Patients undergoing minimally invasive periacetabular osteotomy demonstrate improved outcomes: a systematic review.
Review in Journal of hip preservation surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Periacetabular osteotomy (PAO) has demonstrated favourable outcomes for the treatment of acetabular dysplasia. Minimally invasive (MI) PAO uses a smaller incision to preserve soft tissue, minimize complications, and accelerate recovery; however, the outcomes of MI PAO are still being established. The purpose of this study was to conduct a systematic review to assess the reoperation rates and patient-reported outcomes following MI PAO. A systematic review of the literature was conducted in PubMed, CENTRAL, and Scopus in April 2024 with the following keywords: (mini*) AND (periacetabular osteotomy"). The PRISMA criteria were used. Only studies that reported on patient-reported outcome measures (PROMs) of MI PAO techniques were included. Eight studies with study periods ranging between 2004 and 2021 including a total of 2247 hips were included in this review. Mean follow-up ranged from 12 to 60 months. The mean age at the time of surgery ranged from 20.0 to 38.7 years, and 85.6% of included hips were from female patients. Seven out of 8 included studies reported significant improvement in preoperative vs postoperative PROMs. The mean Non-Arthritic Hip Score ranged from 49.8 to 58.7 preoperatively compared to 77.2-89.4 postoperatively. Mean UCLA scores ranged from 3.9 to 4.67 preoperatively to 6.3-6.97 postoperatively. Mean Harris Hip Scores ranged from 50.8 to 66 preoperatively compared to 87.4-93 postoperatively. Conversion to THA rates ranged from 0% to 5.3% at a mean of 4.9 years (0.6-14). Patients undergoing MI PAO surgery for the treatment of acetabular dysplasia demonstrated low rates of conversion to THA and significant improvement in PROMs at short- to mid-term follow-up.
