Chronic ankle instability can result from untreated or badly managed acute lateral ankle ligament injuries. Conservative management is the modality of choice for acute lateral ankle ligament injuries, and operative treatment is reserved for special cases. Failure after strict rehabilitation may be an indication for surgery. Several operative options are available, including anatomic repair, anatomic reconstruction, and tenodesis procedures. Anatomic repair can be performed when the quality of the damaged ligaments permits. Anatomic reconstruction with an autograft or allograft should be considered when the torn ligaments are not adequate. Ankle arthroscopy is a useful adjunct to ligamentous procedures, performed at the time of repair to identify and treat intra-articular conditions that may be associated with chronic ankle instability. Tenodesis techniques are not recommended because of their suboptimal long-term results related to the modification of ankle and hindfoot biomechanics. Level of Evidence: Level V, expert opinion.

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 Reconstruction

Background: Anatomic lateral ankle ligament reconstruction has been proposed for patients with chronic ankle instability. A reliable approach is a reconstruction technique using an allograft and 2 fibular tunnels. A recently introduced approach that entails 1–fibular tunnel reconstruction might reduce the risk of intraoperative complications and ultimately improve patient outcome. Hypothesis: We hypothesized that both reconstruction techniques show similar ankle stability (joint laxity and stiffness) and are similar to the intact joint condition. Study Design: Controlled laboratory study. Methods: A total of 10 Thiel-conserved cadaveric ankles were divided into 2 groups and tested in 3 stages—intact, transected, and reconstructed lateral ankle ligaments—using either the 1– or the 2–fibular tunnel technique. To quantify stability in each stage, anterior drawer and talar tilt tests were performed in 0°, 10°, and 20° of plantarflexion (anterior drawer test) or dorsiflexion (talar tilt test). Bone displacements were measured using motion capture, from which laxity and stiffness were calculated together with applied forces. Finally, reconstructed ligaments were tested to failure in neutral position with a maximal applicable torque in inversion. A mixed linear model was used to describe and compare the outcomes. Results: When ankle stability of intact and reconstructed ligaments was compared, no significant difference was found between reconstruction techniques for any flexion angle. Also, no significant difference was found when the maximal applicable torque of the 1-tunnel technique (9.1 ± 4.4 N·m) was compared with the 2-tunnel technique (8.9 ± 4.8 N·m). Conclusion: Lateral ankle ligament reconstruction with an allograft using 1 fibular tunnel demonstrated similar biomechanical stability to the 2-tunnel approach. Clinical Relevance: Demonstrating similar stability in a cadaveric study and given the potential to reduce intraoperative complications, the 1–fibular tunnel approach should be considered a viable option for the surgical therapy of chronic ankle instability. Clinical randomized prospective trials are needed to determine the clinical outcome of the 1-tunnel approach.

Objectives: Lateral ankle ligament stabilization may be performed with concomitant arthroscopy. Arthroscopy has been shown to aid in the diagnosis of intra-articular defects that often accompany lateral ankle ligament injuries. This study compares the differences in cost, complications, newly diagnosed intra-articular defects, and reoperations among patients with ankle sprain/chronic instability who underwent lateral ankle ligament repair/reconstruction with or without concomitant arthroscopic procedures. Methods: Data was collected from the PearlDiver Technologies Humana dataset using CPT and ICD9/10 codes. Patients included in this study (n=2,188) had records of ankle sprain or ankle instability prior to or on the same day as one of two procedures: lateral ankle ligament repair (n=1,141) or lateral ankle ligament reconstruction (n=1,063). This population was subdivided by whether patients had records of arthroscopic procedure(s) on the same day as the ligament surgery. This yielded four groups: repair with arthroscopy (n=219), repair without arthroscopy (n=922), reconstruction with arthroscopy (n=325), reconstruction without arthroscopy (n=738). Cost, complications, newly diagnosed intra-articular defects, and reoperations were assessed. Results: Average cost per patient was higher for both arthroscopy groups: repair with arthroscopy ($6,207.78) versus repair without arthroscopy ($3,677.11; p < 0.0001); reconstruction with arthroscopy ($5,758.21) versus reconstruction without arthroscopy ($4,601.13; p = 0.0039). There was a significantly higher proportion of patients with complications in the reconstruction without arthroscopy group than in the reconstruction with arthroscopy group (7.59%, 4.31%; p = 0.0431), but the difference between repair groups was insignificant (p = 0.0626). The proportion of patients with newly diagnosed intra-articular defects was significantly higher in both arthroscopy groups: repair with arthroscopy (53.0%) versus repair without arthroscopy (35.6%; p < 0.0001); reconstruction with arthroscopy (56.0%) versus reconstruction without arthroscopy (39.8%; p < 0.0001). There was a significantly higher proportion of patients who underwent reoperation for intra-articular defects in the combined (repair plus reconstruction) arthroscopy group (7.18%) than in the combined non-arthroscopy groups (4.91%; p = 0.049). Most importantly, the average time until reoperation for intra-articular defects was significantly shorter in the combined arthroscopy group (271.923 days) than in the combined non-arthroscopy group (411.473 days; p = 0.024). Conclusion: Concomitant arthroscopy with lateral ankle ligament surgery is more expensive but does not appear to increase the overall complication rate and may allow surgeons to diagnose and treat more intra-articular pathology. Among patients requiring reoperation for intra-articular defects, the average time to reoperation was nearly 5 months shorter for patients receiving arthroscopy than for patients who did not receive arthroscopy.

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.
