Osteochondral lesions of the talus (OLT) is a common and clinically challenging disease. The optimal management still under debate. purpose this prospective study was to investigate feasibility clinical outcomes autologous costal osteochondral transplantation (ACOT) for treatment cystic OLT.From November 2021 April 2023, five patients underwent OLT. demographic data described, including age, gender, lesion size location. We prospectively evaluated their functional imaging 12 months postoperatively, numeric rating score (NRS) pain when walking, Tegner score, American Orthopedic Foot & Ankle Society (AOFAS) Ability Measure (FAAM) results. A paired t-test used preoperative postoperative comparison paired-design dataset.The average age 36.6 ± 11.1 years. diameter chondral 14.95 2.71 mm, subchondral cysts 10.66 1.84 depth 10.40 1.86 mm. At function indexes improved significantly, NRS (from 5.2 2.3 0), 3.2 0.4 5.8 0.4), AOFAS 72.8 10.0 98.2 4.0), FAAM (FAAM/ADL from 61.2 24.7 99.3 1.6; FAAM/Sports 32.5 13.73 96.3 8.4). Their magnetic resonance observation cartilage repair tissue (MOCART) scores reached 78.0 7.6 points. ICRS three were nearly normal (10 or 11 points). biopsy surviving grafts showed plenty hyaline matrix scattered chondrocytes histologically. No major severe complications reported during follow-up.ACOT could significantly relieve symptoms with OLT improve at short-term follow-up. ACOT might be feasible useful method repairing cysts.
