Comparative Postoperative Changes Over Time in Patellar Height After Medial Patellofemoral Ligament Reconstruction With and Without Tibial Tubercle Osteotomy.

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
Background: The postoperative influence of medial patellofemoral ligament reconstruction (MPFLR)-performed alone or in conjunction with tibial tubercle osteotomy (MPFLR+TTO)-on patellar height is not well-understood. Purpose/Hypothesis: The purpose was to compare longitudinal changes in patellar height after MPFLR and MPFLR+TTO. It was hypothesized that knees undergoing MPFLR will experience a decrease in patellar height that is greater than that of knees undergoing MPFLR +TTO and that both cohorts will return to Caton-Deschamps index (CDI) measures near that of preoperative levels. Study Design: Cohort study; Level of evidence, 3. Methods: This is a retrospective radiographic review of skeletally mature patients >15 years of age who underwent either an MPFLR or an MPFLR+TTO with lateral knee radiographs available from the preoperative period, 0 to 6 months (early) postoperatively, and >6 months (final) postoperatively. Exclusion criteria were (1) distalization TTO and (2) previous procedures, or procedures postoperatively near the extensor mechanism. CDI was used to quantify patellar height. Paired Student Results: A total of 62 knees in 61 patients (55% female [34/62 knees]) were included, with n = 27 knees undergoing MPFLR and n = 35 knees with MPFLR+TTO. Mean age was 25.9 ± 9.8 years (range, 15-58 years). Mean time from surgery to early postoperative imaging was 1.9 ± 1.4 months with MPFLR and 2.4 ± 0.8 months with MPFLR+TTO ( Conclusion: Our study showed that MPFLR both with and without TTO demonstrated an eventual return toward preoperative patellar height, yet they followed different early postoperative trajectories. MPFLR demonstrated an early decrease in patellar height that progressively relengthened over time, whereas MPFLR+TTO exhibited almost no changes in patellar height.
