Why Does My Ankle Still Hurt After a Sprain?
Ankle sprains happen when the foot twists or rolls, stretching or tearing the ligaments. While ligament damage is often the main issue, the joint’s cartilage can also be affected. Cartilage recovers slowly because it has limited blood flow, so wear within the joint can lead to ongoing pain, swelling, stiffness or a feeling of instability long after the sprain.
What Is ChondroFiller and How Does It Work?
ChondroFiller is a non-surgical collagen injection for the ankle joint. The collagen-based gel is injected into the joint, where it may settle over worn surfaces, adding a protective layer that helps cushion the joint and reduce grinding. The procedure is minimally invasive and usually done under local anaesthetic.
Its gel can absorb load and adapt to the forces inside a joint (Weizel et al., 2020). Because it is collagen-based, it has biological potential, but it is best understood as a supportive, joint-preserving injection — not a guaranteed repair, cure or reversal of arthritis.
Why Timely Assessment Matters
Persistent ankle pain that does not settle is worth assessing, often with imaging such as an MRI, so the right approach can be chosen. Left unaddressed, joint wear can progress, so a timely, personalised plan is important.
Expert Care at London Cartilage Clinic
The London Cartilage Clinic is a leading centre for non-surgical joint care, led by Professor Paul Lee. The clinic combines thorough assessment with personalised, supportive care and options such as the ChondroFiller injection, with realistic expectations.
Conclusion
Persistent ankle pain after a sprain may be linked to wear within the joint that standard treatments have not addressed. A non-surgical collagen injection such as ChondroFiller may help support the joint for some people. For individual medical advice, please consult a qualified healthcare professional.

Frequently Asked Questions
- Besides the ligaments, ongoing pain can be linked to wear within the joint, which recovers slowly. Assessment and imaging help identify the cause and whether a non-surgical option may help.
- It is a non-surgical collagen injection that may add a protective, cushioning layer over worn joint surfaces. It is not surgery and not a cure for arthritis.
- Because joint wear can progress, an early, individual assessment helps choose the right approach and set realistic expectations.
- A focus on non-surgical, joint-preserving care, with thorough assessment and realistic guidance.
- Through a thorough assessment, a tailored plan and access to non-surgical options such as the ChondroFiller injection, with realistic expectations.
