Ankle Sprain/Instability
Ankle Sprain and Chronic Ankle Instability Treatment in Frisco, Texas
An ankle sprain occurs when one or more ligaments supporting the ankle are stretched or torn. Most sprains involve the ligaments on the outside of the ankle and happen when the foot suddenly rolls inward. High ankle sprains affect a different group of ligaments above the ankle and may require a longer recovery.
Symptoms can include pain, swelling, bruising, tenderness, stiffness, and difficulty bearing weight. The severity of an ankle sprain depends on which ligaments are injured and whether they are stretched, partially torn, or completely torn.
Why an Ankle Sprain Should Be Evaluated
An ankle fracture, cartilage injury, tendon tear, or high ankle sprain can produce symptoms similar to those of a routine sprain. Walking on the injured ankle does not necessarily rule out a significant injury.
An improperly treated sprain can also lead to persistent weakness and chronic ankle instability. Early diagnosis and an appropriate rehabilitation plan can help the ligaments heal while restoring strength, balance, and control.
Diagnosing an Ankle Sprain
Dr. Woojung Lee will review how the injury occurred and examine the ankle for swelling, tenderness, bruising, instability, and loss of motion. The evaluation may also include the foot and lower leg to identify associated injuries.
Diagnostic testing may include:
• On-site X-rays to look for a fracture, joint misalignment, or another bone injury
• Stress X-rays to evaluate ligament-related instability in selected cases
• Ultrasound to assess certain ligaments or tendons
• MRI to evaluate a suspected ligament tear, tendon injury, cartilage damage, or another cause of persistent pain
Ultrasound and MRI are not required for every ankle sprain. They may be ordered when examination findings suggest a more significant injury or when symptoms do not improve as expected.
Ankle Sprain Treatment Options
Treatment depends on the severity of the injury, the ligaments involved, the patient’s activity level, and whether another injury is present. An individualized plan may include:
• Rest and temporary activity modification
• Ice, compression, and elevation
• Immobilization in a walking boot, splint, or cast
• Temporary limitation of weight-bearing
• An ankle brace or other supportive device
• Nonsteroidal anti-inflammatory medications (NSAIDs), when medically appropriate
• Physical therapy
• Balance and proprioception training
• Sport- or activity-specific rehabilitation
• Injection therapy for selected sources of persistent pain or inflammation
• Surgery for significant mechanical instability that does not respond adequately to nonsurgical treatment
Injection therapy does not mechanically repair a torn or loose ligament. When considered, the type and purpose of the injection should be based on the underlying diagnosis rather than the presence of a sprain alone.
Physical Therapy and Rehabilitation
Rehabilitation is an important part of ankle-sprain treatment. Pain and swelling may improve before the ligament, surrounding muscles, and balance system have fully recovered. Returning to sports or strenuous activity too quickly can increase the risk of another injury.
Physical therapy may focus on:
• Restoring ankle motion
• Strengthening the muscles that support the ankle
• Improving balance and joint-position awareness
• Correcting walking or running mechanics
• Gradually returning to work, exercise, and sports
• Reducing the risk of recurrent sprains
What Is Chronic Ankle Instability?
Chronic ankle instability is a recurring feeling that the ankle is weak, loose, or likely to give way. It often develops after repeated ankle sprains or after an earlier sprain that did not fully heal or receive adequate rehabilitation.
Patients may experience:
• Repeated ankle rolling or sprains
• Giving way on uneven surfaces
• Persistent pain or swelling
• Difficulty trusting the ankle during sports or exercise
• Weakness or poor balance
• Tenderness along the outside of the ankle
• A sensation that the ankle is loose or unstable
Chronic ankle pain after a sprain may also result from a tendon tear, cartilage injury, scar tissue, joint impingement, or another condition. Additional imaging may be needed to identify the source.
Nonsurgical Treatment for Ankle Instability
Many patients begin with nonsurgical treatment, which may include:
• Structured physical therapy
• Ankle strengthening and balance exercises
• Bracing during sports or higher-risk activities
• Supportive footwear
• Custom orthotics when foot structure contributes to instability
• Activity modification
• NSAIDs for short-term pain and inflammation, when appropriate
The goal is to improve muscular support, retrain balance, and reduce repeated episodes of giving way.
Modified Broström Ankle-Ligament Reconstruction
Surgery may be considered when objective mechanical instability, repeated sprains, or functional limitations continue despite an appropriate course of bracing and rehabilitation.
A modified Broström procedure repairs and tightens the damaged ligaments on the outside of the ankle. Depending on the injury, the repair may be reinforced or combined with treatment for associated tendon, cartilage, or joint problems.
The goal of surgery is to restore ankle stability and reduce the risk of recurrent giving-way episodes and additional injuries. No procedure can guarantee that another ankle injury will never occur.
Recovery varies according to the procedure and associated injuries. It commonly includes:
• A period of immobilization
• Temporary restricted or non-weight-bearing activity
• Transition into a walking boot and brace
• Physical therapy
• Gradual return to regular footwear
• Progressive return to work, exercise, and sports
When to Seek Prompt Medical Care
Seek timely evaluation if you have:
• Inability to bear weight or walk several steps
• Significant swelling, bruising, or deformity
• Numbness, color change, or coolness in the foot
• Tenderness directly over an ankle bone
• Persistent pain following an apparent sprain
• Repeated ankle instability or giving way
• A sudden pop with weakness along the outside or back of the ankle
Schedule an ankle evaluation at Modern Podiatry in Frisco if you have a new ankle sprain, lingering pain from a previous injury, or recurrent ankle instability.
