Comparison of the minimally invasive and standard medial parapatellar approaches for primary total knee arthroplasty.
Synthesis in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02516280 (Effects of Hyperbaric Gaseous Cryotherapy on Knee Flexion Range of Motion in the First Two Days After Total Knee Arthroplasty), which is not on this map.

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.

Abstract
purposeThe minimally invasive surgical (MIS) approach has been popularised as an alternative to the standard medial parapatellar approach (MPP) in total knee arthroplasty (TKA). Advocates of this technique suggest earlier functional recovery due to less injury to the surrounding tissues. Potential disadvantages however may include reduced overall exposure, component malalignment and damage to neurovascular structures.
methodsA systematic review and meta-analysis of randomised and quasi-randomised trials were conducted to compare the MIS and MPP approaches in primary TKA. Methodological features were rated independently by two reviewers.
resultsSeventeen studies were included involving 733 patients with mean age of 69 (SD ± 2.8) in the MIS group and 692 patients with mean age of 68.6 (SD ± 3.1) in the MPP group. Using a MIS approach led to significant increase in flexion within the first week after a TKA (mean difference (MD) of 9.9° (95% confidence interval (CI) 8.2-11.6, P < 0.01)). However, this effect was not sustainable at further follow-ups of ≥ 3 months. MIS showed a significantly increased risk of developing intraoperative complications with a risk ratio (RR) of 7.6 (95% CI 3.5-16.3, P < 0.01).
conclusionMIS results in superior function in the immediate postoperative period after a primary TKA but is also associated with increased rates of intraoperative complications, and therefore, a standard approach that allows adequate exposure and avoids tension to the wound edges would be more appropriate to prevent such complications. LEVEL OF EVIDENCE: Therapeutic study, Level I.
