About Dr. Finn

Practice. Dr. Henry Finn is a board-certified orthopedic surgeon practicing in Chicago, Illinois. The latest annual CMS data records 12 knee replacements. That is #243 in Illinois for knee replacement. A Medicare provider since 2006.

National context. Among 6,612 knee replacement surgeons tracked nationally, 12 procedures is below the national average of 45. Medicare covers part of all joint replacements, so true volume is likely higher.

Local context. Chicago has 41 orthopedic surgeons in the current Medicare data. Comparing volume and procedure mix across them is one way to narrow a shortlist.

Verified Medicare Cases

Estimated 2024 total: 40 – 50 procedures (all insurers)
Medicare fee-for-service share of national volume in 2024: 23% to 28% for knee replacement
How is this estimated?

Medicare Part B fee-for-service claims are one payer stream among several, and the share they represent differs by procedure. In 2024 it was 23% to 28% for knee replacement. Each verified count above is divided by its own procedure's range, and the results are added, to estimate total practice volume across all payers. The verified Medicare count is the definitive, audited figure; this is a range derived from published national volume projections, not a measurement, and an individual practice can sit well outside it: how these ranges are derived, and their sources.

Knee Replacement Recovery Overview

Recovery timelines vary by patient, but here is a general overview of what to expect after knee replacement surgery:

Week 1-2 Walking with assistive device. Knee bending exercises begin immediately. Ice therapy and elevation for swelling control.
Week 3-6 Increased range of motion (target 90 degrees). Walking longer distances. Physical therapy intensifies with strengthening exercises.
Week 7-12 Most patients walk without assistive devices. Resume driving and desk work. Continue PT for strength and flexibility.
Month 4-6 Near-full recovery. Resume most recreational activities. Some swelling and stiffness may persist but continues improving.

Individual recovery varies based on overall health, age, and adherence to physical therapy. View full knee replacement recovery guide and product recommendations

What does the Medicare data for Dr. Finn represent?

The procedure counts shown are based on 2024 Medicare Part B fee-for-service claims data, published by the Centers for Medicare and Medicaid Services (CMS). Medicare fee-for-service is only one payer stream, and the share of national volume it represents differs by procedure. In 2024 the share was 23% to 28% for knee replacement, which puts Dr. Finn's total volume across all insurers at roughly 40 to 50 procedures against the 12 verified here. Those shares are derived from published national volume projections rather than quoted from a single publication, and they are estimates with real uncertainty. The OrthoProcedures methodology page shows the full derivation, the sources, and the limits at orthoprocedures.com/data-methodology.html.

Has Dr. Finn's procedure volume changed over time?

Dr. Finn's Medicare-recorded volume peaked at 82 procedures in 2018 and was 12 in the most recent data. Volume fluctuations can reflect changes in payer mix, practice focus, or Medicare reporting rather than a change in overall surgical activity.
