Final answer:
In ACL reconstruction, the patella and femur are the bones involved in a patella harvest. The patellar ligament attached to the patella is used in the procedure, with attachment points drilled into the femur and tibia.
Step-by-step explanation:
The bones involved in a patella harvest for an ACL reconstruction are the femur and patella. Arthroscopic surgery for ACL reconstruction typically utilizes a portion of the patellar ligament, which is attached to the patella itself and the tibia, but the bone that is actually harvested in this procedure is the patella.
Holes are then drilled into the tibia and femur to attach the patellar ligament graft. Therefore, the correct answer is d) Femur and patella.
