The problem with joint care today

The system is built to react.
Not to prevent.

Most people see a surgeon when the damage is already significant. Years of preventable deterioration have happened quietly — in the biology, the muscles, the metabolism — long before the pain becomes undeniable.

🦴
Joint damage starts decades before symptoms
Cartilage loss, muscle atrophy, and metabolic inflammation begin in your 30s and 40s. By the time it hurts, the window for easy prevention has closed.
530M affected globally
🔬
Fragmented care misses the full picture
A scan shows structure. It does not show biology, strength capacity, metabolic health, genetic risk, or recovery function. No single specialist sees all five. Until now.
Biology-first approach
💪
Most joint ageing is modifiable
Strength, sleep, metabolic health, load management, and targeted biological therapies — applied in the right sequence — change the trajectory of a joint over a lifetime.

"I've spent a decade seeing thousands of patients and operating on knees — so I understand the problem from the inside. Working alongside the best physiotherapists, osteopaths, sports medicine doctors, radiologists, and metabolic clinicians, I've built a joined-up, holistic framework that most patients never receive. What used to be available only to elite professional athletes — a complete, coordinated picture of joint health — should be available to everyone. That is what OrthoLongevity™ is."

★★★★★
"Mr Imbuldeniya changed the quality of my life and for that I will be forever grateful. He will try the least invasive option first, he actually listens to your concerns, worries and fears. He is without question in my opinion the best orthopod in the country."

Knee surgery & ongoing management

Bilateral knee pain
★★★★★
"He explained the imaging and diagnosis in a way that I could understand. At the moment I do not need any surgical intervention but if that changes then I would have every confidence that I would be in safe hands."

Important — Medical & Regulatory Information
Wellness assessment — not a medical device or diagnostic service. The OrthoLongevity™ Knee Age assessment is a self-reported wellness questionnaire designed to support healthy lifestyle choices and general joint health awareness. It is classified as a Class I wellness tool and does not constitute a medical diagnosis, clinical assessment, or regulated medical device under UK Medicines and Healthcare products Regulatory Agency (MHRA) guidance or the Medical Devices Regulations 2002 (as amended). It is not regulated by the Care Quality Commission (CQC).

Not a substitute for clinical care. The Knee Age score and associated recommendations are for general informational and educational purposes only. They do not replace a clinical consultation with a qualified healthcare professional. If you have joint pain, injury, swelling, locking, instability, or any other musculoskeletal symptom, you should seek advice from a registered medical practitioner. Do not delay seeking medical advice on the basis of information received through this tool.

Future platform. Features described as 'coming soon' — including AI-powered predictive insights, genomic risk scoring, health portal, and diagnostic integrations — are in development and not currently available. When launched, features involving the analysis of health data or clinical decision support will be subject to appropriate regulatory classification and approval processes, including MHRA Medical Device registration where required.

Clinical services. Face-to-face consultations with Dr Arj Imbuldeniya and the OrthoLongevity™ clinical team are delivered at Lanserhof Mayfair and Cromwell Hospital, both regulated healthcare facilities. These services are separate from this wellness assessment and are subject to full GMC, CQC, and professional regulatory oversight.
