DOES THE GRAFT USED FOR ACL RECONSTRUCTION AFFECT THE KNEE MUSCULAR STRENGTH RATIO AT SIX MONTHS POSTOPERATIVELY?
Article in International journal of sports physical therapy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundRestoring knee muscle strength after an anterior cruciate ligament (ACL) reconstruction remains challenging. Improvement of rehabilitation program specificity demands additional knowledge on knee muscle strength deficits associated with the graft used for ACL reconstruction. PURPOSE: This study aimed to investigate the effects of graft used for ACL reconstruction on the knee muscle strength and balance assessed at six months postoperatively, based on comparisons of the isokinetic strength curves measured throughout knee extension. STUDY
designCross-sectional study.
methodsOne-hundred-and-forty-four patients were assigned into three groups according to the graft used for a primary ACL reconstruction: semitendinosus (n=47), semitendinosus+gracilis (n = 75) and patellar (n=22) tendon graft. Normalized hamstring eccentric and quadriceps concentric torques, and hamstrings-to-quadriceps torque ratio (defined as the dynamic functional ratio) were bilaterally assessed during knee extension. Statistical parametric mapping was used to compare the curves of torques and ratio from 90 ° to 30 °of knee flexion between groups.
resultsThe uninvolved knees presented similar strength and ratio curves in the three groups. When compared involved to uninvolved knees, hamstring strength deficit was found in hamstring tendon groups throughout knee extension (p<0.001), and quadriceps strength deficit in the three groups throughout knee extension (p<0.001). Hamstrings-to-quadriceps torque ratio was unaltered when using hamstring tendon grafts, while increased ratio was observed up to knee mid-extension when using patellar tendon graft (p<0.001).
conclusionsThese findings suggest exercises with specific range of motion and contraction type in relation to graft may be considered for implementation into postoperative rehabilitation program in order to eliminate the regional strength deficits observed after ACL reconstruction. LEVEL OF EVIDENCE: 3.
