Characteristics of medial plica syndrome complicated with cartilage damage.
Article in International orthopaedics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
purposeThis study was designed to evaluate the characteristics of patients with medial plica syndrome and associated cartilage damage.
methodsThe study subjects included 44 patients with 57 knees arthroscopically diagnosed with medial plica syndrome. Subjects were divided into those with severe cartilage damage, defined as International Cartilage Research Society (ICRS) stage 2 or higher, and those with mild cartilage damage, defined as ICRS stage 1 or lower. Local findings, period from onset to surgery, arthroscopic findings, and postoperative results were compared in the two groups.
resultsThe shapes of the medial synovial plica were types C and D of the Sakakibara classification in the severe group, and types A, B, and C in the mild group. Patellar ballottement tended to be more common in the severe than in the mild group (P = 0.059). The duration from onset to surgery was significantly longer in the severe than in the mild group (29.0 vs. 11.6 months, P = 0.043). Postoperative results were significantly better in the mild than in the severe group (P = 0.0017).
conclusionsThe shape of the medial synovial plica and the duration between symptom onset and surgery were associated with cartilage damage. Surgical treatment should be considered when the medial synovial plica covers part of the anterior aspect of the medial femoral condyle or ruptures, or when pain persists over a long period, thus reducing the potential for cartilage damage. LEVEL OF EVIDENCE: Level IV.
