Cartilage Repair

Single-Session Cartilage Repair with STACi
Cartilage repair that once required two operations spanning three to six months is now completed in a single operative session lasting 2.5–4 hours through STACi.
Big Toe Arthritis
Big toe arthritis (hallux rigidus) is one of the most common forms of foot arthritis. It causes pain and progressive stiffness at the base of the big toe, affecting every step you take.

Understanding hallux rigidus
The first MTP joint bears up to 60% of body weight during the push-off phase of walking. When cartilage wears and bone spurs form, this essential movement becomes painful.
- Pain at the top of the big toe joint, particularly when bending the toe upward.
- A visible bony bump on the top of the joint from spur formation.
- Progressive stiffness reducing the ability to walk, run, or wear certain shoes.
Treatment options
- Stiff-soled shoes or carbon fibre plates to limit painful joint motion.
- Injection therapy (steroid, HA, PRP) for pain management.
- mFat biological treatment to support cartilage and reduce inflammation.
- Cheilectomy or fusion for advanced cases that do not respond to conservative care.
The goal is to maintain the joint for as long as possible. Every month of preserved movement is a month of normal walking mechanics.
You may have more options than you think
Most patients have more treatment options than they have been told
At London Cartilage Clinic we follow a structured clinical framework across four areas of treatment. Before recommending a single procedure, we assess which combination of approaches gives you the best outcome.
Preserve
Protect what you have. Slow degeneration and manage symptoms.
Repair
Fix specific damage. Torn tissue, unstable joints, structural problems.
Regenerate
Rebuild lost tissue. Biological treatments that stimulate new growth.
Replace
When other options are exhausted. Joint replacement as a last resort.

Frequently Asked Questions
What is hallux rigidus?
Hallux rigidus is arthritis of the first metatarsophalangeal (MTP) joint at the base of the big toe. It causes the joint to stiffen and lose its normal range of motion, making push-off during walking painful and difficult.
How does big toe arthritis affect walking?
The big toe joint is critical for the toe-off phase of gait. When it stiffens, the foot compensates by altering walking mechanics, which can lead to pain in other parts of the foot, knee, or lower back.
What non-surgical treatments are available?
Options include stiff-soled footwear or carbon fibre insoles to reduce joint stress, steroid or hyaluronic acid injections, PRP, mFat therapy, and physiotherapy. These can provide meaningful relief and delay the need for surgery.
When is surgery needed?
Surgery is considered when pain and stiffness significantly limit walking despite non-surgical treatment. Options include cheilectomy (removing bone spurs to improve movement) and fusion (arthrodesis) for advanced cases. Your specialist will discuss which approach suits your stage of arthritis.

ACL Injury

Does a Partial ACL Tear Always Need Surgery
A partial ACL tear does not always require surgery; the decision hinges on whether the knee remains mechanically stable under load, though approximately 40% of young athletes managed conservatively eventually sustain a complete rupture.

ChondroFiller Hip Injection Cost and Lifetime Joint Preservation
ChondroFiller hip injections cost £6,500–£9,500 and recruit the patient's own cells to repair cartilage; a structured preservation model requires yearly imaging and bi-annual top-up injections.
