What OAK Orthopedics does

OAK Orthopedics is a regional orthopedic care provider operating as a division of Illinois Bone & Joint Institute (IBJI), one of the largest independent physician-owned orthopedic practices in Illinois. Founded in 1945 and headquartered in Bradley, Illinois (with its main campus in Bourbonnais), the practice delivers comprehensive musculoskeletal care across 10 Illinois locations spanning Bourbonnais, Frankfort, Tinley Park, and Watseka. Its service portfolio covers sports medicine, joint replacement, spine care, orthopedic trauma, pain management, pediatric orthopedics, podiatry, rheumatology, hand and upper-extremity care, foot and ankle care, and physical and occupational therapy, supported by in-house advanced imaging (3T and 1.5T MRI, extremity CT), the OAK Surgery Center ambulatory surgery facility, OrthoAccess walk-in immediate care clinics, and the Health Performance Institute (HPI) wellness and sports-performance division.

The underlying technology stack centers on advanced orthopedic imaging and surgical equipment — including 3T wide-bore and 1.5T open-bore MRI systems, ACR-accredited MRI sites, the ROSA Knee robotic-assisted surgical platform, and the Persona IQ smart knee implant — overlaid on Epic's MyChart patient portal for scheduling, telehealth, records, and billing. OAK is a wholly owned division of IBJI (100+ physicians), with hospital affiliations to Ascension Saint Joseph, Riverside Medical Center, Silver Cross, Palos Community, and Iroquois Memorial enabling surgical and inpatient continuity.

The business model is fee-for-service professional services revenue billed through insurance reimbursement (with separate billing streams for IBJI clinical services and PatientOps for rehabilitation), plus same-day self-pay demand from OrthoAccess urgent care. Go-to-market is hybrid: direct-to-consumer via MyChart self-scheduling, walk-in OrthoAccess, and 17-language community outreach, combined with enterprise-style referral capture from primary care physicians, workers' compensation case managers, athletic organizations, and cross-referrals across the broader IBJI network. Customer base is fragmented individual patient volume — no enterprise or payer concentration — with identifiable priority segments in general orthopedics, sports medicine, and urgent orthopedic care.
