Objective To investigate and analyze the clinical characteristics and epidemiology of 188 hospitalized patients with osteochondral lesions of the talus (OLT), in order to provide a reference for the clinical prevention and treatment of OLT.Methods The medical records of OLT patients admitted to the department of foot and ankle surgery, Beijing Jishuitan Hospital, Capital Medical University, from March 2018 to March 2021 were retrospectively analyzed, and the basic information of the patients, the cause of the injury, the location and size of the lesion, the operation method, and the follow-up data (outcomes) were collected. Comparison was made according to different surgical methods.Results A total of 188 hospitalized OLT patients were included in this study. There were 130 males (69.1%) and 58 females (30.9%). The incidence peak was near the age of 18-40 years, reaching 138 cases (73.4%). There were 144 cases (76.6%) with a BMI value greater than 25 kg/m2; the average course of disease was (29.1±7.8) months. There were 160 traumatic cases (85.1%) and 28 cases with degenerative injury(14.9%), 142 cases (75.5%) of medial injuries and 46 cases (24.5%) of lateral injuries; 84 cases (44.7%) with left ankle and 104 cases (55.3%) with right ankle; 75 cases (39.9%) of Hepple Ⅰ-Ⅱ type, 113 cases of Hepple Ⅲ-Ⅴ type and of whom 115 cases (61.2%) had lesions larger than 1.5 cm2. According to Hepples MRI classification, there were 67 patients (35.6%) were treated with microfracture surgery(microfracture group), 84 patients (44.7%) were treated with autologous osteochondral transplantation (autologous osteochondral transplantation group) and 37 patients (19.7%) were treated with periosteal iliac bone transplantation (periosteal iliac bone transplantation group). At 18 months after operation, the AOFAS scores of the autologous osteochondral transplantation group and the periosteal iliac bone transplantation group were significantly higher than those of the microfracture group, whereas the VAS scores were significantly lower than those in the microfracture group, with statistical differences (P<0.05).Conclusion The majority of OLT patients admitted to the unit treated by the author were traumatic injuries, which tend to occur in young and middle-aged people. There were more males than females, with more medial injuries than lateral ones. Hepple Ⅲ-Ⅴ injuries are recommended for surgical treatment. |
