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.

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.

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.

Varus Stress

Category: Ankle Introduction/Purpose: Insufficient bony coverage surrounding the talus could cause considerable mechanical ankle instability, whereas excessive bony coverage could cause bone contusion at the time of injury and subsequent osteochondral lesions of the talus (OLT). This study aimed to investigate the relationship between radiographic lateral ankle instability and OLT in patients that sustained ankle inversion injuries. Methods: One-hundred-ninety-five patients (113 men and 83 women; mean age, 38.7 years; standard deviation, 8.8 years) with a history of ankle inversion injuries were included. All patients underwent ankle magnetic resonance imaging (MRI) and stress X-ray (varus stress and anterior drawer) examination. The tibiotalar tilt angle on varus stress X-ray, anterior translation of the talus on anterior-drawer lateral X-rays, bimalleolar tilt angle, and fibular position were radiographically determined. The anatomical grade of the lateral ankle ligament injury and the presence of OLTs were determined from MRI findings. Results: A greater lateral ankle ligament grade tends to increase the tibiotalar tilt angle (p=0.074), significantly affecting the anterior translation of the talus (p=0.036). The presence of radiographic lateral ankle instability (tibiotalar tilt angle =10°) showed opposite associations with the presence of OLT in the chi-square test (p=0.003). OLT was a negative significant factor (p=0.011) affecting the tibiotalar tilt angle in the multiple regression analysis (Table 1) and was negatively affected by the tibiotalar tilt angle (p=0.016) in the binary logistic regression analysis. Conclusion: This study showed an opposite association between lateral ankle instability and the development of OLT following ankle inversion injury. The role of bony predisposition in the development of sports injuries in the ankle should be considered and investigated further.

Anterolateral Impingement

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.
