🦵 Knee Osteoarthritis Severity Grading Dataset
đź“š Context
Knee osteoarthritis is characterized by degeneration of the knee’s articular cartilage — the flexible, slippery tissue that cushions joints. This condition often involves changes to subchondral bone and adjacent soft tissues. It is the most common form of arthritis to cause knee pain and is often simply referred to as knee arthritis.
Other, less common forms of arthritis that may also cause knee pain include:
- Rheumatoid arthritis
- Pseudogout
- Reactive arthritis
đź“‚ Content
This dataset includes X-ray images of knees designed for:
- Knee joint detection
- Kellgren-Lawrence (KL) grading
KL Grade Descriptions:
- Grade 0: Healthy knee image
- Grade 1 (Doubtful): Slight joint space narrowing; possible osteophytic lipping
- Grade 2 (Minimal): Definite osteophytes; possible joint space narrowing
- Grade 3 (Moderate): Multiple osteophytes, definite joint space narrowing, mild sclerosis
- Grade 4 (Severe): Large osteophytes, significant joint space narrowing, severe sclerosis
