Increased radiographic stifle soft tissue opacity in dogs with patella luxation.
Article in Veterinary surgery : VS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo determine the prevalence of increased radiographic soft tissue opacity in canine stifles with patella luxation in the absence of overt cranial cruciate ligament (CCL) pathology. STUDY
designRetrospective case series. ANIMAL POPULATION: A total of 49 client-owned dogs (57 limbs).
methodsDogs with patella luxation that underwent arthrotomy with CCL evaluation were included. Dogs were excluded if overt pathology of the CCL was noted during orthopedic examination and/or surgical evaluation. Correlation of increased radiographic soft tissue opacity with age, breed, weight, duration of clinical signs, presence of stifle osteoarthritis, muscle atrophy, and luxation grade were evaluated.
resultsIncreased radiographic soft tissue opacity of the stifle was appreciated in 37/57 (65%) stifles. Weight (p = .029) and presence of osteoarthritis (p = .0143) were associated with the presence of increased radiographic soft tissue opacity. For every 1 kg increase in weight there is a 10% increased risk in having this radiographic change. Four of 21 dogs (19%) with long term follow-up were diagnosed with a CCL injury 2, 2.5, 4, and 4.5 years postoperatively. Two of the four dogs (50%) with later CCL injury had increased radiographic soft tissue opacity in the stifle joint when initially presenting for patella luxation.
conclusionIncreased soft tissue opacity of the stifle joint may be found on radiographs of dogs with patella luxation without overt CCL pathology. CLINICAL SIGNIFICANCE/IMPACT: Increased radiographic soft tissue opacity within the stifle joint is not uncommon in dogs with patellar luxation that do not have overt CCL pathology. Increased radiographic soft tissue opacity alone should not infer pathology of the CCL in dogs with patella luxation.
