Abstract:
Objective:To investigate the efficacy of osteochondral fragment fixation using bioabsorbable pins for Hepple Ⅱ osteochondral lesions of the talus (OLT) in adolescents.Methods:Retrospective case analysis was used. The clinical data and follow-up results of 13 adolescent patients (13 feet) with Hepple Ⅱ OLT were all treated with osteochondral fragment fixation using bioabsorbable pins admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2017 to December 2021 were retrospectively analyzed. There were 7 males and 6 females, with 13 right feet. The age was (14.85±2.23) years old, ranged from 12 to 18 years old. According to the American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) and SF-36 score before operation and at the last follow-up were used to evaluate the efficacy and function of the patients. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; The mearsurement data with skewness distribution were expressed by M( Q1, Q3), and rank-sum test was used for inter-group comparison. Results:Thirteen adolescent patients (13 feet) with Hepple Ⅱ OLT underwent surgery successfully and were followed up for (25.54±9.95) months. All wounds healed by first intention, and no complications such as wound infection and delayed healing occurred. Preoperative AOFAS ankle-posterior foot score, VAS and SF-36 score were 58.62±3.55, 7.00 (6.50, 8.00) and 68.38±4.81, respectively. At the last follow-up, the scores were 97.38±2.73, 1.00 (0.00, 1.00), 91.15±4.28, respectively, and the results were significantly improved at the last follow-up, with the difference between the two groups statistically significant( P<0.05). Conclusion:Osteochondral fragment fixation using bioabsorbable pins which can promote cartilage repair, significantly improve symptoms, and achieve better clinical satisfaction with fewer complications, is a safe and effective surgical treatment option for Hepple Ⅱ OLT in adolescents with satisfactory short-term clinical outcomes.
