Category: Ankle Introduction/Purpose: There has a been recent increase in the use of the arthroscopic approach to lateral ankle ligament repair for chronic lateral ankle instability. However, the clinical outcomes of this technique are still unclear. The purpose of this systematic review was to evaluate the current studies on arthroscopic lateral ankle ligament repair for chronic lateral ankle instability. Our hypothesis was that arthroscopic lateral ligament repair would result in excellent outcomes with a low complication rate. Methods: A systematic search of MEDLINE, EMBASE and Cochrane Library databases, based on the PRISMA guidelines, was performed during August 2017 by 2 independent reviewers. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and percentage of patients who returned to sport at previous level were also evaluated. Results: Twelve studies for a total of 421 ankles were included; 92% of studies were LOE III or IV and the QOE in all studies was of poor or fair quality. The weighted mean preoperative AOFAS score improved from 59.6 to 95.0 at a mean follow-up of 14.8 months in 8 studies. Five studies utilized Karlsson-Peterson scores with mean postoperative score of 88.5 at a mean follow-up of 21.2 months. Three comparative studies were reported. The comparative studies showed similar clinical outcomes between arthroscopic and open procedures. The overall complication rate was 13.4% in the included studies. . Only 2 studies reported patients returning to sport and demonstrated that 100% of patients returned to sport at pre-injury level. Conclusion: The current systematic review demonstrated that arthroscopic lateral ankle ligament repair yields favorable clinical outcomes in the short-term. However, there is no clinical evidence to support the advantages of the arthroscopic procedure over the open procedure, and there is no long-term data currently available for the arthroscopic procedure. There was a relatively high complication rate associated with the arthroscopic procedures, with a 13.4% complication rate, although recent comparative studies demonstrated similar complication rates for both open and arthroscopic techniques.

Category: Ankle, Arthroscopy, Sports Introduction/Purpose: Open modified Broström-Gould procedure is generally accepted as the gold-standard treatment for chronic lateral ankle instability. Recently an arthroscopic lateral ankle ligament repair technique has become increasingly popular in an effort to reduce post-operative pain and facilitate early recovery. The purpose of the current systematic review was to evaluate the current evidence on arthroscopic lateral ankle ligament repair techniques and to compare the clinical outcomes of arthroscopic and open techniques for chronic lateral ankle instability with meta-analysis. Methods: A systematic search of MEDLINE and EMBASE databases was performed during August 2017. Included studies were evaluated with regard to level of evidence (LOE) and quality of evidence (QOE) using the Coleman Methodology Score. Variable reporting outcome data, clinical outcomes, and percentage of patients who returned to sport at previous level were also evaluated. Comparative studies were compared using RevMan version 5.3, and a p-value of < 0.05 was considered statistically significant. Results: Twelve studies for a total of 421 ankles were included; 92% of studies were LOE III or IV and the QOE in all studies was of poor or fair quality. There were three comparative studies of open and arthroscopic repair procedures, with two Level III studies and one Level I study. There was a significant difference in favor of arthroscopic repair at final follow-up for the Karlsson- Peterson score (MD; 2.59, 95%CI, -0.19 to 2.36, I2=0%, p=0.10) and the AOFAS score (MD; 1.50, 95%CI, 0.41 to 2.59, I2=0%, p=0.007) in the comparative studies. The overall complication rate was 13.4% in the included studies but in the comparative studies there was no statistically significant difference between open and arthroscopic repair (12.1% vs 11.4%, p=0.90). Conclusion: The current systematic review demonstrated that arthroscopic lateral ankle ligament repair may yield favorable clinical outcomes and may be superior to open procedure in the short-term, but there is no clinical evidence to support the advantages of the arthroscopic procedure over the open procedure in the mid- long-term follow-up. There was a relatively high complication rate associated with the arthroscopic procedures, with a 13.4% complication rate, although recent comparative studies demonstrated similar complication rates.

