Unicondylar Degenerative Arthritis
What is Unicondylar Degenerative Arthritis?
Unicondylar Degenerative Arthritis is arthritis that affects one compartment of the knee, typically resulting in localized pain and joint degeneration.
- Degeneration in a single compartment of the knee
- Localized pain and stiffness
Overview of the Condition
This condition is often seen in patients with early-stage osteoarthritis confined to either the medial or lateral compartment.
Symptoms
- Pain localized to one side of the knee
- Stiffness and reduced range of motion in the affected compartment
- Swelling in the knee joint
Causes
Often due to uneven joint loading, previous injury, or early degenerative changes confined to one compartment.
Diagnosis
Diagnosis is made with clinical evaluation and confirmed with imaging studies such as X-rays.
Treatment Options
- Conservative management with physical therapy and NSAIDs
- Unicompartmental knee replacement in advanced cases
Conservative Management
Treatment includes activity modification, weight management, and targeted exercises.
Rehabilitation Exercises
- Strengthening exercises for the affected compartment
- Range-of-motion and stretching exercises
- Low-impact aerobic activities
Surgical Options
For severe cases, unicompartmental (partial) knee replacement may be performed.
Anatomy Overview
The knee is divided into medial and lateral compartments; in unicondylar arthritis, only one compartment is affected.
Affected Areas
- Medial or lateral compartment of the knee
- Adjacent subchondral bone and cartilage
Frequently Asked Questions
| Question | Answer |
|---|---|
| Is unicompartmental replacement better than total knee replacement? | It may offer faster recovery with more natural knee kinematics for appropriately selected patients. |
| Can it be managed non-surgically? | Yes, early stages can often be managed with conservative treatments. |
Prevention Strategies
- Maintain a healthy weight
- Engage in regular low-impact exercise
- Avoid excessive stress on one side of the knee
