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

  1. Strengthening exercises for the affected compartment
  2. Range-of-motion and stretching exercises
  3. 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

QuestionAnswerIs 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

Related Conditions

  • General knee osteoarthritis
  • Meniscal tears

Additional Treatments

Physical therapy and orthotics may provide additional benefit.
