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.

Category: Sports Introduction/Purpose: The arthroscopic modified Broström operation (MBO) has been developed and frequently used to treat chronic lateral ankle instability (CLAI). Clinical outcome of arthroscopic MBO was reported as good or excellent. But there were no report about comparison of clinical outcomes between patients with generalized ligamentous laxity (laxity) and without generalized ligamentous laxity (no laxity). The purpose of this study is to compare the clinical outcomes of the group with generalized ligamentous laxity and without generalized ligamentous laxity in chronic lateral ankle instability. Methods: From January 2013 to November 2015, Arthroscopic MBO was performed in 99 patients for CLAI. We retrospectively analyzed 99 consecutive patients were included in terms of inclusion criteria. All patients had giving way, persistent pain and an inability to resume one’s preinjury activity level for more than 6 months. Patients were divided into 2 groups: laxity group (24 ankles) and no laxity group (75 ankles). Evaluation was performed preoperatively and at a final follow-up a minimum of 12 months postoperatively using the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot ankle score, pain Visual Analogue Scale (VAS)(0~100), and talar tilt angle. Results: In terms of radiological outcomes, the preoperatively talar tilt angle was greater in patients in laxity group than in no laxity group (p < .001). The last follow-up talar tilt angle was the same between in patients in laxity group and in no laxity group (p=0.413). But preoperative-last follow up difference was found between two groups (p=0.03). The variation from preoperative to last follow up talar tilt angle showed significant greater value in laxity group (-6.9 ± 5.2) than in no laxity group (-4.2 ± 4.2)(p=0.03). In terms of clinical outcome, last follow up AOFAS and VAS in all groups were improved than preoperative scores (27.5 ± 23.7, 24.1 ± 18.4, respectively). But preoperative-last follow up differences were not found between two groups (P=0.52). Conclusion: In terms of radiologic outcomes, there was difference outcome variation between two groups, in terms of clinical outcomes, there were no difference outcome variations between two groups. All groups achieved successful clinical and radiological last follow up outcomes even though there was difference outcome variation in talar tilt. Arthroscopic MBO should be considered as a reasonable method in patients who have chronic lateral ankle instability regardless of generalized ligamentous laxity.

Category: Sports Introduction/Purpose: Os Subfibulare(OSF) is an accessory ossicle that lies at the tip of the lateral malleolus of the ankle. Patients with chronic lateral ankle instability (CLAI) have a high incidence of OSF, and there relationship implies that there is a correlation between OSF and CLAI. The all-inside arthroscopic Modified Broström Operation (MBO) has been developed for the treatment of chronic lateral ankle instability (CLAI) and the outcome was reported as good or excellent. But there were no report about comparison of the outcome between OSF and non-OSF patients with chronic lateral ankle instability treated by all-inside arthroscopic MBO. The purpose of this study was to evaluate the clinical and radiologic outcomes of the arthroscopic MBO procedure for CLAI with or without OSF. Methods: From January 2013 to september 2016, arthroscopic MBO was performed on 133 patients with CLAI. Of these, 126 ankles were evaluated for this study. Patients were divided into two groups: the OSF group (26 patients), without OSF group (100 patients). Evaluation tools included the American Orthopedic Foot and Ankle Society (AOFAS) hindfoot ankle score and pain Visual Analogue Scale (VAS) at preoperatively, 6 and 12 months postoperatively for clinical outcomes. And we also evaluated the talar tilt angle in the varus stress radiograph at preoperatively, 6 and 12 months postoperatively for radiologic outcomes. Results: There were no difference in age, sex, preoperative AOFAS hindfoot ankle scores and VAS scores and talar tilt angle between the two groups preoperatively(P >.05). And there also were no difference at the final follow-up (P >.05).The final follow-up AOFAS hindfoot ankle score and Vas in both group showed improvement compared with preoperaive values. Conclusion: There were no difference in both clinical and radiologic outcomes between OSF group and non-OSF group at a minimum 12 months follow-up. We achieved similar successful outcomes in both groups using All-inside arthroscopic MBO. Arthroscopic MBO should be considered as a reasonable alternative method in patients who have chronic lateral ankle instability regardless of the presence of OSF.

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.

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.

Lateral Ankle Instability

Background: The anterior talofibular ligament and the calcaneofibular ligament are 2 of the most frequently injured structures in sports, being damaged in 30% to 45% of all sports injuries. Most reconstructive procedures are successful but can deteriorate with time and can lead to low-grade radiographic degeneration. Methods: We operated on 26 consecutive patients from 2001 to 2008 who had failed previous surgical procedures for the lateral ligamentous complex of the ankle, with an average of 104 (range, 75-140) months. Results: The overall functional rating was excellent in 14 ankles, good in 10, fair in 1, and poor in 1. Twenty-four patients (92.3%) were satisfied with the procedure and 15 (57.7%) were able to return to their preinjury level of activity. Local complications were detected in 2 patients who presented with skin necrosis; 1 patient developed severe reflex sympathetic dystrophy. Conclusion: Revision surgery for the management of failure after surgical treatment of chronic lateral ankle instability is under debate, and the literature is devoid of clinical studies with long-term follow-up. The technique described offers a high rate of long-term excellent and good results, with a low rate of complications and a good rate of return to preinjury level. Level of Evidence: Level IV, retrospective case series.

Category: Ankle, Trauma Introduction/Purpose: The current clinical standard for the surgical treatment of lateral ankle instability remains the modified Broström procedure. Almost surgeons are using non-absorbable suture material because of their strength & permanent. But this has several complications such as irritation, surface tenderness, etc. So we compare the clinical result between nonabsorbable and absorbable suture material. Methods: All patients who underwent the modified Broström operation of the anterior talofibular ligament and/or the calcaneofibular ligament by a single surgeon between July 2011 and May 2015 were included in this study. A total of 96 patients were included in this study: 63 men and 33 women (mean age, 33.16 years; range, 14-72 years). Non-absorbable suture(2-0 Fiberwire®, Arthrex, Naples, FL) patient were 50 (33 men, 17 women) and absorbable suture(0-Vicryl®, Ethicon, Sommerville, NJ) patient were 46(30 men, 16 women). Mean follow-up duration was 2.5 years (range, 1.0-4.7 years). Patients completed a subjective questionnaire. Outcomes measures included the Foot and Ankle Disability Index (FADI), American Orthopaedic Foot and Ankle Society (AOFAS) and Reoperation cases by the recurred lateral ankle instability. All data were collected prospectively and reviewed retrospectively. Results: In non-absorbable suture group, The mean talar tilt angle in preoperative talar tilt test was 14.4 and in absorbable suture group, 13.7, respectively. The mean talar tilt angle in postoperative talar tilt test was 5.3 and in absorbable suture group, 6.1, respectively. There were no significant differences between non-absorbable suture method and absorbable suture method with talar tilt angle in varus stress x-ray (P > .05). There was no significant difference in FADI (87 vs 91; P = .553), AOFAS (83 vs 87; P = .372) score between non-absorable suture method group and the absorbable suture method group. During follow up, Except of 2 patients, they were no clinical symptom. Each one patient in non-absorbable and absorbable suture group underwent revision lateral ligament surgery. Conclusion: As compared with non-absorbable suture in open modified Broström procedure, absorbable suture method produced similarly favorable outcomes.

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.

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.

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.
