Assessing Functional Outcomes and Pain Intensity Variations After Total Knee Arthroplasty: A Comparative Analysis of Pain Block Techniques.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05478005 (Comparison of Function and Pain Intensity in the Acute Stage Following Total Knee Replacement, Between Different Methods of Post-surgical Pain Relief), 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
objectiveThis study aimed to compare post-total knee arthroplasty (TKA) outcomes (function, pain, and quadriceps strength) between femoral nerve block (FNB), intra-articular block, and a control group. In addition, it sought to identify predictors of postoperative functional capacity.
methodsFifty-four TKA patients were evaluated. Preoperative assessments included quadriceps strength and the Oxford knee score. Postoperative assessments on days 1 and 3/4 included the timed up and go (TUG), Elderly Mobility Scale, and Five Times Sit-to-Stand tests. Pain levels, hospitalization duration, surgical time, complications, and falls were also recorded.
resultsNo significant differences in functional outcomes, pain levels, or quadriceps strength were found between the FNB, intra-articular block, and control groups, except for the TUG test on day 3/4, which favored FNB (P < 0.01). Preoperative quadriceps strength was a valuable predictor of early functional outcomes, with FNB improving TUG scores on day 3/4. DISCUSSION: The choice of pain block technique had limited effect on short-term functional outcomes post-TKA, except for early mobility as measured by the TUG test on day 3/4. Preoperative quadriceps strength markedly predicted initial functional performance. Additional research is needed to enhance postoperative pain management and early rehabilitation strategies.
