ABSTRACT
Objective To evaluate the clinical efficacy and safety of all-inside arthroscopic repair of anterior talofibular ligament(ATFL) for chronic lateral ankle instability(CLAI).Methods From October 2016 to September 2017,19 patients with CLAI were treated with all-inside arthroscopic repair of ATFL at Department of Orthopaedic Surgery,Zhejiang Provincial People's Hospital and Department of Foot and Ankle Surgery,Guangzhou Orthopaedic Hospital.They were 12 men and 7 women,aged from 18 to 35 years(mean,27.3 years).Their defective ATFLs had no effective tension.After the fibular foot-print zone of ATFL was refreshed,an absorbable anchor was inserted accurately and its suture was threaded into the remnant of ATFL using the all-inside arthroscopic technique.The remnant of ATFL was fixated by the suture using Lasso-Loop method and anatomically repaired into the foot-print zone to restore the ligamentous tension.The American Orthopedic Foot and Ankle Surgery Society(AOFAS) ankle-hindfoot score,Karlsson ankle function score,Tegner activity score and visual analogue scale(VAS) were used to assess funtion of ankle before and after operation.Results All the 19 patients were followed up for a mean time of 15.6 months(from 12 to 22 months).Their ankle symptoms were all relieved after operation;their ankles recovered fine range of motion;their anterior drawer tests and varus stress tests were negative.Their preoperative AOFAS scores(64.6±11.4),Karlsson ankle function scores(63.5±11.4),Tegner activity scores(3.2±0.7) and VAS(5.8±1.7) were significantly improved at the final follow-up(92.3±3.2,91.2±4.4,5.7±0.6 and 1.4±1.0,respectively)(P<0.05).complications such as incision and articular infections,superficial peroneal nerve injury,sural nerve injury and iatrogenic fracture were not demonstrated in the cohort.By the final follow-up,no patient had been found who needed a secondary revision.Conclusions The all-inside arthroscopic repair of ATFL can be used effectively and safely for CLAI,because it leads to accurate anchor insertion,anatomic repair,limited invasion,and reliable restoration of ligamentous tension.To avoid complications,surgeons should familiarize themselves with arthroscopic procedures.
