Johnson v. Brown — Pain and functional loss must be considered in musculoskeletal ratings; mild recurrent knee subluxation warrants the minimum compensable rating

The case emphasized that VA must apply the actual rating criteria as written and explain how the veteran’s symptoms fit the chosen rating level. In Johnson v. Brown, the Court clarified how 38 C.F.R. §§ 4.40 and 4.45 apply to musculoskeletal rating claims and distinguished diagnostic codes based on limitation of motion from those based on instability or subluxation.

The veteran appealed ratings involving residuals of a pelvic stress fracture and recurrent subluxation of the left knee. For the pelvic condition, the Board denied a higher rating under Diagnostic Codes 5294 and 5295 without adequately addressing painful motion, functional loss, muscle spasm, limitation of motion, and the applicability of §§ 4.40, 4.45, and 4.67.

The Court held that the Board failed to properly analyze whether the veteran’s pain and functional impairment warranted a higher evaluation. The Court emphasized that functional loss due to pain must be adequately addressed and that painful motion can equate to additional limitation of function under DeLuca principles.

However, regarding the knee disability rated under Diagnostic Code 5257 for recurrent subluxation or lateral instability, the Court clarified that §§ 4.40 and 4.45 do not apply because DC 5257 is not predicated on limitation of range of motion.

The Court further found that the Board improperly denied a compensable rating for the knee despite uncontroverted medical evidence diagnosing “mild, recurrent” subluxation. Because the only permissible view of the evidence supported at least a 10% rating under DC 5257, the Court reversed the Board’s denial and ordered the award of a compensable evaluation.

Johnson became a foundational case involving functional loss analysis, painful motion, instability ratings, and the proper application of §§ 4.40 and 4.45 within musculoskeletal claims.

38 C.F.R. §§ 4.40 and 4.45 apply to diagnostic codes based on limitation of motion and functional impairment, but they do not apply to Diagnostic Code 5257 because that code is based on instability and subluxation rather than range of motion.

• Rating analysis must track the text of the diagnostic code.
• Reasons and bases are required when selecting a percentage.

Functional loss and painful motion must be analyzed in musculoskeletal claims involving limitation of motion, but instability ratings under DC 5257 are evaluated separately from pain-based range-of-motion analysis. Emphasized that VA must apply the actual rating criteria as written and explain how the veteran’s symptoms fit the chosen rating level.

Johnson v. Brown is one of the most important orthopedic rating cases because it clarified when §§ 4.40 and 4.45 apply — and when they do not.

The case established an important distinction between:

• diagnostic codes based on limitation of motion and functional loss,
• versus diagnostic codes based on instability or subluxation.

This distinction remains critically important in knee claims because VA often evaluates multiple knee manifestations separately, including:

• instability,
• limitation of flexion,
• limitation of extension,
• arthritis,
• painful motion,
• and meniscal conditions.

Johnson also strongly reinforces that VA cannot deny ratings when uncontroverted medical evidence directly satisfies schedular criteria. The Court’s reversal of the Board’s denial is especially important because outright reversals remain relatively uncommon in veterans law.

The case additionally reinforces that painful motion and functional loss analysis under DeLuca must be meaningfully addressed when the applicable diagnostic code involves motion-based impairment.

The VA frequently misapplies §§ 4.40 and 4.45 by either failing to consider painful motion in limitation-of-motion claims or improperly attempting to apply pain analysis to instability ratings under DC 5257. VA also commonly ignores uncontroverted favorable evidence satisfying schedular criteria or provides conclusory reasons for rejecting favorable findings without adequate explanation.

• VA cites evidence generally but never ties it to the criteria actually governing the disability.
• VA often states a conclusion without applying the controlling rule from this case to the actual facts of the record.

A veteran seeks an increased rating for a knee condition involving both instability and painful motion. A VA examiner documents recurrent instability requiring a brace, while also noting painful flexion, flare-ups, and additional limitation after repetitive use.

The VA denies a higher rating by concluding that pain is already contemplated under the instability diagnostic code: The Board lists symptoms from the record but never explains why they equal 10% instead of 30%.

Under Johnson v. Brown, instability ratings under DC 5257 are separate from painful-motion analysis. VA must independently evaluate instability under DC 5257 while also separately considering painful motion and functional loss under the applicable limitation-of-motion diagnostic codes and §§ 4.40 and 4.45.

Johnson is strategically valuable in multiple ways.

First, the case helps clarify the legal framework for knee ratings and other orthopedic disabilities involving multiple manifestations. It is especially important when VA improperly merges instability ratings with painful-motion analysis or misunderstands how separate diagnostic codes operate.

Second, Johnson is highly useful when challenging Board decisions that fail to properly analyze:

• painful motion,
• functional loss,
• flare-ups,
• limitation during use,
• or additional impairment caused by pain.

Third, the case is powerful in situations where favorable medical evidence directly satisfies schedular criteria but VA nevertheless denies the claim without meaningful explanation.

Johnson pairs particularly well with:

• DeLuca v. Brown,
• Mitchell v. Shinseki,
• Burton v. Shinseki,
• Correia v. McDonald,
• and Esteban v. Brown.

Commonly tied to 38 U.S.C. § 1155 and 38 C.F.R. Part 4, including the diagnostic code and functional-loss provisions relevant to the disability.
