DOC Clinical Decision Support

No storage: Age, scores, and clinical inputs are not written to disk and are not saved to a database.
Session only: Data exists in server memory for the duration of the analysis, then is discarded. Refreshing or closing the browser clears it.
No EHR link: This tool does not connect to hospital records, PACS, or your EMR.
Patient ID optional: Leave blank or use a de-identified code (e.g. “Demo-1”) — never enter names or national IDs.

Optional usage analytics below is off by default and never includes clinical values (no age, WOMAC, BMI, etc.).

Enter Patient Data

Enter patient information to analyze surgical risk and expected outcomes. Required: Age, Sex, BMI, at least one KL grade ≥1. Pain scores are optional but improve accuracy.

Quick demo:

Patient ID (Optional): Not required. Do not enter names or hospital MRN.

Age (30-85):

Sex:

BMI (15-50):

Pain Scores (Optional - improves accuracy): Enter pain scores to improve prediction accuracy, or leave blank to skip.

Skip pain scores (predictions will be less precise)

Right Knee WOMAC Score (0-96): Higher score = more symptoms

Left Knee WOMAC Score (0-96): Higher score = more symptoms

Right Knee VAS Pain (0-10):

VAS Pain at Rest (0-10): Rate pain on a scale of 0 (no pain) to 10 (worst pain imaginable)

VAS Pain During Walking (0-10): Rate pain on a scale of 0 (no pain) to 10 (worst pain imaginable)

NRS Model Active: Predictions will be in NRS points (0-10 scale improvement)

Left Knee VAS Pain (0-10):

VAS Pain at Rest (0-10): Rate pain on a scale of 0 (no pain) to 10 (worst pain imaginable)

VAS Pain During Walking (0-10): Rate pain on a scale of 0 (no pain) to 10 (worst pain imaginable)

Right Knee KL Grade (0-4):

Left Knee KL Grade (0-4):

Knee under discussion (optional): For counseling display only; does not change model weights.

Counseling factors (optional)

Literature-based flags only — does not change model predictions or conservative treatment numbers.

Fibromyalgia (diagnosed or suspected):

Widespread / multisite pain:

High pain worry / catastrophizing:

Depression or persistently low mood:

Active smoker:

Knee pain > 3 years:

Family History (Optional):

Walking Distance (Optional): Time (in minutes) to walk 0.4 kilometers. Typical range: 2-10 minutes.
This field is optional but may improve prediction accuracy.

Previous TKR on Other Knee (Optional): Note: Has the patient had total knee replacement on the opposite knee? Patients who already had TKR on one knee are more likely to eventually need TKR on the other knee.
This field is collected for future use and is not currently used in predictions.

TKR Outcome (Optional):

Model choices (risk + outcome) are set in the Clinical intelligence suite above.

Clinical inputs are processed once and not retained on our servers.

Step 1: Basic Information

Quick demo:

Patient ID (Optional):

Sex:

Age (30-85):

BMI (15-50):

Model configuration

Post-TKR outcome

TKR risk model — choose model

Tree uncertainty band SHAP (≤5 rows)

Step 2: Pain Assessment

Pain Scores (Optional - improves accuracy): Model works without pain scores but predictions may be less precise

Standard symptom assessment (0-96) VAS Pain Scale (0-10) None (skip pain scores)

Step 3: Assessment Details

Right Knee Symptom Score (0-96): Higher score = more symptoms

Left Knee Symptom Score (0-96): Higher score = more symptoms

Right Knee VAS Pain (0-10):

VAS Pain at Rest (0-10):

VAS Pain During Walking (0-10):

Estimated symptom score: -- (average of both scores)

Left Knee VAS Pain (0-10):

VAS Pain at Rest (0-10):
