Endoscopic anatomic ligament reconstruction is a reliable option to treat chronic lateral ankle instability

Sixty-one patients underwent a primary ankle lateral ligament reconstruction for chronic instability between 1989 and 1996. In addition to the ligament reconstruction, all patients had evaluation of the peroneal retinaculum, peroneal tendon inspection by routine opening of the tendon sheath, and ankle joint inspection by arthrotomy. A retrospective review of the clinical history, physical exam, MRI examination, and intraoperative findings was conducted on these 61 patients. The purpose was to determine the type and frequency of associated injuries found at surgery and during the preoperative evaluation. At surgery no patients were found to have isolated lateral ligament injury. Fifteen different associated injuries were noted. The injuries found most often by direct inspection included: peroneal tenosynovitis, 47/61 patients (77%); anterolateral impingement lesion, 41/61 (67%); attenuated peroneal retinaculum, 33/61 (54%); and ankle synovitis, 30/61 (49%). Other less common but significant associated injuries included: intra-articular loose body, 16/61 (26%); peroneus brevis tear, 15/61 (25%); talus osteochondral lesion, 14/61 (23%); medial ankle tendon tenosynovitis, 3/61 (5%). The findings of this study indicate there is a high frequency of associated injuries in patients with chronic lateral ankle instability. Peroneal tendon and retinacular pathology, as well as anterolateral impingement lesions, occur most often. A high index of suspicion for possible associated injuries may result in more consistent outcomes with nonoperative and operative treatment of patients with chronic lateral ankle instability.

Lateral Ankle Instability

Background There has been no attempt to correlate the type and number of intra-articular lesions with the results of ligament reconstruction for chronic lateral ankle instability. Hypothesis Certain intra-articular lesions affect the clinical outcome of ligament reconstruction. Study Design Case series; Level of evidence, 4. Methods Sixty-five ankles from 64 patients underwent a modified Broström operation for chronic lateral ankle instability with a mean follow-up of 28.7 months (range, 12–67). The results were assessed according to the Karlsson-Peterson Ankle Score. The type of intra-articular lesions and the association of clinical outcome were investigated using Pearson's correlation coefficient and multivariate logistic regression analysis. Results The average Karlsson-Peterson Ankle Score was improved from 53 ± 14.63 preoperatively to 85.21 ±11.97 at final follow-up ( P < .001). Five different intra-articular lesions were described in 63 ankles (96.9%), and the ankle score negatively correlated with the number of lesions ( r = −.604; P < .001). Multivariate logistic regression showed that syndesmosis widening (odds ratio, 11.1; 95% confidence interval: 2.2–55.4; P = .003), osteochondral lesions of the talus (odds ratio, 8.5; 95% confidence interval: 1.7–42.3; P = .008), and ossicles (odds ratio, 4.5; 95% confidence interval: 1.0–20.2; P = .046) are significant predictors of unsatisfactory results after ligament reconstruction. Conclusion Arthroscopic diagnosis and treatment of intra-articular lesions associated with chronic lateral ankle instability is a safe and effective method. The presence of any combination of associated intra-articular lesions can result in a poor outcome.

Abstract Introduction The most common ankle injury is a sprain. Surgical management is only indicated when nonoperative treatment fails. Modified Broström-Gould (MBG) is the gold standard surgical technique. MBG technique may be augmented with an internal brace. This study aims to compare the clinical outcomes of MBG with and without internal brace for the treatment of chronic lateral ankle instability using validated patient recorded outcome measures. Method Retrospective analysis of patients that underwent lateral ankle ligament reconstruction between January 2012 and June 2019 were reviewed at and asked to complete the Manchester oxford foot and ankle questionnaire (MOXFQ). 29 patients (30 ankles) underwent lateral ligament reconstruction between these dates and completed the questionnaire, 20 patients (21 ankles) without internal brace and 9 patients with internal brace. Results The group with internal brace displayed significantly better results in the MOXFQ summary index score (20.49 ± 13.15 vs 43.53 ± 34.72, P = 0.014) and standing/walking subscale (15.48 ± 13.00 vs 45.92 ± 36.60, P = 0.023) compared to group without internal brace. There was no significant difference between Pain and Social interactions subscales. Conclusions Our results show that the addition of an internal brace to the MBG procedure for the management of chronic lateral ankle instability improves clinical outcomes.

Category: Ankle; Arthroscopy; Sports Introduction/Purpose: This study evaluates the effects on functional outcomes of with or without calcaneofibular ligament reconstruction when reconstructing the ATFL for chronic lateral ankle instability Methods: This retrospective cohort study included 48 chronic lateral ankle instability patients with later ligament reconstruction that underwent either with or without a calcaneofibular ligament reconstruction using an ipsilateral free semitendinosus tendon autograft from June 2014 to October 2017. The Visual Analogue Scale score, the American Orthopaedic Foot & Ankle Society score, Karlsson Ankle Functional Score and Anterior Talar Translation in both groups were compared. Results: All patients were followed up for at a mean of 30 months, Visual Analogue Scale score, the American Orthopaedic Foot & Ankle Society score, Karlsson Ankle Functional Score and Anterior Talar Translation between two the groups were not statistically significant different. Conclusion: There are no differences at 2.5 years in postoperative ankle function and stability when an ipsilateral free semitendinosus tendon autograft is used to manage CLAI with anterior talofibular ligament reconstruction with and without reconstructing the calcaneofibular ligament.

Lateral Ankle Instability

Background: Ankle stress radiographs are important tools for evaluating chronic lateral ankle instability. The consistency of a patient’s ankle condition as it affects the reliability of ankle stress radiographs has never been evaluated. Purpose: To investigate the consistency and reliability of ankle stress radiographs in patients with chronic lateral ankle instability without an ankle injury during the study period. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Included were patients with chronic lateral ankle instability who underwent 2 repeated ankle stress radiographs between January 2014 and July 2019; those with an ankle injury during the study period were excluded. The tibiotalar tilt angle on varus stress radiographs and anterior translation of the talus on anterior drawer stress radiographs were measured at initial presentation and final follow-up examination. Interobserver reliability and consistency of ankle stress radiographs were analyzed using the intraclass correlation coefficient (ICC). Results: A total of 45 patients (mean ± standard deviation age, 36.4 ± 13.4 years; 18 men and 27 women; follow-up duration, 9.1 ± 3.2 months) were included. The mean ± standard deviation tibiotalar tilt angle and anterior talar translation at initial presentation were 10.8° ± 5.2° and 6.9 ± 2.7 mm, respectively. The interobserver reliabilities of the tibiotalar tilt angle and anterior talar translation were excellent (ICC = 0.926 [95% CI, 0.874-0.959] and 0.911 [95% CI, 0.766-0.961], respectively). The consistency between the initial and final radiographs was good for tibiotalar tilt angle (ICC = 0.763 [95% CI, 0.607-0.862]) and poor for anterior talar translation (ICC = 0.456 [95% CI, 0.187-0.660]). Conclusion: Although the interobserver reliability of the radiographic measurements was excellent, the consistency of the ankle stress radiographs was not as acceptable. Surgeons need to be cautious when deciding whether to operate on a patient with chronic lateral ankle instability based on a single ankle stress radiograph.

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. Level of Evidence: Level IV, retrospective case series.
