Factors Associated with Quadriceps Strength Recovery at 6 and 12 Months After Anterior Cruciate Ligament Reconstruction Using Quadriceps Tendon-Bone, Bone-Patellar Tendon-Bone, and Hamstring Tendon Autografts

The authors aimed to identify factors influencing quadriceps strength recovery at 6 and 12 months following anterior cruciate ligament reconstruction (ACLR) using different autograft types. They found that the use of quadriceps tendon-bone and bone-patellar tendon-bone autografts, meniscal repair, and lower preinjury activity levels were associated with increased risk of quadriceps strength deficits at 6 months, while lower preinjury activity levels and pain scores at 3 months were linked to deficits at 12 months.
