Efficacy of Active Exercises to Improve Range of Motion in Knee Joint After Total Knee Arthroplasty. A Randomized Controlled Trial.
Trial report in Physiotherapy research international : the journal for researchers and clinicians in physical therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06188091 (Impact of Active Joint Movement to Increase Range of Motion in Knee Joint After Primary or Revision Total Knee Arthroplasty), which is not on this map.

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
background and purposeAfter total knee arthroplasty (TKA), not everybody gains a sufficient joint mobility. The objective of this study was to investigate the effects of high-frequency (HF) versus low-frequency (LF) self-managed knee flexion exercises in individuals with reduced flexion after a TKA.
methodsThe study was a randomized controlled trial in adults with a TKA within 6 to 26 weeks and knee flexion ≤ 105° who participated in an 18-day inpatient rehabilitation program. Patients were randomized to additional self-managed HF (eight flexion and extension exercises per day) versus LF (two flexion and extension exercises per day). The primary outcome was knee flexion change. Secondary outcomes were changes of knee extension, Six-Minute Walk Test, 30 Second Chair-Stand Test, pain using Numeric Rating Scale, and Knee Injury and Osteoarthritis Outcome Score.
resultsThe participants (n = 83) were 65 (SD 8.8) years old and 70% were women. The HF (n = 44) and LF (n = 39) groups performed knee flexions 5.3 (1.4) and 1.7 (0.3) times/day, respectively. The flexion increased 14.2 [11.6; 16.7]° with HF versus 10.1 [8.6; 11.6]° with LF, with 4.1° difference between groups (p = 0.007). Secondary outcomes increased in the two groups without differences between the groups. DISCUSSION: In individuals with reduced joint mobility after TKA, HF self-managed knee flexion exercises were associated with a positive change in flexion compared with LF, though the between-group difference was smaller than expected. TRAIL REGISTRATION: The study was registered on ClinicalTrials.gov (NCT06188091).
