Successful Conservative Treatment of an Acute Arterial Occlusion After Total Knee Arthroplasty: Report of 2 Cases and Review of the Literature.
Review in The American journal of case reports, 2022. 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 Acute arterial occlusion after total knee arthroplasty (TKA) is a rare but occasionally limb-threatening complication. Successful outcomes of surgical treatment for acute arterial occlusion after TKA have been frequently reported in the literature; however, few reports have described conservative treatment. This case report describes the successful conservative treatment of popliteal artery occlusion after TKA. CASE REPORT We report 2 cases of popliteal artery occlusion after TKA that were managed with conservative treatment. In Case 1, a 68-year-old woman presented with a weak dorsalis pedis pulse in the foot and weakness to dorsiflexion of the toe on the operative side immediately after TKA. The operative lower extremity arterial ultrasonography and computed tomography angiography demonstrated the popliteal artery occlusion. In Case 2, a 79-year-old woman presented a cold right foot and lack of popliteal and dorsalis pedis pulse in the operated extremity immediately after TKA, and Doppler ultrasound did not reveal a flow for the dorsalis pedis artery. In both patients, urgent angiographies showed popliteal artery occlusion, and blood flow was observable in the anterior tibial, peroneal, and foot arteries collateral perfusion. Thus, conservative treatments were chosen, and anticoagulant and vasodilator therapies were undergone in both patients. At 6 months after surgery, they were able to walk without intermittent claudication. CONCLUSIONS Conservative treatment can be a good option for popliteal artery occlusion after TKA in cases of rich collateral circulation.
