“…This finding can be attributed to the quasi‐static weight‐bearing methods used in previous studies, which did not create dynamic plantar‐flexed foot position. Anterior talofibular ligament injury causes an increased anterior translation in the tibiotalar joint . Neither excessive tibiotalar anterior translation nor external/internal rotation hypermobility was detected in the current study.…”

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.

“…This ankle arthrometer has previously been used to quantify the diagnostic validity of different subgroups in subjects or patients with CAI (Lohrer et al, 2015). Specifically, at low levels of force application deformation or stiffness measures are known to best distinguish between the tibiotalar translation and the rigidity of the ankle and its encompassing soft tissues with the talus already anteriorly translated to its end position (Kovaleski et al, 2014;Nauck et al, 2010;Tohyama et al, 2003).…”

Following an initial ankle sprain it is not unlikely that chronic ankle instability (CAI) will develop. CAI is associated with impaired perceived functional and mechanical properties of the ligaments. Nutritional supplementation with collagen peptides has been shown to improve the functional and mechanical properties of the connective tissue. The purpose of this study was to investigate the effectiveness of specific collagen peptide supplementation (SCP) to improve ankle stability in athletes with CAI. 50 male and female athletes with CAI completed a randomized, double-blinded and placebo-controlled study with a daily oral administration of either 5 g SCP or 5 g placebo (Maltodextrin) over a period of six months. Both, the Cumberland Ankle Instability Tool (CAIT) and the German version of the Foot and Ankle Ability Measure (FAAM-G) were used to measure the subjective perceived function of the ankle. Additionally, the mechanical stability was determined by measuring the ankle stiffness by an ankle arthrometer. Finally, a three-month follow-up was performed. ANOVA analysis indicated that the subjective ankle stability was improved in both the CAIT (p < 0.001) and the FAAM-G (p < 0.001) following SCP supplementation compared with placebo. No significant changes between the groups were detected in the results of the ankle arthrometer. After six month the subjective report of the ankle stability function significantly improved and the three month follow-up revealed a significant decline in the number of ankle joint injuries (p < 0.05). These data support the concept that specific collagen peptide supplementation in athletes with chronic ankle instability results in significant improvements in subjective perceived ankle stability. The reduction in the re-injury rate of ankle sprains in the follow-up period suggests that these findings have clinical relevance.

“…Force as well as anterior translation were measured with embedded sensors at a frequency of 100 Hz. Previous research indicates that ankle instability can best be differentiated at low levels of force application . The very early phase of force application below 20 N was not considered for data analysis, because it is suggested that in this range rather a soft‐tissue compression would be measured than a ligamentous contribution to joint stability .…”

“…Consequently, already in the 1980 researchers could show that sectioning the ATFL in cadavers increased the anterior translation of the ankle . Further studies could replicate these results and identify that only a relatively low amount of force is needed to elicit differences between intact and sectioned ligament conditions …”

A new instrumented device was developed to quantify ankle joint stability during an anterior talar drawer test. The aim of the present study was to validate this device comparing bone kinematics with arthrometer measurement outcomes. An anterior talar drawer test was performed with 14 cadaver legs using a custom instrumented ankle arthrometer. Using clusters of bone-pin markers, the relative three-dimensional movement of calcaneus, talus, and fibula was simultaneously measured. Anterior drawer test was applied on the intact foot and after sequentially sectioning the anterior talofibular ligament, the calcaneofibular ligament, and the posterior talofibular ligament. Cutting the anterior talofibular ligament caused a significant increase in bone-pin measured anterior translations of calcaneus and talus as well as in the anterior translation of the arthrometer. Analysis of receiver operating characteristic curves indicates a fair to good ability to discriminate between the intact and the sectioned conditions with the arthrometer. Distal distraction, inversion, and internal rotation movements were observed when two and three ligaments were cut. Results revealed that the ankle arthrometer was sensitive to detect changes in bone-to-bone movements during an anterior talar drawer test, when the anterior talofibular ligament was sectioned. Presumably due to movements in additional planes of motion, the arthrometer was not able to differentiate between situations with one or more ligaments cut. In conclusion, the instrumented anterior talar drawer tester may augment current procedures in assessing ankle instability primarily caused by ruptures of the anterior talofibular ligament.
