ABSTRACT
OBJECTIVE@#To explore the clinical efficacy of reconstruction the anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon for the treatment of chronic lateral ankle instability.@*METHODS@#The clinical data of 42 patients with chronic lateral ankle instability treated by anatomical reconstruction of anterior talofibular ligament and calcaneofibular ligament with autologous peroneus brevis tendon from July 2016 to July 2019 was retrospectively analyzed. Including 30 males and 12 females, age ranged from 25 to 46 years old with an average of (37.6±12.4) years. There were 15 cases of left foot and 27 cases of right foot, the time from injury to operation was 3 to 12 months with a mean of (7.4±2.8) months. And 14 patients had tenderness in lateral collateral ligament area, 28 patients complained of multiple ankle sprains while walking on the flat ground. At 12 months after operation, the talar tilt angle and visual analogue scale(VAS)were observed, ankle joint varus stress and anterior drawer test were performed to check the mechanical stability of the ankle joint, American Orhopaedic Foot and Ankle Society(AOFAS) was used to score the ankle and hindfoot functions and evaluate the curative effect.@*RESULTS@#Forty patients were followed up for 12 to 48 months with an average of (28.3±10.0) months, 2 cases were lost. The VAS decreased from(4.50±0.93) scores before surgery to (1.10±0.30) scores at 12 months after surgery;the talar tilt angle was reduced from (12.26±1.13)° before operation to (4.60±0.45)° at 12 months after operation;the AOFAS score increased from (65.10±7.50)scores before surgery to (84.40±3.95) scores at 12 months after surgery;all the differences were statically significant(P<0.05). According to the AOFAS score, 27 cases got excellent results, 7 good, 5 fair, and 1 poor. One patient had the symptoms of sural nerve injury after operation, and the symptoms were relieved after oral Mecobalamin for 3 months. The remaining patients had no complications such as nerve injury, infection, and skin necrosis. There was no instability of ankle joint, and both ankle varus stress test and drawer test were negative.@*CONCLUSION@#Autologous peroneal brevis tendon with double bone channel pass through the tendon (modified Chrisman-Snook operation) can anatomically reconstruct the anterior talofibular ligament and the calcaneofibular ligament, restore the stability of the patient's ankle joint, reduce postoperative complications, and restore ankle joint function well.

Purpose To clarify the morphological parameter and describe the distance from the insertion of the lateral ankle ligaments to the adjacent bony landmarks through precisely anatomical explore of human cadaveric ankles,so as to provide anatomical evidences for the reconstruction of lateral ankle ligaments.Methods Nineteen ankle specimens were dissected to isolate the lateral ankle ligaments and measure the morphological parameters such as length,width,thickness and the distance from the insertion of the lateral ankle ligaments to the adjacent bony landmarks.Results The average length of anterior talofibular ligaments (ATFL) was 23.1 ± 2.98 mm,among which 8 were single-banded(42.1％)and 11 were double-banded(57.9％).The average distance from the fibular origination of ATFL to the anterior tubercle of fibula(AA)was 17.1 ± 3.00 mm,to the fibular obscure tubercle(AO)was 5.1 ± 1.69 mm,to the tip of the fibula(AT)was 14.1 ± 2.86 mm.The distances from the talus insertion of ATFL to the superior and inferior talus articular surface were 11.4 ± 2.25 mm and 18.4 ± 2.30 mm respectively,to the anterior lateral talus chondral surface was 4.8 ± 1.42 mm.The average length of calcaneofibular ligament(CFL)was 31.4 ± 3.55 mm.The average distance of the fibular origination from ATFL to CFL was 6.4 ± 2.55 mm.The average angle between ATFL and CFL was 116.6 ± 12.69°.The distance from the calcaneus insertion of CFL to the peroneal tubercle(CP)was 15.4 ± 2.86 mm,to the posterior superior border of calcaneus(CC)was 13.9 ± 2.46 mm,to the subtalar joint surface was 15.2 ± 3.21 mm.The coefficient variation assessing the anatomical reliability of different bony landmarks were as follows:ATFL fibular origination AA(17.54％) ＜AT(20.28％) ＜ AO(33.14％),CFL calcaneus insertion CC(17.70％)＜CP(18.57％)＜CS(21.1％).Conclusion Certain variations exist in the morphological parameters and the distances from the insertion of the lateral ankle ligaments to the adjacent bony landmarks.It provides anatomical evidence for lateral ankle ligament reconstruction in treating chronic ankle instability.
ABSTRACT
The lateral ankle ligaments consisted of the anterior talofibular, posterior talofibular and calcaneofibular ligaments. This study was to investigate the dimensions and anatomic variations of these ligaments and correlate with MR images. Sixty seven ankles of Korean adults were used. Among these 37 ankles were only disseted and 30 ankles were dissected after getting MR images. The anterior talofibular ligament consisted of two bands in 72.4%. The length and thickness of this ligament were 20.9mm and 1.8mm, respectively. The widths were 7.0 mm in the upper band and 4.7 mm in the lower band. The talofibular ligament appeared as a hypointense thick band or several lines in MR images. This ligament was observed in 100% of the axial MR sections and 82.8% of the coronal sections. The posterior talofibular ligament showed single thick band in 53.2% while others showed as two bands. The length, width, thickness and the angle between the horizontal plane and the posterior talofibular ligament were 21.8 mm, 7.3 mm, 3.4 mm and 22.6degrees, respectively. In coronal MR images this ligament appeared as a hypointense and heterogeneous thick band between the lateral malleolus and the talus. All anterior and posterior talofibular ligaments were observed in axial MR images with at least one same MR plane showing the two ligaments together. The length, width and thickness of the calcaneofibular ligament were 25.3 mm, 5.2 mm and 2.3 mm, respectively. It was composed of two bands in 8.5%. The angles to the coronal and sagittal planes and this ligament were 20.7degrees(range 5degrees~60degrees) and 27.0degrees(range 7degrees~50degrees), respectively. The calcaneofibular ligament was seen as a hypointense short line or dot depending on the cut plane. It was observed in 72.4% of the axial MR images and in 75.9% of the coronal images but was better imaged in the coronal planes.

Recurrent dislocation of the peroneal tendon is infrequent but often the injury is a disabling one, and the result of conservative treatment is unsatisfactory. Dislocation of these tendons may be the result of a congenitally shallow groove in the lateral malleolar or of a complete abscence of the groove and the dislocation may be present at birth or may be caused by trauma. We are reporting one case of bilateral recurrent dislocation of the peroneal tendons with- out any history of trauma in which disturbed superior peroneal retinaculum was reconstructed by transposition of the calcsneofibular ligament to the lateral side of the peroneal tendons. The calcaneal insertion of the calcaneofibular ligament was mobilised with a small bone block and reinserted in its bed after the transposition. After a follow up of 13 months, the result was satisfactory.
