Standing Flexion Deficits Predict Self-Reported Outcomes in Women After Ipsilateral Hamstring Anterior Cruciate Ligament Reconstruction

摘要: Purpose To profile the standing flexion angle and its association with subjective outcomes in ipsilateral hamstring tendon autograft anterior cruciate ligament–reconstructed patients. A secondary aim was to describe prone position–measured strength as a predictor of angle. Methods Fifteen women (mean age, 20.47 ± 1.96 years; mean height, 1.69 0.08 m; weight, 68.51 12.64 kg; Tegner score, 6.80 1.52), at 25.93 11.25 months after surgery, were matched 15 healthy participants by sex approximate mass, activity level 20.93 1.22 1.65 0.06 66.52 10.69 6.13 1.06). The independent variable leg condition (involved, uninvolved, or matched). Dependent variables included goniometric angle, Knee Injury Osteoarthritis Outcome Score (KOOS) subscale scores, absolute isokinetic strength. We used 1-tailed paired 2-sample t tests analyze side group differences, respectively. Corresponding effect sizes ( d ) also quantified. Linear regression assessed relations between KOOS, well P Results involved showed significantly lesser (112.9° 8.1°) compared uninvolved (116.1° 8.4°,  = .024) (117.1° 4.5°, .044), corresponding weak 0.380) strong 0.958) sizes. Significant associations existed r 2 60.3% .001 for KOOS pain subscale, 37.8% .015 function activities daily living, 39.2%  = .012 sports recreation) leg. Hamstring not significant all legs > .05). Conclusions Our results support hypotheses that insufficiencies exist leg, superior are associated greater capacity, deep knee angles does predict Level Evidence IV, therapeutic study, case series.
