A surgeon-led clinical system for the decade between "nothing is wrong" and "you need surgery."
Early osteoarthritis, meniscus changes, cartilage thinning, labral wear, shoulder tendinopathy. The imaging shows something, the pain is real, and the surgical pathway is not yet appropriate.
Joint Longevity Program →Achilles, patellar, rotator cuff, lateral epicondyle. Eight weeks, eight months, or two years in. Physical therapy helped partially or not at all.
Tendon Optimization Program →The repair has been done. The tissue is healing. The question is whether the recovery environment is optimized for the best possible outcome.
Post-Op Recovery Program →Most clinicians discussing peptides cannot read your MRI. Most orthopedic surgeons do not have time for the longevity conversation. Chronos is built to hold both — because questions about recovery biology and questions about a joint or tendon are not separate conversations. This is education and clinical judgment, not a product menu.
Dr. Rahman is lead author of a 2026 JAAOS Global review on therapeutic peptides in orthopaedics and presents at the Peptide World Congress and the Cell Surgical Conference. A Longevity Consultation is the structured conversation about what is reasonable for your situation — honest about the science, clear about the regulatory picture, and specific to your goals.
Read the Peptides & Longevity ReviewThe Participation-Preservation System is the clinical framework that shapes everything at Chronos. It is not a brand name for a single procedure. It is a structured approach to three things: assessing the tissue, the mechanical demand, and the participation target; selecting the program that fits the clinical problem; and building reintegration milestones around what the patient is actually trying to do.
The system is what separates a coherent plan from a menu of one-off treatments.
Understand the System
The longevity and regenerative medicine space has grown rapidly, often without orthopedic surgical expertise at the table. Chronos brings that expertise to the conversation.
Dr. Omar Rahman is a board-certified orthopedic surgeon and sports medicine specialist, fellowship-trained at Kerlan-Jobe in Los Angeles. Lead author of a 2026 review in JAAOS Global on therapeutic peptides in orthopedics. Consultant to medical device companies on AI and surgical technology. Peer reviewer for the American Journal of Sports Medicine, the Journal of Shoulder and Elbow Surgery, and the Journal of Orthopedic Experience & Innovation.
Meet Dr. Rahman
Some patients are told they need surgery when they do not. Others delay past the point where it would have been a better answer. The honest decision requires looking at the tissue, the mechanics, and the participation target together.
Read: Do You Need Surgery?The first step at Chronos is an Initial Consultation — a focused clinical evaluation and the welcoming front door to the practice, whatever brought you here. The output is a clear plan.
