Detection Is Just the Beginning
The same bilateral knee radiographs, read two ways — a conventional report beside a RheumaView™ structured radiographic report.
Why this is a foundational, representative case
This case sits at the entry tier of the complexity ladder: a single study date, a single modality (radiographs), and one paired region (both knees). It is “representative” rather than maximal — there is no prior for interval comparison, no DEXA, and no cross-modality fusion. What it shows is the architecture on a clean foundational example: per-compartment structural read, separation of a post-traumatic pattern from age-related primary osteoarthritis, quantified left-right asymmetry, and explicit data-needs.

An 84-year-old woman was referred to rheumatology for management of presumed “arthritis,” with progressive pain and deformity following prior trauma and surgery.
What a typical report says
FINDINGS
Right knee: Postsurgical changes are present, with a plate and multiple screws fixating the proximal tibia. The hardware appears intact without definite evidence of fracture or loosening. There is deformity of the proximal tibia. Degenerative changes are noted with joint space narrowing, osteophyte formation, and subchondral sclerosis. No acute fracture or dislocation. No joint effusion identified. Soft tissues are unremarkable.
Left knee: No fracture or dislocation. Mild to moderate degenerative changes with joint space narrowing and marginal osteophytes. No significant joint effusion. No radiopaque foreign body. Soft tissues are unremarkable.
IMPRESSION
- Postsurgical changes of the right knee with plate-and-screw fixation of the proximal tibia, intact. Associated osseous deformity.
- Degenerative changes of the right knee.
- Mild to moderate degenerative changes of the left knee.
- No acute fracture or dislocation.

RheumaView™ structured radiographic report
Same dataset, three rendering depths — depth selectable, structure preserved.
FINDINGS
Right knee: Chronic healed fracture deformity of the proximal tibia/tibial plateau with lateral plate-and-screw fixation. Hardware is intact without visible breakage or definite perihardware lucency to suggest loosening on the provided projections. There is chronic deformity and irregularity of the lateral tibial plateau articular surface with persistent joint line incongruity/step-off.
The lateral tibiofemoral compartment demonstrates near-complete joint space loss with marked subchondral sclerosis and marginal osteophytes, consistent with severe lateral-predominant post-traumatic osteoarthritis. The medial tibiofemoral compartment shows mild to moderate joint space narrowing with lesser osteophyte formation and mild subchondral sclerosis. Mild patellofemoral degenerative change is present without advanced patellofemoral collapse.
No acute fracture, dislocation, or focal destructive osseous lesion is identified. Small joint effusion cannot be excluded on the lateral view.
Left knee: Mild medial tibiofemoral joint space narrowing with small marginal osteophytes, compatible with mild medial-predominant osteoarthritis. Lateral tibiofemoral joint space is preserved. Patellofemoral compartment is relatively preserved without significant degenerative narrowing. No acute fracture, dislocation, or focal destructive osseous lesion is identified. Small posterior ossicle is present, compatible with a fabella.
Bone quality: Generalized decreased mineralization of the visualized osseous structures, compatible with osteopenic change.
COMPARISON
No comparison studies available.
IMPRESSION
- Bilateral knees with markedly asymmetric degenerative pattern, dominated by severe right lateral-predominant post-traumatic osteoarthritis in the setting of chronic healed proximal tibial/tibial plateau fracture deformity and intact lateral fixation hardware.
- Additional mild to moderate right medial and mild right patellofemoral degenerative change.
- Mild left medial-predominant osteoarthritis with preservation of the left lateral and largely preserved left patellofemoral compartments.
- No acute osseous abnormality identified on the current study.
- Structural severity is disproportionately advanced in the right knee relative to age alone because of chronic post-traumatic articular remodeling; left-sided changes are within expected late-life mild degenerative range.
- Confidence: high for severe right lateral compartment post-traumatic degenerative change and hardware integrity; moderate for small effusion assessment and osteopenic appearance.
EMR SUMMARY
Pattern: markedly asymmetric bilateral knee osteoarthritis, severe on the right and mild on the left; right knee is lateral-predominant and post-traumatic in distribution. Progression: no prior knee radiographs available for interval comparison. Inflammatory features: no radiographic erosive inflammatory arthropathy identified. DISH: not applicable on this examination. Fracture: chronic healed proximal tibial/tibial plateau fracture deformity with residual articular incongruity and intact fixation hardware.

