“…Six studies evaluated the effect of CAI surgical treatment using specific biomechanical parameters [44, 45, 48–51]. The proprioceptive function of the ankle joint was investigated in three studies, always using different functional tests [44, 48, 49].…”

Purpose Several evaluation modalities are reported in the literature dealing with the operative treatment of chronic ankle instability (CAI) both to establish the CAI diagnosis leading to the surgical indication and to assess the effectiveness of ankle stabilisation procedure. The purpose of this study is to present an overview of the pre-and postoperative evaluation modalities reported in the literature dealing with CAI operative treatment. The comprehensive analysis of the different modalities chosen by researchers is expected to suggest critical points in current evaluation ability of CAI surgical treatment. Methods Systematic review of the literature on surgical treatment of CAI through anatomic procedures. Pubmed, Embase and Cochrane electronic databases were analysed, from 2004 to 2018. Results One-hundred-and-four studies met inclusion in this systematic review. 88 out of 104 studies analysed preoperative mechanical laxity of the ankle to depict the ligamentous insufficiency related to the subjective feeling of functional instability. Stress radiographs and manual stress examination of the ankle were the two most common modalities to evaluate joint laxity, reported in 67 and 53 studies, respectively. Clinical Outcome Measurement Scales (COMs) is the most common evaluation modality (102 out of 104 studies) to assess CAI surgical outcome. The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot scale (AOFAS) and the Karlsson score are the most frequent COMs, reported in the 66% and 33%, respectively of the included literature. The radiographic analysis of ankle laxity after stabilisation procedures is the second most frequent postoperative evaluation modality, reported in 55 out 104 studies. Conclusions There is a lack of standardization among researchers related to both the criteria to establish the CAI diagnosis leading to the surgical indication and the modality chosen to evaluate the effectiveness of surgical treatment. Future standardization of evaluation modalities in the CAI population is desirable to increase consistency of reported data. Level of evidence Level IV, review of level I, II, III and IV studies.

“…Therefore, the authors believe that the recovery of slowly adapting mechanoreceptors may be insufficient through surgical repair alone 45 . Furthermore, Li et al reported that the muscle reaction times of dorsiflexion and eversion did not improve on electromyography (EMG) after MBP 46 , probably because the delayed muscle reaction time is not related to ligament injury or mechanical instability 47 . Given that the results of the present study were consistent with those of previous studies, we believe that proprioception and neuromuscular training should be considered postoperatively to improve muscular reaction time in dorsiflexion and eversion 45 , 48 , 49 .…”

The modified Broström procedure (MBP) is an initial treatment for symptomatic chronic ankle instability (CAI) patients. This study aimed to compare the proprioception and neuromuscular control ability of both affected and unaffected ankles at the time of return to sports after MBP for patients with scores of normal controls. 75 individuals (40 who underwent MBP, 35 normal controls) participated. The dynamic balance test scores were significantly higher in the affected ankle of the patients than in the controls (1.5 ± 0.6° vs. 1.1 ± 0.4°, p < 0.003). The time to peak torque for dorsiflexion (60.8 ± 13.9 ms vs. 52.2 ± 17.5 ms, p < 0.022) and eversion (68.9 ± 19.1 ms vs. 59.3 ± 21.1 ms, p < 0.043) was significantly delayed in the affected ankle of the patients than in the controls. The dynamic balance test and time to peak torque in CAI patients remained significantly reduced at the time of return-to-sport after MBP. Clinicians and therapists should be aware of potential deficits in proprioception and neuromuscular control when determining the timing of return to sports after MBP.

“…After lateral ligament repair, patients with LAI have increased peroneal strength and muscle endurance. However, this condition does not shorten the reaction times of the tibialis anterior and peroneus longus muscles [7, 9, 21, 22]. Neuromuscular remodelling occurred after arthroscopic MBP and microfracture.…”

Purpose A biomechanical study, in which imaging modalities are used to strictly include patients with concurrent lateral ankle instability (LAI) and osteochondral lesions of the talus (OLT), is needed to demonstrate the static and dynamic ankle range of motion (ROM) restriction in these patients, and determine whether ankle ROM restriction can be corrected postoperatively. Methods Eight patients with concurrent LAI and OLT treated with the arthroscopic modiied Broström procedure and microfracture were recruited from June 2019 to January 2020. Patients were assessed using outcome scales, static ankle ROM, and a stair descent gait analysis for dynamic ankle ROM, a day prior to surgery and one year postoperatively. Eight healthy subjects were assessed using the same modalities upon recruitment. Operative outcomes and variables during stair descent were documented and compared among the preoperative, postoperative, and healthy groups. A curve analysis, onedimensional statistical parametric mapping, was performed to compare the dynamic ankle kinematics and muscle activation curves over the entire normalised time series. ResultsThe functional outcomes of patients with concurrent LAI and OLT were signiicantly worse than those of healthy subjects preoperatively, but were partially improved postoperatively. Patients had decreased static and dynamic ROM preoperatively, and static ROM did not signiicantly increase postoperatively (
