Michael R. Lenihan, MD, a board-certified orthopedic sports medicine surgeon in eastern Chula Vista, founded Synergy Orthopedic Specialists, Inc.—now a twelve-physician group—and serves as its president from the Lane Avenue office in the 91914 zip code. His fellowship training at the Kerlan-Jobe Orthopedic Clinic for Sports Medicine included attending to athletes from the Los Angeles Lakers, Dodgers, Rams, Kings, and the PGA Tour, a background that shapes the arthroscopic shoulder and knee reconstruction techniques he applies to referrals from primary care physicians such as Mohammed Elsayed, MD at Oxford Care. He graduated at the top of his class from the University of Southern California School of Medicine in 1986 and completed his orthopedic residency at LA County/USC Medical Center before finishing the Kerlan-Jobe sports fellowship in 1992. As Founding Member and Medical Director of Otay Lakes Surgery Center in Chula Vista, he built an ambulatory surgical facility dedicated to outpatient arthroscopic procedures, reducing post-operative hospital stays for ACL reconstruction, meniscal repair, and rotator cuff surgery. Acute sports injuries requiring same-day orthopedic evaluation frequently arrive through the triage pipeline at Marque Urgent Care when fracture reduction or joint stabilization exceeds urgent-care scope. Highest-complexity procedures include all-arthroscopic anterior cruciate ligament reconstruction with hamstring or patellar tendon autograft and reverse total shoulder arthroplasty for irreparable rotator cuff tears.
