12/4/2014: I was invited to give a Presidential guest lecture in April 2015 at Arthrocopy Association of North America. So I had to get recent photograph.
This is the requested Bio related to the lecture.
Dr. Johnson was one of the pioneers in arthroscopic surgery. He was probably the first in the USA to perform arthroscopy of the temporal mandibular joint, the shoulder, the elbow, the wrist, the hip and ankle in the 1970’s. He performed perhaps the first arthroscopic repair for shoulder instability in August 1982.
He is holder of more than 60 US patents, most related to arthroscopic surgery and tissue engineering. The most notable was perhaps the motorized instrumentation for arthroscopic surgery. 4,203,444: Surgical Instrument suitable for closed surgery such as of the knee (arthroscopy) 5/20/1980 and 4,274,414: Surgical Instrument (arthroscopic shaver) 6/23/1981.
He has a long interest in cartilage repair and healing. He may have been the first to promote such by arthroscopic means, the procedure known as Arthroscopic Abrasion Arthroplasty.
Although he concluded his clinical practice in 1995 he continues to do research and publications in the cartilage engineering space. The following two publications are long term follow ups on what previously would not have been expected; repair of articular defects with histological evidence of hyaline cartilage and a clinical benefit. Johnson LL, Delano M, Spector M, Gottschalk A, Pittsley A. The Biological Fate of Autogenous Bone Grafting for Large Volume Osteochondral Defects of the Knee: 13020 years follow-up. Johnson LL, Delano M, Spector M, Gottschalk A, Pittsley A. Long Term Clinical Assessment following Autogenous Bone Grafting for Large Volume Three Dimensional Osteochondral Defects of the Knee. ICRS, May 2009, Miami, FL.
The last several years have been devoted to R & D on phytochemicals and their biological effects. He has been issued US patent 8,263,069 Composition including anthocyanins and anthocyanidins for prevention and or treatment of articular cartilage associated conditions. September 11, 2012. His presentation will review his past experience as well as present more recent research concerning the discovery of osteoarthritic disease modifying reagents and novel broad spectrum antibiotic and wound healing promoting reagents.
He believes there is a new era coming in orthopedics will be in tissue engineering and disease modification based upon phytochemicals. He predicts that this will have a greater impact on orthopedic surgery than that of arthroscopy.
