Conversion of fused hips to cementless total hip arthroplasty long-term (23.5 years) functional outcome, survival and patient satisfaction.

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
purposeOur retrospective study focused on long-term outcomes of converting a fused hip to a cementless metaphyseal-fitting anatomic hip system including: (1) validated clinical scores; (2) radiographic assessment; (3) impact on neighbouring joints; (4) osteolysis and revision rates; (5) complication profiles; (6) implant survivorship; and (7) patient satisfaction.
methodsWe reviewed 96 THAs in 88 patients (mean age, 42.3 years [range, 21 to 74]) who underwent conversion of fused hip through a posterolateral approach to a cementless a metaphyseal-fitting anatomic cementless total hip system, performed by one surgeon. The third generation Biolox Forte at 28 mm as the bearing surface was used in all hips. The mean follow-up was 23.5 years (range, 14 to 30 years).
resultsAt the final follow-up, the mean Harris hip score was 91.2 points (range, 52 to 100 points). Mean hip flexion was 89° (range, 70° to 120°). Three acetabular (3%) and five femoral components (5%) that were revised. About 70 to 80% of patients expressed overall satisfaction and 66% of patients reported marked improvement in quality of life. A Kaplan-Meier survivorship analysis at 23.5 years showed a 97% survival rate (95% CI, 93 to100%) for the acetabular component and 91% (95% CI, 89 to 98%) for the femoral component.
conclusionsConversion of hip fusion to THA using metaphyseal-fitting anatomic cementless hip system appears to provide good long-term outcomes. The risk for postoperative complication including abductor dysfunction and nerve injury should be carefully discussed with patients prior to surgery.
