Modified Broström Procedure

Background: Although the peroneal muscles are known to be the major dynamic lateral stabilizers of the ankle, little information is available regarding the change in muscle strength and relation with the outcomes after lateral ligament repair surgery. The purpose of this study was to identify the effects of peroneal strength on the validated functional outcome measures after the modified Broström procedure (MBP) for chronic ankle instability. Methods: Forty-one patients (41 ankles) who underwent MBP using suture anchors were eligible and followed up to 2 years postoperatively. Functional evaluation consisted of the Foot and Ankle Outcome Score (FAOS), and Foot and Ankle Ability Measure (FAAM). The changes of peroneal strength were evaluated using an isokinetic dynamometer. Differences in the functional outcomes between the 3 groups divided according to the recovery rate of peroneal strength were analyzed. Results: Peak torque and total work for eversion in 60 degrees/s angular velocity significantly improved from a mean 8.1 and 5.2 Nm preoperatively to 11.4 and 6.9 Nm at postoperative 2 years, respectively ( P < .001, P = .038). The deficit ratio of peak torque for eversion significantly improved from a mean 38.6% to 17.4%, and a significant side-to-side difference was found ( P = .011). There were no significant differences in FAOS, FAAM, and measurements of stress radiograph between the 3 groups. Conclusions: Although restoration of peroneal strength postoperatively was about 82.6% of the unaffected ankle, patient-reported function in daily and sport activities were satisfactorily improved. Postoperative isokinetic strength of the peroneals demonstrated no statistically significant effects on the functional outcomes after MBP. Level of Evidence: Level III, prospective comparative case series.

Controlled research has shown that a single-exercise wobble-board intervention is effective at reducing symptoms and increasing function in patients with chronic ankle instability. However, the effectiveness of this protocol has not been documented in a realistic intercollegiate athletics environment. Eight intercollegiate athletes with chronic ankle instability participated in an 8-week (3 sessions/wk) wobble-board intervention. In a realistic environment, this simple intervention was feasible to implement and resulted in meaningful improvements in patient-reported stability for more than half of the patients (5 of 8) but only improved the global rating of function and pain for a minority of the patients (2 of 8 and 3 of 8, respectively). Not all patients experienced equal symptom reduction; however, no new ankle sprains occurred during the intervention.

Context: Strength deficits and decreased scores on generic, dimension-specific, and region-specific health-related quality of life (HRQL) PRO measures are commonly documented among individuals with chronic ankle instability (CAI). However, it is unknown if there is a relationship between hip strength and self-reported patient-reported outcome (PRO) scores. Objective: To compare isometric peak torque for hip-extension (H-EXT) and hip-abduction (H-ABD), as well as PRO scores between CAI, lateral ankle sprain copers (LAS copers), and uninjured controls (UC). The secondary purpose was to examine the relationship between isometric hip peak torque and PROs in participants with CAI. Design: Cross-sectional. Setting: Laboratory. Participants: Sixty-three individuals, 45 women (23.02 [3.83] y, 165.91 [7.55] cm, 67.28 [11.95] kg) and 18 men (26.28 [5.43] y, 179.28 [9.01] cm, 83.87 [13.26] kg), grouped as uninjured control (n = 26), LAS coper (n = 15), or CAI (n = 22). Main Outcome Measures: The Foot and Ankle Ability Measure was used to assess region-specific HRQL. The Fear Avoidance Beliefs Questionnaire was used to assess injury-related fear. The Disablement in Physically Active was used to assess global HRQL. Isometric peak torque was measured with a handheld dynamometer for H-EXT and H-ABD. Results: No group differences were observed for H-ABD (P = .34) or H-EXT (P = .35). The CAI group had significantly worse scores on all PROs compared with LAS coper (P < .001) and HC (P < .001). Moderate–weak correlations were found between H-ABD and Foot and Ankle Ability Measure—activities of daily living (P = .047; ρ = .392) and Foot and Ankle Ability Measure-Sport (P = .013; ρ = .482) and H- EXT and Fear Avoidance Beliefs Questionnaire-Work (P = .007; ρ = −.517). Conclusions: Individuals with CAI displayed lower HRQL based on worse scores on generic, dimension-specific, and region-specific PROs compared with LAS copers and uninjured controls. There were no significant between-group differences for H-EXT and H-ABD isometric peak torque production, but there was a moderate positive relationship between isometric H-ABD and self-reported ankle disability in individuals with CAI.

Category: Sports Introduction/Purpose: Although lateral ligaments augmentation using suture-tape has been effective for restoration of mechanical ankle stability, few data are available regarding changes of peroneal strength, proprioception and postural control. The aim of this study was to determine effects of suture-tape augmentation on functional ankle instability (FAI). Methods: Twenty-four patients that underwent suture-tape augmentation were eligible and were followed more than two years postoperatively. Functional outcomes were evaluated with the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM). Changes of peroneal strength, proprioception and postural control were analyzed with an isokinetic dynamometer and a modified Romberg test. Results: CAIT and FAAM significantly improved to average 27.2 points, 86.7 points at final followup. Peak torque for eversion in 60º/sec angular velocity significantly improved to 10.6 Nm at final followup. Deficit ratio of peak torque for eversion significantly improved from mean 39.5% to 20.9%, and significant side to side difference was revealed (P < .001). There were no significant differences in joint position sense. A significant improvement in balance retention time was revealed at final followup and relative deficit ratio compared to unaffected side was 30.9%. Conclusion: Patient-reported functional outcomes significantly improved after lateral ligaments augmentation using suture-tape. Although this procedure demonstrated significant effects on FAI based on improvement of isokinetic peroneal strength and postural control, recovery rates compared to the unaffected side were insufficient at the intermediate-term followup. In addition, there was no significantly positive effect on proprioception of the ankle.

