An ankle sprain is a stretch or tear of the ligaments on the outer side of the ankle, usually from rolling the foot inward. Most are treated successfully with early, functional rehabilitation, and the old approach of long immobilization has largely been replaced by guided motion and strengthening.
The problem to watch for is chronic instability, when the ankle keeps turning or giving way after the initial injury heals. That is what tips a simple sprain toward needing a brace program or, occasionally, surgery, and it is also a reason to look for injuries a sprain can hide.
Symptoms
Common findings include:
- Pain, swelling, and bruising on the outer ankle after rolling it
- Difficulty bearing weight early on
- A sense of the ankle giving way or turning easily afterward
- Recurrent sprains with progressively less force
What a sprain can hide
Persistent pain after an ankle sprain deserves a closer look, because a sprain can accompany or be mistaken for a fracture, a cartilage lesion of the ankle (OCD), or a tendon injury on the outer ankle. Sorting these out is part of the evaluation when symptoms do not settle.
For an acute sprain, Dr. Lee favors functional rehabilitation, early protected motion, balance and strength training, and a graded return to activity, which recovers faster and more completely than prolonged immobilization.
When the ankle remains unstable despite a genuine rehabilitation and bracing program, surgery repairs or reconstructs the torn outer ligaments to restore stability. Persistent pain prompts a search for an associated cartilage or tendon problem that may need its own treatment.
Non-surgical treatment
Most sprains, and many unstable ankles, respond to:
- Early functional rehabilitation rather than long immobilization
- Balance (proprioception) and strength training
- A brace during return to sport for unstable ankles
- A graded return to cutting and pivoting activity
Surgical treatment
For chronic instability that persists despite a genuine rehabilitation and bracing program, the torn outer ligaments are repaired or reconstructed to restore stability. Any associated cartilage or tendon problem is addressed at the same time.
Recovery timeline
Recovery emphasizes functional rehabilitation:
- Weeks 0 to 2Protected weight-bearing and early motion. Control swelling. Begin balance work as comfort allows.
- Weeks 2 to 6Progressive strengthening and balance training, then a graded return to running and cutting.
- After surgeryA brace early, then progressive strengthening and a graded return to sport over the following months.
What patients commonly misunderstand
Two things to rethink:
- Rest-only is not the best plan. Functional rehabilitation, early guided motion, balance, and strength work, recovers an ankle sprain faster and more completely than prolonged immobilization.
- A sprain that will not settle deserves a second look. Persistent pain after a sprain can mean an associated fracture, cartilage lesion, or tendon injury that a sprain can hide. That is worth evaluating rather than assuming it is just a slow sprain.
