  • Acute ankle sprain is the most common injury in the lower extremities, and approximately 10% to 40% of acute lateral ankle ligament injury causes chronic pain or instability. For chronic symptoms lasting after an acute sprain, the possibility of joint damage, such as bony structures, ligaments, cartilage, and nerves around the ankle joint, should be considered. Patients with chronic lateral ankle instability usually complain of repeated sprains or giving way sensations. There has been steady progress in the treatment options until recently, however new treatments are still being attempted. This paper describes the causes, diagnosis, and recent trends in the conservative and operative treatment of chronic lateral ankle instability.

  • Chronic lateral ankle instability occurs in 10% to 20% of individuals after acute ankle sprain. The management of chronic lateral ankle instability is traditionally conservative treatment in the acute phase. On the other hand, surgical intervention is considered if conservative treatment fails and the symptoms are ongoing. This review focuses on the surgical approaches to treatment of chronic lateral ankle instability, including $Brostr{\ddot{o}}m$ surgical techniques, with a review of the traditional procedure and newer techniques.

  • A modified $Brostr{\ddot{o}}m$ procedure has been widely accepted as a treatment of choice for patients with chronic lateral ankle instability. The procedure is highly reliable and provides successful outcomes in approximately 90% of cases. Severe degree of instability, absence or poor quality of the ligamentous remnant, obesity, and generalized joint hypermobility have been regarded as poor prognostic factors related to the modified $Brostr{\ddot{o}}m$ procedure. However, these perceptions are based on a low level of evidence studies or expert opinions. Therefore, the aim of this article was to search for evidences regarding the poor prognostic factors of the modified $Brostr{\ddot{o}}m$ procedure.

  • Purpose: Anterior drawer and varus stress radiographs are commonly to diagnose chronic lateral ankle instability. We compared the preoperative stress radiographs with the intraoperative radiographs under anesthesia to determine the accuracy and efficacy of stress radiographs in an outpatient clinical environment. Materials and Methods: Data was collected from patients who underwent a modified $Brostr{\ddot{o}}m$ operation for painful chronic unilateral lateral ankle instability between January 2014 and June 2016. Subjects were divided into three groups-complete tear, partial tear, and instability without rupture-according to the status of preoperative MRI findings of the anterior talofibular ligament. The anterior drawer and varus stress radiographs were taken preoperatively and intraoperatively under anesthesia. Results: Ninety-six patients, with a mean age of 29.63 years, were enrolled. There were 39, 46, and 11 patients in the complete tear, partial tear, and instability without rupture groups, respectively. On the anterior drawer and varus stress radiographs of the affected limb, talar anterior translation and varus tilting were significantly increased by 2.56 mm and $2.0^{\circ}$. The gaps between the unaffected limbs were also increased by 2.47 mm and $1.32^{\circ}$ after anesthesia. Although the stress radiographs were taken under anesthesia, the results were often smaller than the diagnostic value. Conclusion: Stress radiographs for painful chronic lateral ankle instability taken at the outpatient clinic might be inaccurate for diagnosis.

  • Purpose: This study investigated the short-term effectiveness of extracorporeal shock wave therapy (ESWT) on pain, the ankle instability, the ankle function, dorsiflexion range of motion (ROM), and dynamic balance in patients with chronic ankle instability (CAI). Methods: Eighteen participants were divided into an experimental (n=9) and control group (n=9). The ESWT in the experimental group was applied to the lateral collateral ligament in combination with the tibialis anterior whereas the ESWT was applied to the lateral collateral ligament of the ankle alone in the control group. Pain, the ankle instability, the ankle function, dorsiflexion ROM, and dynamic balance were measured using the Visual analog scale, Cumberland ankle instability tool, American Orthopedic Foot and Ankle Society ankle-hindfoot score, weight-bearing lunge, and Y-balance test, before and after ESWT intervention. Results: Significant interactions (group × time) and time effects were observed in the dorsiflexion ROM and dynamic balance. Bonferroni's post-hoc analysis showed that the experimental group revealed a more significant change in dorsiflexion ROM and dynamic balance than the control group. There was a significant time effect in the pain, the ankle instability, and the ankle function, but no significant interaction (group × time) was observed. Conclusion: The ESWT could improve the pain, ankle instability, ankle function, dorsiflexion ROM, and dynamic balance in patients with CAI. Furthermore, the ESWT combined with lateral ankle ligaments and tibialis anterior more improves the dorsiflexion ROM and dynamic balance.

  • Purpose: Several methods of anatomical reconstruction for chronic lateral ankle instability has been reported to avoid the problems of nonanatomical reconstruction. Precise reconstruction of the normal anatomy is essential to the restoration of normal joint mechanics and stability. The problem with anatomical reconstruction is that it is very difficult to reconstruct the normal anatomic course of the ligaments. We thought making one tunnel at the fibular attachment of anterior talofibular ligament and calcaneofibular ligament was more anatomical than making separate tunnels for each ligaments because the two ligaments are contiguous. In this article, the basis of anatomical reconstruction of the lateral ankle ligaments was reviewed and a technique of reconstruction using semitendinosus was introduced.

  • The modified Brostrom procedure is first considered for the treatment of chronic ankle instability (CAI). Recently, ankle arthroscopy is also recommended for the treatment of concomitant intra-articular lesions during the open repair of the lateral ligaments. We arthroscopically repaired the anterior talofibular ligament with a use of bio suture anchor for CAI as well as performing the multiple drilling procedure for combined osteochondral lesion of talus. We report the cases with a review of the literature.

  • Purpose: To find out the priority of which procedure has had a better outcome both clinically and radiographically between the two groups, one is treated by primary repair and the other by modified Brostr$\ddot{o}$m's procedure, by comparing the postoperative ankle joint stability and the patient's degree of satisfaction. Material and methods: 16 cases were taken into consideration whose number of severed ligaments were at least two or more of the lateral collateral ligaments of the ankle, and also were confirmed intraoperatively. Among them, 8 cases were treated with primary repair and the other 8 cases were treated with primary repair and the other 8 cases by modified Brostr$\ddot{o}$m's procedure. Results: There was no distinguishable difference for the patient's degree of satisfaction between the two procedures above mentioned. In 3 cases treated with primary repair, functional instability was observed. In case of postoperative ankle joint stability, 7 of 8 cases treated by modified Brostr$\ddot{o}$m's procedure has revealed increased joint stability. And 3 of 8 cases which were treated by primary repair have showed postoperative residual instability. Conclusion: Actually, the severed ligament can not maintain its normal strength though several months has elapsed, and possible residual instability could be remained. Therefore, it can be expected that modified Brostr$\ddot{o}$m's procedure also would be a .good method in obtaining suitable ankle joint stability as well as subtalar joint stability because of its reinforcement using extensor retinaculum.

  • Many surgical procedures have been described for the treatment of chronic lateral instability of the ankle. Tenodesis procedures using peroneus brevis tendon is traditionally common among them. Recently, the modified Brostrom anatomic procedure, that is, tightening the stretched out lateral ligaments to restore their norma] anatomy without the use of supplemental tissues and then suturing the lateral portion of the extensor retinaculum to the distal fibula over the ligament repair. has been gaining in popularity. We have reviewed 6 of 10 consecutive cases at an average of 17 months after modified Brostrom procedure. An excellent or good result was achieved in 5 cases, all of which had improved mechanical stability as measured radiographically. One case that had an unsatisfactory result was in patient who had had a previous Evans' operation. So, we believed that the modified Brostrom procedure is an excellent treating method for chronic lateral instability of the ankle.
