Abstract:
OBJECTIVE:To evaluate clinical effect of autogenous iliac bone graft in treating osteochondral lesion of the talus with subchondral cyst.
METHODS:Twenty-two osteochondral lesion of talus patients with subchondral cyst were collected from January 2011 to December 2014, including 18 males and 4 females aged from 34 to 58 years old with an average of (46.4± 6.9) years old. All patients manifested pain and swelling of ankle joint, 7 patients manifested partially limited activity of ankle joint, 2 patients manifested unstable of ankle joint, and 2 patients manifested poor force line of foot. All lesions located on the medial side of talus dome. The area of cartilage injury ranged from 64 to 132(101.6±27.1) mm2, and diameter of subchondral cyst ranged from 9 to 15(10.5±1.8) mm. VAS score and AOFAS score were used to evaluate pain releases and recovery of ankle joint function before operation, 12 and 24 months after operation. Healing condition of autograft was assessed under arthroscopy after removal of internal fixation at 1 year after operation.
RESULTS:All patients were followed up from 24 to 60 months with an average of(42.5±9.9) months. Postoperative MRI at 12 months showed autograft healed well but little cyst still seen. Bone grafting and talus healed well, and formation of fibrocartilage well under arthroscopy. Postoperative MRI at 24 months showed combination of bone grafting and surrounding bone well, and small cyst could seen but less than before. VAS score at 12 months after operation 2.8±0.8 was less than that of before operation 6.2±1.5, but had no differences compared with 24 months after operation 2.6 ±0.8 (>0.05). AOFAS score at 12 months after operation 83.0±5.6 was less than that of before operation 55.3±13.7, but had no differences compared with 24 months after operation 83.7±6.6(>0.05).
CONCLUSIONS:Autogenous iliac bone graft in treating osteochondral lesion of the talus with subchondral cyst could have a good synosteosis and fibrous cartilage on surface, and relieve clinical symptoms.
