Outcomes After Medial Quadriceps Tendon Femoral Ligament Reconstruction in Adolescent Patients.
Article in Orthopaedic journal of sports medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Recurrent lateral patellar instability is common in adolescent patients, often requiring surgical intervention. Medial quadriceps tendon femoral ligament reconstruction (MQTFLR) has emerged as an alternative to medial patellofemoral ligament reconstruction, avoiding patellar fixation and its associated complications. However, data on short-term clinical outcomes and return to activity (RTA) following MQTFLR in adolescent patients remain limited. Purpose: To evaluate short-term clinical outcomes and RTA following MQTFLR in adolescent patients with recurrent lateral patellar instability. Study Design: Case series; Level of evidence, 4. Methods: Adolescent patients (≤19 years) who underwent primary allograft MQTFLR at a single institution between 2017 and 2023 were retrospectively reviewed. Inclusion criteria required both pre- and postoperative patient-reported outcomes (PROs) with a minimum 1-year follow-up. The primary outcome was the change from baseline in PROs, including scores on the Pediatric International Knee Documentation Committee Subjective Knee Evaluation Form (Pedi-IKDC), the Tegner Activity Scale, and the Lysholm Knee Scoring Scale. RTA rates and complications were also assessed. A Wilcoxon signed-rank test was used to compare pre- and postoperative PROs, with Results: A total of 43 patients (mean age 15 ± 1.8 years, 58% female) underwent MQTFLR. Multiple preoperative dislocations were reported in 63%, and 23% underwent simultaneous tibial tubercle osteotomy. Median follow-up was 24.0 months (IQR, 12.6-24.3). RTA data were available for 33 patients, with 82% attempting to return to their primary activity and 89% of those returning at the same or higher level. Statistically significant improvements were observed in Pedi-IKDC (58.70 [50.55-67.94] to 95.65 [80.98-98.37]; Conclusion: MQTFLR is a safe and effective surgical option for adolescent patients with recurrent lateral patellar instability, resulting in significant improvements in PROs and a high rate of RTA at the same or higher level. Further research is needed to assess long-term outcomes and identify factors that may influence postoperative recovery.
