No difference in early functional outcomes for mini-midvastus and limited medial parapatellar approaches in navigation-assisted total knee arthroplasty: a prospective randomized clinical trial.

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
Patients desire less pain and faster recovery of range of knee motion after total knee arthroplasty (TKA). While minimal invasive surgery (MIS) TKA appears to meet these needs, concerns exist regarding component malpositioning. Navigation systems can reduce the incidence of component misalignment. The present prospective randomized study compared limited medial parapatellar (LMPP) and mini-midvastus (MMV) approaches in 30 patients who had bilateral simultaneous primary TKAs. Each patient underwent LMPP on one knee and MMV on the other. Both approaches were navigation-assisted. We primarily analyzed postoperative pain (using visual analog scores), range of knee motion, and hospital for special surgery (HSS) scores in the first 6 postoperative months (i.e., the early postoperative period), and secondarily analyzed perioperative parameters and radiographic outcomes. The LMPP and MMV approaches were found to be similar in terms of pain measured at postoperative 3 days, 1, 2 weeks, 1, 3, and 6 months (P = NS). Similarly, the 2 approaches were found to be similar in terms of range of motion measured at 1, 2 weeks, 1, 3, and 6 months (P = NS), and in terms of HSS scores measured at 1, 3, and 6 months (P = NS). There were also no differences between groups in terms of total blood loss, approach preferred by patients, and radiographic component positioning. The present study found that navigation-assisted MMV and navigation-assisted LMPP resulted in similar outcomes in terms of pain, ROM, HSS score, and radiologic outcomes over the first six postoperative months. We recommend the LMPP approach over the MMV approach in navigation-assisted MIS TKA because it is more familiar to surgeons and is easier to convert to the conventional approach where necessary.
