That's what I thought - they still used the traditional hamstring tendon for the graft, as opposed to LARS surgery which involves using a synthetic fibre cable as the replacement graft for the torn ligament. LARS tends to heal quicker but is prone to snapping easier than a traditional hamstring tendon graft.
Back in the early 90's I had a knee reco done, but the traditional procedure back then was to use the patella (kneecap) tendon as the replacement graft. It created a lot more scar tissue and instability because the patella only has 3 tendons (as opposed to the 5 tendons in the hamstring) and they would use the tendon from the patella right next to the torn ligament. My graft is still solid 20 years later but there is excess wear and tear from the scar tissue, not to mention a few extra kgs being carried by my knee since then
