Tendonitis from repetitive workplace motions is a compensable injury under Missouri workers' compensation law — but insurers routinely challenge these claims by arguing the condition is personal, degenerative, or unrelated to work. Chris Miller spent years as a government attorney inside the Missouri Division of Workers' Compensation before founding Bur Oak Injury Law. He knows the arguments insurers use and how to defeat them.
If repetitive gripping, lifting, typing, reaching, or sustained awkward posture at work caused or worsened your tendonitis, you may be entitled to medical treatment, temporary disability payments, and a permanent disability award.

Tendonitis presents an inherent challenge in workers' compensation because insurance companies treat it as a personal medical condition first and a work injury second. Their standard playbook is predictable: obtain an independent medical examination (IME) from a physician who concludes the condition is degenerative, age-related, or unrelated to occupational exposure — and then deny the claim. Without legal representation, most injured workers accept that denial without knowing it can be challenged.
Missouri law does not require that work be the only cause of tendonitis — only that it be the prevailing factor under §287.020 RSMo. That means work must contribute more to the condition than all other factors combined. For workers who perform repetitive motions, sustained gripping, prolonged overhead work, or heavy lifting day after day, meeting that standard is achievable — especially with strong medical evidence and experienced legal representation. Similar issues arise in repetitive stress injury claims across Missouri.
Chris Miller's background inside the Missouri Division of Workers' Compensation — the state agency that hears and decides contested claims — means he understands exactly how Administrative Law Judges evaluate these cases. He knows which medical evidence is persuasive, which insurer arguments are weak, and how to build the record that wins. Learn more about Chris's background.
A tendonitis claim that is denied or undervalued leaves the injured worker responsible for ongoing medical care — cortisone injections, physical therapy, potentially surgery — out of pocket. And a permanent disability award that fails to reflect the true functional impairment cannot be revised later. Getting it right the first time matters.
Missouri workers' compensation provides a range of benefits for tendonitis when the injury is causally connected to work. The specific benefits depend on the severity of the condition, whether surgery is required, and the degree of permanent functional impairment to the affected body part.
All reasonable and necessary medical care is covered, including orthopedic evaluation, imaging, physical therapy, cortisone injections, surgical repair, and post-operative rehabilitation — at no cost to the injured worker when the claim is approved. See: medical treatment benefits.
If tendonitis prevents you from working while you recover, you are entitled to two-thirds of your average weekly wage (subject to Missouri's statutory maximum) until you reach maximum medical improvement. These payments continue even if surgery is required. See: workers' comp benefits overview.
Missouri §287.190 RSMo assigns scheduled member values to different body parts — the shoulder at 232 weeks, elbow at 220 weeks, wrist at 175 weeks, knee at 155 weeks, and ankle at 125 weeks. Your permanent disability award is calculated as a percentage of those weeks based on the degree of functional impairment.
When tendonitis results in permanent work restrictions that prevent you from returning to your prior occupation, Missouri workers' comp may cover vocational retraining costs and wage loss during the retraining period, helping you transition to work within your physical limitations.

Tendonitis develops in workers across a wide range of industries — anywhere that jobs require repetitive motion, sustained force, or prolonged awkward posture. Chris represents injured workers throughout Boone, Cole, Callaway, Cooper, Howard, and surrounding counties in central Missouri.
Common occupations where work-related tendonitis occurs include healthcare workers who perform repetitive patient transfers and documentation; construction workers who use power tools and perform overhead framing; manufacturing and assembly line workers who perform the same gripping and pressing motions thousands of times per shift; warehouse and distribution workers who lift and sort under time pressure; agricultural workers who operate machinery and perform repetitive harvesting tasks; and office workers whose typing and mouse use leads to wrist and elbow tendonitis over time. The injury does not require a single traumatic event — cumulative repetitive trauma is fully compensable under Missouri law when work is the prevailing factor.
Missouri workers' compensation is governed by Chapter 287 of the Revised Statutes of Missouri. For tendonitis and other repetitive trauma injuries, the most important provision is §287.020 RSMo, which establishes the prevailing factor standard: the occupational activity must be the primary cause of the medical condition, contributing more than all other factors — including age, lifestyle, and pre-existing conditions — combined. This is a higher standard than "substantial contributing cause," but it remains achievable for workers with documented repetitive job demands and consistent medical evidence.
The statute of limitations for filing a workers' compensation claim is generally two years from the date of injury under §287.430 RSMo, or two years from the last payment of compensation, whichever is later. For repetitive trauma, Missouri courts recognize a discovery rule — the clock begins when the worker knew or reasonably should have known that the condition was work-related. You must also give written notice to your employer within 30 days of the injury under §287.420 RSMo. Failure to provide timely notice can bar your claim unless an exception applies, such as employer actual knowledge of the injury or no demonstrated prejudice from the delay.
Permanent disability awards for tendonitis are calculated under the scheduled member system in §287.190 RSMo. Each body part is assigned a maximum number of compensation weeks — the shoulder at 232 weeks, the elbow at 220 weeks, the wrist at 175 weeks, the knee at 155 weeks, and the ankle at 125 weeks. The actual award equals the injured worker's weekly compensation rate multiplied by the number of weeks representing the impairment rating. Disputes over the impairment rating — frequently driven by conflicting IME opinions — are among the most common litigation issues in tendonitis cases, and having an attorney who understands how ALJs evaluate competing medical opinions is critical to the outcome.
If you have been diagnosed with work-related tendonitis — including Achilles tendonitis, patellar tendonitis, rotator cuff tendonitis, lateral or medial epicondylitis (tennis or golfer's elbow), or de Quervain's tenosynovitis — the steps you take immediately after the diagnosis directly affect your ability to recover workers' compensation benefits. Report the injury in writing to your employer within 30 days under §287.420 RSMo. Make sure the report identifies the repetitive work activities you believe caused the condition and the specific body part affected. Keep a copy of everything. Seek medical treatment through your employer's designated or authorized treating physician, and follow through with all recommended care. Gaps in treatment are used by insurers to argue the injury is not serious or not work-related.
Insurance companies and employers frequently argue that tendonitis is simply a pre-existing degenerative condition that work did not cause. Missouri law does not require that work be the sole cause — only the prevailing factor. If MRI or ultrasound findings show degenerative changes, that does not end the inquiry. The question is whether the work exposure — the repetitive motion, sustained loading, or awkward posture — caused the clinical presentation to worsen or become symptomatic to a degree that constitutes a compensable disability. Missouri courts and the Missouri Division of Workers' Compensation have recognized that aggravation of a pre-existing condition by occupational activity is fully compensable. This same principle applies to related conditions like trigger finger, carpal tunnel syndrome, and rotator cuff injuries — all of which commonly arise alongside tendonitis in repetitive-work claims. Independent medical examinations from physicians who regularly work with occupational injuries — and who understand the biomechanical demands of specific jobs — are often the decisive factor in these disputes.
