Average Settlement for Knee Injury in Illinois

2026-06-15 · Injury Benefit Calc Research Team

Introduction

If you have suffered a knee injury at work in Illinois, you are probably wondering what your workers’ comp claim is worth. The honest answer: it depends on the severity of your injury, the strength of medical evidence, the Illinois workers’ comp formula, and several other factors. This article provides realistic 2026 settlement ranges for knee injuries in Illinois based on industry data and state-specific rules.

How Illinois Calculates Workers’ Comp Benefits

Illinois uses a 66.67% wage-replacement rate based on your pre-injury average weekly wage (AWW). For 2026 injuries, the Illinois workers’ comp rates are:

• Maximum weekly TTD rate: $1,813
• Minimum weekly TTD rate: $250

The weekly rate is calculated as:

Weekly rate = min($1,813, max($250, 66.67% × AWW))

Higher-wage workers hit the $1,813 cap, while lower-wage workers may be floored at the $250 minimum. The cap is the most important factor for high-earning workers in Illinois.

Typical Settlement Ranges for Knee Injuries in Illinois

Based on 2025-2026 industry data, NCCI reports, and publicly reported settlements, the typical knee workers’ comp settlement in Illinois falls into the following ranges:

Note: These are illustrative ranges for Illinois. Your actual settlement depends on the unique facts of your case.

For Illinois, the state-specific factors that affect the settlement include:

• The 2026 max weekly rate of $1,813 (relatively high compared to other states)
• The 2026 min weekly rate of $250
• The 66.67% wage-replacement rate
• The maximum TTD duration (typically 104 weeks for non- catastrophic injuries)

How Severity Affects the Settlement

The severity of the knee injury is the single most important factor in determining the settlement amount.

Low-severity cases typically involve:

• Mild strain, sprain, or contusion
• Conservative treatment (rest, ice, NSAIDs, physical therapy)
• Recovery in 4-8 weeks
• No permanent impairment rating
• Settlement range: $12,000

Mid-severity cases typically involve:

• Moderate injury (e.g., partial tear, bulging disc)
• Physical therapy for 8-16 weeks
• Possible steroid injections
• Minor permanent impairment (5-15% whole-body)
• Settlement range: $35,000

High-severity cases typically involve:

• Severe injury (e.g., full tear, fracture, surgery required)
• Surgical intervention
• Recovery of 3-12 months
• Significant permanent impairment (15-50% whole-body)
• Possible job retraining or permanent work restrictions
• Settlement range: $85,000

Factors That Affect Your Illinois Settlement

Several factors influence the final settlement amount for knee injuries in Illinois:

1. Impairment rating: The treating physician’s permanent impairment rating (using the AMA Guides 5th Edition) is a major driver of PPD benefits in Illinois.
2. Pre-injury wages: Higher-wage workers receive higher weekly benefits (subject to the Illinois cap of $1,813/week).
3. Age: Older workers may receive higher ratings and longer benefits due to the longer expected duration of disability.
4. Medical evidence: Strong, well-documented medical evidence supports higher settlements.
5. Type of treatment: Surgical cases typically settle for more than conservative-treatment cases.
6. Disputed vs. accepted liability: Disputed claims may settle for less, but settlements avoid trial risk.
7. Attorney representation: Workers with attorneys typically receive higher settlements than workers without attorneys.

Settlement Examples for Knee in Illinois

To illustrate how Illinois-specific factors affect settlements, consider these examples:

Example 1: Mild knee case

• A Illinois worker earning $900/week suffers a mild knee injury
• 12 weeks of TTD at $600/week (66.67% × $900) = $7,200
• Reaches MMI with no permanent impairment
• Settlement: $12,000 (lump-sum for the time and medical expenses)

Example 2: Moderate knee case

• A Illinois worker earning $1,500/week suffers a moderate knee injury requiring surgery
• 26 weeks of TTD at $1,000/week (66.67% × $1,500) = $26,000
• 10% permanent impairment rating
• PPD benefits (10% × state schedule) = $15,000-$20,000
• Settlement: $35,000

Example 3: Severe knee case

• A Illinois worker earning $2,200/week suffers a severe knee injury
• 52 weeks of TTD at $1,467/week (66.67% × $2,200, capped at $1,813) = $76,284
• 30% permanent impairment rating
• PPD benefits (30% × state schedule, capped at $1,813 max rate) = $60,000-$100,000
• Future medical expenses estimated at $30,000-$60,000
• Settlement: $85,000

Negotiating a Settlement in Illinois

Settlement negotiations in Illinois typically begin after the worker reaches MMI and the impairment rating is finalized. The negotiation is between the worker’s attorney and the insurance carrier, with the Illinois workers’ comp agency having final approval authority.

Common settlement structures in Illinois include:

• Compromise and Release (C&R): A lump-sum payment that closes both medical and income benefits for the injury. The worker gives up the right to future medical treatment related to the injury.
• Stipulated Settlement: A negotiated payment for the future income benefits portion only, with medical benefits remaining open. The carrier accepts a reduced amount in exchange for a fixed future obligation.
• Section 32 Waiver (in some states): Similar to C&R with specific statutory requirements.

Never sign a settlement without consulting an attorney — the first offer is rarely the best deal, especially for knee injuries that may require future medical care. The Illinois workers’ comp agency must approve all settlements, and an administrative law judge reviews the settlement to ensure it is in the worker’s interest.

knee in Illinois?

The average knee workers’ comp settlement in Illinois ranges from $12,000 for mild cases to $85,000 for severe cases. The median settlement for moderate cases is approximately $35,000.

claim in Illinois?

Can I get a lump-sum settlement for knee

in Illinois?

In most cases, yes. A lump-sum settlement is called a Compromise and Release (C&R) in Illinois. The lump sum closes your medical and income benefits for the injury in exchange for a one-time payment. Never sign a C&R without consulting an attorney — the first offer is rarely the best deal.

Will my settlement be reduced by attorney fees in

Illinois?

In Illinois, attorney fees in workers’ comp cases are regulated and subject to agency approval. The typical attorney fee is 15-25% of the settlement, depending on the complexity of the case. The fee is taken from the settlement, not from your pocket. Most workers’ comp attorneys offer free initial consultations.

How does the Illinois maximum weekly rate affect

my settlement?

The Illinois maximum weekly rate of $1,813 for 2026 is the cap on weekly TTD and PPD benefits. Workers earning above the equivalent of $2,719/week hit the cap. This means high-wage workers receive a smaller percentage of their pre-injury wage than lower-wage workers, which can affect the settlement amount.
