Retrospective Study on the Comparison of the Efficacy of Ankle Arthroscopic Microfracture Surgery and Conventional Open Surgery in the Treatment of Osteochondral Injury of Talus
Objective:To compare the efficacy of ankle arthroscopic micro fracture surgery and conventional open surgery in the treatment of osteochondral injury(OLT)of talus.Methods:The clinical data of 90 OLT patients who were admitted to Beijing Ditan Hos-pital Affiliated to Capital Medical University from May 2017 to May 2021 were retrospectively analyzed.Patients were divided into group A(conventional open surgery,44 cases)and group B(ankle arthroscopic microfracture surgery,46 cases)according to the differ-ent surgical methods.The clinical indicators,visual analogue scale(VAS),American Orthopaedic Foot and Ankle Society(AOFAS)score,ankle dorsiflexion-metatarsal flexion activity,imaging evaluation results and complication rate were compared between two groups.Results:The intraoperative blood loss in group B was less than that in group A,and the operation time,walking time and full weight-bearing time were shorter than those in group A(P＜0.05).At the final follow-up,the VAS score in group B was lower than that in group A,the AOFAS score was higher than that in group A,and the ankle dorsiflexion-plantar flexion activity was greater than that in group A(P＜0.05).The modified Outerbridge grading and Kellgren-Lawrence grading ratio in two groups were improved at the last fol-low-up,and the improvement effect in group B was better than that in group A(P＜0.05).The incidence of complications in group B was lower than that in group A(P＜0.05).Conclusion:Compare with conventional open surgery,ankle arthroscopic microfracture surgery for OLT patients has better efficacy in restoring ankle function,relieving pain and promoting the rehabilitation process,and can also reduce the incidence of complications.
