Fulkerson Osteotomy Effect on Knee Joint Position Sense, Gait Kinematics, and Functional Level.
Article in Orthopaedic journal of sports medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Patellofemoral joint chondral lesions (PFCLs) are one of the most common chronic knee problems in all populations in young adults. Despite their high frequency, there is still no consensus about treatment options. All PFCL grades can be treated with surgery, nonoperative treatment, or both. Purpose/Hypothesis: The purpose of this study was to compare patients with PFCLs who underwent Fulkerson osteotomy surgery followed by physical therapy and rehabilitation with those patients who only received physical therapy and rehabilitation. It was hypothesized that patients who underwent unilateral Fulkerson osteotomy surgery would have superior results compared with patients who only received nonoperative treatment. Study Design: Cohort study; Level of evidence, 3. Methods: This was a prospective study with a case-control design and included 20 patients who underwent Fulkerson osteotomy and 20 patients with PFCL who were managed nonoperatively. The follow-up period was a median of 13.25 months (range, 12.03-14.71 months) for patients who underwent Fulkerson osteotomy and 12.85 months (range, 12-14.37 months) for patients who were treated nonoperatively. Knee joint position sense and gait kinematics were assessed using the DrGoniometer Application and Zebris FDM-T device. The functional level was determined using the single-leg hop test, the single-leg squat test, and the Kujala subjective knee evaluation form. Results: When comparing gait kinematics of the affected sides between patients who underwent Fulkerson osteotomy and those who received nonoperative treatment (physical therapy and rehabilitation only), differences were observed in step length, cadence, stance phase percentage, and swing phase percentage ( Conclusion: Patients who underwent Fulkerson osteotomy had superior gait kinematics, joint position sense at 60° of flexion, and Kujala scores. No significant changes were observed in terms of the joint position sense at 15°, 45°, and 90° of flexion, the single-leg hop test, and the single-leg squat test compared with those who received nonoperative treatment.
