Harvesting the patellar tendon
The central one third of this tendon can be 'harvested', together with a bone block at each end - the upper block from the patella (kneecap) itself and the lower block from the tibia bone (shin). This harvested tendon is thus 'bone-patellar tendon-bone' in structure.

"Anterior cruciate ligament reconstruction with bone–patellar tendon–bone autograft....[is] a reliable graft and is the preferred option for competitive athletes given its excellent track record with high return-to-play rates and low failure rates. Disadvantages to using this graft include donor site morbidity and associated postoperative anterior knee pain, the risk of patellar fracture or patellar tendon tear, and the potential for graft-construct mismatch."