The study objective was to develop a shortened version of the Foot and Ankle Ability Measure (FAAM) for individuals with chronic ankle instability (CAI). Forty individuals with CAI completed the FAAM Activities of Daily Living and Sport subscales and the Short Form-12. Analyses were completed for item reduction followed by dimensionality, coverage redundancy, and internal consistency of a reduced-item instrument. Validity was examined through correlations with the original FAAM and Short Form-12. A 12-item FAAM was created which demonstrated strong internal consistency and convergent/divergent validity. The Quick-FAAM may provide an alternative patient-reported outcome for CAI which requires less administration time.

Modified Broström Procedure

Background: There is limited information regarding the outcomes of operative treatment for ankle instability with coexisting arthritic changes in the medial gutter. This study was performed to evaluate the intermediate-term clinical and radiological outcomes following a modified Broström procedure and arthroscopic debridement in middle-aged patients with combined medial gutter osteoarthritis and chronic ankle instability. Methods: Twenty-two patients with medial gutter osteoarthritis related to chronic lateral ankle instability were followed for more than 3 years after operative treatment. All patients showed medial joint space narrowing of Takakura stage II at the time of surgery. The clinical evaluation consisted of the American Orthopaedic Foot & Ankle Society (AOFAS) score, visual analog scale (VAS) for medial ankle pain during walking, and Foot and Ankle Ability Measure (FAAM). Results: Mean AOFAS and FAAM scores significantly improved from 51.2 and 45.7 points preoperatively to 80.3 and 78.4 points at final follow-up, respectively ( P < .001). Although mean pain-VAS significantly improved from 6.8 points to 3.5 points ( P < .001), 8 patients (36.4%) complained of gait discomfort with considerable pain of 4 or more points. There was only 1 patient (4.5%) with recurrent ankle instability, while 6 patients (27.3%) showed a progression of arthritis stage. Conclusions: Modified Broström procedure combined with arthroscopic debridement appears to be an effective operative option for medial gutter osteoarthritis secondary to chronic ankle instability. Despite the onset of arthritis, most patients were able to achieve significant improvement in reducing pain while eliminating instability. Level of Evidence: Level IV, retrospective case series.

Category: Ankle Arthritis Introduction/Purpose: Although the frequent intraarticular pathologies associated with recurrent ankle sprains are well known, informations regarding treatment method for arthritic changes in the medial gutter are still insufficient. This study was performed to evaluate the intermediate-term clinical and radiological outcomes following modified Broström procedure and arthroscopic debridement in the middle-aged patients. Methods: Twenty-two patients with medial gutter osteoarthritis related to chronic lateral ankle instability were followed for more than 3 years after surgical treatment. All patients showed medial joint space narrowing of Takakura stage 2. The clinical evaluation consisted of the American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS) for medial ankle pain during walking, and Foot and Ankle Ability Measure (FAAM). Results: Mean AOFAS and FAAM scores significantly improved from 51.2 and 45.7 points preoperatively to 80.3 and 78.4 points at final followup, respectively (P < .001). Although mean pain-VAS significantly improved from 6.8 points to 3.5 points (P < .001), 8 patients (36.4%) complained of discomfort at gait with considerable pain ≥ 4 points. There was only 1 patient (4.5%) with recurrent ankle instability, while 6 patients (27.3%) showed a progression in arthritis stage. Conclusion: Modified Broström procedure concomitant with arthroscopic debridement for medial gutter osteoarthritis secondary to chronic ankle instability is not effective enough to treat the medial ankle pain and functional impairment. Alternative treatment strategies for middle-aged cohort with arthritic changes are needed to improve the clinical outcomes and to prevent a progressive osteoarthritis.

Objective: To analyze the functional outcomes of patients undergoing endoscopic calcaneoplasty for the treatment of Haglund deformity. Methods: This study consists of a case series of patients undergoing endoscopic calcaneoplasty. The American Orthopaedic Foot and Ankle Society ankle-hindfoot scale, was used to evaluate patients before and 12 months after the procedure, providing preoperative and postoperative scores. Results: Nineteen patients were evaluated for a total of 24 endoscopic calcaneoplasties. The American Orthopaedic Foot and Ankle Society scale provided a mean preoperative score of 31.4 and a mean postoperative score of 93.3, which shows a significantly increased score after surgery. The mean patient age was 52 years, and the youngest patient was 25 years old and the oldest patient was 73 years old. However, no significant relationship was found between age and change in the American Orthopaedic Foot and Ankle Society score. No complications were observed in the immediate or late postoperative periods. Conclusion: Arthroscopic resection is efficient in the treatment of Haglund deformity given the significant improvement in the American Orthopaedic Foot and Ankle Society score observed after the procedure. Also, no postoperative complications were seen in patients who underwent endoscopic calcaneoplasty. Level of Evidence: IV; Therapeutic Studies; Case series.
