Osteoarthritis: AI-Powered Imaging Analysis

AI-powered knee osteoarthritis detection on X-ray and MRI. Assess joint space narrowing, osteophyte formation, cartilage loss, and Kellgren-Lawrence grading. 4 AI models provide parallel analysis of your imaging.

Knee osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage loss, subchondral bone changes, and osteophyte formation. Imaging plays a crucial role in grading severity and monitoring progression. Our AI consortium evaluates both MRI and X-ray studies, providing Kellgren-Lawrence grading on radiographs and detailed Outerbridge cartilage grading on MRI. The multi-model analysis identifies compartmental involvement, subchondral changes, and associated findings like meniscal degeneration and ligament laxity.

Common Symptoms

Gradual onset of knee pain, worse with activity
Morning stiffness lasting less than 30 minutes
Crepitus or grinding sensation during movement
Progressive loss of range of motion
Knee swelling after prolonged activity
Pain going up or down stairs
Visible joint deformity (varus or valgus alignment)

What We Look For on Imaging

Joint space narrowing on weight-bearing radiographs
Marginal osteophyte formation at joint margins
Subchondral sclerosis (increased bone density below cartilage)
Subchondral cyst formation
Cartilage thinning or full-thickness loss on MRI
Bone marrow edema pattern (bone bruise-like changes) on MRI
Meniscal degeneration and extrusion

Frequently Asked Questions

What is Kellgren-Lawrence grading?

Kellgren-Lawrence (KL) is a radiographic grading system for knee OA: Grade 0 (normal), Grade 1 (doubtful narrowing, possible osteophytes), Grade 2 (definite osteophytes, possible narrowing), Grade 3 (moderate osteophytes, definite narrowing, some sclerosis), Grade 4 (large osteophytes, marked narrowing, severe sclerosis, bone deformity). Our AI provides KL grading on knee X-rays.

Is MRI or X-ray better for evaluating knee arthritis?

Both have roles. Weight-bearing X-rays are the standard for grading severity (Kellgren-Lawrence). MRI provides detailed cartilage assessment (Outerbridge grading), detects early changes invisible on X-ray, and shows associated soft tissue findings. Our AI analyzes both modalities when available.
