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.
Tennis Elbow
Tennis elbow (lateral epicondylitis) is a painful condition affecting the tendons on the outer elbow. It is caused by repetitive gripping and wrist extension and is one of the most common reasons for elbow pain in adults.

What causes tennis elbow?
The common extensor tendon attaches to the lateral epicondyle (outer bony prominence of the elbow). Repetitive loading causes micro-tears that the tendon cannot repair quickly enough, leading to a cycle of degeneration rather than healing.
- Pain on the outer elbow that radiates down the forearm.
- Weakness in grip, difficulty lifting a kettle or turning a door handle.
- Tenderness directly over the lateral epicondyle.
Treatment options
Treatment follows a structured pathway from conservative measures to biological intervention.
- Eccentric strengthening exercises and load management with physiotherapy.
- PRP injection to stimulate tendon healing at the cellular level.
- mFat therapy for refractory cases that have not responded to first-line treatments.
- Counterforce bracing to offload the tendon during activity.
We focus on treating the underlying tendon pathology rather than simply masking pain, because the goal is lasting resolution, not temporary relief.
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
Do I need to play tennis to get tennis elbow?
No. Tennis elbow is caused by repetitive gripping and wrist extension activities. It is common in office workers, manual labourers, and anyone who performs repetitive forearm movements. Racquet sports are just one of many causes.
How long does tennis elbow last?
Most cases resolve within 6 to 12 months with appropriate treatment. However, some patients develop chronic tendinopathy that persists for longer. Early, targeted treatment can shorten the recovery timeline.
Are steroid injections effective for tennis elbow?
Steroid injections can provide short-term pain relief but evidence suggests they may not improve long-term outcomes and can weaken the tendon with repeated use. At London Cartilage Clinic, we typically favour physiotherapy, PRP, or mFat for sustained improvement.
When is surgery needed for tennis elbow?
Surgery is rarely needed. It is considered only when symptoms persist despite six to twelve months of structured conservative and biological treatment. The procedure involves removing the degenerated portion of the tendon.

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.
