Medial Patellofemoral Ligament Reconstruction vs Nonoperative Treatment for Recurrent Lateral Patellar Dislocation: Three-Year Results From a Randomized Controlled Trial.
Trial report in The American journal of sports medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02263807 (RCT Study), which is not on this 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.

Abstract
backgroundMedial patellofemoral ligament reconstruction (MPFL-R) is the primary surgical intervention for recurrent lateral patellar dislocation (LPD). Isolated MPFL-R is recommended for patients without anatomic high-risk factors that predispose to further dislocations. PURPOSE: To compare instability recurrence in patients with recurrent LPD without underlying anatomic risk factors treated with MPFL-R versus active rehabilitation. STUDY
designRandomized controlled clinical trial; Level of evidence, 1.
methodsPatients aged 12 to 30 years with recurrent LPD and no underlying anatomic high-risk factors for further dislocations-specifically, no severe trochlear dysplasia (Dejour D) and a tibial tuberosity-trochlear groove distance ≤20 mm on computed tomography-were randomized to receive knee arthroscopy with isolated MPFL-R followed by active rehabilitation (MPFL group) or knee arthroscopy without reconstruction followed by active rehabilitation (control group). The primary outcome was subjective persistent patellar instability at 3 years. Knee function at baseline and 1 and 3 years was assessed by the following patient-reported outcome measure (PROM) scores: Knee injury and Osteoarthritis Outcome Score (KOOS), Kujala Knee Score, Cincinnati Knee Rating System, and Noyes Sports Activity Rating Scale.
resultsBetween 2010 and 2019, 61 patients (72.1% female) were included in the study and randomized, with 30 assigned to the MPFL group and 31 to the control group. At 3-year follow-up, subjective persistent patellar instability was reported by 5 patients in the MPFL group (16.7%) versus 15 patients in the control group (53.6%), corresponding to an odds ratio of 5.8 (95% CI, 1.7-19.4;
conclusionIsolated MPFL-R was more effective than active rehabilitation alone in preventing patellar instability after 3 years.
