Hospitals near you,
measured honestly.

Every hospital Medicare reports on, with the rate, the patient count behind it, and how it compares with the national number and with hospitals like it. Nothing ranked that CMS did not compare.

What the public data can answer

No national file reports infection after knee replacement. Here is the closest measure.

CMS publishes a 90-day complication rate after elective hip or knee replacement, and joint and wound infection are among the complications it counts. Since September 2026 it no longer says which hospitals differ from the national rate, so this page shows each rate with its patient count and ranks nothing.

Reading these numbers

Four things every rate here carries.

  1. 01
    Medicare patients onlyThe hip and knee rates come from Medicare fee-for-service claims, mostly patients 65 and older, risk-adjusted by CMS.
  2. 02
    The patient count beside every rateA rate built on 70 patients can move a full point by chance. Read the count before the rate.
  3. 03
    CMS's comparisons, never oursBetter or worse appears only where CMS published it: patient safety and infections this release, not hip and knee outcomes.
  4. 04
    One location per licenseSystems that report several campuses under one certification number appear once, at the main campus.
