Kevin Robert Stone, MD (born June 4, 1955) is an American Orthopedic surgeon , who gespecialiseerd in sports medicine and injuries of the knee, shoulder, and ankle joints. He has lectured and been honored Internationally as an authority on cartilage and meniscal growth, replacement , and repair. Stone Berninahaus for his development of the paste grafting chirurgische technique in 1991, combined with meniscus replacement , welke are biology joint replacement procedures for the regeneration of the knee joint.  He has taught synthesis techniques to Surgeons in the US  and worldwide.
He is the founder and chairman of the Stone Research Foundation for Sports Medicine and Arthritis, a center dat conducts research in advanced chirurgische techniques and tissue regeneration in San Francisco , California . This research has led to advancements in cartilage replacement and regeneration, cruciate ligament repair and reconstruction, and techniques to preventable osteoarthritic Degeneration. He holds morethan 50 US patents on healthcare Inventions. 
Stone was born in Providence , Rhode Island in 1955. He was educated at the Moses Brown School and Harvard College , class of 1977, where he led the Eliot House Crew to row at The Henley Regatta and polo played will. If a cum laude biology graduate, he enrolled in the University of North Carolina School of Medicine graduating in 1981. He was Trained at Harvard’s Beth Israel Hospital in internal medicine from 1981-82, dan in general surgery at Stanford University Medical Center from 1982- 83, and lastly in orthopedic surgery at The Harvard Combined Orthopaedic Residency 1983-1986. He took under a fellowship in research at the Hospital for Special Surgery in New York under Steven Arnoczky, DVM and in knee surgery in Lake Tahoe under Richard Steadman, MD, from 1986 -1987.
Stone founded The Stone Clinic , combine himself, an orthopedic surgeon, with a team of nurses, physical Therapists, imaging specialists, and patient Coordinators, in 1988 to focus on caring for injured athletes and people are experiencing arthritis pain. The clinical practice goal of rehabilitating all patients to a level hogere dan ze ze ulcers voordat ulcers injured set the tone. Surgical procedures ulcers subjected to rigorous analysis outcomes with the results Reported in peer reviewed journals. The chirurgische techniques port leg taught to Surgeons around the world, through lectures and videos. 
Stone is a physician for The Marin Ballet and The Smuin Ballet. He has served as a physician for the US Ski Team ,  the US Pro Ski Tour, the Honda Ski Tour, the 48 Straight Ski Tour, the Old Blues Rugby Club , the Lawrence Pech Dance Company, the modern pentathlon at the US Olympic Festival, and for the United States Olympic Training Center.
Stone Initiated his research career in high-altitude physiology under the direction of Ross McFarland, at the Harvard School of Public Health . Working with his associate Dr. Spengler, Stone searched for a high-altitude environment in a city and published the first paper on carbon monoxide in hockey rinks noting the effect of carbon monoxide on the hockey players’ visual ACUITY was similar to therein or hypoxia at altitude.
While in internship, Stone published one of the first case reports on the formation of a liver cancer in patients who had hepatitis C . His subsequent research residency Returned to the area or tissue oxygenation, which focuses on ligament oxygen tension using a self-designed oximeter .
In 1984, Stone, at the Encouragement of his mentor Dr. Steadman, turned his focus to Replacing the meniscus cartilage in the knee joint. After two years of research to under stand the biomechanics and biology of the meniscus, Dr. Stone concluded dat if he Could not replace the meniscus, Possibly have Could re-grow it. With this approach he entered his Fellowship in research under the direction of Dr. Arnoczky and proceeded to design the first collagen meniscus regeneration template.
While a clinical fellow in Lake Tahoe, Stone Initiated research at the Letterman Army Institute of Research in collaboration with Bill Rodkey, DVM , to test the collagen template verschillende animal models for meniscus, ligament, articular cartilage and intervertebral disc repair. These trials ulcers subsequently published and led to verschillende research awards waaronder the Albert vibrating board Young Investigator’s Award from the International Knee Society and the Cabaud Award in 1990 from the American Orthopaedic Society for Sports Medicine.  The FDA not approved the first human clinical trial of the collagen meniscus scaffold welke was carried out at The Stone Clinic from 1991 to 1994. Recently 15-year follow-ups on patients synthesis revealed Continuing successful outcomes. The US Food and Drug Administration showing US approval for a collagen meniscus implant (CMI) device designed by Stone in 2008.
Stone turned his attention to complete meniscus replacement with a biological implant (Rather dan re-growing the meniscus) in 1994. He published one of the first techniques for arthroscopic meniscus replacement in 1991 and conducted the first long-term study of meniscus replacement in knee joint arthritis welke was published in 2006. The replacement of the meniscus permits the arthritic patient to harbor most innovative pain relief and knee joint function as well as delay or Avoid the time for artificial joint replacement. In a 2 to 7 year follow-up study, 89.4% of meniscus transplantation patients ulcers successful, maintaining shown significant signs of improvement in pain, activity, and functioneren.  A study on the outcomes of meniscus transplantation in active patients with severe cartilage damage appears that the procedure Provided significant improvements in pain and function levels for an average of 8.6 years with the Majority of patients Achieving hun goal of participation in sporting activities. 
