Key features of Illinois's system:
- ✓ Percentage-of-person disability system (no scheduled loss)
- ✓ No cap on PPD weeks for non-scheduled injuries
- ✓ Petitioner can choose treating physician
Illinois Workers' Compensation Commission (IWCC) administers a system notable for its high impairment benefit multipliers — permanent disability is calculated as a percentage-of-person disability, with payments at 60% of average weekly wage for the applicable number of weeks. Illinois has no maximum number of weeks for non-scheduled injuries, which can result in very high PPD awards for significant impairments. Attorney contingency fees are capped at 20% of disputed amounts.

Knee injuries rank among the most common occupational injuries for workers who kneel, squat, climb, or operate heavy equipment. The most prevalent diagnoses are ACL tears, meniscus tears, and patellofemoral syndrome. Most states treat the knee as a "scheduled" body part — meaning your permanent disability benefit is calculated based on a fixed number of weeks tied to impairment rating, regardless of wage loss. New York allows up to 288 weeks and New Jersey up to 315 weeks for total knee loss. Arthroscopic surgery is routine for meniscus repairs, while ACL reconstruction requires months of rehabilitation and often results in accelerated arthritis, which itself qualifies as an ongoing compensable condition in many states.

- ✓ RICE protocol (Rest, Ice, Compression, Elevation)
