Return to sports: Rate and time after arthroscopic surgery for chronic lateral ankle instability

Exploring influences and risk of bias of studies on return to sport and work after lateral ankle sprain: A systematic review and meta-analysis

BACKGROUND

Lateral ankle sprains are the most common traumatic musculoskeletal injuries of the lower extremity, with an incidence rate of 15%-20%. The high incidence and prevalence highlights the economic impact of this injury. Ankle sprains lead to a high socioeconomic burden due to the combination of the high injury incidence and high medical expenses. Up to 40% of patients who suffer from an ankle sprain develop chronic ankle instability. Chronic instability can lead to prolonged periods of pain, immobility and injury recurrence. Identification of factors that influence return to work (RTW) and return to sports (RTS) after a lateral ankle sprain (LAS) may help seriously reduce healthcare costs.

AIM

To explore which factors may potentially affect RTW and RTS after sustaining an LAS.

METHODS

EMBASE and PubMed were systematically searched for relevant studies published until June 2023. Inclusion criteria were as follows: (1) Injury including LAS or chronic ankle instability; (2) Described any form of treatment; (3) Assessment of RTW or RTS; (4) Studies published in English; and (5) Study designs including randomized controlled clinical trials, clinical trials or cohort studies. Exclusion criteria were: (1) Studies involving children (age < 16 year); or (2) Patients with concomitant ankle injury besides lateral ankle ligament damage. A quality assessment was performed for each of the included studies using established risk of bias tools. Additionally quality of evidence was assessed using the GRADEpro tool in cases where outcomes were included in the quantitative analysis. A best evidence synthesis was performed in cases of qualitative outcome analysis. For all studied outcomes suitable for quantitative analysis a forest plot was created to calculate the effect on RTW and RTS.

RESULTS

A total of 8904 patients were included in 21 studies, 10 randomized controlled trials, 7 retrospective cohort studies and 4 prospective cohort studies. Fifteen studies were eligible for meta-analysis. The overall RTS rate ranged were 80% and 83% in the all treatments pool and surgical treatments pool, respectively. The pooled mean days to RTS ranged from 23-93 d. The overall RTW rate was 89%. The pooled mean time to RTW ranged from 5.8-8.1 d. For patients with chronic ankle instability, higher preoperative motivation was the sole factor significantly and independently (P = 0.001) associated with the rate of and time to RTS following ligament repair or reconstruction. Higher body mass index was identified as a significant factor (P = 0.04) linked to not resuming sports or returning at a lower level (median 24, range 20-37), compared to those who resumed at the same or higher level (median 23, range 17-38). Patients with a history of psychological illness or brain injury, experienced a delay in their rehabilitation process for sprains with fractures and unspecified sprains. The extent of the delayed rehabilitation was directly proportional to the increased likelihood of experiencing a recurrence of the ankle sprain and the number of ankle-related medical visits. We also observed that 10% of athletes who did return to sport after lateral ankle sprain without fractures described non-ankle-related reasons for not returning.

CONCLUSION

All treatments yielded comparable results, with each treatment potentially offering unique advantages or benefits. Preoperative motivation may influence rehabilitation after LAS. Grading which factor had a greater impact was not possible due to the lack of comparability among the included patients.

Perioperative duloxetine improves postoperative outcomes after anterior talofibular ligament repair for chronic lateral ankle instability for patients with depression: A prospective randomized clinical trial

BACKGROUND

Recent studies have indicated that depression is associated with persistent postoperative pain and decreased satisfaction following foot and ankle surgery. This study aimed to evaluate the effect of perioperative duloxetine on postoperative outcomes of anterior talofibular ligament (ATFL) surgical repair for chronic ankle instability (CAI) in patients with depression. We further sought to evaluate patients' satisfaction and side effects related to duloxetine.

MATERIAL AND METHODS

Patients undergoing ATFL repair were screened for depression preoperatively with the Patient Health Questionnaire (PHQ-9). Among 249 patients who underwent arthroscopic or open surgical Brostrom repair of the ATFL, 120 patients were identified as being "possibly depressed" and were included in the study. Sixty patients were randomly assigned to the duloxetine group (one day preoperatively and for 6 weeks postoperatively), and the other sixty were randomized to the placebo group. Painkillers and opioid consumption, pain scores, and patient satisfaction were recorded at 12, 24, 48, and 72hours postoperatively and at follow-up visits 1, 3, and 6 months after surgery. Patient-reported outcome measures (PROMs) were assessed preoperatively and at 3, 6, 12 and 24 months postoperatively. Duloxetine-related side effects such as nausea/vomiting and fatigue were also recorded.

