Your knee hurts after a twist on a loading dock, a fall, or weeks of kneeling on the job. The clinic writes “knee pain.” The employer says there is seated work available. The adjuster asks whether you had knee trouble before.
Those are different questions. A useful record connects the actual work, the medical history, the treatment request, and the duties you can safely perform. “My knee hurts” is the beginning—not the whole explanation.
For workers in Downey, the Gateway Cities, and across Los Angeles County, a new California proposal is a reason to pay attention to that record. It is not a reason to wait for care or assume treatment has been approved.
California proposed a knee-guideline update—not a treatment approval
On September 15, 2026, DWC announced a proposal to update the Medical Treatment Utilization Schedule, or MTUS, by incorporating ACOEM's July 8, 2026 Knee Disorders Guideline into section 9792.23.6. The agency scheduled a public hearing for October 16, 2026, with written comments due that day.
As checked September 22, 2026, this is a proposal. DWC's current MTUS page still lists the knee-guideline order effective September 21, 2020, and the posted current regulation incorporates the December 3, 2019 guideline. The proposed order lists December 1, 2026 for services, but that is a proposed date—not proof of final adoption.
MTUS helps determine the extent and scope of reasonable and necessary treatment. DWC explains that adopted guidelines are presumed correct, with procedures for conditions not covered and for rebutting recommendations using medical evidence. A public rulemaking announcement does not establish that your knee condition is work-related or authorize a particular MRI, injection, brace, therapy program, or surgery.
This article does not compare the clinical recommendations in the old and proposed guidelines. Your treating physician should evaluate your medical needs and the applicable standards. Do not wait for the hearing to report an injury, seek care, or address a claim deadline.
Record the knee, the movement, and the change
Be specific without guessing a diagnosis or reconstructing details you do not remember.
- Which knee? Left, right, or both. If another area also hurts, tell the medical provider rather than assuming it is part of the knee claim.
- What movement or event? Describe the twist, impact, fall, step, lift, kneeling, squatting, climbing, or other task. Include the surface, equipment, and load when relevant and known.
- One incident or repeated work? For a single event, save the date, location, and report. For repeated duties, describe the work period, frequency, breaks, and changes in workload. Label estimates as estimates.
- What changed? Explain when symptoms began, what you could do before, and what became difficult afterward. Describe symptoms in your own words; let a clinician identify their cause.
- Who was told? Keep the injury report, messages, supervisor and witness names, and copies of the DWC-1 claim form with delivery records.
DWC's claim guidance says the employer must give or mail a claim form within one working day of learning of the injury or illness. Keep your completed employee portion and request the employer-completed copy. Reporting symptoms to a clinic is not a substitute for returning the claim form to the employer.
Seek emergency care for an emergency. For changing or worsening symptoms, contact a medical professional promptly; a worksheet cannot assess how urgently you need care.
Do not hide the earlier knee history
Tell the treating physician about prior knee injuries, surgery, symptoms, treatment, and nonwork events. Preserve earlier reports alongside the new records.
The useful comparison is factual: what existed before, what duties you performed, what happened at work, and what changed afterward. An imaging label or an old injury does not by itself resolve all the medical and legal questions in a claim. Nor does pain beginning at work establish every element of coverage.
If the dispute concerns an earlier condition, see our pre-existing injury guide. Avoid trying to settle causation yourself by interpreting an MRI report.
Find out which question is actually disputed
Ask for the written notice—not just “the knee was denied.”
- Work connection or claim scope: Is the administrator disputing that work caused the condition, or whether the knee is included in the claim? Save the acceptance, denial, and medical reports. This is different from deciding whether a particular treatment is medically necessary.
- Treatment authorization: What specific care did the treating physician request? Ask for the RFA, supporting report, submission date, and response. A recommendation in a visit note is not necessarily a completed authorization request.
- Medical necessity: If utilization review denies or modifies treatment on medical-necessity grounds, independent medical review may be the appropriate process. Save the full decision and application materials and obtain prompt help with the applicable deadline. An informal call or request for reconsideration should not be assumed to extend it.
- Scheduling: If care is authorized but no appointment is available, save the authorization, scheduling attempts, cancellations, and next available date. Do not label an appointment delay a UR denial unless that is what the notice says.
DWC's May 14, 2026 clarification identifies the DWC Form RFA as the standard treating-physician request; a narrative equivalent has specific conditions. Our RFA explanation and IMR guide address those separate processes. The proposed knee update does not replace either one.
Compare restrictions with the whole job—not its label
A job described as “seated” may still involve stairs, walking between stations, carrying materials, or getting on and off equipment. A warehouse or delivery title may hide repeated squatting or climbing.
Copy the doctor's restrictions exactly. List the actual demands beside them: standing and walking periods, stairs, kneeling, squatting, lifting, and required movements. Ask the physician to clarify vague limits; do not write your own medical restrictions.
Keep the written offer, schedule, work-status slips, questions and responses, and wage records if hours or earnings change. Do not assume a mismatch automatically establishes wage-benefit eligibility. Get advice before simply quitting or refusing an offer, and seek medical guidance about unsafe or painful tasks. Our modified-duty guide explains the broader comparison.
Bring a focused knee record to the next conversation
Use the companion worksheet to organize the task history, baseline symptoms, reporting, current medical records, exact restrictions, and unanswered treatment question. It is a private organizing aid, not a DWC claim form, RFA, medical opinion, or appeal. Completing it does not file anything or extend a deadline.
Save originals. Request corrections through the provider's process rather than altering a report. Collect worksite records only safely and lawfully; do not take coworkers' or patients' private records.
If the knee is disputed, care is stalled, or the offered job conflicts with restrictions, bring the notices and reports to a consultation with Workers' Compensation Law Group. Call WCLG at (562) 608-8870 for a free consultation about your California workers' compensation questions.
This is general information, not individual legal or medical advice. Benefits and procedures depend on the evidence and claim posture. Contacting WCLG does not create an attorney-client relationship.
