Higher body mass index adversely affects knee function after anterior cruciate ligament reconstruction in individuals who are recreationally active

摘要: Objective:Our aim was to investigate the effect of body mass index (BMI) levels on quadriceps and hamstring strength and functional outcomes up to 6 months after anterior cruciate ligament reconstruction (ACLR) with hamstring tendon autograft (HTG).Design:Prospective, controlled study.Setting:University clinical laboratory.Patients:Ninety-one participants who had undergone unilateral ACLR with HTG were divided into 2 groups according to their BMI. The participants whose BMI were between 18.5 and 24.9 kg/m 2 were included in group 1 (n= 50, age: 27.2±6.7 years, BMI: 22.3±1.6 kg/m 2) and those whose BMI> 24.9 kg/m 2 were included in group 2 (n= 41, age: 30.2±6.9 years, BMI: 28.0±2.4 kg/m 2).Interventions:Quadriceps and hamstring strength, functional performance including hop, jump, and balance performance, and IKDC score.Main Outcome Measures:Maximum voluntary isometric contraction of the …
