ABSTRACT Injuries to the lateral ankle ligaments are quite common, with a reported incidence of up to 22% of all sports injuries, and 85% of all ankle sprains. Most of these are effectively managed using nonoperative measures in the acute setting. Approximately 20% of patients will, however, develop chronic lateral ankle instability (CLAI). Although the anatomy and biomechanics are well documented, more recently, the concepts of the lateral talofibular calcaneal ligament (LTFCL) and microinstability have been described. For those who develop CLAI, a full assessment is mandatory to not only search for correctable risk factors (malalignment), but also to differentiate between functional and mechanical instability. Associated injuries need to be excluded, such as osteochondral lesions of the talus. Rotational ankle instability is a new concept that needs to be considered. Patients who present with CLAI are initially managed conservatively in the form of functional rehabilitation. This management is especially effective in patients with functional instability. Surgery is generally indicated after failed conservative management in patients with objective mechanical instability. The elite athlete is a relative indication to performing surgery early. The choice of surgical procedure is made on an individualised basis, although open anatomical procedures remain the gold standard. Non-anatomical procedures are no longer recommended. Newer minimally invasive and endoscopic techniques show promise in experienced hands but there is only limited evidence to support its use at present. The use of a suture tape as an augment is reserved for specific indications and should not be used routinely.

Talar Tilt

Background: Osteochondral lesion of the talus (OLT) is commonly found as a concomitant pathologic lesion in a large proportion of patients with chronic lateral ankle instability (CLAI). This study investigated which characteristics in a patient with CLAI increase the risk for OLT. Methods: Three hundred sixty-four patients who underwent a modified Broström operation for their CLAI were reviewed retrospectively. The characteristics of each patient and variables associated with OLTs were investigated. Statistical analyses were performed to determine the effect of each potential predictor on the incidence of OLT, and to evaluate the associations between the patient characteristics and variables associated with OLTs. Results: Patients with OLTs were more frequently female (female vs male: 63.1% vs 43.9%, P = .003). In addition, the lesion sizes were larger in female patients (female vs male: 113.9 ± 24.9 mm2 vs 100.7 ± 18.0 mm2, P = .002), and medial lesions were more common in female patients (female vs male; 93.3% vs 81.8%, P = .036). The lesion sizes were larger in patients with a wider talar tilt angle ( P < .001), and patients with a medial OLT showed a wider talar tilt angle (12.0 ± 2.0 degrees vs 10.3 ± 2.2 degrees, P = .002). Conclusion: In this CLAI patient cohort, we found female patients to be at greater risk for OLTs than male patients. Furthermore, CLAI female patients with concomitant OLT had on average a larger lesion size, more frequent OLT medial position, and were associated with wider talar tilt angles, suggesting that females had more intrinsic ankle instability than males.

Modified Broström Procedure

The modified Brostrom procedure has been a proven procedure with excellent utility in the treatment of lateral ankle instability within limitation. Multiple variations of the original technique have been described in the literature to date. Included in these variations are differences in anchor placement, suture technique, or both. In this research study, we propose placing a bone screw anchor into the lateral shoulder of the talus rather than the typical placement at the lateral malleolus for anatomic reconstruction of the lateral ankle ligaments.

Lateral Ankle Ligaments

Ankle sprains are common injuries involving the lateral ankle ligaments and affect athletes of all levels. Most patients heal uneventfully, but those with symptoms persisting past 3 months should be evaluated for chronic ankle instability and its associated conditions as well as for the presence of varus malalignment. Chronic ankle instability is initially treated nonoperatively, with surgical management reserved for those who have failed to improve after 3 to 6 months of bracing and functional rehabilitation. Anatomic repair using a modification of the Broström procedure is the preferred technique for initial surgery. Anatomic reconstruction with tendon graft should be considered when repair is not possible, as it maintains physiological joint kinematics. Nonanatomic reconstructions are seldom indicated. Arthroscopic repair or reconstruction of the lateral ankle ligaments is a promising new technique with results similar to those of open surgery.

