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.

The GOAT (Gold-standard Orthopaedic Advanced Treatment) procedure is an advanced combined shoulder surgery that spans structural repair and biological regeneration in a single operation. Developed by the shoulder specialists at London Cartilage Clinic, this procedure is designed for complex shoulder conditions where conventional single-technique surgery may fall short. The GOAT procedure is currently available exclusively at London Cartilage Clinic in the UK.

Many shoulder conditions involve damage to more than one structure. A labral tear may coexist with cartilage loss, rotator cuff degeneration, or chronic inflammation. Treating each problem in isolation can leave the underlying biology unsupported.
The GOAT procedure was developed to bridge the gap between structural surgery and regenerative medicine. Rather than choosing one or the other, suitable patients receive both.
The GOAT procedure is the result of years of clinical experience in shoulder surgery and biological treatment. It is offered exclusively at London Cartilage Clinic, where our team has developed the surgical protocol and rehabilitation pathway.
Not every shoulder condition requires the GOAT procedure. Our assessment process determines whether this combined approach is appropriate or whether a simpler treatment will achieve the same result.

You may have more options than you think
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.
Protect what you have. Slow degeneration and manage symptoms.
Fix specific damage. Torn tissue, unstable joints, structural problems.
Rebuild lost tissue. Biological treatments that stimulate new growth.
When other options are exhausted. Joint replacement as a last resort.

GOAT stands for Gold-standard Orthopaedic Advanced Treatment. It refers to a combined surgical approach that addresses both structural shoulder damage and the biological environment needed for tissue regeneration, performed in a single procedure.
The GOAT procedure is suited to patients with complex shoulder pathology where a standard single-technique approach may not be sufficient. This includes patients with combined labral tears, cartilage damage, and rotator cuff degeneration who need both repair and regeneration to achieve a lasting result.
The GOAT procedure was developed by our shoulder specialists and combines proprietary techniques with advanced biological treatments. The specific combination of repair, regeneration, and post-operative protocol is exclusive to our clinic in the UK.
Because the GOAT procedure involves multiple tissue types, rehabilitation is carefully staged. Expect sling use for four to six weeks, progressive movement from week one, and a structured return to activity over four to nine months depending on the complexity of the repair.
Standard shoulder surgery typically addresses one problem at a time, for example repairing a rotator cuff or fixing a labral tear. The GOAT procedure combines structural repair with biological augmentation in a single session, aiming to both fix the damage and enhance the healing environment for a more complete recovery.

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 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.
