Clinical outcome, functional outcome and patient satisfaction after cruciate retaining total knee arthroplasty for stiff arthritic knee - A short term outcome study.
Article in Journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundVarious authors have shown that Cruciate Retaining (CR) Total Knee Arthroplasty (TKA) has better long-term survivorship compared to Posterior Stabilized (PS), however most arthroplasty surgeons tend to use PS knees in patients with severe deformity and stiffness. There is limited data correlating stiffness and CR versus PS design. The aim of our study was to assess the outcome of CR TKA for patients with stiff arthritic knee. MATERIALS &
methodsWe evaluated the results of 30 knees with osteoarthritis and inflammatory arthritis and preoperative stiffness (ROM 15-90°), who had been treated with CR TKA with a mean follow up of 2 years. The primary outcome variable measures were improvement in the flexion, flexion deformity (FFD) and overall improvement in the arc of motion. Patients were also evaluated by Knee Society Score (KSS), WOMAC score and 5-point Likert scale for patient satisfaction.
resultAt the time of final follow-up, the mean arc of motion improved from 75° preoperatively to 108° postoperatively and it was statistically significant (p < 0.001). Similar improvement was noted for FFD (15.43° to 0.83° (p < 0.001)), maximum flexion from 90.9° to 109.1° (p < 0.001), KSS clinical from 37.67 to 87.47 (p < 0.001), KSS functional from 58.5 to 93.83 (p < 0.001), WOMAC from 76.73 to 7.63 (p < 0.001). Further, the Likert Scale for patient satisfaction was excellent for 90% of the patients.
conclusionThis study clearly shows that the routine use of PS design for complex stiff knees has questionable scientific intent and standard CR TKA design in stiff knees can produce excellent outcome. Since there is slight preponderance of data pointing towards improved longevity with CR design, it would be a better option for the patients with longer life expectancy.