Objective: The aim of this study is to demonstrate an original technique in which a stable construct is made by fibular and calcaneal bone tunnels producing a figure of 8 with a Polyester implant as revision for failed primary ligament reconstruction. Methods: This is a retrospective study of 19 patients with persistent lateral ankle instability diagnosis after a primary ligament repair treated between 2011 and 2019. The surgical technique is described in detail in which stabilization of the lateral ankle is performed. 11 men and 8 women with a mean age of 30.94 years (15-53). Follow up was 29.05 months (6-109). Pre and postoperative AOFAS ankle score were used as well as an AVS and a satisfaction questionnaire. Results: There was a significant improvement in AOFAS score, 76.31 to 91.47 (<0.001). All the patients except one, stated to have a stable ankle and be Very satisfied (16) or satisfied (2) with the procedure. No infection was presented in any patient. Conclusion: This technique is a reliable alternative in patients in which primary ankle ligaments have failed and no autograft or allograft are wanted to be used. Level of Evidence V; Therapeutic Study; Expert Opinion.

Background: Osteochondral lesions (OCLs) and bony impingement are common secondary lesions of chronic lateral ankle instability (CLAI), but the risk factors that predict OCLs and bony impingement are unknown. Purpose: To analyze the risk factors for the development of OCLs and osteophytes in patients with CLAI. Study Design: Case-control study; Level of evidence, 3. Methods: Patients diagnosed with CLAI at our institution from June 2007 to May 2018 were enrolled. The assessed potential risk factors were age, sex, postinjury duration, body mass index, injury side, and ligament injury type (isolated anterior talofibular ligament [ATFL] injury, isolated calcaneofibular ligament [CFL] injury, or concomitant ATFL and CFL injuries). Univariate and multivariate logistic regression analyses were performed to evaluate the association between these factors and the presence of OCLs and osteophytes. Results: A total of 1169 patients with CLAI were included; 436 patients (37%) had OCLs and 334 (31%) had osteophytes. The presence of OCLs was significantly associated with the presence of osteophytes ( P < .001). Male sex and older age were significantly associated with the presence of OCLs in the medial and lateral talus. A postinjury duration of 5 years or longer was significantly associated with the presence of OCLs in the medial talus (odds ratio [OR], 1.532; 95% CI, 1.023-2.293; P = .038) but not in the lateral talus. ATFL and CFL injuries were both significantly associated with the presence of lateral OCLs. Risk factors for the presence of osteophytes were male sex, older age, postinjury duration 5 years or longer, and CFL injury. Patients with concomitant ATFL and CFL injuries were significantly more likely to have osteophytes than were patients with single-ligament injuries ( P = .018). Conclusion: Risk factors for OCLs and osteophytes were postinjury duration of 5 years or longer, older age, and male sex. ATFL injury was associated with the presence of lateral OCLs, whereas CFL injury was associated with the presence of lateral OCLs and osteophytes. Patients with these risk factors should be closely monitored and treated to reduce the incidence of ankle arthritis.

Purpose: this study was conducted to evaluate longterm results following treatment of chronic lateral ankle instability using the Broström-Gould technique in athletes. Methods: eighteen athletes involved in competitive sports at different levels, who suffered from chronic lateral ankle instability, underwent Broström-Gould ligamentoplasty between 2000 and 2005. The results of the surgery were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scale. Results: the results at 10-15 years of follow-up were excellent in 94.5% of these cases and good in the remaining 5.5%. An increase of 31.2 points in the AOFAS scale score was recorded at follow-up (with the score rising to 98.8, from 67.6 preoperatively). All the athletes returned to their respective sports at the same level as prior to the surgery. Imaging at longterm follow-up showed no signs of arthritic degeneration. Conclusions: the results of this study show that the Broström-Gould technique is an effective procedure for the treatment of chronic lateral ankle instability in the athlete, giving excellent long-term results. Level of evidence: therapeutic case series, level IV.