| Parameter | Right knee | Left knee |
|---|---|---|
| Age-expected degenerative burden at 84 years | Exceeded | Mildly within / slightly above expected late-life range |
| Structural burden percentile (XR-only estimate) | Greater than 95th percentile for age-matched degenerative burden because of major post-traumatic distortion | Approximately 60th-75th percentile |
| Pattern attribution | Age alone insufficient to explain severity;trauma-dominant structural acceleration | Age-compatible mild medialOA |

| Compartment | Left burden | Right burden | Symmetry index | Asymmetry class | Dominant side |
|---|---|---|---|---|---|
| Medial tibiofemoral | 1.1 | 1.8 | 0.61 | Mild-moderate asymmetry | Right |

|---|---|
| Global bilateral knee symmetry class | Low symmetry |
| Dominance pattern | Right-dominant structural burden |
| Asymmetry driver | Right lateral tibiofemoral collapse plus post-traumatic plateau remodeling |
| Secondary asymmetry | Right medial compartment |

6. DEXA-Radiograph Correlation Summary
6A. Availability table
| Field | Status |
|---|---|
| DEXA dataset | Not attached |
| BADA | Not directly computable |
| Delta BMDnorm | Not computable |
| DRI | Not directly computable |
| Cross-modal fusion | Not activated |
| Proxy-only XR bone-quality modeling | Activated |
6B. XR-proxy bone-health estimates (research-only; moderate uncertainty)
| Proxy metric | Estimate | Interpretation |
|---|---|---|
| Radiographic bone-quality deviation | approximately 0.44-0.52 | Mild-moderate deviation from robust bone appearance |
| Mineralization integrity proxy | approximately 0.58-0.64 | Borderline / mildly impaired XR-only proxy range |
| Composite bone-integrity proxy | approximately 0.56-0.62 | Borderline-to-at-risk XR-only estimate |
| Proxy uncertainty | Moderate | Knee radiographs only; no direct densitometry |

6C. Cross-modal narrative summary
- Current images show probable generalized osteopenic background, but the dataset is insufficient for true densitometric quantification.
- Structural damage concentration in the right knee is driven predominantly by post-traumatic articular remodeling and compartment overload, not by diffuse bone-loss pattern alone.
- If DEXA is later attached, the current study is suitable as a structural baseline for subsequent densitometric-structural concordance analysis.

- Secondary structural event: mild-moderate right medial degenerative involvement.
- Contralateral state: mild left medial OA, otherwise relatively preserved left knee.
- Bone-health context: probable osteopenic background, but no direct densitometric quantification available.
- Composite research profile: high-burden, asymmetry-dominant, load-concentrated unilateral advanced OA geometry with positive structural surgery anchor and suppressed true temporal / drift computations because no prior is available.
- Best showcase layers activated here: quantitative knee scoring, compartmental burden matrix, bilateral symmetry analytics, XR-proxy bone-health modeling, composite burden / stability metrics, biomechanics / cartilage-load analytics, visual heat surrogate, and QA-integrity registry-style completeness.

How case complexity scales
Single date · one modality · structural read on a clean baseline.
Multiple timepoints · interval deltas, drift vectors and temporal stability become computable.
More than one modality (e.g. XR + DEXA / MRI / US) · cross-modal fusion and densitometric-structural concordance.
Each tier contributes and compounds structural context; tiers describe scope of input, not interpretive quality.
