Targeted adjustment of the posterior tibial slope in unicompartmental knee arthroplasty is feasible without altering the medial proximal tibial angle.

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
Purpose: Recommendations regarding the surgical modification of the medial posterior tibial slope (mPTS) in medial unicompartmental knee arthroplasty (UKA) vary. Given the high preoperative variability, this often results in a significant change in the patient's mPTS through UKA. However, it is unclear whether this change in mPTS impacts the coronal alignment, specifically the medial proximal tibial angle (MPTA). Therefore, the purpose of this study was to report on the preoperative to post-operative changes in mPTS and MPTA and their potential correlation in UKA. Methods: Pre- and post-operative radiographs of 96 consecutive patients undergoing conventional medial UKA were analyzed. Pre- and post-operative mPTS and MPTA were measured on radiographs by two observers and reported. Their differences, as well as the difference from the target value of 7°, were analyzed. Cases were grouped regarding their mPTS change into cases with <3° and cases with ≥3° mPTS change, and the correlation between changes in mPTS and changes in MPTA was reported. Results: The mean mPTS was reported at 9.27° (standard deviation [SD], 3.41°) preoperatively and 7.25° (SD, 2.23°) post-operatively, with a mean change of -2.02° (SD, 3.84°; Conclusions: Targeted mPTS modification can be achieved, which implies a significant change from preoperative mPTS values in patients undergoing UKA. However, the change in mPTS does not affect the change in MPTA. Level of Evidence: Level III.
