Arthroscopic matched osteoplasty of the radial head for painful radiocapitellar osteoarthritis: surgical technique and case series.

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
backgroundRadiocapitellar arthritis can cause pain, loss of motion, and impaired elbow function. Current surgical treatment options are limited. We have developed an original and simple surgical technique to address this, called arthroscopic matched osteoplasty of the radial head (AMOR). In AMOR, the radial head is partially resected and recontoured to match the capitellum and decompress the degenerate radiocapitellar articulation while preserving the ulnohumeral articulation where the cartilage is usually well preserved.
methodsIndications and the surgical technique of the AMOR procedure are described. A retrospective observational service evaluation study was conducted from electronic patient records. Collected clinical outcomes included range of motion, pain level, subjective functional score, and general satisfaction with the results of the procedure. The radiographic outcome was radiocapitellar joint space.
resultsBetween 2017 and 2021, eight consecutive patients underwent AMOR as part of an arthroscopic osteocapsular arthroplasty procedure. Radiographically, the mean radiocapitellar joint space improved from an average of 1.7 mm to 4.6 mm. Clinically, the mean pain score decreased from 8/10 to 3/10. Six of the eight patients (75%) were satisfied with their results. In two cases, initial improvement following surgery lasted less than 1 year, and one of these patients underwent total elbow arthroplasty for painful ulnohumeral osteoarthritis. There were no complications of surgery recorded.
conclusionsAMOR is a safe treatment option for painful radiocapitellar osteoarthritis and can be incorporated as an "add-on" procedure by surgeons performing elbow osteocapsular arthroplasty in cases with a positive grip and grind test and radiographic evidence of radiocapitellar OA. Level of evidence: IV.
