Knee Condition

Knee conditions often lead to secondary conditions in other joints due to altered gait and weight distribution.

4 known secondary conditions

Secondary Conditions

The following conditions may be claimed as secondary to Knee Condition:

Opposite Knee Condition

DC: 5260/5261 Max Rating: 60%
Caused By Established Link

Medical Connection

Favoring one knee puts excessive stress on the contralateral knee, accelerating wear and degenerative changes.

Evidence Tips

  • Imaging showing degeneration in both knees
  • Gait analysis documentation
  • Medical opinion on compensatory stress

Hip Condition

DC: 5252 Max Rating: 90%
Caused By Established Link

Medical Connection

Abnormal gait from knee problems alters hip mechanics, causing pain and accelerated degeneration.

Evidence Tips

  • Imaging of hips
  • Documentation of gait abnormality
  • Orthopedic opinion on biomechanical relationship

Back Condition

DC: 5237/5242 Max Rating: 100%
Caused By Established Link

Medical Connection

Altered gait and posture from knee problems places abnormal stress on the lumbar spine.

Evidence Tips

  • Spine imaging
  • Documentation of onset after knee injury
  • Medical opinion on compensatory spinal stress

Depression

DC: 9434 Max Rating: 100%
Caused By Established Link

Medical Connection

Chronic pain and loss of mobility from knee conditions commonly leads to depression.

Evidence Tips

  • Mental health evaluation
  • Documentation of functional limitations
  • Impact on quality of life

Tips for Filing Secondary Claims

  • Get a nexus letter: A medical opinion specifically stating your secondary condition is "at least as likely as not" caused by or aggravated by your primary condition is crucial.
  • Document the timeline: Show when your secondary condition developed relative to your primary condition. Earlier development strengthens the connection.
  • Include research: Medical studies showing the connection between conditions can support your claim. Your doctor can reference these in their nexus letter.
  • Be specific on VA Form 21-526EZ: When describing your condition, explicitly state it is "secondary to [your primary condition]" to ensure proper processing.
