Cartilage Repair (Experimental)
Damaged joint cartilage does not heal well on its own. Several repair techniques exist and some are established, but many cell-based and regenerative approaches are still experimental.
Causes & risk factors
- Sports or accident injuries to the joint
- Wear and tear (leading to osteoarthritis)
- Repeated joint stress
- Previous joint injury or surgery
- Joint alignment problems
Common symptoms
- Joint pain, especially with movement
- Swelling after activity
- Catching, locking or giving way of the joint
- Reduced range of movement
- Stiffness
Tests & diagnosis
- Clinical examination
- MRI to assess cartilage
- X-ray to assess the joint
- Arthroscopy (keyhole look inside the joint)
Treatment & management
- Physiotherapy and activity changes for many cases
- Some surgical repair techniques are established for small defects
- Cell-based cartilage repair is used in selected specialist cases
- Many regenerative and stem-cell approaches remain experimental
- Joint replacement for advanced joint damage
When to see a doctor urgently
- Persistent joint pain, swelling or locking
- A joint that gives way or catches
- Before choosing experimental repair — get a specialist opinion
Frequently asked questions
Can cartilage grow back?
Cartilage has a very limited ability to heal itself. Some surgical techniques can repair small areas, but there is no proven way to fully regrow cartilage across a worn joint — despite what some clinics claim.
Are regenerative cartilage treatments proven?
A few cell-based repairs are used in selected specialist cases, but many advertised regenerative treatments are still experimental. A specialist can advise what is appropriate and evidence-based for you.
