Both Open and Arthroscopic All-Inside Anatomic Reconstruction With Autologous Gracilis Tendon Restore Ankle Stability in Patients With Chronic Lateral Ankle Instability

摘要

? 2022 Arthroscopy Association of North AmericaPurpose: To compare the return to sports and short-term clinical outcomes between the arthroscopic all-inside and the open anatomic reconstruction with gracilis tendon autograft for chronic lateral ankle instability (CLAI) patients. Methods: From March 2018 to January 2020, 57 CLAI patients were prospectively included with arthroscopic all-inside anatomic reconstruction (n = 31) or open anatomic reconstruction (n = 26) with gracilis tendon autograft. The patients were evaluated before operation and at 3 months, 6 months, 12 months, and 24 months after surgery. The American Orthopaedic Foot and Ankle Society score (AOFAS), visual analog scale (VAS), and Karlsson-Peterson score were evaluated at each time point, and stress radiography with a Telos device was performed before surgery and at final follow-up. The time to return to full weightbearing walking, jogging, sports, and work, Tegner activity score, and complications were recorded and compared. Results: All the subjective scores significantly improved after surgery from the preoperative level. Compared with the open group, the arthroscopic group demonstrated significantly earlier return to full weightbearing walking (8.9 vs 11.7 weeks, P .05). Conclusion: Compared with the open procedure, the arthroscopic all-inside anatomic lateral ankle ligament reconstruction with autologous gracilis tendon could achieve earlier return to full weightbearing, jogging, and recreational sports with less pain and better ankle functional scores at 3 to 6 months after surgery. Similar favorable short-term clinical outcomes were achieved for both techniques at 2 years after surgery. Study Design: Level I, randomized controlled trial.
