Controlled prospective cohort study (n=180) following patients 10 years after ACL reconstruction with either 4-strand hamstring tendon (HT) or patellar tendon (PT) autograft, performed by a single surgeon with identical fixation and rehabilitation. Asks whether graft choice affects long-term graft survival, knee function, donor-site morbidity, and radiographic osteoarthritis.
When counseling patients on ACL graft choice, this study supports hamstring autograft as the preferred option — equivalent graft survival with less donor-site morbidity, less kneeling pain, and less radiographic osteoarthritis at 10 years.
When you see a KT-1000 side-to-side difference >2 mm at the 2-year mark, recognize that as a meaningful predictor of eventual graft failure and factor it into surveillance planning.
