Acute ankle sprain in athletes: Clinical aspects and algorithmic approach

Acute ankle sprain is the most common lower limb injury in athletes and accounts for 16%-40% of all sports-related injuries. It is especially common in basketball, American football, and soccer. The majority of sprains affect the lateral ligaments, particularly the anterior talofibular ligament. Despite its high prevalence, a high proportion of patients experience persistent residual symptoms and injury recurrence. A detailed history and proper physical examination are diagnostic cornerstones. Imaging is not indicated for the majority of ankle sprain cases and should be requested according to the Ottawa ankle rules. Several interventions have been recommended in the management of acute ankle sprains including rest, ice, compression, and elevation, analgesic and anti-inflammatory medications, bracing and immobilization, early weight-bearing and walking aids, foot orthoses, manual therapy, exercise therapy, electrophysical modalities and surgery (only in selected refractory cases). Among these interventions, exercise and bracing have been recommended with a higher level of evidence and should be incorporated in the rehabilitation process. An exercise program should be comprehensive and progressive including the range of motion, stretching, strengthening, neuromuscular, proprioceptive, and sport-specific exercises. Decision-making regarding return to the sport in athletes may be challenging and a sports physician should determine this based on the self-reported variables, manual tests for stability, and functional performance testing. There are some common myths and mistakes in the management of ankle sprains, which all clinicians should be aware of and avoid. These include excessive imaging, unwarranted non-weight-bearing, unjustified immobilization, delay in functional movements, and inadequate rehabilitation. The application of an evidence-based algorithmic approach considering the individual characteristics is helpful and should be recommended.

A Case of Neglected Achilles Rupture after an Ankle Sprain

Lateral ankle sprains are common injuries seen by primary care and podiatric specialties. However, lateral ankle pain from a suspected inversion injury of the ankle may be more than a Grades I, II, or III ankle sprain. This case report illustrates a 30-year-old U.S. Navy Active Duty Service Member that was initially diagnosed with a "lateral ankle sprain". Upon subsequent follow-up with a podiatric foot and ankle surgeon, he was diagnosed with a 3-month-old chronic and neglected Achilles tendon rupture. The purpose of this manuscript is to present an uncommon and unique presentation of lateral ankle pain after injury, subsequent surgical treatment, as well as a review of the common differential diagnoses of "lateral ankle pain."

Prevention of Lateral Ankle Sprains

CONTEXT

Given the frequency of ankle sprains, especially in the athletic population, prevention is a primary task of athletic trainers and other sports health care professionals.

OBJECTIVE

To discuss the current evidence as it relates to prophylactic programs for the prevention of ankle sprains and to provide critical interpretation of the evidence supporting and refuting the implementation of preventive programs.

CONCLUSIONS

External prophylactic supports and preventive exercise programs are effective for reducing the risk of ankle sprains in both uninjured and previously injured populations. Ankle bracing appears to offer the best outcomes in terms of cost and risk reduction. However, there remains a paucity of well-designed, prospective randomized controlled trials relevant to the primary prevention of lateral ankle sprains, especially across a range of sport settings.

Treatment and prevention of acute and recurrent ankle sprain: an overview of systematic reviews with meta-analysis

BACKGROUND

Ankle sprains are highly prevalent with high risk of recurrence. Consequently, there are a significant number of research reports examining strategies for treating and preventing acute and recurrent sprains (otherwise known as chronic ankle instability (CAI)), with a coinciding proliferation of review articles summarising these reports.

OBJECTIVE

To provide a systematic overview of the systematic reviews evaluating treatment strategies for acute ankle sprain and CAI.

DESIGN

Overview of intervention systematic reviews.

PARTICIPANTS

Individuals with acute ankle sprain/CAI.

MAIN OUTCOME MEASUREMENTS

The primary outcomes were injury/reinjury incidence and function.

RESULTS

46 papers were included in this systematic review. The reviews had a mean score of 6.5/11 on the AMSTAR quality assessment tool. There was strong evidence for bracing and moderate evidence for neuromuscular training in preventing recurrence of an ankle sprain. For the combined outcomes of pain, swelling and function after an acute sprain, there was strong evidence for non-steroidal anti-inflammatory drugs and early mobilisation, with moderate evidence supporting exercise and manual therapy techniques. There was conflicting evidence regarding the efficacy of surgery and acupuncture for the treatment of acute ankle sprains. There was insufficient evidence to support the use of ultrasound in the treatment of acute ankle sprains.

CONCLUSIONS

For the treatment of acute ankle sprain, there is strong evidence for non-steroidal anti-inflammatory drugs and early mobilisation, with moderate evidence supporting exercise and manual therapy techniques, for pain, swelling and function. Exercise therapy and bracing are supported in the prevention of CAI.
