Mid-to-long-term outcomes of posterior-stabilized type total knee arthroplasty in asian patients: A single-center retrospective cohort study.

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: Total knee arthroplasty (TKA) is a widely performed orthopedic procedure, yet patient satisfaction remains suboptimal, especially in Asian populations due to implant size mismatches. The FINE total knee prosthesis was anatomically designed for Japanese patients and incorporates medial pivot mechanics. However, mid-to-long-term outcomes of the posterior-stabilized (PS) type remain unreported. Methods: We retrospectively analyzed 247 consecutive primary TKAs performed using the PS-type FINE prosthesis at our institution between 2010 and 2017. Patients with at least 5 years of follow-up were included. Clinical outcomes were evaluated using the Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and passive range of motion (ROM). Radiographic assessments included femorotibial angle (FTA), hip-knee-ankle angle (HKAA), and radiolucent line evaluation. Implant survivorship was analyzed using Kaplan-Meier methods. Results: A total of 114 knees (84 patients) met the inclusion criteria with a mean follow-up of 112.2 months. Passive ROM improved significantly (extension from -8.9° to -2.6°, flexion from 121.4° to 124.5°). Favorable improvements in KSS and KOOS were observed. Radiolucent lines ≥2 mm were found in only 4.4 % of tibial zones and none on the femoral side. No revisions were required. Four knees (3.5 %) underwent reoperation for non-mechanical complications. The 10-year reoperation-free survival rate was 95.4 %. Conclusion: The PS-type FINE prosthesis demonstrated excellent mid-to-long-term clinical and radiographic outcomes in Asian patients. Its anatomical design and material properties contribute to its durability and functional success, supporting its use in population-specific TKA strategies.
