Lateral Ankle Sprain and Platelet Rich Plasma

September 30, 2019 updated by: Carlos A Acosta-Olivo, Universidad Autonoma de Nuevo Leon

Platelet Rich Plasma and Lateral Ankle Sprain. A Comparative Study

Lateral ankle sprains are one of the most common in sports medicine. Considering the sprains in general, they represent an 85% of the ankle lesions. The incidence in high performance athletes range from 16 to 21%. It is estimated that 10,000 to 25,000 peoples suffers a lateral ankle sprain per hour in the United States. The objective of the treatment is to normalize the articular function and allow the patient to return to his or her normal physical activities. Platelet rich plasma is a simple of autologous blood with concentrations of platelets above baseline values. This is rich in platelet derived growth factor which stimulates cell replication, angiogenesis, transforming growth factor B1, fibroblast growth factor, epidermal growth factor, and insulin like growth factor. The risks of its applications are minimal and are usually involved with allergic reactions to other medications that are applied in combination with the platelet-rich plasma.

To establish that the use of platelet rich plasma and immobilization with a short leg cast in acute lateral ankle sprains will enhance an early recovery in comparison with just immobilization with the cast.

Detailed Description

Lateral ankle sprains are one of the most common in sports medicine. Considering the sprains in general, they represent an 85% of the ankle lesions. The incidence in high performance athletes range form 16 to 21%. It is estimated that 10,000 to 25,000 suffers a lateral ankle sprain per hour in the United States. The objective of the treatment is to normalize the articular function and allow the patient to return to his or her normal physical activities.

The lateral ligamentous complex of the ankle consists of three ligaments: the anterior talofibular, the calcaneofibular, and the posterior talofibular. The anterior talofibular ligament is the most affected. The patient describes a tear sensation in the ankle after an acute inversion of it. The injuries occur during physical activities as running. The patients presents with pain, swelling and tenderness over the affected ligaments. The proper diagnosis of the sprain includes anteroposterior, lateral and mortise view X rays of the affected ankle; if there is any suspicion of instability of the ankle, the physician shall order a Magnetic Resonance Image (MRI) to evaluate the ligaments.

Lateral ankle sprains have been classified by numerous methods. By anatomic site, lateral ankle sprains can be classified as grade I: anterior talofibular sprain, grade II: anterior talofibular and calcaneofibular sprains, and grade III: anterior talofibular, calcaneofibular and posterior talofibular sprains. By clinical system the sprains can be classified as mild with minimal function loss, no limp, minimal swelling, tenderness, pain with reproduction of mechanism of injury; moderate with moderate functional loss, unable to rise on toes, limp when walking, localized swelling; and severe with diffuse tenderness, patient use crouches for ambulation.

Conventional treatment for lateral ankle sprains is conservative, but a 32% of the patients have chronic complications as edema, pain, and ankle instability. The treatment for acute sprains have good to excellent results. Ankle dorsiflexion allows the fibers of the affected ligament to approximate and gives stability of the ankle. The first phase of the treatment requires rest, immobilization, compression with orthesis, and the use of non steroidal anti-inflammatory drug.

Platelet rich plasma is a sample of autologous blood with concentrations of platelets above baseline values, is rich in platelet derived growth factor which stimulates cell replication, angiogenesis, transforming growth factor beta-1, fibroblast growth factor, epidermal growth factor, and insulin like growth factor. The risks of its applications are minimal and are usually involved with allergic reactions to other medications that are applied in combination with the platelet rich plasma.

Purpose To establish that the use of platelet rich plasma and immobilization with a short leg cast in acute lateral ankle sprains will enhance an early recovery in comparison with just immobilization with the cast.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Short leg cast
The patients in this group will be immobilize with a short leg cast for 14 days, and later they will be able to do physical rehabilitation and will be evaluated with American Orthopedic Foot and Ankle Society´s Ankle Hindfoot scale and Foot and Ankle Disability Index.
Other: Short leg cast
Immobilization with short leg cast with a dorsiflexed foot for two weeks
Experimental: Platelet-rich plasma
In this group, the patients will be receive a single dose of autologous platelet-rich plasma, and will be immobilized with a short leg cast. Posteriorly, they will be evaluated with American Orthopedic Foot and Ankle Society´s Ankle Hindfoot scale and Foot and Ankle Disability Index.
Procedure: Platelet-rich plasma
Will be applied 5 mL of autologous platelet-rich plasma under the lateral malleolus, over the anterior talofibular ligament

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale (AOFAS)
Time Frame: Sixth month
Scale that evaluates pain, function and alignment of foot. The best score is 100 points, and the worst score are 0 points.
Sixth month

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Analogue Scale
Time Frame: Sixth month
Evaluate the pain in a scale of 0 to 10, when 0 is no pain, and 10 is the worst pain
Sixth month
Foot and Ankle Disability Index (FADI)
Time Frame: Sixth month
The Foot and Ankle Disability Index (FADI) assesses activities such as standing, walking on flat or uneven surfaces, walking on inclines, and the length of time of walking without difficulty. It also includes a section for sports activities and ankle or foot pain (or both). The highest score is 136 points, indicating the best clinical situation, free of pain and limitations, while the lowest score is 0.
Sixth month
