than any preoperative scan. When you see a stable, intact surface (Ferkel/Cheng grades A-C) expect good results. When you see a flap, exposed bone, or a loose fragment (grades D-F) counsel the patient that persistent pain is more likely.
Imaging still earns its place. Plain films are often normal, so CT or MRI is needed to make the diagnosis, but do not use the imaging stage to predict how the patient will do. Management framework: try 4 to 6 months of conservative care first (though only about 45% respond), then arthroscopic excision and drilling or microfracture for most lesions.
Reserve osteochondral grafting or ACI for large cystic defects greater than 6 mm deep or for failed marrow stimulation. Finally, set realistic expectations. Results are good in the majority but a third deteriorate over years, likely because marrow-stimulation produces less durable type I fibrocartilage.
