Keith Feder, M.D.
Dr. Feder is a Board Certified Orthopedic Surgeon. A past Chairman of the Department of Orthopedic Surgery at Centinela Hospital and a past chief of Sports Medicine at the UCLA-Harbor Orthopedic Residency Program he is also one of the founders of the West Coast Sports Medicine Foundation. He currently serves as the Medical Director of the West Coast Center for Orthopedic Surgery and Sports Medicine. Dr. Feder is a Clinical Assistant Professor- UCLA School of Medicine, the Director of the Cartilage Restoration Center and the Medical Director of the Team to Win Sports Medicine program. Due to his sports medicine expertise, Dr. Feder is a member of the NFHS (National Federation of High Schools) and the CIF State safety committee. The Governor of the State of California appointed him as a member of the Board of Trustees of the Health Professions Education Foundation. Dr. Keith S. Feder graduated from the SUNY Downstate Medical School, New York. He also completed an internship and residency in orthopedic surgery at the SUNY Downstate Medical Center. Dr. Feder is a fellowship trained in arthroscopic surgery and sports medicine. He has authored several chapters and peer-reviewed scientific articles in the Orthopedic Surgery publishing. He has also served as an Associate Editor of Foot and Ankle International, the official publication of the American Orthopedic Society for Foot and Ankle Surgery. Dr. Feder is a member of the American Orthopedic Society for Sports Medicine (AOSSM) and the Arthroscopy Association of North America (AANA). He co-created the Team to Win program, first of its kind in Los Angeles, aimed at providing sports medicine expertise and treatment to the at-risk students and low-income athletes in the surrounding areas. His involvement in collegiate and high school athletics has facilitated first-hand knowledge of sports participation occurrences. His highly-appreciated expertise in sports medicine is the reason sports organizations and professional athletes have named him Chief Orthopedic Consultant. Currently, he serves L.A. Southwest College, the Nike Real Run Professional Basketball League, National Hockey League Players Association (NHLPA), the Los Angeles Rugby Club, the USA Weightlifting, the Cal State University Dominguez Hills, the DEW-NBC Action Tour, and the L.A. Harbor College. Dr. Feder attended the 1996 Summer Olympics (Beach Volleyball) and the 2000 Summer Olympics (Olympic Weight Lifting) as a Team Physician. He also served the Long Beach Ice Dogs IHL Hockey Team as Medical Director/Team Physician and Chief Orthopedic Consultant (for 7 years), the L.A. Triathlon and the Association of Volleyball Professionals (AVP) for 10 years.

Prophylactic Ankle Brace Use in High School Volleyball Players: a Prospective Study.
The purpose of this study was to determine the effect of prophylactic ankle bracing on the incidence of ankle injuries in a high school population of interscholastic volleyball players followed prospectively for one season.
Mode-locked Picosecond Pulse Generation from an Octave-spanning Supercontinuum.
We generate mode-locked picosecond pulses near 1110 nm by spectrally slicing and reamplifying an octave-spanning supercontinuum source pumped at 1550 nm. The 1110 nm pulses are near transform-limited, with 1.7 ps duration over their 1.2 nm bandwidth, and exhibit high interpulse coherence. Both the supercontinuum source and the pulse synthesis system are implemented completely in fiber. The versatile source construction suggests that pulse synthesis from sliced supercontinuum may be a useful technique across the 1000 - 2000 nm wavelength range. http://www.vitals.com/doctors/Dr_Keith_Feder/credentials#ixzz2eoRSnTVf Doctor Reviews and Ratings Follow us: @Vitals on Twitter | Vitals on Facebook
Grating Phase Matching Beyond a Continuum Edge.
We show that fiber Bragg gratings can extend an optical continuum to spectral regions where continuum generation is very weak. Highly nonlinear fibers with Bragg grating resonances at 700, 750, and 800 nm were pumped with 70 fs pulses at 1580 nm and exhibited enhancement peaks up to 25 dB above the extremely weak continuum at these wavelengths, normally more than 40 dB below the average power in the continuum. We show that the grating peaks may be computed by treating the continuum pulse as an undepleted pump and including the grating dispersion as a phase-matching term.
Fiber-laser Frequency Combs with Subhertz Relative Linewidths.
We investigate the comb linewidths of self-referenced, fiber-laser-based frequency combs by measuring the heterodyne beat signal between two independent frequency combs that are phase locked to a common cw optical reference. We demonstrate that the optical comb lines can exhibit instrument-limited, subhertz relative linewidths across the comb spectra from 1200 to 1720 nm with a residual integrated optical phase jitter of approximately 1 rad in a 60 mHz to 500 kHz bandwidth. The projected relative pulse timing jitter is approximately 1 fs. This performance approaches that of Ti:sapphire frequency combs.
Outcome of Osteochondral Autograft Transplantation for Type-v Cystic Osteochondral Lesions of the Talus.
The treatment of osteochondral lesions of the talus has evolved with the development of improved imaging and arthroscopic techniques. However, the outcome of treatment for large cystic type-V lesions is poor, using conventional grafting, debridement or microfracture techniques. This retrospective study examined the outcomes of 50 patients with a cystic talar defect who were treated with arthroscopically harvested, cored osteochondral graft taken from the ipsilateral knee. Of the 50 patients, 45 (90%) had a mean good to excellent score of 80.3 (52 to 90) in the Karlsson-Peterson Ankle Score, at a mean follow-up of 36 months (24 to 83). A malleolar osteotomy for exposure was needed in 26 patients and there were no malleolar mal- or nonunions. One patient had symptoms at the donor site three months after surgery; these resolved after arthroscopic release of scar tissue. This technique is demanding with or without a malleolar osteotomy, but if properly performed has a high likelihood of success.