Lateral Ankle Ligament

Chronic lateral ankle instability may be present in as many as 10% to 30% of people suffering from acute lateral ankle ligament injuries. Ankle instability has been referred to as either functional instability or mechanical instability. Management options consist of either nonoperative or operative treatment, with the majority of the literature emphasizing operative management for chronic instability. Long-term studies assessing the different types of available operative repairs have now been published. This review article discusses chronic lateral ankle ligament instability from a functional, anatomical point of view. The indications for treatment, nonoperative and operative treatment, as well as the biomechanical information available regarding these methods of treatment are considered. The major emphasis of this review is discussion and analysis of the many different surgical treatment options. Following this review, we presently recommend anatomical repair to the bone of both the anterior talofibular ligament and the calcaneofibular ligament, together with imbrication of the ligaments. In patients with hypermobility, long-standing instability, or arthritis, reconstruction using the Chrisman-Snook technique is recommended.

Ankle Ligament Injury

Category: Ankle; Other Introduction/Purpose: Chronic lateral ankle instability (CLAI) that is developed after multiple lateral ankle ligament injury lead to ankle osteoarthritis. Although isolated deltoid ligament injury is rare compared to lateral ankle ligament injury, deltoid ligament tear, especially deep posterior tibiotalar ligament (PTT) can be observed arthroscopically in CLAI patients. Unphysiological loading of the ankle joint with CLAI might cause degradation of the deltoid ligament. This study aimed to investigate image findings of the deltoid ligament using computed tomography (CT) value for quantitative analysis of degenerative ligament changes in CLAI patients. Methods: Among the enrolled patients who underwent ankle magnetic resonance imaging (MRI) and CT scans of the ankle, this retrospective analysis included 24 ankles without ankle osteoarthritis, osteochondral lesion of the talus (OLT), flatfoot and ankle fractures (14 males and 10 females; mean age, 42.8 years) as a control group, and 14 CLAI ankles without OLT (7 males and 7 females; mean age, 31.1 years) as CLAI group. The CT scans were performed using a 64-slice multidetector row CT. Deep PTT was detected on coronal T2-weighted MR images. Both the coronal MR and CT images were matched for analysis, then average CT values were measured using the region of interest that was applied to the detected area of deep PTT on the CT images. Spearman’s correlation coefficient was used to evaluate the correlation between age and CT value in the control group. Results: The strong negative correlation was identified between age and CT value in the control group (Spearman ρ= -0.88; p < 0.001). The CT value of the deep PTT are degraded with aging. Mean CT value of deep PTT in participants under 60 years old were 79.9 HU (95% CI, 75.1-84.8) in the control group (18 ankles), and 66.5 HU (95% CI, 58.6-74.5) in the CLAI group (14 ankles) (Welch’s t test; p = 0.005). Conclusion: MRI techniques and protocols recently have been developed, however, some limitations remain such as a quantitative evaluation of the ligament. Our findings suggest that the CLAI can lead to degradation of the deltoid ligament via an overloading of medial ankle structures. Additionally, CT values should be useful for quantitatively evaluating ligament status including degenerative changes.

Associated Conditions

Background: Ankle sprains have a high incidence of associated injuries and conditions that may be unrecognized at the initial time of injury. Failure to treat these conditions at the index surgery may compromise outcomes and delay recovery. The purpose of this study was to determine the type and frequency of associated injuries and conditions in military patients with chronic lateral ankle instability. Methods: Between 1996 and 2002, 160 patients had 180 modified Broström-Gould lateral ankle ligament reconstructions for chronic ankle instability. A retrospective review of the clinical history, physical examination, radiographs, and intraoperative findings was conducted. Results: The overall incidence of associated extra-articular conditions and injuries found in this study was 64%; 115 conditions were identified in 180 ankles. Peroneal tendon injuries occurred with the highest frequency (28%), followed by os trigonum lesions (13%), lateral gutter ossicles (10%), hindfoot varus alignment (8%), anterior tibial spurs (3%), and tarsal coalitions (2%). Twenty revision lateral ankle ligament reconstructions were required for either persistent pain or recurrent instability. The most common associated conditions were undiagnosed hindfoot varus alignment abnormalities (28%) followed by untreated peroneal injuries (25%). Conclusions: This study confirms the frequency of conditions associated with lateral ankle instability and emphasizes several conditions that have received little attention in the literature. Identifying these associated conditions before surgery enables the surgeon to treat all conditions at one operation, returning the patient to full activity sooner. Guidelines are presented to assist clinicians in screening patients for these associated conditions.