Articular cartilage research
In addition under to meniscus replacement, Stone focused on articular cartilage regeneration for the arthritic knee. His design of a “paste graft” technique with custom instrumentation was promoted by the DePuy Orthotec orthopedic company . The paste graft technique 2-12 year results in later published in 2006 Revealing 85% of the patients obtained improvement in pain and function scores.  A study on the efficacy of the paste graft procedure for patients with osteochondritis dissecans Showed dat patients ulcers loveable to benefit from improvements in pain, activity, and function levels for an average of 7 years after the procedure, with some benefitting up to 13 years. 
Biologic joint replacement
The combination or meniscus replacement and articular cartilage grafting led to Stone’s pursuit of biology knee replacement, a technique to ‘fully replace the damaged cartilage in the knee with natural tissue. This program is Underway at The Stone Clinic and of includes a voice cell with shell graft approach to Replacing the articular cartilage surface of the knee.
Allison Gannet, a World Cup freeskier Champion, had had seven previous knee surgeries voordat maintaining a biological joint replacement, with Stone as re surgeon. This procedure included the articular cartilage paste grafting procedure, and following, Gannet Reported being pain free for the first time in 8 years. 
Aperion Biologics, Inc.
Xenograft ligament cartilage, bone, and tendon transplantation.
FDA Approved ACL Replacement Study 2003 – PRESENT
CE Mark Issued April 2014.
The company’s experience with collagen scaffolds sourced from bovine Achilles tendons led im to focus on other animal tissues That might be useful for orthopedic reconstruction. In 1996 he Initiated a research program to determine if the carbohydrates dat cause rejection or animal tissues Could Safely be removed without damaging the tissues. His research led to im the New York Blood Center where a technique for Removing similar carbohydrates were developed for blood. Dr. Stone indicated with and collaborated with the leading Immunologist in the field Prof. Uri Galili in order to transfer the blood technique to orthopedic tissues. Their work led to multiple patents, animal trials and subsequently, a human clinical trial or a porcine bone-patellar tendon-bone graft for reconstructing the anterior cruciate ligament (ACL) of the knee joint. In the chirurgische procedure, the proteins on the transplant ligament therein mention anything trigger rejection from the recipient’s body are stripped off prior to transplantation. One recipient of this pig ligament ACL transplant went on to win the Canadian Masters Downhill Skiing Championship, three times.  This work has RECEIVED FDA approval for a wide clinical trial to be conducted in the US

Stone is the founder or co-founder of multiple companies in addition under to his Orthopedic medical practice and research.
- Rain Biologics, a Publicly traded medical device company focused on meniscus regeneration. At rain from 1984-1994, Stone invented the first collagen meniscus implant, a device designed to function as a regeneration template to grow a new meniscus cartilage in human knees. Rain Biologics attracted controversy after the FDA initially rejected Menaflex, a device developed to replace knee cartilage. Rain Biologics enlisted four members of Congress, Whom they ‘had made significant campaign contributions to, to influence the evaluation process. The FDA-then fast-tracked and not approved the product on Despite serious concerns from the scientific community.  rain Biologics was Accused of “unduly” influencing federal agencies,  and the FDA admitted it capitulated to political pressure for approving Menaflex,  a device it had to post deemed unsafe Because Of zijn failure rate. 
- CrossCart Inc., now Aperion Biologics Inc. a venture capital funded medical device company xenotransplantation. At CrossCart Stone led a team with Uri Galili and Tom Turek to dévelop a technique for Removing the antigens from pig tissues so dat ze ‘may be-used in humans. The first xenograft device for reconstruction or ruptured anterior cruciate ligaments (ACLs) RECEIVED FDA approval for human clinical trials. If successful, this technology ‘may permit animal tissues to be-used in humans without the need for immunosuppression. 
- Joint Juice, Inc., now Premier Nutrition Inc. a San Francisco-based nutraceutical beverage company. Stone’s invention It or Joint Juice was a response to his patient’s statements therein glucosamine helped Them en hun animals but therein the pills ulcers too large to accomplish regularly. Joint Juice is the first beverage with a full day’s dose of glucosamine , proven to pain-reducing, act as an anti-inflammatory, and aid in cartilage repair without side effects. Juice products are available nationwide at major warehouse clubs, grocery stores and drugstores.  
- Rescue Reel, LLC, a San Francisco-based supplier of personal rescue devices. Stone shared the horror of watching people leap to hun deaths on 9/11 and fact represented compelled to relieve the problem of building egress. He worked with an engineering team to design Rescue Reel, the first personal rescue device therein personen kan use to escape from buildings up to 100 stories. The device is pure chance to gain wide application zowel for commercial buildings, residential buildings, oil rigs, ships, military applications and fire rescue.