Background: Chronic lateral ankle instability is relatively common after ankle sprains. The modified Broström-Gould procedure (MBG) is the gold standard operative treatment but has a known failure rate of up to 10%, or even more in high-risk groups. Periosteal flap augmentation (PFA) has been proposed to strengthen the repair. This study aimed to compare the outcomes of MBG with and without PFA. Methods: A matched-pair study was performed based on prospectively collected registry data for all patients undergoing lateral ankle ligament reconstruction in a tertiary institution. Patients who underwent the MBG with PFA were matched in a 1:1 ratio with patients undergoing MBG alone, based on age, gender, and body mass index (BMI). Patients with generalized ligamentous laxity or obesity were excluded. Clinical outcome scores were compared preoperatively and 2 years postoperatively. A total of 48 patients were included in the study (24 in each group). The mean age was 24.1 years, mean BMI was 23.1, and all patients were male. The baseline demographics and clinical scores in both groups were similar. Results: At 2 years postoperatively, both groups demonstrated significantly improved AOFAS Ankle-Hindfoot scores ( P < .001), but there were no between-group differences in total AOFAS scores (PFA score 90, MBG score 88, P = .79). There were no recurrences of instability or revision surgeries. Conclusion: Routine PFA did not improve the outcomes of MBG for chronic lateral ankle instability in the absence of risk factors for failure. Further studies are warranted to determine if there is a long-term benefit for augmentation in this population. Level of Evidence: Level III, retrospective comparative study.

Category: Ankle, Sports Introduction/Purpose: Chronic lateral ankle instability (LAI) is a common cause of ankle pain. Surgical interventions have been shown to be highly effective in alleviating patient’s symptoms once conservative care has failed. Stress radiographs have not demonstrated a clear efficacy in diagnosing ankle instability. Currently, MRI is considered to be superior to stress radiographs in the available literature. Unfortunately, the literature comparing these methods is limited. The purpose of this study is to compare the results of an MRI and manual inversion stress radiographs, in order to assess the accuracy of each modality in assessing the lateral ankle ligament competence. We believe that stress radiographs may have more value in confirming chronic ankle instability than the more expensive MRI imaging. Methods: A retrospective chart review was performed between January 2016 - July 2018 for patients diagnosed with LAI. The review identified 318 cases, of which 57 met the study criteria of having both an AP manual inversion stress radiographs, assessed by the senior author, and MRI, interpreted by a musculoskeletal radiologist, occurring within 6 months of each other without an acute injury within 12 weeks of the first image. For the remaining 57 cases, the imaging was reviewed in the following manner. For the MRI studies, the report was read from the radiologist assessing the lateral ankle complex. A positive MRI was denoted as pathology being reported by the radiologist. For the manual inversion stress radiograph, measurements were made to assess the degree of talar tilt while being stressed. A positive stress radiograph was identified based on asymmetry of the ankle joint during the stress. Results: The average time between imaging studies was 7.2±7.4 weeks (range 0.5-24 weeks). Of the 57 cases that qualified for the study, 43 (75%) had a positive stress radiograph, and 21(37%) had a positive MRI. 24 cases (42%) demonstrated a positive stress radiograph with a negative MRI, while 2 cases (4%) demonstrated a negative stress radiograph with a positive MRI. In respect to talar tilt, those patients identified as having a positive stress radiograph also had a higher average talar tilt when compared to those who did not. The degree of talar tilt for each set of criteria is summarized in Table 1. Conclusion: Historically, lateral ankle instability has been a clinical diagnosis. When further imaging is needed, our data suggests stress radiographs may demonstrate a higher reliability than MRI when assessing the competence of the lateral ankle ligaments. Asymmetry in a joint during an inversion stress examination has been shown to be indicative of multi ligament involvement. Few studies have attempted to define a talar tilt consistent with instability and our data does not meet those numbers. However, with the addition of bundled care and rising health care costs, we believe this provides a potential alternative in confirming a diagnosis of ankle instability.
