Results of trabecular metal acetabular reconstruction in two-stage revision of infected total hip arthroplasty with large bone defect.

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
introductionTwo-stage revision of total hip arthroplasty (THA) remains the gold standard for periprosthetic joint infection (PJI). Trabecular Metal (TM) offers a valuable option for acetabular reconstruction, but evidence in septic revision THA (rTHA) is scarce. This study evaluated outcomes of TM implants in two-stage rTHA for infection, hypothesizing results comparable to existing literature, especially in cases with major bone loss. MATERIALS AND
methodWe retrospectively analyzed 32 two-stage rTHA (32 patients) performed between January 2010 and July 2021, with a minimum two years follow-up. All patients received TM acetabular implants. Bone loss was classified according to Paprosky: 3 IIA, 8 IIB, 3 IIC, 12 IIIA, and 6 IIIB, with pelvic discontinuity in 13 cases.
resultsAt mean follow-up of 30.2 ± 10.9 months (range, 24 to 69), infection eradication was achieved in 87,5%. Staphylococcus species accounted for 84,4% of cases. Seven complications occurred, including six reoperations: five revisions (two for recurrent infection, 3 for mechanical failure). The overall failure rate was 21,9%. At 24 months, the healing rate, including all causes of failure, was 78,1% and revision-free rate 84,4%.
conclusionTM implants in two-stage rTHA for septic failure achieved satisfactory mid-term results, even in advanced acetabular bone loss (44% Paprosky II, 56% Paprosky III). To our knowledge, this is the first study exclusively evaluating TM in this context, supporting its role in complex acetabular reconstruction during septic revisions. LEVEL OF EVIDENCE: IV.
