Chronic ankle instability

What it is

After a lateral sprain, something like a third to a half of players end up with an ankle that keeps giving way, keeps aching, or simply cannot be trusted. Two things are going on. The mechanical part is that a torn ligament heals long and slack, so the joint has more play in it than it should. The functional part is bigger: that ligament was full of sensors telling your brain where the foot was in space, the reflex loop that fires the muscles on the outside of the shin got slower, and those muscles got weaker while you were limping around. The result is an ankle that is a bit loose and, more importantly, a bit late.

How volleyball causes it

The pattern is almost always identical. A player sprains an ankle, waits until the swelling and pain are gone, which takes one to three weeks, then goes straight back to blocking, because pain going away feels like healing. Nothing has restored the reflex speed, the peroneal strength, or the ankle's forward bend, so the foot now sits slightly more tilted in the air and lands already inverted, with slower brakes behind it. Volleyball then serves up the exact same hazard, a blind landing among feet at the net, hundreds of times a season, and each fresh roll takes another bite out of the ligament and the reflex loop. One sprain becomes three, and then it starts giving way on stairs and flat ground, which is usually when players finally take it seriously.

What it feels like

• The ankle rolls on flat ground, on stairs, or stepping off a kerb, not just in the middle of a play
• A constant sense that the ankle cannot be trusted, and reluctance to land single leg on that side
• Playing without a brace or tape stops feeling like an option
• Puffiness around the ankle after most sessions, and a dull ache at the front of the joint
• Less forward bend on that side, so a deep squat or a knee-to-wall test is clearly short
• Clicking, catching, or a pinching sensation deep in the joint

Stop and get it seen if

• Catching, locking, or a sharp deep pinch inside the joint with swelling out of proportion to activity, which can mean a piece of cartilage and bone on the talus has been damaged (osteochondral lesion) and needs imaging
• Giving way while simply walking on level ground, which suggests genuine mechanical instability rather than a control problem
• Sudden loss of power turning the foot outward, or a snapping sensation behind the outside ankle knob, which points to a peroneal tendon tear or the tendon slipping out of its groove
• Pain at rest or at night, which does not fit an instability pattern at all
• Sharp pain at the back of the ankle when pointing the toes hard, which is a separate problem common in jumpers (posterior ankle impingement)

What recovery usually looks like

Stages, not a schedule. Everyone moves through these at their own pace, and the ranges are wide because real recoveries are.

1. 1. Settle the latest episode and find the real deficit

   1 to 3 weeks

   Calm the current flare and get someone to work out how much of this is a loose ligament, how much is weakness and slow reactions, and whether anything inside the joint is damaged.

   • The most recent roll has settled enough to walk and train in straight lines without pain
   • There is a clear picture of which side has less forward bend, less balance, and less strength turning the foot outward
   • Bracing or taping is being used for everything, not just matches

2. 2. Rebuild strength, range, and balance

   6 to 12 weeks, and the balance work needs most of that before it takes

   Restore calf and peroneal strength, get the forward bend back, and retrain balance. This is the phase people skip, and it is the one that actually changes the reinjury rate.

   • Single leg heel raise numbers close to matching the other side
   • Standing on the injured leg with eyes closed no longer means constant correcting
   • Forward bend of the ankle is symmetric side to side
   • No new giving way episodes across this block of work

Ready to play again when

• Side to side hop and figure of eight hop times within about a tenth of the uninjured leg
• Four consecutive weeks of full training with no giving way and no swelling
• Single leg balance with eyes closed for about half a minute, matching the other side
• A block jump landed on an uneven or soft surface with no collapse
• A repeat of whatever ankle instability questionnaire a clinician scored you on at the start, showing a real change

Keeping it from coming back

This is ordinary training, so unlike the rest of this page it does tell you what to do.

• Brace or tape every session, not just matches. A lace-up brace measurably cuts recurrence in players with a previous sprain, and most sprains happen in training volume where nobody bothers taping.
• Balance work with someone interfering: partner nudges at the hip and shoulder, head turns, catching a ball thrown wide, all on one leg. Game landings happen with the eyes and the brain busy, so quiet balance on a wobble board misses the point.
• Peroneal strength: band eversion, side-lying eversion holds, and heel raises done with the weight biased through the outside toes. These muscles are the brake, and they need to be both strong and fast.
• Heavy calf raises through the full range, knee straight and knee bent, with slow lowering. Calf capacity decides how much landing force ever reaches the ligaments.
• Restore forward bend with knee-to-wall calf stretching and ankle joint mobilisation. A stiff ankle changes how you land and pushes the foot onto its outside edge.
• Landing drills onto a folded mat or other compliant surface, so the ankle has rehearsed an uneven landing before somebody's shoe puts one under it at the net.
