Chronic ankle sprains and ankle instability often result from stretched or torn lateral ligaments and poor neuromuscular control after repeated “rolling” injuries. A proper evaluation looks at swelling, tenderness, range of motion, strength, balance and stability tests—and may include imaging if pain, locking or persistent swelling suggests tendon, cartilage or fracture issues. Most cases improve with a stepwise rehab plan: restore motion, rebuild calf/peroneal strength, progress balance and hopping drills, and use bracing or taping during return to sport. If instability persists after 8–12+ weeks of structured rehab, regenerative options (like PRP) or surgical consultation may be considered. Seek urgent care if the ankle cannot bear weight, has deformity or shows significant bruising or swelling.
Acute ankle sprains are among the most common musculoskeletal injuries we see. An estimated two million sprained ankle incidents occur each year in the U.S.1 Chronic ankle sprains and ankle instability often develop after rolling the ankle inward and experiencing the initial ankle sprain. Stretched, weakened or torn lateral ligaments and poor neuromuscular control after repeated “rolling” injuries contribute to ankle instability. Up to 70% of individuals with prior sprains develop chronic instability.2
Weakened or stretched ligaments typically stem from a previous injury that did not heal properly, leading to Chronic Ankle Instability (CAI). It often results because of incomplete rehabilitation, reduced balance and weak surrounding muscles and ligaments.
Patients commonly describe it as a feeling that the ankle is “giving out.” This cycle continues because initial, unsuccessfully rehabilitated sprains leave the ankle weak. Then subsequent, repeated twisting or rolling injuries lead to:
Imaging may be necessary if pain, locking or persistent swelling suggests tendon, cartilage or fracture issues. Generally, a proper evaluation considers:
Early evaluation after an initial sprain can help to prevent chronic ankle sprains and ankle instability.
Most cases improve with a stepwise rehab plan: restore motion, rebuild calf/peroneal strength, progress balance and hopping drills, and use bracing or taping during return to sport. Ankle stability is improved through progressive strengthening. The patient moves from non-weight-bearing exercises to weight-bearing exercises.
To prevent recurrent sprains, the goal is to:
When dealing with CAI, ankle strengthening follows a progression: going from isometric, non-weight-bearing exercises to dynamic, single-leg, with plyometric movements.
Rehabilitation is designed to progressively add resistance, instability and speed to rebuild both ankle strength and proprioception.
Critical for injury prevention and ankle stability, proprioception is your body’s ability to sense the position and motion of your ankle joint. Proprioception relies on sensory receptors in your muscles, ligaments and tendons to detect changes in terrain, which in turn triggers rapid, reflexive muscle adjustments that help you maintain balance when walking or running.
Key phases of strengthening progression include:
If your chronic ankle sprains and instability persist after 8–12+ weeks of structured rehab, regenerative options or surgical consultation will need to be considered. Surgery is more costly with a longer recovery timeline. Regenerative Medicine options, on the other hand, can trigger unprecedented healing in tissues that experience low blood flow, reducing pain and inflammation and avoiding the need for surgery.
Regenerative Medicine treatments have the ability to transform ankle conditions ranging from chronic lateral ankle instability to ligament and tendon tears, as well as any associated arthritis. Options may include:
Platelet-Rich Plasma (PRP) Injections: Using your own platelets, which are rich in growth factors, PRP is derived from your blood, spun in a centrifuge to concentrate platelets, then injected to enhance and speed healing, reducing pain and inflammation. and triggering your body’s intrinsic healing abilities.
Prolotherapy: This treatment involves the injection of an irritant solution into damaged, weak, or torn ligaments to stimulate your body's natural inflammatory healing response, thereby strengthening your ankle.
Stem Cell Therapy: Utilizing stem cells can help to repair or even regenerate damaged tissue in the ankle, restoring joint function and decreasing pain from more severe or chronic injuries to your ankle. Stem cells can be injected into the site of ankle injury. Stem cells can be sourced from:
These procedures all work to speed healing, reduce pain, and often help to avoid the need for surgery. They can be used together for enhanced results. New options in Regenerative Medicine are continually being developed, and our team stays on top of the latest developments.

Most individuals do not seek care for a one-time ankle sprain, but that is often a mistake. While not every sprained ankle requires immediate medical attention, you should always seek medical care if you cannot walk, if it feels unstable, or if pain and swelling continue to worsen. It is essential to rule out fractures or severe tears and prevent long-term ankle instability from developing.
You actually should seek urgent care if the ankle cannot bear any weight, has deformity or shows significant bruising or swelling.
That will depend on the precise nature of the ankle condition being treated and the treatment method you choose, as well as how your body responds to the treatment.
Generally, with conventional treatment for chronic ankle sprains and instability – utilizing physical therapy, bracing, and exercise – you should experience initial improvements within three to six weeks. Full recovery often requires three to six months. Reduced pain/swelling is often seen within four to six weeks, with return to sports or high-impact activities typically requiring eight to twelve weeks.
If conventional methods are not successful, Regenerative Medicine therapies typically require a phased healing timeline of three to six months with full benefits sometimes continuing to develop for up to a year. Initial improvements are often experienced within weeks.
It is important to find an orthopedic sports medicine specialist who is not only experienced in dealing with ankle injuries and conventional treatment methods, but who is also knowledgeable about emerging Regenerative Medicine therapies.
