Orthopedic Specialists of San Diego is a fellowship-trained orthopedic surgery practice in Allied Gardens at 5555 Reservoir Dr #104, San Diego, CA 92120, across from the UC San Diego East Campus. Board-certified surgeons Mark Jacobson, Steven Allsing, James Bates, and Michael Mousselli cover total hip replacement, total knee replacement, partial knee replacement, shoulder replacement, rotator cuff repair, hand surgery, foot and ankle reconstruction, and spine surgery. Allsing is one of a select group of San Diego surgeons with advanced training in MAKO robotic-assisted surgery, performing all primary joint replacements with robotic guidance calibrated to patient-specific CT imaging, and the practice shares surgical referral networks with San Diego Sports Medicine & Family Health Center in Grantville for post-operative sports-medicine rehabilitation. He graduated from the University of California San Diego School of Medicine and has twice served as chairman of the Department of Orthopedic Surgery at both Sharp Grossmont and Alvarado Hospitals. Bates completed his orthopedic surgery residency at the Hospital for Special Surgery at Cornell University Medical Center in New York and holds the rank of Captain in the United States Navy Reserve, with over 30 years of combined active-duty and reserve service as a Naval Flight Surgeon and Diving Medical Officer. The practice performs computer-assisted navigation surgery and minimally invasive joint replacement techniques, with onsite digital X-ray imaging that eliminates the need for a separate radiology appointment. Hospital affiliations include Sharp Grossmont Hospital, Sharp Coronado Hospital, and Alvarado Hospital Medical Center, giving the practice operating-room access across multiple facilities. The group also maintains a second office at Coronado Physicians Medical Center for scheduled appointments. The Reservoir Drive medical corridor near SDSU anchors orthopedic, spine, and pain-management services for Allied Gardens, Grantville, and Del Cerro residents in the 92120 ZIP. Complex spinal cases that require neurosurgical co-management draw referrals across the Allied Gardens district to the Spine and Brain Institute of San Diego on the Grantville side of the 8 freeway. Bates holds current certifications from the American Board of Orthopedic Surgery and has presented internationally on robotic-assisted hip replacement.
