“…This method was also adopted in our numerical analysis. The model was validated by comparing the results of our numerical analysis with previous experimental data [4,13].It was found that the inversion and external rotation of the subtalar joint in the intact/instability model under a torsional moment of 4 Nm were consistent between our simulation and Pellegrini's experiment (Table 4). The inversion under 1.5Nm and the internal rotation under 3Nm of the subtalar joint in our simulation were close to Choisne's results (Table 5).…”

“…An FE model of subtalar instability was developed based on one of our previous studies [15]. The subtalar instability was simulated by removing the CFL, ITCL and CL, as suggested by a previous cadaveric study [13]. Due to the fact that subtalar instability rarely occurs alone, the ATFL was also removed before performing the analysis of Schon triligamentous reconstruction and Mann triligamentous reconstruction.…”

Background: There are several types of tenodesis reconstruction designed for subtalar instability.However, no comprehensive comparison has been conducted among these procedures in terms of their correcting power so far. The objective of this study is to evaluate the biomechanical behaviors of 5 representative procedures through finite element analysis. Methods: A finite element model was established and validated based on one of our previous studies. The Pisani interosseous talocalcaneal ligament(ITCL) reconstruction, Schon cervical ligament(CL) reconstruction and Choisne calcaneofibular ligament(CFL)reconstruction were compared on a model with the CFL, ITCL and CL sectioned. The Schon triligamentous reconstruction and Mann triligamentous reconstruction were compared on a model with the CFL, ITCL and CL, as well as the anterior talofibular ligament (ATFL) sectioned. The inversion and external/internal rotation were quantified in different ankle positions with rotational moment.Results: For single ligament reconstruction, the Choisne CFL reconstruction provided the greatest degree of correction for subtalar instability, followed by the Schon CL reconstruction and then the Pisani ITCL reconstruction. For triligamentous reconstruction, the Mann procedure outperformed the Schon procedure in alleviating the subtalar instability. Conclusion:The finite element analysis showed that the Choisne CFL reconstruction and Mann triligamentous reconstruction provided the greatest degree of immediate postoperative subtalar stability. However, both procedures could not restore the biomechanical behaviors of the subtalar joint to normal. The long-term efficacy of these procedures warrants further investigation using a substantially larger sample of clinical cases.

“…During the foot strike of stair descent, the foot was loaded and excessively plantar‐flexed, predisposing the foot to increased risk of ankle sprain. The calcaneofibular ligament section in cadaveric studies was associated with increased tibiotalar and subtalar inversion; however, with a plantar‐flexed foot, reconstruction of the calcaneofibular ligament could not refrain tibiotalar inversion . When the foot is plantar‐flexed, the anterior talofibular ligament is a more important structure to refrain excessive inversion .…”

“…The ligamentous structure is important in subtalar stability. The calcaneofibular ligament is associated with both tibiotalar and subtalar joint inversion/eversion stability . A carefully designed in vitro study reported increased subtalar inversion and external rotation after calcaneofibular ligament sectioning .…”

“…Non‐anatomical lateral ligament reconstruction failed to restore the physiological kinematics in subtalar joints . In vitro biomechanical studies suggested better subtalar stability was achieved after modified Brostrom–Gould procedure compared with anatomical calcaneofibular ligament reconstruction . If FAI patients are refractory of non‐operative treatment, operative treatment such as modified Brostrom–Gould procedure would also help.…”

Patients with mechanic ankle instability experience increased tibiotalar and subtalar joint laxity. However, in vivo joint kinematics in functional ankle instability (FAI) patients and lateral ankle sprain (LAS) copers, especially during dynamic activities, are poorly understood. Ten FAI patients, 10 LAS copers, and 10 healthy controls were included in this study. A dual fluoroscopic imaging system was used to analyze the tibiotalar and subtalar joint kinematics during stair descent. Five key poses of stair descent were analyzed. Kinematic data from six degrees of freedom were calculated utilizing a solid modeling software. The range of motion and joint positions in each degree of freedom were compared among the three groups. The tibiotalar joints of FAI patients and LAS copers were significantly more inverted than those of healthy controls during the foot strike (p = 0.016, η p 2 = 0.264). The subtalar joints of FAI patients were significantly more anteriorly translated (pose 2, p = 0.003, η p 2 = 0.352; pose 3, p < 0.001, η p 2 = 0.454; pose 4, p = 0.004, η p 2 = 0.334), inverted (pose 4, p = 0.027, η p 2 = 0.234; pose 5, p = 0.034, η p 2 = 0.221), and externally rotated (pose 4, p = 0.037, η p 2 = 0.217; pose 5; p = 0.004, η p 2 = 0.331) than those of healthy controls during the mid-stance and the heel off. The FAI patients showed excessive tibiotalar inversion and subtalar joint hypermobility during stair descent. Meanwhile, the LAS copers maintained subtalar joint stability, and only showed excessive tibiotalar inversion in foot strike. These data provide insight into the mechanisms behind the development of FAI after initial LAS.
