1 · What the graph read from it

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.

2 · The registry

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

backgroundThe application of continuous passive motion (CPM) after anterior cruciate ligament reconstruction (ACLR) was popularized in the 1990s, but advancements in the understanding of ACLR rehabilitation have made the application of CPM controversial. Many sports medicine fellowship-trained surgeons report using CPM machines postoperatively. PURPOSE: To determine the efficacy of CPM use for recovery after ACLR with respect to knee range of motion (ROM), knee swelling, postoperative pain, and postoperative complications. STUDY

designSystematic review; Level of evidence, 3.

methodsThe PubMed (MEDLINE), EMBASE, Cochrane, Cumulative Index of Nursing, and Allied Health Literature databases were searched from inception to January 1, 2020, for studies with evidence levels 1 to 3 on the use of CPM for ACLR rehabilitation. Included studies were those that comparatively evaluated postoperative outcomes after ACLR between at least 2 groups of patients, with 1 having received CPM rehabilitation and the other not having received CPM.

resultsA total of 12 studies from 1989 to 2019 met the inclusion criteria. These studies included 808 patients who underwent ACLR. There was no evidence of CPM improving knee stability, final postoperative ROM, or subjective pain scores. Additionally, CPM did not lead to decreased muscle atrophy or improved International Knee Documentation Committee scores. Regarding pain medication intake during postoperative hospitalization, 2 studies found that the CPM group used less pain medication, 1 study found the CPM group used more pain medication, and 1 study found that there was no difference between the 2 groups. Complications varied widely, with 2 of 12 studies reporting complications that required a return to the operating room.

conclusionA clinical benefit of postoperative CPM use after ACLR was not identified in this review. While our systematic review identified a number of studies that suggest CPM use may be associated with lower usage of pain medication in hospitalized patients, this cannot be confirmed without further investigation with standardized CPM protocols and larger sample sizes. Routine CPM use after ACLR was not supported by this systematic review.