RESULTS

The patients in the duloxetine group reported a significantly longer time to rescue analgesic and reduced opioid requirements (including celecoxib, pregabalin, acetaminophen, and tramadol). The patients experienced decreased pain intensity and greater satisfaction with their pain management at 24, 48, 72h and 1 and 3 months after surgery (p<0.05). The duloxetine group also had significantly better clinical and functional outcomes at 3 and 6 months of follow-up compared to the placebo group (p<0.05). The occurrence and rate of symptoms of duloxetine side effects were not significant.

DISCUSSION

Depression is an important factor to consider and address because its presence before surgery can predict poor postoperative outcomes, including more severe postoperative pain, persistent postoperative pain, and increased consumption of painkillers and opioids.

CONCLUSION

Perioperative administration of duloxetine following ATFL repair for CAI in patients with depression increased the time to first postoperative rescue analgesic request and reduced both opioid consumption and postoperative pain. This approach also led to a high level of patient satisfaction. In addition, duloxetine improved the quality of recovery without leading to significant side effects.

Development and Validation of the Ankle-GO Score for Discriminating and Predicting Return-to-Sport Outcomes After Lateral Ankle Sprain

BACKGROUND

Lateral ankle sprain (LAS) is the most common sports-related injury. However, there are currently no published evidence-based criteria to guide the patient's return to sport (RTS) and this decision is generally time-based. The aim of this study was to assess the psychometric properties of a new score (Ankle-GO) and its predictive ability for RTS at the same level of play after LAS.

HYPOTHESIS

The Ankle-GO is robust for discriminating and predicting RTS outcomes.

STUDY DESIGN

Prospective diagnostic study.

LEVEL OF EVIDENCE

Level 2.

METHODS

The Ankle-GO was administered to 30 healthy participants and 64 patients at 2 and 4 months after LAS. The score was calculated as the sum of 6 tests for a maximum of 25 points. Construct validity, internal consistency, discriminant validity, and test-retest reliability were used to validate the score. The predictive value for the RTS was also validated based on the receiver operating characteristic (ROC) curve.

RESULTS

The internal consistency of the score was good (Cronbach's alpha coefficient of 0.79) with no ceiling or floor effect. Test-retest reliability was excellent (intraclass coefficient correlation = 0.99) with a minimum detectable change of 1.2 points. The 2-month scores were significantly lower than 4-month and control group scores (7.7 ± 4, 13.9 ± 4.6, and 19.6 ± 3.4 points, respectively, P < 0.01). Ankle-GO values were also significantly higher in patients who returned to their preinjury level at 4 months compared with those who did not (P < 0.01). The predictive value of the 2-month Ankle-GO score was fair for a RTS at the same or higher than preinjury level at 4 months (area under ROC curve, 0.77; 95% CI, 0.65-0.89; P < 0.01).

CONCLUSION

The Ankle-GO appears to be a valid and robust score for clinicians to predict and discriminate RTS in patients after LAS.

CLINICAL RELEVANCE

Ankle-GO is the first objective score to help in the decision-making of the RTS after LAS. At 2 months, patients with an Ankle-GO score <8 points are unlikely to RTS at the same preinjury level.

Return to sport after surgery for osteochondral lesions of the talar dome. Results of a multicenter prospective study on 58 patients

INTRODUCTION

Osteochondral lesions of the talar dome (OLTD) are most often found in patients for whom the return to sports activities is the main issue. Two types of surgery have been distinguished at present, bone marrow stimulation techniques and mosaicplasty techniques. The size of the lesion indicating the need for bone marrow stimulation as the required surgical procedure has recently been decreased (<1cm). The main objective of this study was therefore to evaluate the return to sport after OLTD surgery. Our hypothesis is that surgery of osteochondral lesions of the talar dome allows the resumption of sports activities in the majority of cases.

MATERIAL AND METHODS

This multicenter prospective study was conducted across 10 French centers specializing in foot and ankle surgery. All patients aged 18 to 65 with symptomatic OLTD resistant to thorough medical treatment for at least 6 months, justifying surgery, were included from June 2018 to September 2019. In addition to the usual demographic data, the practice of sport and level (professional, competitive, leisure) were systematically investigated preoperatively. A common protocol for surgical management and postoperative follow-up had previously been established according to the arthrographic stage of the lesion. The most recent recommendations based on size, but also depth, were taken into account. The primary endpoint was return to sport.

RESULTS

A final functional evaluation with the AOFAS (American Orthopedic Foot & Ankle Society) score was performed at a minimum of 12 months. Of 58 sports patients, 70.6% returned to sport (41/58) with an average delay of 4.3 months. A high AOFAS functional score (p=0.02) and a stage 1 lesion (p=0.006) were the only preoperative criteria significantly associated with a return to sport. No other factor was predictive of a return to sport.

CONCLUSION

Our prospective study shows that 70.6% of sports patients returned to sport after OLTD surgery according to a surgical protocol and standardized follow-up.
