An ankle sprain is one of the most common injuries in tennis. It occurs when the ligaments that stabilize the ankle are stretched or torn, usually when the foot suddenly rolls inward or outward.
Tennis players are particularly vulnerable because the sport requires rapid changes of direction, explosive lateral movement, sudden stops, split steps, and quick recovery movements.
An ankle sprain can range from a mild ligament stretch to a complete ligament tear. Returning to tennis too soon can increase the risk of recurrent sprains and chronic ankle instability.
Symptoms
Common symptoms of an ankle sprain include:
- Pain around the ankle, especially when walking or putting weight on the foot
- Swelling
- Bruising
- Tenderness around the injured ligaments
- Reduced ankle movement
- Difficulty pushing off or changing direction
- Feeling that the ankle is weak or unstable
- In more severe injuries, difficulty standing or walking
The severity of symptoms does not always perfectly indicate the severity of the ligament injury. Persistent pain, significant swelling, or inability to bear weight should be evaluated by a healthcare professional.
Causes
Tennis-related ankle sprains commonly occur during:
- Sudden lateral movements
- Rapid changes of direction
- Landing awkwardly after a jump
- Stepping on another player's foot
- Losing balance while reaching for a ball
- Sudden stops and starts
- Playing on a slippery, uneven, or poorly maintained court
- Wearing inappropriate or excessively worn tennis shoes
- Returning to sport before a previous ankle injury has fully recovered
The most common ankle sprain involves the ligaments on the outside of the ankle.
Diagnosis
A healthcare professional will usually examine the ankle and ask how the injury happened.
Assessment may include:
- Checking swelling and bruising
- Identifying areas of tenderness
- Testing ankle movement
- Assessing stability
- Checking the ability to bear weight
- Comparing the injured ankle with the uninjured side
X-rays may be recommended when there is concern about a fracture. Other imaging, such as MRI, may be considered when a significant ligament injury or another structural problem is suspected.
A severe ankle injury should not automatically be assumed to be a simple sprain.
Treatment
Treatment depends on the severity of the injury.
First Stage: Protect the Injury
Initially, reduce activities that increase pain and protect the ankle from further injury. Depending on the severity, a brace, supportive taping, or temporary immobilization may be appropriate.
Control Pain and Swelling
Rest from painful activity, elevation, and appropriate compression can help manage swelling. Ice may provide short-term pain relief for some athletes.
Pain medication should be used according to appropriate medical guidance, particularly if there are other health considerations.
Restore Movement
Once pain allows, gentle ankle movement should be introduced rather than keeping the ankle completely still for an unnecessarily long period.
The goal is to gradually restore normal ankle range of motion.
Strength and Balance
Rehabilitation should progress to:
- Calf strengthening
- Ankle strengthening
- Single-leg balance
- Proprioception exercises
- Controlled hopping
- Sport-specific movement
Balance and neuromuscular training are particularly important because they can help reduce the risk of another ankle sprain.
Prevention
Tennis players can reduce their risk by maintaining good ankle strength, balance, mobility, and movement control.
Important prevention strategies include:
- Warm up before playing
- Strengthen the calves and muscles around the ankle
- Practice single-leg balance
- Perform agility and movement drills
- Use properly fitted tennis shoes
- Replace excessively worn footwear
- Be cautious on wet or slippery courts
- Consider ankle taping or bracing if recommended after a previous sprain
- Complete rehabilitation after an ankle injury
- Do not return to competitive tennis simply because the swelling has gone down
A previous ankle sprain is an important risk factor for another sprain, so proper rehabilitation is more valuable than simply waiting for pain to disappear.
Return to Tennis
Returning to tennis should be based on function rather than a fixed number of days.
Before returning to full tennis, the player should ideally be able to:
- Walk and jog without significant pain
- Move the ankle through an adequate range of motion
- Perform single-leg balance comfortably
- Complete calf raises without significant pain
- Hop and land under control
- Perform lateral movements
- Accelerate and stop without significant pain or instability
- Complete tennis-specific footwork drills
- Train progressively without a significant increase in pain or swelling afterward
Gradual Return
A sensible progression can be:
Stage 1: Walking and basic mobility
Stage 2: Jogging and controlled running
Stage 3: Lateral movement and agility drills
Stage 4: Tennis footwork without full-intensity hitting
Stage 5: Controlled tennis practice
Stage 6: Full-intensity practice
Stage 7: Competitive match play
If pain, swelling, instability, or loss of function returns during progression, the player should step back to the previous level and seek professional assessment if symptoms persist.
When to Seek Medical Attention
Medical evaluation is particularly important when:
- The player cannot bear weight
- There is severe swelling or bruising
- The ankle looks deformed
- Pain is severe or worsening
- There is significant tenderness over the bones
- The ankle repeatedly gives way
- Numbness or unusual weakness develops
- Symptoms are not improving as expected
A tennis player should not assume that every ankle injury is a simple sprain. Fractures, tendon injuries, cartilage injuries, and high-ankle sprains can produce similar symptoms.
Final Takeaway
An ankle sprain can temporarily take a tennis player away from the court, but proper rehabilitation can help restore strength, balance, movement, and confidence.
The biggest mistake is often returning to tennis because the ankle feels better before it is ready for explosive tennis movements.
For tennis players, recovery should progress from pain-free daily movement to running, lateral movement, jumping, tennis-specific footwork, practice, and finally competition.
