Standardized Image-Based Arthroscopic Technique for Hip Synovial Chondromatosis: Long-Term Patient Outcomes.
Article in Orthopaedic surgery, 2026. 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
objectiveArthroscopic surgery is recommended for the treatment of hip synovial chondromatosis, as it allows patients to resume daily activities quickly and requires only a short rehabilitation period. Despite its advantages, there is currently no standardized protocol for arthroscopic hip synovectomy, and complete removal of intra-articular loose bodies remains challenging. The objective of this study is to evaluate long-term clinical outcomes of arthroscopic treatment for hip synovial chondromatosis using a standardized protocol based on clock-face-guided, imaging-based lesion localization.
methodsA consecutive cohort of patients undergoing arthroscopic treatment and diagnosed with synovial chondromatosis between June 2016 and July 2019 was included in the study. All patients underwent preoperative imaging-guided localization of loose bodies followed by arthroscopic removal performed by a single surgeon, with a minimum postoperative follow-up of 30 months. Preoperative and postoperative assessments included standard radiographs (x-ray), three-dimensional computed tomography (3D-CT), magnetic resonance imaging (MRI), intraoperative arthroscopic images, visual analog scale (VAS) for pain, range of motion (ROM), modified Harris Hip Score (mHHS), and International Hip Outcome Tool (iHOT-12). The percentage of patients achieving the minimal clinically important difference (MCID) was calculated to summarize and compare differences in clinical outcomes.
resultsSeventeen patients were enrolled, with a mean postoperative follow-up duration of 71 months. No major complications were observed. Patients achieved weight-bearing ambulation at a mean of 7 days postoperatively and were discharged at a median of 2.5 days (range: 1-3 days). PROs demonstrated significant improvements: VAS for pain decreased from 7.6 to 2.1, mHHS increased from 54.6 preoperatively to 89.4 postoperatively, and iHOT-12 improved from 38.1 to 75.2 (all p < 0.001). At long-term follow-up, all patients met MCID thresholds for both mHHS and iHOT-12 scores.
conclusionArthroscopic treatment using a standardized protocol can result in favorable long-term clinical outcomes.
