Methodology

How KneeEd reads your sessions

Your plan adapts based on what you tell us and what your sessions show. Here is what our system does, what it does not do, and where a real clinician should always be the judge. Plain language, real architecture, no marketing.

What KneeEd does

  • Reads the survey you complete and produces a multi-week movement plan with phases tuned to your category: Recovery, Performance, Prevention, or Maintenance.
  • Adjusts your plan after each session based on the pain and difficulty you report. A plan that was the right shape last week may not be the right shape today.
  • Generates short coaching prompts before, during, and after sessions, voiced for where you are in the program.
  • Catches contraindications before they reach you, via a deterministic safety stage that the AI cannot bypass.

What KneeEd is not

  • Not a diagnosis. We do not tell you what is wrong with your body.
  • Not a prescription. Plans are educational, adherence-support tools, not medical treatment.
  • Not a substitute for your physical therapist, physician, or surgeon. Bring your plan to them. We help you stay on track between visits.
  • Not an emergency service. If pain is severe, sudden, or paired with new symptoms, stop and seek qualified help.

The pipeline

Eight stages, one plan

Your plan passes through eight stages from intake to delivery. Some stages use AI; some are deterministic rules. Safety is always deterministic.

  1. 01

    Profile extraction

    AI

    Reads your survey and produces a structured profile: region, condition, severity, surgical status, activity goals.

    Stage 1 of 8
  2. 02

    Protocol matching

    Rule

    Maps your profile to a clinical protocol template: evidence-informed, condition-specific, with phase progression rules.

    Stage 2 of 8
  3. 03

    Exercise pool

    Rule

    Builds a candidate pool of exercises filtered by region, phase, difficulty, and contraindications for your condition.

    Stage 3 of 8
  4. 04

    Exercise selection

    AI

    Selects and customizes specific exercises from the pool to fit your phase, frequency, and progression rate.

    Stage 4 of 8
  5. 05

    Safety validation

    Rule

    The non-negotiable stage. Removes anything the model picked that is not in the phase-appropriate pool built in stage 03, and substitutes from the same category. AI cannot override.

    Stage 5 of 8
  6. 05b

    Quality evaluation

    AI

    Scores plan quality on completeness, safety surface, and patient relevance. Non-critical: fails open with logged warnings.

    Stage 6 of 8
  7. 06

    Nutrition guidance

    Rule

    Generates condition-aware nutrition recommendations: recovery-supportive macros, anti-inflammatory considerations.

    Stage 7 of 8
  8. 07

    Product recommendations

    Rule

    Surfaces orthopedic supports, braces, or recovery tools relevant to your condition. Non-critical, can be skipped.

    Stage 8 of 8

Safety

Where the safety checking actually happens

Every plan passes through a deterministic safety validator before it becomes active. No plan can be saved without one. The filtering by condition and phase happens earlier, when we build the candidate pool your plan is drawn from, and the validator then removes anything the model selected that is not in that pool and substitutes an alternative from the same category. The AI cannot override it.

Being specific about the limits, because they matter more than the mechanism. Our condition-specific rules currently cover 31 conditions, and 111 of our 600 exercises carry contraindication tags. Where we have no rule for your condition, the plan is still built from a phase-appropriate pool but no condition-specific filtering has been applied. Sport and training plans are filtered by pain and impact level only, not by contraindication rules. We do not yet gate on surgical status.

For a plan you adopt from another member, KneeEd has no intake for that plan, so it applies a conservative safety floor instead and does not claim to have checked the plan against your condition.

Clinical advisors

A clinical advisory board, forming.

We are forming a clinical advisory board to review every protocol template before release. These seats are open. We announce each advisor here once their credentials are verified and they have signed the public disclosure agreement.

Orthopedic rehab

Seat in formation

Seeking: Licensed DPT, orthopedic specialty

Will review the knee and hip protocols across the Recovery and Performance categories.

Sports medicine

Seat in formation

Seeking: Board-certified sports medicine MD

Will review contraindication coverage and surgical-status gating in the safety validator.

Rehabilitation science

Seat in formation

Seeking: PT with a PhD in rehabilitation science

Will review the adjustment algorithm and outcome measurement.

Athletic training

Seat in formation

Seeking: Certified athletic trainer, ATC and CSCS

Will review the Prevention and Maintenance categories.

Regulatory posture

Where we sit, by design

KneeEd is an educational and adherence-support product, not a medical device and not a covered entity. Our posture is built so that the day a partner asks for a Business Associate Agreement or a state attorney general asks how we handle consumer health data, the answer is already in production.

HIPAA

PHI-shaped data handling

Patient data is treated as PHI. RLS-enforced per-user isolation on every authenticated query. The admin client is reserved for service operations and writes an audit-log entry for every mutation it performs.

In production

MHMDA + state privacy

Consumer health data, by the letter

Data Subject Rights are handled within the 45-day window required by Washington's MHMDA. AI plan generation requires a per-event consent record, separate from Terms of Service acceptance, and re-consent fires on material model changes.

In production

FDA posture

Education and adherence support

KneeEd is educational and adherence-support software. Not a medical device, not a diagnostic, not a treatment. SafetyBanner and HealthDisclaimer surfaces ship on every plan and we do not make therapeutic claims anywhere in our copy.

In production

Security posture

What enterprise diligence sees

The controls below are either in production or in active execution. We label each one honestly so a clinic admin or an investor can audit our claims against reality.

  1. 01

    SOC 2 Type 1

    Audit underway

    Type 1 attestation is in progress with our audit partner. Type 2 follows the standard observation window once Type 1 closes. Current status, scoping, and target attestation date available under NDA.

    In progress
  2. 02

    Enterprise contracts

    BAA-ready posture

    Our data handling, vendor list, and incident-response procedures are structured so that signing a Business Associate Agreement with a partner clinic or health system is a paperwork step, not a re-architecture project. No BAAs are in place today, including with our model vendors.

    In progress
  3. 03

    Penetration testing

    Quarterly third-party reviews

    We engage a third-party firm for penetration testing on a quarterly cadence. Findings are tracked to closure with severity-tiered SLAs and the most recent report summary is shareable with prospective enterprise customers under NDA.

    In progress
  4. 04

    Data portability

    FHIR R4 export

    A clinician-readable JSON export is available to every member at /api/account/export and is audit-logged on every request. A FHIR R4 bundle (Patient, CarePlan, Observation, Procedure) is available to Plan Club Pro members at /api/fhir/Patient/[userId], for import into clinical systems. The underlying record is never behind the membership, only the clinical packaging of it.

    In development

Per-plan transparency

See how your plan was built

Every plan you generate carries a pipeline trace: which stages ran AI, which ran deterministic rules, which substitutions the safety stage made. Visible from your plan detail page.

Methodology changelog

What changed and when

  1. v2026.05.2

    2026-05-06

    Added a public platform stats strip, a clinical advisory board surface, and explicit regulatory and security posture sections so investors, partner clinicians, and reporters see real numbers and named controls before the prose.

  2. v2026.05.1

    2026-05-04

    Disclosed that we are pursuing Business Associate Agreements with our AI vendors, and added a Minors and Family Accounts section so a parent, coach, or athletic trainer can manage athletes ages 13-17 with full responsibility for consents and data.

  3. v2026.05.0

    2026-05-03

    First public methodology release. KneeEd's plan engine now describes itself in plain language: what it reads, what it suggests, and where a real clinician should always be the judge.
