[The use of tantalum cones for reconstruction of bone defects in revision total knee arthroplasty].
Trial report in Operative Orthopadie und Traumatologie, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveRevision arthroplasty of the knee is often associated with substantial femoral and/or tibial bone loss. Tantalum cones are used to reconstruct these defects and to improve initial stability. This requires an implantation in the "press-fit" technique with maximum contact to the host bone. INDICATIONS: Tantalum cones may be used in grade 2-3 femoral and/or tibial defects according to the AORI (Anderson Orthopedic Research Institute) classification system. CONTRAINDICATIONS: There are no contraindications described. SURGICAL TECHNIQUE: After removal of the implant and cement remnants, bone defects have to be evaluated. A tantalum cone which adequately fills the bone defect is implanted using the "press-fit" technique. If necessary, saving resection of surplus bone to fit the cone properly. Gaps between the cone and the host bone are filled with cancellous bone in "impaction-bone-grafting" technique to increase the area of contact. Fitting the revision knee prosthesis and fixing with the use of bone cement. POSTOPERATIVE MANAGEMENT: Postoperative physiotherapy is adjusted to the result of the reconstruction. In most cases with stable reconstruction, mobilization with full weight-bearing and the use of two crutches can be performed. Additional bone grafting may require a partial weight-bearing regimen for postoperative mobilization. Physiotherapy to improve range of motion is performed starting on postoperative day 1.
resultsSeveral studies reported promising midterm results (observation period about 36 months) after implantation of tantalum cones in revision knee arthroplasty. There is consistent evidence for stable osteointegration of the cones. The main intraoperative complication is fracture of the host bone during impaction of the cones.
