Results Muscle Strength and Thickness After Anterior Cruciate Ligament Reconstruction with Hamstring Tendon Autografts: An Ultrasonographic and Isokinetic Evaluation

Abstract

BACKGROUND/AIMS: This study aimed to compare the muscle strength and thickness of individuals who underwent anterior cruciate ligament (ACL) reconstruction using a hamstring tendon graft for at least 12 months with uninvolved limbs and healthy controls. MATERIALS and METHODS: This study included 25 individuals who underwent ACL reconstruction [age: 29.56±8.25 years; Body Mass Index (BMI): 27.27±3.89 kg/cm2] and 25 healthy participants (age: 27.12±5.94 years; BMI: 24.70±3.03 kg/cm2). Muscle thicknesses of the vastus medialis oblique (VMO), rectus femoris (RF), biceps femoris (BF), and semitendinosus-semimembranosus (SS) muscles were evaluated by ultrasonographic measurement. Muscle strength measurements using an isokinetic system were performed. RESULTS: VMO (p0.05). CONCLUSION: An average of 3 years has passed since the operation; however, VMO and RF muscle atrophy and decreased hamstring and quadriceps muscle strength continued. These results revealed that the use of the limb, which has not fully achieved its functionality, is limited, and individuals try to compensate for this situation by the uninvolved limb.
