A twisted knee at work, a fall on the stairs, a T-bone collision that pins a leg against the dash, knee injuries arrive through wildly different accidents but tend to follow a similar claims path once an MRI confirms the damage. This page walks through what an adjuster checks first and how this site's calculator turns your bills into an estimate.
What insurers look at first
Before anything else, an adjuster wants imaging. A knee complaint without an MRI or at least an X-ray reads as soft-tissue soreness that will resolve on its own, regardless of how it actually feels. Once a tear, whether ACL, meniscus, or MCL, is confirmed on film, the conversation changes, because now there's an objective diagnosis instead of a subjective complaint. The next thing checked is whether you followed through on the recommended treatment path; skipping physical therapy or delaying a referral to an orthopedic specialist gives the other side room to argue the injury wasn't serious enough to warrant the claim you're making.
How the math works
| Severity tier | Multiplier | Typical knee injury example |
|---|---|---|
| Moderate | 2.5× | Sprain or strain, resolves with physical therapy |
| This page's default | 3.0× | Knee injury claims generally, per this site's convention |
| Serious | 3.5× | Arthroscopic surgery, meniscus repair |
| Severe | 4.5× | ACL reconstruction, documented lasting instability |
Add your medical bills and lost wages, run the multiplier on the medical figure, and the injury claim calculator totals it for you. Pre-existing arthritis at the same joint is the most common complication insurers raise to push the number down, so a clean prior medical history, if you have one, is worth documenting early.
