Our research focuses on analyzing leading-edge biologic techniques that stimulate the body's ability to heal itself. In the past, artificial joint replacement was the primary option for treating debilitating joint disease. Today, patients have the option of regenerative repair which is less invasive, allows for faster healing and restores biologic joint services. Biologic joint services are superior to metal and plastics because they feel more natural in the body and allow for activity levels not possible with artificial joint replacement. Outcome studies and preclinical research conducted by the Foundation support treatments that return patients to healthier, more active, and more productive lives than was previously possible.Education: Physicians and other medical professionals learn leading-edge treatments emanating from the research performed. Worldwide publications and presentations proliferate those results. 1157397 true true false false false false false false false false true false false false false false false false false false false false false true false false false false false true false false false false false true false false true false false false false false false false false true 8 0 true 7 true false false false false false false false 0 false false false false false false false X 5 4 false false false false false false false true true false false true true true false false true false false false CA X Kevin Stone 4155633110 3727 Buchanan Street 310 San Francisco CA 941235410 Kevin R Stone MD Chairman 40.00 0.00 X X 250000 0 0 Mani Vessal Dir Research & Ops 40.00 0.00 223539 0 13692 Simaron Dhillon Research Prgm Mgr 40.00 0.00 106289 0 0 Mark Bailey Director 3.00 0.00 X 0 0 0 Jennifer Brinkley Director 3.00 0.00 X 0 0 0 Tim Strickler Director 3.00 0.00 X 0 0 0 Greg Widroe Director 3.00 0.00 X 0 0 0 579828 13692 3 false true false CO State University 2002 Campus Delivery Fort Collins CO 80523 Programs 137539 Community Counselling Service LLC 527 Madison Ave 5th Floor New York NY 10022 Fundraising Consultant 145000 2 10000 1076615 223192 1086615 Medical Studies 74900 74900 74900 17540 17540 0 0 0 0 0 0 0 0 1179055 74900 17540 0 0 0 0 487231 412462 74769 0 286715 251258 35457 0 21313 18042 3271 48357 40936 7421 0 15413 15413 62905 62905 0 145000 145000 0 0 3124 3124 0 0 0 33090 28127 1654 3309 0 0 104271 103674 232 365 0 0 2699 2699 2485 2485 Research 268622 268622 Recruiting 50199 20552 29647 SRF Promotion & Education 15852 15852 Dues & Memberships 13573 11919 1654 21261 6505 13157 1599 1582110 1157397 123875 300838 782061 454269 243123 291261 0 440828 310000 0 0 0 0 0 9429 3827 5639 5602 87925 0 0 0 0 1471651 1149057 22809 115416 22809 115416 X 1448842 1033641 1448842 1033641 1471651 1149057 -403055 -1471 -10675 X false false false X 804579 1820206 1502306 1243816 1086615 6457522 0 0 804579 1820206 1502306 1243816 1086615 6457522 1857841 4599681 148 736 30147 38962 17540 87533 0 41616 13872 543 1868 57899 6602954 0.69660 0.67710 X RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED RESTRICTED 9429 3827 5602 5602 X X X X X X X false Community Counselling Svc 527 Madison Ave 5th Fl New York NY 10022 Fundraising Consult. false 145000 145000 false false false false false false false false false Kevin R Stone MD Chairman 250000 250000 Mani Vessal Dir Research & Ops 223539 13692 237231 The Stone Clinic See Note Below 33090 Leased Office Space false The Stone Clinic See Note Below 30000 Leased Employees false Schedule L, Part V Supplemental Information The Stone Clinic reimbursed The Stone Research Foundation for Sports Medicine and Arthritis $30,000 for imaging fees to the Clinic.
