Modified Broström Repair With and Without Augmentation Using Suture Tape for Chronic Lateral Ankle Instability

Abstract

Objective To compare the clinical and radiological outcome between the modified Broström repair with augmentation using suture tape (MBA) and the modified Broström repair (MB) for patients with chronic lateral ankle instability. Methods A retrospective study was performed in Ningbo No. 6 Hospital. The study included 53 patients who underwent surgical treatment from March 2014 to July 2016 and were followed for 2 years. A total of 25 patients underwent modified Broström repair with augmentation using suture tape, and 28 patients were treated with modified Broström repair. Patients were evaluated using the American Orthopedic Foot and Ankle Scale (AOFAS) hindfoot scale, the Foot and Ankle Ability Measure (FAAM) score, range of motion (ROM), and the visual analogue scale (VAS). The talar tilt angle (TTA) and anterior talar translation (ATT) were used to evaluate the mechanical stability. All radiological outcomes were measured by two orthopaedic surgeons, with the measurements repeated 3 days later. Results The mean age of the patients was 26.6 ± 17.8 years in the MBA group and 28.1 ± 19.4 years in the MB group, and no statistical difference in preoperative data was found between two groups. There were significant differences before and after the operation within the groups. Both groups achieved satisfactory outcomes, and significant improvements (VAS, FAAM, AOFAS, TTA, and ATT) were observed between the 1‐year follow‐up and final follow‐up ( P < 0.05). The MBA group showed significant improvement in the FAAM Sport (87.1 ± 5.4 vs 78.2 ± 12.0, P = 0.001) and total scores (93.1 ± 2.3 vs 90.5 ± 5.1, P = 0.027) at the final follow‐up compared with the MB group, and for the other outcomes, there were no significant differences between the two groups. Conclusion The modified Broström repair with augmentation using suture tap for chronic lateral ankle instability achieves a better outcome; however, further research is necessary.

No Differences in Clinical Outcomes of Suture Tape Augmented Repair Versus Broström Repair Surgery for Chronic Lateral Ankle Instability

“…FAAM total scores were reported in 3 studies, which consisted of 83 ST patients and 86 BR patients. The mean FAAM scores were 89.4 ± 7.4 for the ST group and 92.2 ± 6.5 for the BR group in the study by Cho et al 7 ; 93 ± 13 for ST and 89.3 ± 15 for BR in the study by Ulku et al 52 ; and 93.1 ± 2.3 for ST and 90.5 ± 5.1 for BR in the study by Xu et al 59 No significant difference was found between the ST and BR groups (mean difference [MD], 0.90; 95% CI, –3.17 to 4.96; I 2 = 70%; P = .66) ( Figure 3 ).…”

“…The operation time was reported in 3 studies. Xu et al 59 reported there was no significant difference in operation time between groups but provided no detailed data. Ulku et al 52 reported that the mean operation time for the ST and BR groups was 35.2 ± 5.2 and 48.6 ± 5.6 minutes, respectively.…”

“…Postoperative AOFAS scores were reported in 2 studies, which consisted of 47 patients in the ST group and 91 patients in the BR group. Xu et al 59 reported a mean AOFAS of 97.5 ± 3.3 for the ST group and 96.3 ± 6 for the BR group. Yoo and Yang 63 reported a mean AOFAS of 98 ± 16.8 for the ST group and 96.5 ± 5.4 for the BR group.…”

“…FAAM sports activity scores were reported in 3 studies, 7 , 52 , 59 which consisted of 83 patients in the ST group and 86 patients in the BR group. No significant difference was seen between the ST and BR groups (MD, 3.24; 95% CI, –5.31 to 11.79; I 2 = 87%; P = .46) ( Figure 4 ).…”

“…Ulku et al 52 observed that 1 patient (3.3%) had recurrence in the ST group and 2 patients (6.5%) in the BR group. Xu et al 59 found 1 case of mechanical instability in the BR group, which was treated with modified BR with augmentation using ST. Coetzee et al 12 reported that 1 patient experienced ankle inversion sprains at 1 year postoperatively during basketball games, but it did not result in recurrent instability.…”
