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.

Background and objective: Numerous tape applications have been used in patients with chronic ankle instability (CAI). However, the effect of prophylactic ankle taping on lower-extremity kinematics is still not well understood. This study aimed to investigate the effects of traditional taping, fibular repositioning taping, and kinesiology taping on the peak angles of the lower extremities in patients with CAI. Materials and Methods: A total of 14 men (age, 24.07 ± 4.46 years; height, 175.06 ± 5.10 cm; weight, 82.24 ± 10.38 kg (mean ± standard deviation)) with CAI identified using screening questionnaires (Cumberland Ankle Instability Tool, 17.64 ± 4.14; Foot and Ankle Ability Measure (FAAM) Activity of Daily Living, 86.69 ± 6.71; and FAAM Sports Subscale, 75.45 ± 6.70) participated. The peak angles of the hip, knee, and ankle joints during a stop-jump task, with and without tape application, were collected using a three-dimensional motion system. Results: The following peak angles were measured: hip flexion, hip adduction (ADD), hip internal rotation (IR), knee flexion, knee abduction (ABD), knee IR, ankle dorsiflexion, ankle inversion, and ankle ADD. No significant differences were observed in the peak angle of each joint across conditions (hip flexion, F(3,39) = 0.85, p = 0.47; hip ADD, F(1.729,22.478) = 1.90, p = 0.18; hip IR, F(1.632,21.220) = 0.67, p = 0.49; knee flexion, F(3,39) = 1.24, p = 0.15; knee ABD, F(1.691,21.982) = 1.24, p = 0.30; knee IR, F(1.830,23.794) = 0.44, p = 0.63; ankle dorsiflexion, F(3,39) = 0.66, p = 0.58; ankle inversion, F(1.385,18.007) = 0.85, p = 0.40; ankle ADD, F(1.865,24.249) = 2.23, p = 0.13). Conclusion: The application of different taping techniques did not significantly change the peak joint angles of the lower extremities during a stop-jump task. These results contradict those of previous studies, suggesting that ankle taping restricts joint range of motion.

Short And Long Term

Treatment of chronic ankle instability remains a challenge for orthopedic surgeon. Surgical procedures for this disorder include anatomic direct repair, anatomic reconstruction with an autograft or allograft, and arthroscopic repair. Open direct repair is commonly used for patients with sufficient ligament quality. Reconstruction incorporating either an autograft or an allograft is another promising option in the short term, although the longevity of this procedure remains unclear. Use of an allograft avoids donor site morbidity, but it comes with inherent risks. Arthroscopic repair of chronic lateral ankle instability can provide good to excellent short- and long-term clinical outcomes, but the evidence supporting this technique is limited. Deterioration of the ankle joint after surgery is also a concern. Studies are needed on not only treating ligament insufficiency but also on reducing the risk of ankle joint deterioration.

Lateral Ankle Instability

Background. Ankle sprains are one of the most common injuries in both athletes and the general population. A major problem accompanying ankle injury is the high rate of recurrence, with about 20% of acute ankle sprain patients developing chronic ankle instability. Unlike acute ankle sprain, chronic ankle instability usually needs surgical intervention. Various anatomic reconstruction techniques using the ruptured ends of the ligaments to restore stability have gained popularity. The purpose of this study was to evaluate the functional results of the treatment of chronic lateral ankle instability with anatomic repair of the injured ligaments and reinforcement with polyester tape. Material and methods. A prospective study of 30 consecutive patients who underwent anatomic reconstruction of the lateral ligaments using transosseous suturing and augmentation using a polyester tape done at a single centre by a single surgeon from 2016 to 2017. All patients were assessed preoperatively and postoperatively at 6 weeks, 3, 6 and 12 months. The American Orthopaedic Foot and Ankle Score (AOFAS) and Free Online Foot and Ankle Ability Measure (FAAM) were recorded and used for results analysis. Results. At 12 months’ follow-up, the AOFAS had improved from mean 52.47 ± 2.06 to 91.0 ± 6.03 (p< 0.001) .The FAAM mean score had improved from mean 55.21± 1.9 to 90.43 ± 4.02 Conclusion. The ankle ligament reconstruction with additional polyester tape augmentation is an effective technique in treating chronic ankle instability with a satisfactory surgical outcome.

Abstract Context: Because motions of one segment affect those of an adjacent segment, biomechanical studies must thoroughly investigate the kinematics and kinetics of the proximal joint as well as the ankle joints in patients with chronic ankle instability (CAI). However, there have been few investigations on the altered movement strategies of the lower extremities of patients with CAI compared with lateral ankle sprain (LAS) copers and controls throughout the full gait cycle of walking and jogging. Objective: To investigate biomechanical differences of the lower extremity in those with CAI, LAS copers, and controls during gait. Design: Case-control study. Setting: Controlled laboratory setting. Patients or Other Participants: Eighteen individuals with CAI (age: 24.6 ± 2.8, height: 173.0 ± 8.0, weight: 67.8 ± 14.6), eighteen LAS copers (age: 26.0 ± 4.6, height: 173.4 ± 7.5, weight: 66.9 ± 10.3), and eighteen controls (age: 26.2 ± 2.3, height: 172.2 ± 8.2, weight: 63.3 ± 11.2). Main Outcome Measure(s): Three-dimensional (3D) kinematics and kinetics of the lower extremity during walking and jogging. Results: Individuals with CAI exhibited dorsiflexion deficits and greater inverted ankles, compared with LAS copers and controls, during walking and jogging. In addition, LAS copers generated greater knee internal rotator moments than individuals with CAI. There were no differences in other variables between groups. Conclusions: Given the results from this study, participants with CAI demonstrated altered biomechanics, which needs addressing through intervention programs.
