Ankle Sprains and Recurrent Ankle Instability in Atlanta
Most ankle sprains heal without surgery. The important questions are which ligaments were injured, whether the ankle is stable, whether the foot shape contributes to repeat injury and whether cartilage or tendon damage is also present.
What Is a Low Ankle Sprain?
A low ankle sprain involves the ligaments around the ankle joint itself. Most occur when the foot rolls inward, injuring the ligaments on the outside of the ankle.
The anterior talofibular ligament, or ATFL, is the ligament most commonly sprained. More severe injuries may also involve the calcaneofibular ligament, or CFL. The deltoid ligament supports the inner side of the ankle and may be injured in outward-rolling or more complex injuries.
Low Ankle Sprain vs. High Ankle Sprain
A low ankle sprain usually involves the ATFL and CFL near the outside of the ankle. A high ankle sprain involves the syndesmosis—the ligaments connecting the tibia and fibula above the ankle joint.
High ankle sprains usually cause pain above the ankle and pain with twisting. Recovery is often longer, and an unstable syndesmotic injury may require surgical fixation. This page primarily focuses on low ankle sprains.
The Main Ankle Ligaments
MRI reports often use these abbreviations.
ATFL
The anterior talofibular ligament is the most commonly injured ligament during a typical inward-rolling ankle sprain.
CFL
The calcaneofibular ligament may be partially or completely torn in a more severe lateral ankle sprain.
Deltoid Ligament
The deltoid ligament supports the inner ankle and may be injured during outward rolling, fractures or more complex instability.
Ankle Sprain Grades: Grade 1 Through Grade 3
The grade describes the amount of ligament damage, but the examination determines how stable and functional the ankle actually is.
Grade 1: Mild Sprain
The ligament is stretched with small fiber injuries. MRI language may include mild sprain, low-grade sprain or low-grade partial tear.
Swelling is usually limited, and the ankle generally remains stable.
Grade 2: Partial Tear
A larger portion of the ligament is torn, but it remains partly intact. MRI may describe a moderate sprain, partial-thickness tear or high-grade partial tear.
Bruising, swelling, difficulty walking and some looseness are more common.
Grade 3: Complete Tear
The ligament is fully torn. Reports may use complete rupture, full-thickness tear or complete disruption.
The ankle may be very swollen and unstable, but even many complete tears are initially treated without surgery.
We Assess the Entire Foot and Ankle
The torn ligament is only part of the problem. Foot shape and alignment can influence whether an ankle heals normally or continues to roll.
A high-arched foot may tilt inward and overload the outside ligaments. A flat foot creates a different mechanical pattern. We also consider the patient's sport, occupation and required level of function.
Treatment of an Acute Ankle Sprain
Most new low ankle sprains are treated without surgery. The goal is to protect the ankle briefly and then begin rehabilitation before stiffness and weakness become established.
Walking Boot
More painful Grade 2 or Grade 3 injuries may benefit from a short period in a walking boot to protect the ankle and make walking more comfortable.
Lace-Up Ankle Brace
As pain and swelling improve, patients often transition to a lace-up brace for walking, work and sports.
Aggressive Physical Therapy
Therapy restores motion, strengthens the ankle and peroneal tendons, improves balance and retrains proprioception so the ankle can react before it rolls again.
Recurrent Sprains and Chronic Instability
Chronic ankle instability simply means that the ankle continues to roll, give way or sprain repeatedly after the original injury.
Most recurrent cases should still undergo a serious course of bracing and aggressive rehabilitation. Surgery becomes more likely when the ankle remains mechanically unstable despite appropriate treatment.
Cartilage Damage Can Cause Pain After an Ankle Sprain
An ankle sprain can injure more than the ligaments. The talus or another joint surface may develop an osteochondral lesion, cartilage defect or loose cartilage fragment.
Patients may notice deep ankle pain, persistent swelling, catching, clicking, locking or pain that does not improve after the ligament should have healed. MRI may be needed to identify these injuries.
When loose cartilage, scar tissue or a symptomatic cartilage lesion remains inside the ankle, ankle arthroscopy may be required. Through small incisions, the joint can be inspected and loose fragments, inflamed tissue or unstable cartilage can be removed or treated. Arthroscopy may be performed alone or together with ligament stabilization.
When Is Ankle Ligament Surgery Considered?
Surgery is generally reserved for severe or recurrent instability that has not improved with appropriate nonsurgical treatment.
Ligament Repair
When the remaining ligament tissue is healthy, the lateral ligaments may be tightened and repaired back to bone.
Ligament Reconstruction
Poor-quality tissue, longstanding instability or severe injury may require reconstruction using tendon tissue.
Combined Treatment
Arthroscopy, cartilage treatment, tendon surgery or correction of contributing alignment may be performed when needed.
Return to Sports Depends on the Injury Grade
Return is based on pain, motion, strength, balance, stability and sport-specific function—not simply a fixed number of days.
Grade 1
Minor sprains may return relatively quickly once walking, jogging, cutting and sport-specific movement are pain-free and stable.
Grade 2
Partial tears generally need more protection and rehabilitation before running, jumping and cutting can safely resume.
Grade 3
Complete tears usually require a longer recovery, progressive bracing and more extensive therapy before return to sport.
When Should an Ankle Sprain Be Evaluated?
Seek orthopedic evaluation when you cannot bear weight, swelling or bruising is severe, pain is directly over the bone, pain occurs above the ankle, the ankle repeatedly gives way, symptoms persist despite treatment, or the joint catches or locks.
Ankle Sprain and Instability Care in Atlanta
Atlanta Bone and Joint Specialists evaluates acute ankle sprains, repeat sprains and chronic ankle instability for patients from Atlanta, Decatur, Snellville, Loganville and surrounding communities. We assess the ligaments, foot shape, alignment, functional demands and ankle cartilage before recommending a boot, brace, aggressive therapy, arthroscopy or ligament surgery.
